NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (unaudited)

Note 1 – Organization and Business

Alternative Ethanol Technologies, Inc. (the “Company”), was incorporated in Delaware on December 20, 1996. Effective August 2, 2007, the Company changed its name to CleanTech Biofuels, Inc. Except where otherwise noted, the words “we,” “us,” “our,” and similar terms, as well as “CleanTech” or the “Company,” refer to CleanTech Biofuels, Inc. and its subsidiaries, collectively.

On March 27, 2007, the Company acquired SRS Energy, Inc., a Delaware corporation (“SRS Energy”), pursuant to an Agreement and Plan of Merger and Reorganization. In accordance with the merger agreement, SRS Acquisition Sub, Inc., a Delaware corporation and wholly-owned subsidiary of the Company, merged with and into SRS Energy. The merger was consummated on May 31, 2007 and resulted in SRS Energy becoming a wholly-owned subsidiary of the Company. As a result of the merger, the stockholders of SRS Energy surrendered all of their issued and outstanding Common Stock and received shares of the Company’s Common Stock, $.001 par value per share (“Common Stock”). The former parent of SRS Energy, Supercritical Recovery Systems, Inc., immediately prior to the merger, distributed 78.8% of its 96% ownership in SRS Energy to its shareholders on a pro rata basis. For accounting purposes, because the Company had been a public shell company prior to the merger, the merger was treated as an acquisition of the Company and a recapitalization of SRS Energy.

The Company is in its development stage and has been engaged in technology development and pre-operational activities since its formation. The Company is currently seeking outside sources of funding to design and build a commercial biomass recovery plant to provide biomass feedstock for customer evaluation and trial purchases. Initially, the biomass feedstock output is expected to be sold or provided to electric utilities, power and steam producers, and biofuel and chemical research firms for evaluation. In addition to research and development, the Company is also working towards licensing and/or developing potential commercial projects. These projects plan to focus on cleaning and separating municipal solid waste (also referred to as MSW) into its component parts in order to obtain: (i) a homogenous feedstock of cellulosic biomass for producing energy and other chemical products and (ii) recyclable products (metals, plastics, aluminum).

The Company has no operating history as a producer of biomass or energy sources and has not constructed any plants to date. We have no revenues and will be required to secure outside funding in order to execute our business plan and commercialize our products. Our current cash is not sufficient to fund our current operations. Our liabilities are substantially greater than our current available funds and current assets. Although we continue to seek 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, we have not had recent success securing meaningful amounts of financing. The Company will require substantial additional financing to implement its business plan and it may be unable to obtain the capital required to do so. If we are not able to immediately and successfully raise additional capital and/or achieve profitability or positive cash flow, we may not be able to continue operations.

The accompanying unaudited, consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States for interim financial information and with the instructions to Form 10-Q and Articles 8 and 10 of Regulation S-X. Accordingly, they do not include all of the information and notes required by generally accepted accounting principles for complete financial statements. In the opinion of management, all adjustments, consisting of normal recurring items considered necessary for a fair presentation, have been included. Operating results for the three months ended March 31, 2019 are not necessarily indicative of the results that may be expected for the year ended December 31, 2019. For further information, refer to the Company’s audited Consolidated financial statements and notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2018, filed with the Securities and Exchange Commission (“SEC”) on April 1, 2019.

Note 2 – Recent Accounting Pronouncements

In August 2018, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2018-13, "Fair Value Measurement (Topic 820): Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement." ASU 2018-13 modified the disclosure requirements in Topic 820, "Fair Value Measurement," based on the FASB Concepts Statement, "Conceptual Framework for Financial Reporting - Chapter 8: Notes to Financial Statements," including consideration of costs and benefits. The guidance is effective for fiscal years beginning after December 15, 2019 and for interim periods within those fiscal years, with early adoption permitted. The Company is currently evaluating the potential effects of this guidance on its consolidated financial statements.

In June 2018, the FASB issued ASU No. 2018-07, “Compensation – Stock Compensation (Topic 718).” This ASU addresses share-based payment transactions for acquiring goods and services from nonemployees. An entity should apply the requirements of Topic 718 to nonemployee awards except for specific guidance on inputs to an option pricing model and the attribution of cost (that is, the period of time over which share-based payment awards vest and the pattern of cost recognition over that period). The amendments specify that Topic 718 applies to all share-based payment transactions in which a grantor acquires goods or services to be used or consumed in a grantor’s own operations by issuing share-based payment awards. The amendments also clarify that Topic 718 does not apply to share-based payments used to effectively provide (1) financing to the issuer or (2) awards granted in conjunction with selling goods or services to customers as part of a contract accounted for under Topic 606, Revenue from Contracts with Customers. The amendments in this Update are effective for public business entities for fiscal years beginning after December 15, 2018, including interim periods within that fiscal year. For all other entities, the amendments are effective for fiscal years beginning after December 15, 2019, and interim periods within fiscal years beginning after December 15, 2020. Early adoption is permitted, but no earlier than an entity’s adoption date of Topic 606. The adoption of this guidance did not have a material impact on our consolidated financial statements and related disclosures.

In July 2017, the FASB issued ASU No. 2017-11, “Earnings Per Share (Topic 260), Distinguishing Liabilities from Equity (Topic 480), Derivatives and Hedging (Topic 815).” This ASU changes the classification analysis of certain equity-linked financial instruments (or embedded features) with down round features. As a result, a freestanding equity-linked financial instrument (or embedded conversion option) no longer would be accounted for as a derivative liability at fair value as a result of the existence of a down round feature. For freestanding equity classified financial instruments, the amendments require entities that present earnings per share (“EPS”) in accordance with Topic 260 to recognize the effect of the down round feature when it is triggered. The standard is effective for annual reporting periods beginning after December 15, 2019, and interim periods within fiscal years beginning after December 15, 2020. Early adoption is permitted, including adoption in any interim period. We are currently assessing the impact the guidance will have on our consolidated financial statements and related disclosures.

In May 2017, the FASB issued ASU No. 2017-09, “Compensation – Stock Compensation (Topic 718) Scope of Modification Accounting.” This ASU, which amends the scope of modification accounting for share-based payment arrangements, provides guidance on the types of changes to the terms or conditions of share-based payment awards to which an entity would be required to apply modification accounting under ASC 718. Specifically, an entity would not apply modification accounting if the fair value, vesting conditions, and classification of the awards are the same immediately before and after the modification. The standard is effective for annual reporting periods, including interim periods within those annual reporting periods, beginning after December 15, 2017. Early adoption is permitted, including adoption in any interim period. The adoption of this guidance did not have a material impact on our consolidated financial statements and related disclosures.

In January 2017, the FASB issued ASU No. 2017-04, “Intangibles —Goodwill and Other (Topic 350) Simplifying the Test for Goodwill Impairment.” This ASU simplifies several aspects of the accounting for goodwill impairment. The guidance requires an entity to perform its annual, or interim, goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount. An entity should recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value; however, the loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. The standard is effective for annual periods beginning after December 15, 2019. Early adoption is permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. We are currently assessing the impact the guidance will have on our consolidated financial statements and related disclosures.

Table of Contents

In February 2016, the FASB issued ASU No. 2016-02, “Leases.” This ASU requires lessees to recognize most leases on their balance sheets for the rights and obligations created by those leases. The guidance requires enhanced disclosures regarding the amount, timing, and uncertainty of cash flows arising from leases and will be effective for interim and annual periods beginning after December 15, 2018. Early adoption is permitted. The ASU requires adoption based upon a modified retrospective approach. The adoption of this guidance did not have a material impact on our consolidated financial statements and related disclosures.

In May 2014, the FASB issued ASU No. 2014-09, “Revenue from Contracts with Customers.” This ASU will supersede most of the existing revenue recognition requirements in U.S. GAAP and will require entities to recognize revenue at an amount that reflects the consideration to which the Company expects to be entitled in exchange for transferring goods or services to a customer. The new standard also specifies new accounting for costs associated with obtaining or fulfilling contracts with customers and expands the required disclosures related to revenue and cash flows from contracts with customers. This new guidance is effective for annual reporting periods beginning after December 15, 2016, including interim periods within that reporting period and can be adopted either retrospectively to each prior reporting period presented or as a cumulative-effect adjustment as of the date of adoption, with early application not permitted. In August 2015, the FASB approved a one-year deferral of the effective date of this ASU. This standard became effective beginning with the first quarter 2018 and can be adopted either retrospectively to each prior reporting period presented or as a cumulative effect adjustment as of the date of adoption. We have adopted the guidance and currently it does not have a material impact on the financial statements as the Company does not have revenue. The requirements of the ASU will be followed when the Company does have revenue.

There were various other accounting standards updates recently issued, most of which represented technical corrections to the accounting literature or were applicable to specific industries and are not expected to have a material impact on the Company's financial position, results of operations or cash flows.

Note 3 – Mergers/Acquisitions

Biomass North America Licensing, Inc.

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 patented technology licensed from Biomass North America, LLC, the former parent of Biomass (the “Licensor”), to clean and separate MSW (the “Biomass Recovery Process”). In July 2010, the United States Patent and Trademark Office issued US patent number 7,745,208 for this process (the “BRP Patent”).

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% 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. In accordance with a November 2013 amendment, the Company has an exclusive license in the United States and Canada to use the Biomass Recovery Process which includes no performance requirements on the Company; the license agreement is for a term of 21 years from the date of the amendment or the life of any patent issued for the Biomass Recovery Process, including any amendments, modifications or extensions; the license requires that the Company pay a royalty in the amount of $2.00 per ton of MSW used in the Biomass Recovery Process to the Licensor; and the Company released the 4,000,000 shares of Common Stock to the Licensor previously held in escrow since the merger. The Company has recorded a long-term asset of approximately $1.6 million which it will begin to amortize upon utilizing the license in our operations.

25 Van Keuren LLC

On June 23, 2016, the Company entered into an Acquisition Agreement with 25 Van Keuren LLC, a New Jersey Limited Liability Company (“Van Keuren”), pursuant to which the Company acquired 99% of the outstanding membership interests in Van Keuren with the former members of Van Keuren retaining a 1% interest. As payment for the acquisition, the Company issued in the aggregate 1,000,000 shares of restricted Common Stock of the Company (par value $0.001) to certain holders of membership interests in Van Keuren. As of the close of business on June 23, 2016, the Company stock quote was $0.05. Van Keuren has had no operations or revenue since inception and has solely been working towards obtaining the permits required to operate a municipal solid waste transfer station and material recovery facility (“TS/MRF”). The total assets of Van Keuren at the time of the acquisition were $51,000 (2.3% of the Company’s assets). The liabilities and equity consisted of accounts payable of $27,000 and member equity of $24,000. As of August 29, 2018, the Company’s investment in Van Keuren was divested pursuant to a Settlement Agreement and Release among the Company and the former members of Van Keuren (the “Van Keuren Settlement Agreement”), and the related intangible assets were written off.

The Solid Waste Management Plan of the New Jersey Department of Environmental Protection (“DEP”), following certification of an amendment to the New Jersey Sports and Exposition Authority, includes proposed operation of a TS/MRF at a site located in Jersey City, New Jersey. CleanTech Biofuels intends to seek the necessary permits and approvals from the New Jersey DEP to build, own and operate the TS/MRF. As part of the Van Keuren Settlement Agreement, CleanTech acquired a one-year option to lease certain property in Jersey City within 30 days after the final permit issues from the New Jersey DEP, which expires on August 29, 2019. The Company intends to: (1) install its Biomass Recovery Process on the site, and (2) operate the TS/MRF. Costs incurred towards obtaining the required permits were recorded as an intangible asset on our consolidated financial statements. These costs were removed from the consolidated financial statements as a part of the divestiture of CleanTech’s interest in Van Keuren.

Note 4 – Goodwill and Intangibles

The Company’s goodwill and acquired intangible assets with indefinite lives are not amortized, but are subject to an annual impairment test. The Company performs an impairment analysis on its goodwill and intangible assets at least annually and whenever events or changes in circumstances indicate that the carrying value of such assets may not be fully recoverable. Acquired intangible assets with definite lives are amortized over their estimated useful lives and are tested for impairment only when impairment indicators are present. The Goodwill recorded was a result of the acquisition of Van Keuren in June 2016 as disclosed previously in Note 3. As of August 29, 2018, the Company’s investment in Van Keuren was divested and the related intangibles were written off.

Note 5 – Patent

The Company owns US Patent No. 6,306,248 (the “PSC Patent”), which is the underlying technology upon which the BRP Patent is based. The Company acquired the PSC Patent on October 22, 2008 pursuant to a Patent Purchase Agreement (“Agreement”) with World Waste Technologies, Inc. (“WWT”). As part of the acquisition of the PSC Patent, we also became the licensor of such technology under the existing license agreement between Bio-Products International, Inc., the licensee (“Bio-Products”) and WWT. The Company has paid WWT $600,000 and issued warrants to purchase 1,800,000 shares of Common Stock at $0.10 per share and 500,000 shares of Common Stock at $0.11 per share. 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. The warrants had an exercisable term of five years which expired on October 22, 2014. The cost of the PSC Patent acquisition of $600,000 is recorded as a long-term asset on the Balance Sheet.

On September 1, 2010, the Company issued a promissory note to CMS Acquisition, LLC (“CMS”) in the amount of $100,000 and bearing interest at 6.0% per annum. The note is secured with a security interest in the PSC Patent. In connection with the financing, the Company issued a warrant to CMS to purchase 2,000,000 shares of Common Stock at a price of $0.05 per share. The warrant is exercisable at any time for five years from the date of issuance or re-issuance. The note was originally to mature on February 28, 2011. The Company and CMS have entered into various amendments extending the due date, the most recent of which was April 26, 2017, which extended the due date to April 26, 2018. As consideration in the various amendments to this note, the Company has: (i) paid $30,000 towards accrued interest to date and principal on the note, (ii) increased the interest rate to 10% as of May 15, 2011, (iii) re-dated the original warrants to April 26, 2017, (iv) issued new warrants for 300,000 shares of Common Stock with an exercise price of $0.05 and exercisable at any time until April 26, 2022, (v) issued new warrants for 150,000 shares of Common Stock with an exercise price of $0.10 and exercisable at any time until April 26, 2022, and (vi) approved the assignment of the note by CMS to the WL Meyer Legacy Trust. For more information on this note, see Item 2 – Management’s Discussion and Analysis of Financial Condition and Results of Operations – Debt.

Note 6 – Technology Licenses

Biomass North America Licensing, Inc.

We own an exclusive license in the United States and Canada to use the Biomass Recovery Process (See Note 3 – Mergers/Acquisitions). We have recorded a long-term asset of approximately $1.6 million for the value of this license. Amortization of this asset will begin upon commencement of the use of the Biomass Recovery Process.

In accordance with a November 2013 amendment, the Company has an exclusive license in the United States and Canada to use the Biomass Recovery Process and includes no performance requirements on the Company; the license agreement is for a term of 21 years from the date of the amendment or the life of any patent issued for the Biomass Recovery Process, including any amendments, modifications or extensions; and the license requires that the Company pay a royalty in the amount of $2.00 per ton of MSW used in the Biomass Recovery Process to the Licensor.

Bio-Products International, Inc.

As disclosed in Note 5 - Patent, the Company acquired the PSC Patent in 2008 and as a result, became the licensor to Bio-Products for the PSC Patent pursuant to a Master License Agreement dated as of August 18, 2003 (the “PSC License Agreement”). Pursuant to the terms of the PSC License Agreement, Bio-Products (a wholly-owned subsidiary of Clean Earth Solutions, Inc., (“CES”)) is the exclusive licensee of the PSC Patent and has the right to sublicense the technology that is part of the PSC Patent (but not the BRP Patent) to any party. In addition, 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. On September 22, 2010, the Company sent a Notice of Breach to Bio-Products, which included removing the exclusivity of the license. We received a response from Bio-Products on November 5, 2010 disputing our claims. In February 2011, we became aware that Bio-Products effected a transfer of the license in violation of the PSC License Agreement. As a result, on March 21, 2011, we sent a notice of termination to Bio-Products and the transferee terminating the License Agreement. In June 2011, Steve Vande Vegte, a shareholder in CES, filed a lawsuit against various parties, including the Company. The only Cause of Action against the Company is for Declaratory Relief seeking to avoid our March 2011 termination of the license to which Mr. Vande Vegte is not a party. On August 5, 2011, the Company filed a demurrer requesting that the court dismiss the case on the grounds that Mr. Vande Vegte lacks standing to pursue a claim concerning the license and that the claim raised in the complaint is not ripe. The court granted our demurrer to dismiss Cleantech from this lawsuit on December 8, 2011.

25 Van Keuren LLC

As discussed in Note 3 – Mergers/Acquisitions, the Company entered into an Acquisition Agreement with 25 Van Keuren LLC (“Van Keuren”). The total assets of Van Keuren at the time of the acquisition were approximately $51,000. The assets were recorded as an intangible asset in our consolidated financial statements; however, as of August 29, 2018, the Company’s investment in Van Keuren was divested and the related intangibles were written off.

Net Loss per share – The Company calculates basic loss per share (“EPS”) and diluted EPS. EPS is computed as net earnings (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, 2019 and December 31, 2018, the Company had options, warrants and other convertible securities to purchase an aggregate of approximately 84 million and 86 million shares, respectively, of our Common Stock, 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 statement of operations.

The Company recognizes share-based compensation expense for all share-based payment awards including stock options and restricted stock issued to employees, directors and consultants measured at the grant date, based on the estimated fair value of the award, and expense is recognized over the requisite service period. The Company has no awards with market or performance conditions.

In September 2013, the Company granted options under the Stock Plan to purchase an aggregate of 1,000,000 shares of Common Stock to two part-time employees (newly hired CTO and VP–BD) in which one-third will vest ratably beginning in September 2014, with an exercise price of $0.10.

In February 2016, the Board approved Common Stock grants to a member of management, and certain Board members, for 4.0 million shares, in the aggregate, of restricted Common Stock. Additionally, the Board approved the issuance of stock option agreements to a member of management and certain consultants for the purchase of 3.5 million shares, in the aggregate, of Common Stock. The Board granted these awards in recognition of the efforts of the recipients towards the furtherance and implementation of the Company’s strategic plan and to induce the recipients to continue those efforts on behalf of the Company. Based on the foregoing, the Board determined the grants were in the best interest of the Company and its stockholders. All of the share grant awards vest immediately and were issued pursuant to Regulation D promulgated under the Securities Act of 1933, as amended (the “Securities Act”), or Section 4(a)(2) of the Securities Act, and will therefore be “restricted securities” as such term is used in Rule 144 of the Securities Act. The option agreements were issued outside of the Company’s 2007 Stock Option Plan and carry the following terms: seven-year agreements, vesting in thirds ratably over three years, and are exercisable at the Company’s closing stock price as of the date of the grant. These options were calculated to have no value. Accordingly, there was no share-based compensation expense recorded in general and administrative expense.

In February 2016, the Company issued a stock option agreement to a consultant for the purchase of 100,000 shares of Common Stock. The option agreement was issued outside of the Company’s 2007 Stock Option Plan and carries the following terms: seven-year agreement, vesting in thirds ratably over three years, and are exercisable at the Company’s closing stock price as of the date of the grant.

The shares and options issued to Board members and management were in recognition of the efforts of the recipients towards the furtherance and implementation of the Company’s strategic plan and to induce the recipients to continue those efforts on behalf of the Company. Total expense related to these grants for the three months ended March 31, 2019 and 2018, was $11,400 and $13,400, respectively (included in our general and administrative expense).

All of the share grant awards vest immediately and were issued pursuant to Regulation D promulgated under the Securities Act, or Section 4(a)(2) of the Securities Act, and will therefore be “restricted securities” as such term is used in Rule 144 of the Securities Act. The option agreements carry the following terms: seven-year agreements, vesting in thirds ratably over three years, and are exercisable at the Company’s closing stock price as of the date of the grant.

The Company is in its development stage and is 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 are the exclusive licensee in the United States and Canada of patented technology, which we refer to as our Biomass Recovery Process, that cleans and separates MSW and generates a clean, homogeneous biomass feedstock that we believe can be converted into various energy products. Our license permits us to use the biomass we derive from MSW to produce all energy products. In addition, we own the patent for a pressurized steam classification technology originally developed by the University of Alabama in Huntsville that we refer to as our PSC technology. The PSC technology is the underlying technology upon which the Biomass Recovery Process is based. Prior to March 2011, we had licensed the PSC technology to Bio-Products International, Inc. (“Bio-Products”). However, pursuant to a settlement agreement with Bio-Products in March 2009, we had the right to use the Biomass Recovery Process technology worldwide, for any product that we desired and with no royalty due to Bio-Products. We terminated the license to Bio-Products in March 2011 as further described in the section entitled “Intellectual Property Terms.”

We are a Delaware corporation. 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 at that time was seeking to commercialize various technologies for the processing of waste materials into usable products. 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.

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 our current capital and other existing resources are not sufficient to fund the implementation of our business plan or our required working capital. We will require substantial additional capital to implement our business plan and we may be unable to immediately obtain the capital required to continue operating.

Recent Developments

25 Van Keuren LLC

On June 23, 2016, CleanTech entered into an Acquisition Agreement with 25 Van Keuren LLC, a New Jersey Limited Liability Company (“Van Keuren”) pursuant to which the Company acquired 99% of the outstanding membership interests in Van Keuren and the former members of Van Keuren retained a 1% interest. As payment for the acquisition, the Company issued in the aggregate 1,000,000 shares of restricted Common Stock of the Company (par value $0.001) to certain holders of membership interests in Van Keuren. As of the close of business on June 23, 2016, the Company stock quote was $0.05. Van Keuren has had no operations or revenue since inception and has solely been working towards obtaining the permits required to operate a municipal solid waste transfer station and material recovery facility (“TS/MRF”). The total assets of Van Keuren at the time of the acquisition were $51,000 (2.3% of the Company’s assets). The liabilities and equity consisted of accounts payable of $27,000 and member equity of $24,000. As of August 29, 2018, the Company’s investment in Van Keuren was divested pursuant to a Settlement Agreement and Release among the Company and the former members of Van Keuren (the “Van Keuren Settlement Agreement”), and the related intangible assets were written off.

The Solid Waste Management Plan of the New Jersey Department of Environmental Protection (“DEP”), following certification of an amendment to the New Jersey Sports and Exposition Authority, includes the proposed operation of a TS/MRF at a site located in Jersey City, New Jersey. CleanTech and Van Keuren intend to seek the necessary permits and approvals from the New Jersey DEP to build, own and operate the TS/MRF. As part of the Van Keuren Settlement Agreement, CleanTech acquired a one-year option to lease certain property located in Jersey City within 30 days after the final permit issues from the New Jersey DEP, which expires on August 29, 2019. The Company intends to: (1) install its Biomass Recovery Process on the site, and (2) operate the TS/MRF. Costs incurred towards obtaining the required permits were recorded as an intangible asset on our consolidated financial statements. These costs were removed from the consolidated financial statements as a part of the divestiture of CleanTech’s interest in Van Keuren.

Investments

In August 2013, the Company commenced an offering of units, under a Subscription Agreement, at a purchase price of $1,000 per unit (Equity Offering 8/13). Each unit consists of: (i) 10,000 shares of the Company’s authorized but unissued restricted Common Stock, par value $0.001 (“Common Stock”) and (ii) warrants to purchase 30,000 additional shares of Common Stock for a three-year period from the date of issuance of the units at an initial exercise price of $0.15 per share. As of May 13, 2019, the Company has issued 7,635,000 restricted shares of our Common Stock in exchange for $763,500 in investment in this offering.

Table of Contents

All of the promissory notes in our 2009, 5/12, 11/10, 2/14 and 2015 Offerings are now due. As of May 13, 2019, approximately $4.3 million is currently due, including interest. We will work with each remaining note holder to exchange, or convert, these promissory notes. There can be no assurance that we will reach agreements with any or all of these note holders and we may be required to repay such amounts.

In May 2018, the Company issued a convertible note payable to a current Board of Directors member in the amount of $30,000, with a 6% interest rate, due May 2019.

In January 2019, the Company issued a promissory note to a current note holder in the amount of $95,385, which replaced past notes issued on January 7, 2011 and January 28, 2011, plus accrued interest.

In March 2019, the Company issued a convertible note payable to a current Board of Directors member in the amount of $60,000.

Plan of Operation

Our focus is to secure sufficient capital to fund our current working capital requirements and the construction of a commercial plant as described further in this section. We have had an ongoing lack of liquidity. Currently, we do not have sufficient capital to continue to fund our proposed operations and are relying on the minimal assets on hand to fund our limited operations and corporate existence. All of our on-going and proposed developments/projects require a significant amount of capital that we currently do not have. While we continue to pursue outside sources of funding, we have not had success securing meaningful amounts of outside capital in recent years. As a result, we can provide no assurance that we will secure any source of funding in the immediate time frame required and the failure to do so will likely result in an inability to continue operations.

Our company was initially conceived as a fully-integrated producer of cellulosic 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 and initiated a plan to consolidate the ownership and/or rights to use intellectual property around this technology. The technology is currently in commercial use in Coffs Harbor, Australia by an operator not owned by the Company (the “Third-Party Operator”). As a result, we believe this technology could be implemented commercially in the United States and elsewhere. In furtherance of our focus, we are continuing our ongoing search for an outside source of financing to design and build a commercial biomass recovery plant to provide biomass feedstock for customer evaluation and trial purchases. Initially, the biomass feedstock output is expected to be sold or provided to electric utilities, power and steam producers, and biofuel and chemical research firms for evaluation. In addition to research and development, the Company is also working towards licensing and/or developing potential commercial projects. These projects plan to focus on cleaning and separating MSW into its component parts in order to obtain: (i) a homogenous feedstock of cellulosic biomass for producing energy and other chemical products and (ii) recyclable products (metals, plastics).

Jersey City

As described earlier under Recent Developments, the Company’s primary focus is to seek the capital required to obtain the necessary permits and approvals from the New Jersey DEP and to build, own and operate the TS/MRF in Jersey City, NJ. As part of the Van Keuren Settlement Agreement, CleanTech acquired a one-year option to lease the property located in Jersey City which expires on August 29, 2019 and intends to: (1) install its Biomass Recovery Process on the site, and (2) operate the TS/MRF. The Company may initially operate this location as a transfer station (after receiving the required permits and approvals) while designing and installing our Biomass Recovery Process equipment on the site. The biomass feedstock output would then be expected to be sold or provided to electric utilities, power and steam producers, power and steam producers, and biofuel and chemical research firms for evaluation.

Biomass Feedstock Production

We are working to develop one or more other locations where waste collected would be processed using our technology and the biomass produced used to create heat and/or power. Initially, the biomass feedstock output is expected to be sold or provided to electric utilities, power and steam producers, and biofuel and chemical research firms for evaluation. In addition to research and development, the Company also plans to license and/or develop potential commercial projects.

In addition to the developments we are currently contemplating, from time to time other development opportunities are presented to us and we evaluate those potential developments. If we are able to operate a plant, and thereafter refine 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.

Any development of commercial plants and/or implementation of the licensing of our technology described above will require significant additional capital, which we currently do not have. To date, we have not been successful in raising the amount of capital necessary to implement our business plan and we cannot provide any assurance that we will be able to raise sufficient additional capital. While we anticipate that financing for the commercial biomass recovery plant and these other potential projects could also be provided in part via tax exempt bond financing or through the use of loan guarantees from local, state and federal authorities, we have not secured any such financing and there can be no assurance that we will be able to secure any such financing.

Bio-Fuel and Bio-Chemical Joint Testing/Research

If we are able to process MSW into biomass through our potential future biomass recovery plant and/or in future commercial vessels, we hope to enter into joint research agreements with companies looking to process biomass in their system(s) for various types of energy and chemical production. We believe that this testing and research could provide possible revenue streams, projects and additional opportunities for use of our biomass.

In February 2012, we entered into a Confidentiality Agreement and Material Transfer Agreement with Sweetwater Energy, Inc. (“Sweetwater”), a renewable energy company with patent-pending technology to produce sugars from several types of biomass for use in the biofuel, biochemical and bioplastics markets. We agreed and coordinated with the Third-Party Operator in Australia to ship 10 pounds of biomass produced at the Third-Party Operator’s facility to the Sweetwater lab for testing. The shipment arrived in May 2012 and Sweetwater has completed their initial testing. In June 2011, we entered into a Confidential Disclosure and Sampling Agreement with Novozymes North America, Inc., a developer of industrial enzymes, microorganisms, and biopharmaceutical ingredients for conversion into a variety of energy and chemical products. In July 2011, we supplied a sample of our biomass product for testing in their enzymatic hydrolysis process. Some initial testing was completed during the 3^rd Quarter of 2011. We expect further testing to occur for both of these companies and for possible additional companies upon securing the requisite financing to build a biomass recovery plant to process MSW.

New Technologies; Commercializing Existing Technologies

Because of our ability to produce a clean, homogenous biomass feedstock, we may be presented with the opportunity to partner with or acquire new technologies once we become operational. In addition to developing our current technologies, we intend to continue to add technologies to our suite of solutions that complement our core operations. We believe that our current technologies and aspects of technologies in development or contemplation 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.

Table of Contents

To commercialize our technology, we anticipate we will need to:

●

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 our licensed territories.

Our ability to implement this strategy is heavily dependent 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 in our consolidated statements of operations for the three months ended March 31, 2019 and 2018. The Company’s activities and related primary expenses are in the following categories: General and administrative – payroll, general office expenses, travel, and business insurance; Professional fees - consulting, accounting and legal fees; Other expense (income) – interest expense on convertible notes payable and interest income on notes receivable related to restricted stock grants.

	Three months ended March 31,
	2019			2018			Change
Costs and expenses:
General and administrative	$	48,459		$	53,971		$	(5,512	)
Professional fees		46,118			65,516			(19,398	)
		94,577			119,487			(24,910	)

Other expense (income):
Interest expense		65,380			61,387			3,993
Interest income, net of accrued interest written-off		(559	)		(886	)		327

Net loss applicable to common stockholders	$	159,398		$	179,988		$	(20,590	)

General and Administrative – The decrease was due to a decrease in restricted stock grants of $4,000 and a decrease in corporate filling fees of $1,300.

Professional Fees – The decrease was due to a decrease in legal fees of $20,000.

Interest Expense – The increase was due to the compounding effect of interest on our notes payable.

Liquidity and Capital Resources

As a development-stage company, we have no revenues and will be required to obtain an outside source of capital in order to execute our business plan and commercialize our products. Beginning in September 2008 and as of May 13, 2019, we have raised an aggregate of: (i) approximately $3.5 million in separate offerings of units comprised of notes payable and warrants in separate offerings from 2008 through 2019 and (ii) $763,500 in an equity offering of restricted Common Stock pursuant to Subscription Agreements conducted during August of 2013. We are continuing to explore opportunities to raise cash through the issuance of these units and other financing opportunities, however, to date we have not been successful in doing so. As of May 13, 2019, our current cash and other assets are not sufficient to fund our operations. As of March 31, 2019, we had a significant working capital deficit. Our liabilities are substantially greater than our current assets. Our only significant assets are our intellectual property rights, which are intangible and not readily convertible into liquid assets.

Table of Contents

We are attempting to identify one or more potential sources of additional financing, such as through the sale of additional equity, various government funding opportunities and/or possibly through strategic alliances with larger energy or waste management companies. The Company will continue to explore, and if identified, evaluate financing alternatives and/or other transactions, including potentially retaining a financial advisor. However, we may not be successful in securing additional financing. If we are not able to obtain additional financing in the immediate future, we will be required to further delay our development until such financing becomes available. 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.

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 consolidated 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, 2018, filed with the Securities and Exchange Commission on April 1, 2019. Our critical accounting policies and estimate assumptions have not changed during the three months ended March 31, 2019.

Item 3. Quantitative and Qualitative Disclosures About Market Risk - Not applicable

Item 4. 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.

Table of Contents

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, which was performed based on the criteria set forth in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO), our chief executive officer and interim chief financial officer concluded that our disclosure controls and procedures (as defined in Rule 15d-15(e) promulgated under the Securities Exchange Act of 1934) are effective at that reasonable assurance level at March 31, 2019. Further, the design of a control system must reflect the fact that there are resource constraints, including, but not limited to having one full-time employee (chief executive 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, 2019, 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.

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.

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

In March 2019, the Company issued a convertible note in the principal amount of $60,000 to a current Board of Directors member. This convertible note bears simple interest of 6% and matures in March 2020. This convertible note may be converted into shares of the Company’s Common Stock at a price per share equal to $.04. The offering of this convertible note was exempt from registration under the Securities Act in accordance with Section 4(a)(2) thereof, as a transaction by the issuer not involving a public offering.

Item 3. Defaults Upon Senior Securities

Certain promissory notes in our offering of units comprised of convertible promissory notes and warrants, commenced in April 2009 (2009, 11/10, 5/12, 2/14 and 2015 Offerings) are due. As of March 31, 2019, approximately $4.8 million (including approximately $1.5 million of accrued interest) was due and payable. We plan to work with each remaining note holder to exchange, or convert, these promissory notes. There can be no assurance that we will reach agreements with any or all of these note holders and we may be required to repay such amounts.
