CleanTech Biofuels, Inc. - Quarter Report: 2010 March (Form 10-Q)

Note 2 — Recent Accounting Pronouncements

In January 2010, the FASB issued an amendment to the fair value measurement and disclosure standard improving disclosures about fair value measurements. The guidance requires additional disclosure for transfer activity pertaining to Level 1 and 2 fair value measurements and purchase, sale, issuance, and settlement activity for Level 3 fair value measurements. The guidance for the Level 1 and 2 disclosures was adopted on January 1, 2010 and did not have an impact on our consolidated financial statements. The guidance for the activity in Level 3 disclosures is effective for fiscal years beginning after December 15, 2010. The Company had no transfers between Level 1, 2 or 3 inputs during the quarter ended March 31, 2010.

Note 3 — Mergers/Acquisitions

On September 15, 2008, the Company consummated the acquisition of Biomass North America Licensing, Inc. (“Biomass”) pursuant to a merger between Biomass and a wholly-owned subsidiary of the Company (with Biomass as the surviving subsidiary of the Company) in accordance with an Agreement and Plan of Merger by and between the Company and Biomass. By virtue of the merger, the Company acquired a license agreement pursuant to which the Company holds a license in the United States and Canada to use patent pending technology owned by Biomass North America, LLC, the former parent of Biomass (the “Licensor”), to clean and separate municipal solid waste (the “Biomass Recovery Process”).

Upon consummation of the merger, the Company paid $20,000 in cash and issued a promissory note in the original principal amount of $80,000 bearing interest at an annual rate of 6% (the “Note”) to a shareholder of the Licensor. This note has been paid in full. Additionally, the Company issued to the four shareholders of the Licensor a total of 1,895,000 shares of Common Stock and deposited an additional 4,000,000 shares of Common Stock into an escrow account (collectively, the “Shares”). The Shares were issued as part of the merger consideration received by the shareholders of the Licensor. The escrowed shares will be released to the Licensor’s shareholders if and when the Company commences a commercial development that utilizes the Biomass Recovery Process. The Company recorded a long-term asset of $1.5 million which it will begin to amortize upon utilizing the license in our operations. If the escrowed shares are released based on the specified future events, an increase to the value of the asset will be recorded at that time. Based on the market value of Common Stock as of March 31, 2010, it would result in an increase of approximately $360,000 to the asset. Any future increase in the value of the asset would depend on the market value of our Common Stock at the time of utilization.

Note 4 — Patent

On October 22, 2008, the Company completed the purchase of Patent No. 6,306,248 (the “Patent”) pursuant to a Patent Purchase Agreement (“Agreement”) with World Waste Technologies, Inc. (“WWT”). The Patent is the basis for a pressurized steam classification technology from which our Biomass Recovery Process was developed. As part of the acquisition of the Patent, we also became the licensor of such technology to Bio-Products International, Inc. Upon signing the Agreement, the Company paid WWT $150,000, issued a note in the amount of $450,000 (6.0% per annum and secured by a security interest in the Patent) and issued warrants to purchase 900,000 shares of Common Stock at a price of $0.45 per share and to purchase an additional 900,000 shares of Common Stock at a price of $0.45 per share contingent on payment of the note by July 22, 2009 (the original maturity date). WWT assigned all of its rights, title and interest in the note, warrants, security agreement and purchase agreement to Vertex Energy, Inc. (“Vertex”) as a result of a merger in March 2009. We entered into amendments dated July 23, 2009 whereby: (i) the Company paid 10% of the original note and all accrued interest to date, (ii) all previous warrants (totaling 1,800,000 shares) were reissued at a price of $0.11 per share with no contingencies and (iii) the remaining payments on the note were scheduled to be paid on October 22, 2009 (50% of principal plus accrued interest to date not yet paid) and January 22, 2010 (remaining principal and accrued interest to date). We entered into amendments dated October 22, 2009 whereby: (i) the October 22, 2009 payment was deferred until November 22, 2009 and (ii) we issued additional warrants to Vertex for 500,000 shares of Common Stock at a price of $0.10 per share. The warrants are exercisable at any time for five years from the date of issuance or reissuance. The cost of the patent acquisition of $600,000 is recorded as a long-term asset on the Balance Sheet. The value of the warrants has been recorded as a contra-balance amount with the note and is being amortized through interest expense over the life of the note. This note has been recorded as short-term debt (notes payable) in the financial statements, net of discounts for the warrant features. For the three months ended March 31, 2010 and 2009, amortization of this discount of approximately $7,000 and $58,000, respectively, has been recorded in interest expense. At March 31, 2010, the notes payable balance, net of the discount, related to this note is $173,000. As of May 12, 2010, all payments have been made except for approximately $185,000 in principal and interest. Final payment on the note was due January 22, 2010.

Note 5 — Technology Licenses

Biomass North America Licensing, Inc.

On September 15, 2008, in connection with the acquisition of Biomass described in Note 3 — Mergers/Acquisitions, we acquired a license in the United States and Canada to use patent pending technology owned by Biomass North America, LLC, the former parent of Biomass (the “Licensor”), to clean and separate municipal solid waste, which we refer to as the Biomass Recovery Process. As a result of the merger, a long-term asset of $1.5 million was recorded for the value of this license. Amortization of this asset will begin upon commencement of the use of the Biomass Recovery Process. The Company also deposited an additional 4,000,000 shares of the Company’s Common Stock into an escrow account. For accounting purposes, the shares remaining in escrow are not considered issued and outstanding as a project has not started using the Biomass Recovery Process. The shares are not deemed issued or vested until that time as described above. As of March 31, 2010, the approximate additional license value to be recorded upon issuing the remaining shares, based on the market value of our common stock at March 31, 2010, would be approximately $360,000. Any future increase in the value of the asset would depend on the market value of our Common Stock at the time of utilization.

The license requires that the Company pay a royalty in the amount of $1.00 per ton of bone-dry biomass produced using the Biomass Recovery Process. The license agreement is for a term of 21 years or the life of any patent issued for the Biomass Recovery Process. The Company has an exclusive license in the United States and Canada to use the Biomass Recovery Process, except that a principal owner of the Licensor has the right of first offer to manage and operate with respect to any development commenced using the licensed technology within 100 miles of the City of Chicago, Illinois. The license agreement further provides that Biomass and Licensor will work in good faith to complete a commercial development in the City of Chicago using the Biomass Recovery Process.

HFTA, Inc.

On March 20, 2008, the Company entered into a license agreement with HFTA, Inc. (“HFTA”) granting the Company the exclusive worldwide right to use the HFTA technology for the production of ethanol from MSW. The terms in the original agreement required us to pay an initial license fee of $25,000 to HFTA on execution of the agreement and a second license fee of $150,000 on September 1, 2009 if we were using the technology at that time. On August 24, 2009, we entered into an amendment with HFTA that moved the September 1, 2009 payment, plus interest at 6% per annum from the date of the amendment, to March 1, 2010.

Additionally, we deposited 2,887,687 shares of our Common Stock into an escrow account on May 12, 2008. The shares held in escrow were released to HFTA as follows: the first third of the shares (962,562 shares) were released from escrow on September 20, 2008 (six months from the date of the original agreement) and the remaining 1,925,125 shares were released upon the amendment in August 2009. As a result, the Company recorded an asset for the value of the first third share payment of approximately $500,000 in September 2008 and recorded an addition to the asset of approximately $190,000 related to the release of the remaining shares in August 2009. During the fourth quarter 2009, the Company decided not to use this technology going forward in our operations and thus wrote off the asset as of December 31, 2009. The impairment loss of approximately $690,000 is included in research and development expense on the statement of operations for the year ended December 31, 2009.

Bio-Products International, Inc.

On August 17, 2005, the Company entered into a license agreement with Bio-Products International, Inc. (“Bio-Products”) giving the Company limited exclusive rights to use Bio-Products technology (Patent No. 6,306,248) to process MSW and convert the cellulosic component of that waste to a homogenous feedstock to produce ethanol in the United States, subject to the right of Bio-Products to request five sites to construct MSW to ethanol plants in the United States. The Company’s license with Bio-Products was for a period of twenty years. Under the license, Bio-Products was to be paid a process royalty of $1.50 for every ton of waste received and processed at each facility to be constructed and operated under the agreement. The Company also was required to pay a by-product royalty of 2.5 percent of the gross sales price in excess of $10 per ton obtained from the sale of recyclable by-products, excluding the cellulosic biomass. Bio-Products would also have been paid a monthly fee for technical services to be provided by Bio-Products for each facility to be constructed and operated which initially would have been $10,000 per month and increase to $20,000 per month when vessels for processing waste are ordered for the facility. The $20,000 per month fee would have continued until construction of a facility was completed. The Company’s litigation involving Bio-Products was settled in March 2009 and as a result, this sublicense has been mutually terminated by all parties.

As disclosed in a previous footnote, the Company purchased Patent No. 6,306,248 (the “Patent”) pursuant to an Agreement with WWT. The Patent is the basis for the pressurized steam classification technology that cleans and separates MSW into its component parts, which we refer to as the PSC technology. The Company is now a licensor to Bio-Products for this Patent. Bio-Products is the exclusive licensee of the PSC technology (but not the Biomass Recovery Process) and has the right to sublicense the PSC technology to any party. Under the Master License Agreement, we are entitled to be paid 5% of any revenue derived by Bio-Products from the use of the technology and 40% of any sublicensing fees paid to Bio-Products for the use of the technology. The Master License Agreement is for a term of 20 years that commenced on August 18, 2003.

All intangible assets are reviewed for impairment whenever events or other changes in circumstances indicate that the carrying amount may not be recoverable. An impairment charge is recognized if the carrying amount of an intangible asset exceeds its implied fair value.

Convertible Notes Payable

During September 2008, the Company commenced an offering of units comprised of a convertible promissory note and a warrant. The Company raised a total of $642,000 of investment proceeds through March 31, 2009 and this offering is closed. As of March 31, 2010, all of these notes have either been converted to shares of our common stock or re-priced to our second convertible note offering (resulting in new notes with a total face value of $539,829, which included the original principal and interest through the date of re-pricing). Each convertible promissory note carried a one-year term and a 6% interest rate. In addition, each note could have been converted, at the note holder’s option, at any time during the one-year term into shares of Common Stock at $0.25 per share, or prior to the closing of any Qualifying Equity Financing (minimum capital received of $5 million). Each note was issued with a warrant to purchase additional shares of Common Stock equal to the principal amount of the promissory note at a price of $0.45 per share. These promissory notes had been recorded as short-term debt (notes payable) in the financial statements, net of discounts for the conversion and warrant features. The discounts were being amortized on a straight-line basis over the term of each note and are fully expensed as of March 31, 2010. For the three months ended March 31, 2010 and 2009, amortization of approximately $7,000 and $150,000, respectively, for these discounts has been recorded in interest expense. All warrants related to this offering of units remain outstanding at the original pricing.

During April 2009, the Company commenced another offering of units comprised of a convertible promissory note and a warrant. As of March 31, 2010, the Company raised a total of $1,063,500 of investment proceeds. One note was converted during the second quarter of 2009 leaving $1,038,500 face value of notes outstanding. Each convertible promissory note carries a one-year term and a 6% interest rate. In addition, each note can be converted, at the note holder’s option, at any time during the one-year term into shares of Common Stock at $0.08 per share, or prior to the closing of any Qualifying Equity Financing (minimum capital received of $5 million). Each note was issued with a warrant to purchase additional shares of Common Stock to provide for 100% coverage of the promissory note at a price of $0.30 per share. These promissory notes have been recorded as short-term debt (notes payable) in the financial statements, net of discounts for the conversion and warrant features. The discounts are being amortized on a straight-line basis over the term of each note. For the three months ended March 31, 2010 and 2009, amortization of approximately $79,000 and $0, respectively, for these discounts has been recorded in interest expense. This offering is continuing — see the Subsequent Events footnote for further information.

Vertex (formerly WWT) Note Payable

As disclosed previously, as part of the Patent purchase, the Company issued a note in the amount of $450,000 (6.0% per annum and secured by a security interest in the Patent) and issued warrants to purchase 900,000 shares of Common Stock at a price of $0.45 per share and to purchase an additional 900,000 shares of Common Stock at a price of $0.45 per share contingent on payment of the note by July 22, 2009 (the original maturity date). WWT assigned all of its rights, title and interest in the note, warrants, security agreement and purchase agreement to Vertex Energy, Inc. as a result of a merger in March 2009. We entered into amendments dated July 23, 2009 whereby: (i) the Company paid 10% of the original note and all accrued interest to date, (ii) all previous warrants (totaling 1,800,000 shares) were reissued at a price of $0.11 per share with no contingencies and (iii) the remaining payments on the note were scheduled to be paid on October 22, 2009 (50% of principal plus accrued interest to date not yet paid) and January 22, 2010 (remaining principal and accrued interest to date). We entered into amendments dated October 22, 2009 whereby: (i) the October 22, 2009 payment was deferred until November 22, 2009 and (ii) we issued additional warrants to Vertex for 500,000 shares of Common Stock at a price of $0.10 per share. The warrants are exercisable at any time for five years from the date of issuance or reissuance. The value of these warrants has been recorded as a contra-balance amount discount with the note and is being amortized through interest expense over the life of the note. For the three months ended March 31, 2010 and 2009, amortization of approximately $7,000 and $58,000, respectively, for this discount has been recorded in interest expense. As of May 12, 2010, all payments have been made except for approximately $185,000 in principal and interest. Final payment on the note was due January 22, 2010.

Series A Convertible Debentures

In April 2007, the Company sold $1,400,000 of Series A Convertible Debentures (“Debentures”), due April 16, 2010, that convert into shares of the Company’s Common Stock at $.15 per share. The Company filed a registration statement with regard to the sale of these shares of Common Stock, which was declared effective by the Securities and Exchange Commission on January 2, 2008. The debentures accrue interest at 6% per annum. The interest is payable in cash or shares of Common Stock at the Company’s option.

The Company received cash of $950,000 and Promissory Notes (“Notes”) with an aggregate principal amount of $450,000 that accrue interest at 6.0%. Effective with the listing of our Common Stock on the OTCBB on March 13, 2008 (previously traded on Pink Sheets) we received full payment on all principal and accrued interest on the Notes totaling approximately $475,000 on March 14, 2008.

During March 2008, various debenture holders converted an aggregate amount of $630,000 of our Debentures, plus interest earned, into 4,433,067 shares of our common stock. During April 2008, various debenture holders converted an aggregate amount of $630,000 of our Debentures, plus interest earned, into 4,455,844 shares of our common stock. These transactions converted in the aggregate $1,260,000 of our Debentures, leaving $140,000 remaining to be converted. As of March 31, 2010, $140,000 of our Debentures remained outstanding and eligible for conversion. See the Subsequent Event footnote for final conversion of all outstanding amounts.

Note 7 — Stockholders’ Equity (Deficit)

During 2009, the Company issued 466,268 shares of Common Stock ($0.25 per share) and 687,500 shares of Common Stock ($0.08 per share) to investors upon their conversions of Convertible Notes.

In June, September and December 2009, the Company issued 625,000, 300,000 and 625,000, respectively, of restricted shares of our common stock at $0.12, $0.10 and $0.06 per share, respectively, to a consultant pursuant to their consulting agreement and directors. For all of these restricted common stock grants, each individual issued promissory notes to the Company in exchange for their stock purchases. See the share-based footnote for further details.

In August 2009, the Company issued 357,778 shares of Common Stock ($0.13 per share) to the holders of two separate warrants under the Net Issuance clause of the warrant agreements.

In February 2010, the Company issued 150,000 restricted shares of our common stock at $0.10 per share to our newly elected director. The director issued promissory note to the Company in exchange for the stock purchases similar to the restricted share grants to all other directors. See the share-based footnote for further details.

Net Loss per Common Share — The Company calculates basic loss per share (“EPS”) and diluted EPS. EPS is computed as net loss divided by the weighted average number of common shares outstanding for the period. Diluted EPS would reflect the potential dilution that could occur from common shares issuable through stock options, warrants and other convertible securities. As of March 31, 2010 and 2009, the Company had options, warrants and other convertible securities to purchase an aggregate of approximately 39,000,000 and 21,400,000 shares of our common stock, respectively, that were excluded from the calculation of diluted loss per share as their effects would have been anti-dilutive. Therefore, the Company only presents basic loss per share on the face of the statement of operations.

Note 8 — Related Party Transactions

The Company had a $72,103 advance from one of its board of director members at December 31, 2006 evidenced by a promissory note that accrued interest at 9.5% per annum. The promissory note also contained an option to acquire 5% of the outstanding capital stock of SRS Energy at a price of $250,000. In April 2007, the indebtedness under the promissory note was repaid and the promissory note was cancelled. Under its terms, the right to exercise the option to purchase shares survived after the repayment of the indebtedness under the note. As part of the merger consideration issued by the Company pursuant to the acquisition of SRS Energy, the Company issued a warrant exercisable until August 31, 2009 to purchase 1,923,495 shares of its common stock at $0.13 per share to replace the option included in the promissory note on substantially similar terms as the option. In August 2009, this warrant was exercised under the Net Issuance clause of the warrant agreement resulting in 178,889 shares being issued.

In September 2009 and February 2010, the Company entered into stock purchase agreements with certain members of the Board of Directors. The directors issued notes to the Company in exchange for their stock purchases. See Share-Based Payments footnote for further discussion. These notes and accumulated interest are recorded as notes receivable in Stockholders’ Deficit.

The Company had engaged the law firm of Sauerwein, Simon and Blanchard (“SSB”) related to various issues including our reverse merger, our SB-2 registration statement, litigation matters and general business activity. A member of our board of directors is a partner of SSB. Since December 31, 2008, we incurred less than $100 in legal fees with SSB. As of March 31, 2010, all amounts have been paid to SSB except for approximately $90,000.

The Company uses the Crane Agency (“Crane”) as its broker for business and property insurance. Our CEO’s brother is employed by Crane and was involved in the negotiation of coverage and premiums related to policies. For the three months ended March 31, 2010 and 2009, the Company paid less than $3,000 and $3,000, respectively, in commissions on policies placed by Crane.

Beginning in 2009, the Company has provided advances to two employees — Ed Hennessey and Mike Kime. As of March 31, 2010 and 2009, the aggregate balance of advances totaled approximately $30,000 and $200, respectively. The balance is included in Prepaids and Other Current Assets on the Balance Sheet.

Two members of our Board of Directors, Dr. Jackson Nickerson and Mr. Jose Bared, Sr. are parties in investments made in our convertible note offerings. As of March 31, 2010, the aggregate amount due on these investments, including interest, is approximately $580,000.

Note 9 — Share-based Payments

In January 2010, the Company granted options under the 2007 Stock Option Plan to purchase an aggregate 120,000 shares of Common Stock to a consultant that vested immediately, with an exercise price of $0.07 per share. In February 2010, the Company issued 150,000 shares of restricted Common Stock to our new director, Jose Bared, Sr. Under the agreement Mr. Bared agreed to purchase 150,000 shares of restricted Common Stock of the Company at a cost of $0.10 per share. Mr. Bared issued a promissory note to the Company in exchange for the stock purchase. The shares purchased under the agreement are restricted shares subject to a right, but not obligation, of repurchase by the Company. The Company may exercise its repurchase right only during the 60 day period following a director’s termination of service on the Board of Directors. Commencing on February 28, 2010, the Company’s repurchase rights lapse at the rate of 8,333 shares per month of continuous service by each director through January 31, 2011, when the Company’s repurchase rights lapse on 4,167 shares per month of continuous board service until the repurchase rights have lapsed on all restricted shares. At March 31, 2010, 316,666 shares remain subject to a right of repurchase on all outstanding restricted stock grants to our directors. Additionally, the Company granted options under the Stock Plan to purchase 40,000 shares of Common Stock to Mr. Bared, with an exercise price of $0.10, that vest ratably over two years. No outstanding options were cancelled or expired as of March 31, 2010. As of March 31, 2010, 120,000 of these options were vested.

The Company has recorded stock-based compensation expense of $41,457 and $83,291 for the three months ended March 31, 2010 and 2009, respectively, for the issued stock option grants. Related to these grants, the Company will record future compensation expense of approximately $84,000 for the remaining nine months of 2010. The potential tax benefit realizable for the anticipated tax deductions of the exercise of share-based payment arrangements totaled approximately $260,000 and $240,000 at March 31, 2010 and December 31, 2009, respectively. However, due to the uncertainty that the tax benefits will be realized, these potential benefits were not recognized currently.

As of March 31, 2010, there was approximately $115,000 of unrecognized compensation cost related to all share-based payment arrangements, which will be recognized over a remaining period of approximately 2 years. There are 3,103,332 options granted that are not yet vested as of March 31, 2010. These options have a weighted average exercise price of $0.19.

Note 10 — Commitments and Contingencies

Jordan Altabet litigation — On November 11, 2009, Jordan Altabet (“Altabet”) filed suit in United States District Court in Las Vegas, Nevada alleging that Ed Hennessey (“Hennessey”) entered into a verbal agreement to sell Altabet 222,222 shares of our Common Stock, owned personally by Hennessey, for a total purchase price of $50,000. Altabet further alleges that Hennessey subsequently failed to complete the sale of shares to him and that the failure to sell shares to him caused damages in an unspecified amount. Altabet named Cleantech Biofuels, Inc. in the lawsuit also alleging that Hennessey was acting as an agent and principal of Cleantech Biofuels, Inc. at the time Hennessey allegedly entered into the verbal agreement. Hennessey denies that he and Altabet entered into any agreement of any type. We believe that this is a nuisance lawsuit filed to attempt to extract a settlement offer. Cleantech Biofuels, Inc. and Hennessey have filed a motion to dismiss this lawsuit for lack of jurisdiction and venue. If the lawsuit is permitted to continue, Cleantech Biofuels, Inc. and Hennessey intend to vigorously defend against these claims and assert all defenses available. It is not possible at this time to reasonably assess the outcome of this lawsuit or the potential impact on the Company.

Leases — The Company entered into a lease on October 16, 2007 (and took occupancy in January 2008) to rent approximately 1,800 square feet of office space for use as our corporate office, located at 7386 Pershing Ave. in St. Louis, Missouri for a term of three years. Our monthly rent under the lease is $1,800 plus the cost of utilities. We entered into a lease for office furniture in January 2008. The lease payments are approximately $450 per month for 36 months. This lease is accounted for as a capital lease for accounting purposes.

Note 11 — Subsequent Events

Beginning in April 2009, the Company commenced a second offering of units comprised of a convertible promissory note and a warrant. As of May 12, 2010, the Company has received $1,073,500 in investment proceeds. Each convertible promissory note carries a one-year term and a 6% interest rate. In addition, each note can be converted into shares of Common Stock at $0.08 per share, at the Note holder’s option. Each note was issued with a warrant to purchase additional shares of Common Stock to provide 100% coverage of the Note at a price of $0.30 per share. Under the first offering of units comprised of a convertible promissory note and warrants, which is now closed, the Company received $642,000 in investment proceeds.

The remaining Series A Convertible Debentures matured on April 16, 2010. In accordance with the Debenture agreement, the Company is in the process of converting these Debentures into shares of our common stock resulting in 2,069,375 shares to be issued to the Debenture holder.

Certain promissory notes in our second offering of units comprised of a convertible promissory note and a warrant (notes convertible at $0.08 per share) came due in April and May 2010. These promissory notes totaling $225,000 (including approximately $15,000 of accrued interest through May 12, 2010), have not yet been repaid or converted to shares of our common stock. We plan to work with each noteholder to extend the terms of, or convert, these promissory notes. There can be no assurance that we will reach agreements with any or all of these noteholders and we may be required to repay such amounts.

On May 11, 2010, we reached a settlement agreement with RAM Resources, LLC whereby they will release all claims relating to their previously filed lawsuit on November 6, 2008, in exchange for the issuance of a $40,000 Convertible Note under our second offering of units comprised of a convertible note and warrants, as described in our Debt Footnote.

On May 4, 2010, we entered into a joint research agreement with Ze-Gen, Inc., a developer of technology for converting biomass into a variety of fuel products and other chemical products, whereby we agreed to provide biomass to Ze-Gen, Inc. for testing in their proprietary processes.

Company Overview

The following discussion of our company overview and plan of operation should be read in conjunction with the financial statements and related notes to the financial statements included elsewhere in this report. This discussion contains forward-looking statements that relate to future events or our future financial performance. These statements involve known and unknown risks, uncertainties and other factors that may cause our actual results, levels of activity or performance to be materially different from any future results, levels of activity or performance. These risks and other factors include, among others, those listed under “Statement Regarding Forward-Looking Information.”

We are a development stage company focused on being a provider of: (i) cellulosic biomass derived from municipal solid waste, also known as MSW, as a feedstock for producing energy and other chemical products and (ii) recyclables (metals, plastics, glass) from the MSW.

We were originally incorporated in 1996 as Long Road Entertainment, Inc., and were formed to operate as a holding company for businesses in the theater, motion picture and entertainment industries. We ceased conducting that business in 2005 and were dormant until the fall of 2006, at which time our founder and then controlling stockholder decided to pursue the sale of the company. In anticipation of that sale, we changed our name to Alternative Ethanol Technologies, Inc.

On March 27, 2007, we entered into an Agreement and Plan of Merger and Reorganization in which we agreed to acquire SRS Energy, Inc., a Delaware corporation that is the holder of the technology licenses. Pursuant to the merger agreement, SRS Acquisition Sub, our wholly-owned subsidiary, merged into SRS Energy with SRS Energy as the surviving corporation. We consummated the merger on May 31, 2007 resulting in SRS Energy becoming our wholly-owned subsidiary. Effective August 2, 2007, we changed our name to CleanTech Biofuels, Inc.

SRS Energy was originally formed as a wholly-owned subsidiary of Supercritical Recovery Systems, Inc., a Delaware corporation, in July 2004. At that time, Supercritical Recovery Systems, Inc. was a licensee of various technologies for the processing of waste materials into usable products. Prior to our acquisition of SRS Energy, Supercritical Recovery Systems, Inc. distributed approximately 80% of its ownership of SRS Energy to the stockholders of Supercritical Recovery Systems, Inc. Since our acquisition of SRS Energy, Supercritical Recovery Systems, Inc. has ceased its business activities with respect to licensing other technologies.

In September 2008, we acquired the exclusive rights to use the Biomass Recovery System developed by Anthony Noll that we refer to as our Biomass Recovery Process in the United States and Canada. Our rights to use the Biomass Recovery Process technology permit us to use the biomass we derive from MSW to produce all energy products. In addition, in October 2008, we acquired the patent for the pressurized steam classification (“PSC”) technology from World Waste Technologies (“WWT”), who previously had purchased the patent from the University of Alabama Huntsville. As a result we became the licensor of the PSC technology to Bio-Products International, Inc. (“Bio-Products”) under its Master License Agreement. Bio-Products was the sublicensor of the PSC technology to us.

Since early 2008, we had been in litigation against Bio-Products regarding our use of the PSC technology. In March 2009, we entered into a Settlement Agreement with Bio-Products settling all claims. Pursuant to the Settlement Agreement, in addition to a customary mutual release, Bio-Products entered into a covenant not to sue whereby Bio-Products and its related parties agreed to permit us to use the Biomass Recovery Process technology worldwide, for any product that we desire and with no royalty due to Bio-Products. We also terminated our License Agreement with Bio-Products and have no further obligations thereunder. We continue to be the licensor to Bio-Products under the Master License Agreement and we continue to own the patent for the PSC technology. As a result of the Settlement Agreement, we are now capable of using the Biomass Recovery Process technology to produce any energy product that we desire and are no longer limited to production of fuel grade ethanol in the United States.

We have no operating history as a producer of biomass feedstocks or any energy products and have not constructed any operating plants to date. We have not earned any revenues to date and expect that our current capital and other existing resources will no longer be sufficient to fund the testing of our technologies or our required working capital. We will require substantial additional capital to implement our business plan and we may be unable to obtain the immediate capital required to continue operating.

Recent Developments

Beginning in April 2009, the Company commenced a second offering of units comprised of a convertible promissory note and a warrant. As of May 12, 2010, the Company has received $1,073,500 in investment proceeds. Each convertible promissory note carries a one-year term and a 6% interest rate. In addition, each note can be converted into shares of the Company’s common stock, par value $0.001 per share (the “Common Stock”), at $0.08 per share, at the Note holder’s option. Each note was issued with a warrant to purchase additional shares of Common Stock to provide 100% coverage of the Note at a price of $0.30 per share. Under the first offering of units comprised of a convertible promissory note and warrants, which is now closed, the Company received $642,000 in investment proceeds.

On May 4, 2010, we entered into a joint research agreement with Ze-Gen, Inc., a developer of technology for converting biomass into a variety of fuel products and other chemical products, whereby we agreed to provide biomass to Ze-Gen, Inc. for testing in their proprietary processes.

Plan of Operation

Our focus has shifted primarily to securing additional capital immediately. We currently do not have sufficient capital to continue operations. All of the projects described below require a significant amount of capital that we currently do not have. While we continue to aggressively pursue capital, we have not had recent success securing meaningful amounts of financing. As a result, we can provide no assurance that we will secure any capital in the immediate time frame required and the failure to do so will likely result in an inability to continue operations.

The following discussion of our plan of operation should be read in conjunction with the financial statements and related notes to the financial statements included elsewhere in this report. This discussion contains forward-looking statements that relate to future events or our future financial performance. These statements involve known and unknown risks, uncertainties and other factors that may cause our actual results, levels of activity or performance to be materially different from any future results, levels of activity or performance. These risks and other factors include, among others, those listed under “Statement Regarding Forward-Looking Information.”

Our company was initially conceived as a fully-integrated producer of cellulosic ethanol using the PSC technology for cleaning and separating municipal solid waste, also known as MSW, into its component parts, and a dilute acid hydrolysis technology developed by Brelsford Engineering, Inc. To further enhance our ability to produce ethanol, in 2008 we licensed a technology that uses nitric acid to hydrolyze biomass into ethanol. The technology developed at the University of California Berkeley is controlled by HFTA, Inc. pursuant to a Master License Agreement with the University of California Berkeley and was sublicensed to us for the production of ethanol from MSW.

Based on our investigation and acquisition of new technologies and research and development of our existing technologies in 2008, we re-focused our business to the commercialization of our Biomass Recovery Process technology for cleaning and separating MSW into its component parts through the acquisition of further technology to clean and separate MSW, and set about to consolidate the ownership and/or rights to use intellectual property around this technology. The technology is currently in use by another operator in a commercial setting in Australia. As a result, we believe this technology is ready for commercial implementation in the United States and elsewhere. In furtherance of our new focus, we have begun evaluating potential commercial projects using our technology.

As a result of our new focus on converting MSW into a biomass feedstock for energy or chemical products, we determined that we no longer would use the Brelsford and HFTA technologies. In the fourth quarter of 2008, Brelsford Engineering, Inc. terminated our license to the Brelsford technology for non-payment of certain fees. We decided not to use the technology going forward in our operations and wrote off the remaining asset as of December 31, 2008. The impairment loss of $97,500 is included in research and development expense on the statement of operations for the year ended December 31, 2008. Additionally, we terminated our agreement with HFTA, Inc. during the fourth quarter of 2009 as we determined to not use the HFTA technology going forward in our operations. We wrote off the related asset of approximately $693,000 as an impairment loss and the loss is included in research and development expense on the statement of operations for the year ended December 31, 2009.

Biomass Feedstock Production

We are seeking to develop a plant in a major metropolitan area. We are currently working with existing waste haulers to develop one or more waste transfer stations where waste collected will be processed using our technology and the biomass produced used to create heat and/or power.

We are seeking to implement our technology in Maryville, Missouri. The biomass we produce will be supplied to Northwest Missouri State University for research purposes in advanced biofuel technologies and to supply steam for the University. The University has used biomass to produce steam for more than twenty years and has significant experience in handling biomass feedstocks.

We have been selected by the County Commission and Public Works Authority of Pawnee County, Oklahoma for implementation at a proposed recycling and biomass recovery facility to be constructed in Pawnee County. The Pawnee County Commission and the Pawnee Public Works Authority have both adopted resolutions to pursue the possibility of bringing the Biomass Recovery Process to an existing quarry site in Pawnee County. The Pawnee Public Works Authority has engaged an engineering consultant to begin the project’s technology evaluation and site selection. The consultant will work to design the initial system for the facility and determine its ultimate cost. The consultant and the County will also work on obtaining grants and permits as well as all other aspects of getting the project funded and started. This project is in the preliminary planning stage. No assurance can be given that it will proceed as planned, or at all.

We have completed construction of a small test vessel in Kentucky. Beginning in April 2009, this vessel has processed approximately 12 tons of MSW into approximately 4-5 tons of biomass. We are providing the biomass produced during this testing phase to a variety of fuel producers who are evaluating the biomass we produce from MSW as a feedstock for their technologies. In addition to the developments we are currently contemplating, other development opportunities have been presented to us and we are currently evaluating those potential developments. Also, a variety of federal, state and local stimulus funds, grant opportunities, loan guarantees and other programs have recently been announced or are expected to be announced in the near-term that may lead to a variety of new development opportunities for the Company. On October 15, 2009, we filed final applications for Section 48C with respect to our proposed developments. In January 2010, we were informed that these projects were not selected for funding. We anticipate filing additional grant and loan applications for governmental assistance in the near-term future. Upon operating a plant and after refining our know-how with respect to implementation of the technology, we intend to seek to partner with waste haulers, landfill owners and municipalities to implement the technology across the United States and internationally.

The further implementation of the licensing of our technology and/or the development of commercial plants described above will require significant additional capital, which we currently do not have. We cannot provide any assurance that we will be able to raise this additional capital. While we anticipate that financing for these projects could be provided in large part via tax exempt bond financing or through the use of loan guarantees from local, state and federal authorities, we have not secured any of such financing and there can be no assurance that we will be able to secure any such financing.

Diesel Fuel Production

We previously anticipated completing an agreement with Green Power, Inc. (“Green Power”) to provide biomass for testing at Green Power’s facility and if that proves successful, to build a 200 ton per day MSW processing station to provide biomass for an existing 100 ton per day diesel fuel production plant. To date we have not been able to reach an agreement as to the nature and amount of biomass to be produced or other key terms of this relationship that are required for us to proceed. These issues and a number of other items will be required to be resolved before we are able to complete any agreement with Green Power. We have not completed an agreement to date and there can be no assurance that we will complete any agreement and proceed with this development.

Bio-Fuel and Bio-Chemical Joint Testing/Research

As soon as we are able to process MSW into biomass through our test vessel in Kentucky and/or in future commercial vessels, we plan to enter into joint research agreements with companies looking to process biomass in their system(s) for various types of energy and chemical production. This testing and research will provide possible revenue streams, projects and additional opportunities for use of our biomass.

In July 2009, we entered into a joint research agreement with Fiberight, LLC (“Fiberight”) to establish the anticipated yields and operating costs from using biomass produced by us for the production of ethanol using Fiberight’s proprietary enzymatic processes. Under the agreement, we provided approximately one ton of biomass feedstock derived from MSW from the City of Chicago to use in Fiberight’s conversion technology.

In August 2009, we entered into a joint research agreement with GeoSyn Fuels, L.L.C. (“GeoSyn”) whereby we agreed to provide GeoSyn with biomass feedstock derived from MSW from the City of Chicago for GeoSyn’s testing of their proprietary process for converting biomass into ethanol and other products.

In May 2010, we entered into a joint research agreement with Ze-Gen, Inc., a developer of technology for converting biomass into a variety of fuel products and other chemical products, whereby we agreed to provide biomass to Ze-Gen, Inc. for testing in their proprietary processes.

New Technologies; Commercializing Existing Technologies

Because of our unique ability to produce a clean, homogenous biomass feedstock, we are frequently presented with the opportunity to partner with or acquire new technologies. In addition to developing our current technologies, we will continue to add technologies to our suite of solutions that complement our core operations. We believe that our current technologies and aspects of those in development will enable us to eventually expand our business to use organic material from other waste streams such as municipal bio-solids from waste water facilities and animal waste for fuel production.

To commercialize our technology, we intend to:

•

license and/or construct and operate a commercial plant that: (i) processes MSW into cellulosic biomass for conversion into energy or chemical products and (ii) separates recyclables (metals, plastics, glass) for single-stream recycling;

•

identify and partner with landfill owners, waste haulers and municipalities to identify locations suitable for our technology; and

•

pursue additional opportunities to implement our technology in commercial settings at transfer stations and landfills in the United States and elsewhere in the world.

Our ability to implement this strategy will depend on our ability to raise significant amounts of additional capital and to hire appropriate managers and staff. Our success will also depend on a variety of market forces and other developments beyond our control.

Results of Operations

The following tables set forth the amounts of expenses and changes represented by certain items reflected in our consolidated statements of operations for the three months ended March 31, 2010 and 2009:

		Three months ended
		March 31, 2010				March 31, 2009				Change
General and administrative		$	195,401			$	243,823			$	(48,422	)
Professional fees			41,524				109,413				(67,889	)
Research and development			—				101				(101	)
Operating loss			236,925				353,337				(116,412	)
Other expense (income):
Interest expense			119,518				226,127				(106,609	)
Other income			—				(4,667	)			4,667
Interest income			(4,291	)			(2,241	)			(2,050	)
Net loss applicable to common stockholders		$	352,152			$	572,556			$	(220,404	)

General and administrative — The decrease in expense in 2009 is due primarily to a reduction in expense of approximately $42,000 in share-based compensation expense.

Professional Fees — The decrease in 2009 is due primarily to a reduction in legal fees of approximately $48,000.

Interest expense — The decrease in 2009 is due primarily to a reduction in the amortization of discounts related to various notes of approximately $115,000. These notes mature in one year and were issued from October 2008 through March 2010 and thus some discounts have been fully expensed.

Liquidity and Capital Resources

As a development-stage company, we have no revenues and will be required to raise additional capital to continue operations, execute our business plan and commercialize our products. Beginning in September 2008 and as of May 12, 2010, we raised an aggregate of $1,715,500, in separate note issuances from investors in exchange for units comprised of a convertible note and warrants. We are continuing to explore opportunities to raise cash through the issuance of these units and other financing opportunities. As of May 12, 2010, our current cash is not sufficient to fund our operations. Our liabilities are substantially greater than our current available funds. We are seeking additional financing through the sale of additional equity, various government funding opportunities and/or possibly through strategic alliances with larger energy or waste management companies. However, we may not be successful in securing additional capital. If we are not able to obtain additional financing in the immediate future, we will be required to delay our development until such financing becomes available and may be required to cease operations. Further, even assuming that we secure additional funds, we may never achieve profitability or positive cash flow. If we are not able to timely and successfully raise additional capital and/or achieve profitability or positive cash flow, we will not have sufficient capital resources to implement our business plan or to continue our operations.

Debt

Convertible Notes Payable

During September 2008, the Company commenced an offering of units comprised of a convertible promissory note and a warrant. The Company raised a total of $642,000 of investment proceeds through March 31, 2009 and this offering is closed. As of March 31, 2010, all of these notes have either been converted to shares of our common stock or re-priced to our second convertible note offering (resulting in new notes with a total face value of $539,829, which included the original principal and interest through the date of re-pricing). Each convertible promissory note carried a one-year term and a 6% interest rate. In addition, each note could have been converted, at the note holder’s option, at any time during the one-year term into shares of Common Stock at $0.25 per share, or prior to the closing of any Qualifying Equity Financing (minimum capital received of $5 million). Each note was issued with a warrant to purchase additional shares of Common Stock equal to the principal amount of the promissory note at a price of $0.45 per share. These promissory notes had been recorded as short-term debt (notes payable) in the financial statements, net of discounts for the conversion and warrant features. The discounts were being amortized on a straight-line basis over the term of each note and are fully expensed as of March 31, 2010. For the three months ended March 31, 2010 and 2009, amortization of approximately $7,000 and $150,000, respectively, for these discounts has been recorded in interest expense. All warrants related to this offering of units remain outstanding at the original pricing.

During April 2009, the Company commenced a second offering of units comprised of a convertible promissory note and warrants. As of March 31, 2010, the Company raised a total of $1,063,500 of investment proceeds. One note was converted during 2009 leaving $1,038,500 face value of notes outstanding. Each convertible promissory note carries a one-year term and a 6% interest rate. In addition, each note can be converted, at the note holder’s option, at any time during the one-year term into shares of the Company’s Common Stock, at $0.08 per share, or prior to the closing of any Qualifying Equity Financing (minimum capital received of $5 million). Each note was issued with a warrant to purchase additional shares of Common Stock to provide 100% coverage of the promissory note at a price of $0.30 per share. These promissory notes have been recorded as short-term debt (notes payable) in the financial statements, net of discounts for the conversion and warrant features. The discounts are being amortized on a straight-line basis over the term of each note. For the three months ended March 31, 2010, amortization of approximately $79,000 and $0, respectively, for these discounts has been recorded in interest expense.

Vertex (formerly WWT) Note Payable

On October 22, 2008, the Company completed the purchase of Patent No. 6,306,248 (the “Patent”) pursuant to a Patent Purchase Agreement (“Agreement”) with World Waste Technologies, Inc. (“WWT”). The Patent is the basis for the pressurized steam classification technology that cleans and separates municipal solid waste into its component parts, which the Company had licensed from Bio-Products International, Inc. Pursuant to the Agreement, the Company issued to WWT a note in the amount of $450,000 and a warrant to purchase 900,000 shares of Common Stock at a price of $0.45 per share and warrants to purchase an additional 900,000 shares of Common Stock at a price of $0.45 per share contingent on payment of the note by July 22, 2009 (the original maturity date). WWT assigned all of its rights, title and interest in the note, warrants, security agreement and purchase agreement to Vertex Energy, Inc. as a result of a merger in March 2009. We entered into amendments dated July 23, 2009 whereby: (i) the Company paid 10% of the original note and all accrued interest to date, (ii) all previous warrants (totaling 1,800,000 shares) were reissued at a price of $0.11 per share with no contingencies and (iii) the remaining payments on the note were scheduled to be paid on October 22, 2009 (50% of principal plus accrued interest to date not yet paid) and January 22, 2010 (remaining principal and accrued interest to date). We entered into amendments dated October 22, 2009 whereby: (i) the October 22, 2009 payment was deferred until November 22, 2009 and (ii) we issued additional warrants to Vertex for 500,000 shares of Common Stock at a price of $0.10 per share. The warrants are exercisable at any time for five years from the date of issuance or reissuance. The value of these warrants has been recorded as a contra-balance amount discount with the note and is being amortized through interest expense over the life of the note. For the three months ended March 31, 2010, amortization of approximately $7,000 and $58,000 for this discount has been recorded in interest expense. As of May 12, 2010, all payments have been made except for approximately $185,000 in principal and interest. Final payment on this note was due January 22, 2010.

Series A Convertible Debentures

In April 2007, the Company sold $1,400,000 of Series A Convertible Debentures (“Debentures”), due April 16, 2010, that convert into shares of the Company’s Common Stock at $0.15 per share. The Company filed a registration statement with regard to the sale of these shares of Common Stock, which was declared effective by the Securities and Exchange Commission on January 2, 2008. The debentures accrue interest at 6% per annum. The interest is payable in cash or shares of the Company’s Common Stock at the Company’s option.

During March 2008, various debenture holders converted an aggregate amount of $630,000 of our Debentures, plus interest earned, into 4,433,067 shares of Common Stock. During April 2008, various debenture holders converted an aggregate amount of $630,000 of our Debentures, plus interest earned, into 4,455,844 shares of Common Stock. These transactions converted in the aggregate $1,260,000 of our Debentures, leaving $140,000 remaining to be converted. As of April 16, 2010, the remaining $140,000 outstanding on our Debentures matured and is in the process of being converted to 2,069,375 shares of our common stock.

Off-Balance Sheet Arrangements

We have no off-balance sheet arrangements.

Critical Accounting Policies

We prepare our consolidated financial statements in accordance with accounting principles generally accepted in the United States of America. Certain accounting issues require management estimates and judgments for the preparation of financial statements. Our management periodically evaluates the estimates and judgments made. Management bases its estimates and judgments on historical experience and on various factors that are believed to be reasonable under the circumstances. Actual results may differ from these estimates as a result of different assumptions or conditions.

We believe that the estimates, assumptions and judgments relating to long-lived assets, convertible notes and warrants, fair-value measurement, share-based compensation and income tax matters have the greatest potential impact on our financial statements. Therefore, we consider these to be our critical accounting estimates. Our critical accounting policies and estimates are more fully described in our annual report on Form 10-K for the year ended December 31, 2009, filed with the Securities and Exchange Commission on March 30, 2010. Our critical accounting policies and estimate assumptions have not changed during the three months ended March 31, 2010.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

Not applicable.

Item 4T. Controls and Procedures

Effectiveness of Disclosure Controls and Procedures — We maintain a set of disclosure controls and procedures designed to ensure that information required to be disclosed in our reports filed under the Securities Exchange Act of 1934, as amended, is recorded, processed, summarized and reported within the time periods specified by the Security and Exchange Commission’s rules and regulations. Disclosure controls are also designed with the objective of ensuring that this information is accumulated and communicated to our management, including our chief executive officer and chief financial officer, as appropriate, to allow timely decisions regarding required disclosure.

Our management does not expect that our disclosure controls and procedures will necessarily prevent all fraud and material error. Our disclosure controls and procedures are designed to provide reasonable assurance of achieving the objectives outlined above. Based on their most recent evaluation, our chief executive officer and chief financial officer concluded that our disclosure controls and procedures are effective at that reasonable assurance level at March 31, 2010. Further, the design of a control system must reflect the fact that there are resource constraints, including, but not limited to having three total employees (chief executive officer, general counsel and chief financial officer), and the benefits of controls must be considered relative to their costs. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, within the Company have been detected. These inherent limitations include the realities that judgments in decision-making can be faulty, and that breakdowns can occur because of simple error or mistake.

Changes in Internal Control Over Financial Reporting — During the three months ended March 31, 2010, there were no material changes in the Company’s internal control over financial reporting that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.

PART II. OTHER INFORMATION

Item 1. Legal Proceedings

Ram Resources, L.L.C. v. CleanTech Biofuels, Inc. On May 11, 2010, we reached a Settlement Agreement with RAM Resources, LLC whereby they will release all claims relating to their previously filed lawsuit on November 6, 2008, in exchange for the issuance of a $40,000 Convertible Note under our second offering of units comprised of a convertible note and warrants, as described in our Debt Footnote.

Jordan Altabet v. Ed Hennessey and CleanTech Biofuels, Inc. On November 11, 2009, Jordan Altabet (“Altabet”) filed suit in United States District Court in Las Vegas, Nevada alleging that Ed Hennessey (“Hennessey”) entered into a verbal agreement to sell Altabet 222,222 shares of our Common Stock, owned personally by Hennessey, for a total purchase price of $50,000. Altabet further alleges that Hennessey subsequently failed to complete the sale of shares to him and that the failure to sell shares to him caused damages in an unspecified amount. Altabet named CleanTech in the lawsuit also alleging that Hennessey was acting as an agent and principal of CleanTech Biofuels, Inc. at the time Hennessey allegedly entered into the verbal agreement. Hennessey denies that he and Altabet entered into any agreement of any type. We believe that this is a nuisance lawsuit filed to attempt to extract a settlement offer. CleanTech Biofuels, Inc. and Hennessey have filed a motion to dismiss this lawsuit for lack of jurisdiction and venue. If the lawsuit is permitted to continue, CleanTech Biofuels, Inc. and Hennessey intend to vigorously defend against these claims and assert all defenses available.

Item 1A. Risk Factors

In addition to the other information set forth in this report and below in this Item, you should carefully consider the risk factors discussed in Part I, Item 1A in our Annual Report on Form 10-K for the year ended December 31, 2009, which could materially affect our business, financial condition or future results. These cautionary statements are to be used as a reference in connection with any forward-looking statements. The factors, risks and uncertainties identified in these cautionary statements are in addition to those contained in any other cautionary statements, written or oral, which may be made or otherwise addressed in connection with a forward-looking statement or contained in any of our subsequent filings with the Securities and Exchange Commission.

We do not currently have enough cash to fund our operations. If we are not able to obtain additional financing in the immediate future, we will be required to delay our development until such financing becomes available and may be required to cease operations.

Item 2. Unregistered Sales of Equity Securities and Use of Proceeds —

During April 2009, the Company commenced a second offering of units comprised of a convertible promissory note and a warrant. As of March 31, 2010, the Company raised a total of $1,063,500 of investment proceeds. Each convertible promissory note carries a one-year term and a 6% interest rate. In addition, each note can be converted into shares of the Company’s common stock, par value $0.001 per share (the “Common Stock”), at $0.08 per share at the holder’s option. Each note was issued with a warrant to purchase additional shares of Common Stock to provide 100% coverage of the principal amount of the associated note at a price of $0.30 per share. One note was converted during 2009 leaving $1,038,500 face value of notes outstanding. The issuance of units and the issuance of Common Stock upon conversion of notes were exempt from the registration requirements of the Securities Act of 1933, as amended (the “Securities Act”), pursuant to Rule 506 of Regulation D promulgated under the Securities Act (“Rule 506”) and/or Section 4(2) of the Securities Act.

In January 2010, the Company awarded stock options to a consultant representing the right to acquire 120,000 shares of Common Stock at an exercise price of $0.07 per share. The award of stock options was exempt from the registration requirements of the Securities Act pursuant to Rule 701 promulgated under the Securities Act.

In February 2010, the Company issued to its new director 150,000 restricted shares of Common Stock at a price of $0.10 per share and awarded a stock option representing the right to acquire 40,000 shares of Common Stock at an exercise price of $0.10 per share. The director issued a promissory note to the Company in exchange for the restricted Common Stock purchase. The award of stock options and the issuance of restricted stock to our director were exempt from the registration requirements of the Securities Act pursuant to Rule 701 promulgated under the Securities Act.

Item 3. Defaults Upon Senior Securities — Certain promissory notes in our second offering of units comprised of a convertible promissory note and a warrant (notes convertible at $0.08 per share) came due in April and May 2010. These promissory notes totaling approximately $225,000 (including approximately $15,000 of accrued interest through May 14, 2010), have not yet been repaid or converted to shares of our common stock. We plan to work with each noteholder to extend the terms of, or convert, these promissory notes. There can be no assurance that we will reach agreements with any or all of these noteholders and we may be required to repay such amounts.

Item 4. Submission of Matters to a Vote of Security Holders — None.

Item 5. Other Information — On October 22, 2008, the Company completed the purchase of Patent No. 6,306,248 (the “Patent”) pursuant to a Patent Purchase Agreement (“Agreement”) with World Waste Technologies, Inc. (“WWT”). The Patent is the basis for the pressurized steam classification technology that cleans and separates municipal solid waste into its component parts, which the Company had licensed from Bio-Products International, Inc. Pursuant to the Agreement, the Company issued to WWT a note in the amount of $450,000 and a warrant to purchase 900,000 shares of Common Stock at a price of $0.45 per share and warrants to purchase an additional 900,000 shares of Common Stock at a price of $0.45 per share contingent on payment of the note by July 22, 2009 (the original maturity date). WWT assigned all of its rights, title and interest in the note, warrants, security agreement and purchase agreement to Vertex Energy, Inc. (“Vertex”) as a result of a merger in March 2009. We entered into amendments dated July 23, 2009 whereby: (i) the Company paid 10% of the original note and all accrued interest to date, (ii) all previous warrants (totaling 1,800,000 shares) were reissued at a price of $0.11 per share with no contingencies and (iii) the remaining payments on the note were scheduled to be paid on October 22, 2009 (50% of principal plus accrued interest to date not yet paid) and January 22, 2010 (remaining principal and accrued interest to date). We entered into amendments dated October 22, 2009 whereby: (i) the October 22, 2009 payment was deferred until November 22, 2009 and (ii) we issued additional warrants to Vertex for 500,000 shares of Common Stock at a price of $0.10 per share. As of May 12, 2010, all payments have been made except for approximately $185,000 in principal and interest. Final payment on this note was due January 22, 2010.
