Notes to Financial Statements
Organization, Consolidation, Basis of Presentation, Business Description and Accounting Policies [Text Block]	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 that will provide the capital for us to design, build, and operate a commercial biomass recovery plant that will allow us to produce biomass feedstock for customer evaluation, trial purchases, and/or be used in equipment selection for power generation and possibly combined heat and power (“CHP”) production. Initially, the biomass feedstock output is expected to be sold or provided to electric utilities, power and steam producers, power and CHP equipment suppliers, and biofuel research firms for evaluation. In addition to seeking a source of funding for plant development, the Company hopes to license and/or develop potential commercial projects as they present themselves. Our development plan is 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, aluminum). Our plans may also include the possibility of operating a MSW transfer station where we could install our technology. 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, 2018 are not necessarily indicative of the results that may be expected for the year ended December 31, 2018. 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, 2017, filed with the Securities and Exchange Commission (“SEC”) on April 2, 2018.
