Basis of Presentation and Going Concern
Basis of Presentation and Going Concern	Note 1. Basis of Presentation and Going Concern Nature of Operations In March 2020, the World Health Organization declared the outbreak of a novel coronavirus (COVID-19) as a pandemic which continued to spread throughout the United States and globally and more recently in the United States intermittent increases in cases reported, as well as those from new strains of the virus. Vaccines developed for the initial strain of the virus have been released and are being distributed. The Company continues to monitor the near term and longer term impacts of COVID-19 and the related business and travel restrictions and other changes intended to reduce its spread, and its impact on operations, financial position, cash flows, inventory, supply chains, purchasing trends, customer payments, and the industry in general, in addition to the impact on its employees. Due to the nature of the pandemic, the magnitude and duration of the pandemic and its impact on the Company’s operations, liquidity and financial performance will depend on certain developments, including duration, spread and reemergence of the outbreak, its impact on our customers, supply chain partners and employees, and the range of governmental and community reactions to the pandemic, which are uncertain and cannot be fully predicted at this time. Basis of Presentation The accompanying condensed consolidated financial statements should be read in conjunction with the Company’s financial statements for the year ended December 31, 2020, which contains the audited financial statements and notes thereto, for the years ended December 31, 2020 and 2019 included within the Company’s Form 10-K filed with the Securities and Exchange Commission (“SEC”) on April 16, 2021. The financial information as of December 31, 2020 presented hereto is derived from the audited consolidated financial statements presented in the Company’s audited consolidated financial statements for the year ended December 31, 2020. The interim results for the three and nine months ended September 30, 2021 is not necessarily indicative of the results to be expected for the year ending December 31, 2021 or for any future interim periods. As of September 30, 2021 and December 31, 2020, the Company's active wholly-owned subsidiaries were BioHiTech America, LLC, BioHiTech Europe Limited, BHT Financial, LLC and BHT Renewables LLC (formerly E.N.A. Renewables LLC), and its controlled subsidiary was Refuel America LLC (68.2% and 60%, respectively) and its wholly-owned subsidiaries Apple Valley Waste Technologies Buyer, Inc., Apple Valley Waste Technologies, LLC, New Windsor Resource Recovery LLC and Rensselaer Resource Recovery LLC and its controlled subsidiary Entsorga West Virginia LLC (93.5% and 88.7%, respectively). As each of these subsidiaries operate as environmental-based service companies, we did not deem segment reporting necessary. Reclassifications to certain prior period amounts have been made to conform to current period presentation. These reclassifications have no effect on previously reported net loss. Going Concern and Liquidity The accompanying consolidated financial statements have been prepared on a going concern basis, which contemplates the realization of assets and the satisfaction of liabilities in the normal course of business. These consolidated financial statements do not include any adjustments relating to the recovery of the recorded assets or the classification of the liabilities that might be necessary should the Company be unable to continue as a going concern. The ability of the Company to continue as a going concern is dependent on management’s further implementation of the Company’s on-going and strategic plans, which include continuing to raise funds through equity and/or debt raises. Should the Company be unable to raise adequate funds, certain aspects of the on-going and strategic plans may require modification.

Summary of Significant Accounting Policies	Note 3. Summary of Significant Accounting Policies The condensed consolidated financial statements have been prepared by the Company in accordance with the rules and regulations of the SEC on a consistent basis with and should be read in conjunction with our audited financial statements for the year ended December 31, 2020. Certain information has been condensed or omitted as permitted by the SEC, although we believe the disclosures that are made are adequate to make the information presented herein not misleading. ​ Recent Accounting Standards: The Company has not implemented any recent accounting standards during the nine months ended September 30, 2021. The Company has not implemented the following accounting standards: In June 2016, the FASB issued ASU 2016-13, Measurement of Credit Losses on Financial Instruments In March 2020, the FASB issued ASU No. 2020-04, “Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting.” The amendments in this update provide optional guidance for a limited period of time to ease the potential burden in accounting for (or recognizing the effects of) reference rate reform on financial reporting as the market transitions from the London Interbank Offered Rate (LIBOR) and other interbank offered rates to alternative reference rates. The amendments in this update were effective upon issuance for all entities through December 31, 2022. The Company is currently evaluating the effect the updated standard will have on its financial position, results of operations or financial statement disclosure. In August 2020, the FASB issued ASU No. 2020-06, Debt with Conversion and other Options (Subtopic 470-20) and Derivatives and Hedging - Contracts in Entity’s Own Equity (Subtopic 815-40). The new guidance eliminates the beneficial conversion and cash conversion accounting models for convertible instruments. It also amends the accounting for certain contracts in an entity’s own equity that are currently accounted for as derivatives because of specific settlement provisions. In addition, the new guidance modifies how particular convertible instruments and certain contracts that may be settled in cash or shares impact the diluted earnings per share computation. This guidance is effective as of January 1, 2022 (Early adoption is permitted effective January 1, 2021). The Company is currently evaluating the effect the updated standard will have on its financial position, results of operations or financial statement disclosure. There have been no other recent accounting standards or changes in accounting standards that have been issued but not yet adopted that are of significance, or potential significance, to the Company.

The Company did not meet certain of its senior secured note’s financial covenants as of September 30, 2021 and December 31, 2020, and has received a waiver for such non-compliance through September 30, 2021. Despite its current compliance under the waiver, until such time as the Company regains compliance or receives a waiver of such covenants for a year beyond the balance sheet date, under current GAAP accounting rules the senior secured note amounting to $3,746,025 has been classified as current debt. The WVEDA Bonds agreement and indenture of trust place restrictions on the borrower and its members regarding additional encumbrances on the property, disposition of the property, and limitations on equity distributions. The loan agreement also provides for financial covenants. As of September 30, 2021 and December 31, 2020 the Company was not in compliance with all of the financial covenants and subsequently was in default on principal repayments due in 2020 and 2021 and has entered into a forbearance agreement with the bond trustee that provides, they will not accelerate the repayment of the bonds due to the defaults through October 1, 2022. On May 19, 2021 the Company’s subsidiary Entsorga West Virginia, LLC (“EWV”) executed a series of notes related to the settlement of a previously recognized claim (See Note 11) with Entsorga S.p.A.(“ESpA”), the parent company of Entsorga USA, Inc., a non-controlling member of the Company’s EWV subsidiary. The series of notes are comprised of 24 monthly notes of $41,725 bearing interest at 1% if not paid at maturity, of which 4 notes, totaling $166,900 are only payable if ESpA successfully repairs certain equipment at the EWV facility. In addition to the 24 notes, there is a note for $253,296 (“default note”) that is only payable in the event of a default on the other notes due to ESpA. The 24 monthly notes totaling $1,001,400 have been discounted at the rate of 6.6%, resulting in an initial net balance due of $917,421, which is the amount that the Company had previously accrued for the claims made. The default note has not been recognized as the amount is contingent upon future events.

Utilizing the increase in intrinsic value of the underlying common shares into which the preferred shares may be converted into based on the prior conversion rate and post-dilution protection trigger conversion rate, the Company recognized a deemed dividend of $304,337 relating to the convertible preferred shares. Under the terms of the Company’s senior lender agreements, the Company is restricted from paying dividends in cash, but is allowed to pay dividends in common stock. The Company, since its merger in 2015, has not paid any cash or stock dividends on common stock.

Summary of Significant Accounting Policies
Recent Accounting standards	Recent Accounting Standards: The Company has not implemented any recent accounting standards during the nine months ended September 30, 2021. The Company has not implemented the following accounting standards: In June 2016, the FASB issued ASU 2016-13, Measurement of Credit Losses on Financial Instruments In March 2020, the FASB issued ASU No. 2020-04, “Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting.” The amendments in this update provide optional guidance for a limited period of time to ease the potential burden in accounting for (or recognizing the effects of) reference rate reform on financial reporting as the market transitions from the London Interbank Offered Rate (LIBOR) and other interbank offered rates to alternative reference rates. The amendments in this update were effective upon issuance for all entities through December 31, 2022. The Company is currently evaluating the effect the updated standard will have on its financial position, results of operations or financial statement disclosure. In August 2020, the FASB issued ASU No. 2020-06, Debt with Conversion and other Options (Subtopic 470-20) and Derivatives and Hedging - Contracts in Entity’s Own Equity (Subtopic 815-40). The new guidance eliminates the beneficial conversion and cash conversion accounting models for convertible instruments. It also amends the accounting for certain contracts in an entity’s own equity that are currently accounted for as derivatives because of specific settlement provisions. In addition, the new guidance modifies how particular convertible instruments and certain contracts that may be settled in cash or shares impact the diluted earnings per share computation. This guidance is effective as of January 1, 2022 (Early adoption is permitted effective January 1, 2021). The Company is currently evaluating the effect the updated standard will have on its financial position, results of operations or financial statement disclosure. There have been no other recent accounting standards or changes in accounting standards that have been issued but not yet adopted that are of significance, or potential significance, to the Company.
