Basis Of Presentation And Going Concern [Abstract]
Basis Of Presentation And Going Concern Disclosure [Text Block]	Note 1. Basis of Presentation and Going Concern Nature of Operations - BioHiTech Global, Inc. (the “Company” or “BioHiTech”) through its wholly-owned and its controlled subsidiaries offers cost-effective and technologically innovative advancements integrating technological, biological and mechanical engineering solutions for the control, reduction and / or reuse of organic and municipal waste. As of March 31, 2019 and December 31, 2018, the Company’s active wholly-owned subsidiaries were BioHiTech America, LLC, BioHiTech Europe Limited, BHT Financial, LLC and E.N.A. Renewables LLC, and its controlled subsidiary was Refuel America LLC ( 60 78.2 As of March 31, 2018, the Company’s active wholly-owned subsidiaries were BioHiTech America, LLC, BioHiTech Europe Limited, BHT Financial, LLC and E.N.A. Renewables LLC, and New Windsor Resource Recovery LLC. Basis of Presentation - The presented. The accompanying condensed consolidated financial statements should be read in conjunction with the Company’s financial statements for the year ended December 31, 2018, which contains the audited financial statements and notes thereto, for the years ended December 31, 2018 and 2017 included within the Company’s Form 10-K filed with the Securities and Exchange Commission (“SEC”) on April 1, 2019. The financial information as of December 31, 2018 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, 2018. The interim results for the three months ended March 31, 2019 are not necessarily indicative of the results to be expected for the year ending December 31, 2019 or for any future interim periods. 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 - For the three months March 31, 2019, the Company had a consolidated net loss of $ 2,261,167 1,921,303 1,212,649 At March 31, 2019, consolidated total stockholders’ equity amounted to $8,777,709, consolidated stockholders’ equity attributable to parent amounted to $2,486,715 and the Company had a consolidated working capital deficit of $3,214,265. The Company does not yet have a history of financial profitability. Historically the principal source of liquidity has been the issuance of debt and equity securities. Presently, the Company does not have firm commitments to fund its present operational and strategic plans. These factors raise substantial doubt about the Company’s ability to continue as a going concern. 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 debt and/or equity raises. Should the Company be unable to raise adequate funds, certain aspects of the on-going and strategic plans may require modification. The Company is presently in the process of raising additional debt and capital for general operations and for investment in several strategic initiatives, as well as commercial debt to support its leasing activities. There is no assurance that the Company will be able to raise sufficient debt or capital to sustain operations or to pursue other strategic initiatives

Summary of Significant Accounti

Summary of Significant Accounting Policies	3 Months Ended

Accounting Policies [Abstract]
Significant Accounting Policies [Text Block]	Note 2. Summary of Significant Accounting Policies Use of Estimates Foreign Operations — Assets and liabilities denominated in foreign currencies are translated into U.S. dollars at the exchange rates existing at the respective balance sheet dates. Income and expense items are translated at the average rates during the respective periods. Translation adjustments resulting from fluctuations in exchange rates are recorded as a separate component of other comprehensive income (loss) while transaction gains and losses are recorded in net earnings (loss). The Company pays Value Added Tax (“VAT”) or similar taxes (“input VAT”) within the normal course of its business in in the United Kingdom on merchandise and/or services it acquires. The Company also collects VAT or similar taxes on behalf of the government (“output VAT”) for merchandise and/or services it sells. If the output VAT exceeds the input VAT, then the difference is remitted to the government, usually on a monthly basis. If the input VAT exceeds the output VAT, this creates a VAT receivable. The Company either requests a refund of this VAT receivable or applies the balance to expected future VAT payables. Product and Services Revenue Recognition — T 1. Identify the contract with a customer; 2. Identify the performance obligations in the contract; 3. Determine the transaction price of the contract; 4. Allocate the transaction price to the performance obligations in the contract; 5. Recognize revenue when the performance obligations are met or delivered. The Company’s performance obligations are satisfied at the point in time when products are shipped to the customer, which is when the customer has title and control. Therefore, the Company’s contracts have a single performance obligation (shipment of product). The Company primarily receives fix consideration for sales of products. Management advisory fees are recognized over the term of the agreement. The Company records taxes collected from customers and remitted to governmental authorities on a net basis. Lease Revenue Recognition — The Company selected the practical expedient not to separate non-lease components from lease components. The Company recognizes revenue from the rental of the digester units ratably on a monthly basis over the term of the lease, as it has determined that the rental agreements entered into in connection with its digester units qualify as operating leases, for which the Company is the operating lessor. In order to determine lease classification as operating, the Company evaluates the terms of the rental agreement to determine if the lease includes any of the following provisions which would indicate sales type lease treatment:  The lease transfers ownership of the underlying asset to the lessee by the end of the lease term,  The lease grants the lessee an option to purchase the underlying asset that the lessee is reasonably certain to exercise,  The Lease term is for the major part of the remaining economic life of the underlying asset. However, if the commencement date falls at or near the end of the economic life of the underlying asset, this criterion shall not be used for purposes of classifying the lease,  The present value of the sum of the lease payments and any residual value guaranteed by the lessee that is not already reflected in the lease payments equals or exceeds substantially all of the fair value of the underlying asset or · The underlying asset is of such a specialized nature that it is expected to have no alternative use to the lessor at the end of the lease term. Restricted Cash — Includes Restricted cash that is restricted as to its use, as it is held by a trustee in accordance with the West Virginia Economic Development Authority bond agreement. These amounts are held by the Company’s trustee in various bank accounts segregated for specific uses related to the construction and operation of the resource recovery facility. Amounts required to meet current operations of the Company have been classified as current in the accompanying consolidated balance sheets. HEBioT Facility under Construction — High Efficiency Biological Treatment (“HEBioT”) facility under construction include all costs incurred to bring an asset to the condition and location necessary for its intended use. Included in the capitalized costs are construction, legal, leasehold improvements, and interest. Once placed into service, these costs will be depreciated over their estimated useful lives on a straight-line basis. MBT Facility Development Costs — Investments in Unconsolidated Entities —The Company utilizes the equity method of accounting for investments in companies if the investment provides the ability to exercise significant influence, but not control, over operating and financial policies of the investee. The Company’s proportionate share of net income or loss is included in the Company’s consolidated operations as earning or loss from unconsolidated equity basis investments. In circumstances were the Company does not have the ability to exercise significant influence or control over the operating and financial policies of the investee, the investment is Deferred Financing Costs — Deferred financing costs relating to issued debt are included as a reduction to the applicable debt and amortized as interest expense over the term of the related debt instruments. Income Taxes — Deferred income taxes are determined based on the estimated future tax effects of differences between the financial statement and tax bases of assets and liabilities given provisions of enacted laws. Deferred income tax provisions and benefits are based on changes to the asset or liabilities from year to year. In providing for deferred taxes, the Company considers tax regulations of the jurisdictions in which it operates, estimates the future taxable income and available tax planning strategies. If tax regulations, operating results or the ability to implement tax planning and strategies vary, adjustments to the carrying value of deferred tax assets and liabilities may be required. Valuation allowances are recorded related to deferred tax assets based on the “more than likely” criteria. The Company recognizes the financial statement benefit of a tax position only after determining that the relevant tax authority would more likely than not sustain the position following an audit. For tax positions meeting the more likely than not threshold, the amount recognized in the financial statements is the largest benefit that has a greater than 50 percent likelihood of being realized upon ultimate settlement with the relevant tax authority. Loss per Share — The Company computes basic loss per share using the weighted-average number of shares of common stock outstanding and diluted loss per share, while the diluted loss per share also includes the effects of dilutive instruments using the “treasury method.” Dividends attributable to preferred stock, whether declared or accrued, are deducted from income attributable to common shareholders for purposes of earnings per share. The Company’s potential dilutive instruments include convertible preferred stock, options, convertible debt and warrants. These instruments have not been considered in the calculation of diluted loss per share as they are anti-dilutive for the reported periods.

Leases, Operating [Abstract]
Lessor, Operating Leases [Text Block]	Note 19. Leases Effective January 1, 2019, the Company implemented Accounting Standards Codification 842, Leases. The guidance requires lessees to recognize most leases on the balance sheet but does not change the manner in which expenses are recorded in the income statement. The two permitted transition methods under the guidance are the modified retrospective transition approach, which requires application of the guidance for all comparative periods presented, and the cumulative effect adjustment approach, which requires prospective application at the adoption date. The Company utilized the optional transition method to assess the impact of this guidance on the Company’s financial statements and related disclosures, including the increase in the assets and liabilities on our balance sheet from lessee perspective. The Company completed a comprehensive review of its leases that were impacted by the new guidance. As part of the adoption, the Company elected the ‘package of practical expedients,’ which permits the Company not to reassess under the new standard the Company’s prior conclusions about lease identification, lease classification and initial direct costs, therefore the Company did not restate prior comparative periods. The Company rents its headquarters and attached warehousing space from a related party (see Note 20) and has a land lease relating to the Martinsburg, WV HEBioT facility under operating leases. The HEBioT facility land lease has an initial term of 30 years, plus four 5-year extensions. For purposes of our determination of lease liabilities, extensions were not included. As the leases do not provide an implicit rate, the Company used incremental borrowing rates in determining the present value of lease payments. For the HEBioT facility land lease a rate of 11% was utilized and a rate of 10.25% was used on the other leases. The current portion of the lease liabilities 101,477 is included in accrued expenses and liabilities. Total rent expense under all operating leases amounted to $67,532 and $33,101 for the three months ended March 31, 2019 and 2018, respectively. Maturities of lease liabilities under these leases, which have a weighted average remaining term of 24.5 Year Ending December 31, 2019 (remaining) $ 146,470 2020 150,926 2021 113,000 2022 113,000 2023 and thereafter 3,095,500 Total lease payments 3,618,896 Less imputed interest (2,597,706 ) Present value of lease liabilities $ 1,021,190 During the three months ended March 31, 2019, the Company recognized operating lease right of use assets in exchange for lease liabilities amounting to $1,045,755 and had operating cash flows for operating leases amounting to $72,765 .

New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
New Accounting Pronouncements and Changes in Accounting Principles [Text Block]	Note 22. Recent Accounting Standards During the three months ended March 31, 2019, the Company adopted the following recent accounting standards: Leases — In February 2016, the FASB issued new lease accounting guidance (ASU No. 2016-02, Leases), which has subsequently been amended by ASU No. 2018-11, Leases in July 2018. Under the new guidance, at the commencement date, lessees will be required to recognize a lease liability, which is a lessee‘s obligation to make lease payments arising from a lease, measured on a discounted basis; and a right-of use asset, which is an asset that represents the lessee’s right to use, or control the use of, a specified asset for the lease term. The new guidance is not applicable for leases with a term of 12 months or less. Lessor accounting is largely unchanged. Public business entities should apply the amendments in ASU 2016-02 for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early application is permitted upon issuance. Lessees (for capital and operating leases) and lessors (for sales-type, direct financing, and operating leases) must apply a modified retrospective transition approach for leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements. The modified retrospective approach would not require any transition accounting for leases that expired before the earliest comparative period presented. Lessees and lessors may not apply a full retrospective transition approach. ASU 2018-11 provides that under certain instances lessors may not be required to separate the components of the contracts. As a lessor of digester equipment under operating leases, the new guidance did not have a material impact on the financial statements. As a lessee under operating leases the adoption did not have a material impact on our financial statements, resulting in an increase of 2% to each of our total assets and total liabilities on our balance sheet, and had an immaterial impact to retained earnings as of the beginning of 2019. In March 2019, the FASB issued ASU 2019-01, Leases (Topic 842, Codification Improvements

Accounting Policies [Abstract]
Use of Estimates, Policy [Policy Text Block]	Use of Estimates
Foreign Currency Transactions and Translations Policy [Policy Text Block]	Foreign Operations — Assets and liabilities denominated in foreign currencies are translated into U.S. dollars at the exchange rates existing at the respective balance sheet dates. Income and expense items are translated at the average rates during the respective periods. Translation adjustments resulting from fluctuations in exchange rates are recorded as a separate component of other comprehensive income (loss) while transaction gains and losses are recorded in net earnings (loss). The Company pays Value Added Tax (“VAT”) or similar taxes (“input VAT”) within the normal course of its business in in the United Kingdom on merchandise and/or services it acquires. The Company also collects VAT or similar taxes on behalf of the government (“output VAT”) for merchandise and/or services it sells. If the output VAT exceeds the input VAT, then the difference is remitted to the government, usually on a monthly basis. If the input VAT exceeds the output VAT, this creates a VAT receivable. The Company either requests a refund of this VAT receivable or applies the balance to expected future VAT payables.
Revenue Recognition, Policy [Policy Text Block]	Product and Services Revenue Recognition — T 1. Identify the contract with a customer; 2. Identify the performance obligations in the contract; 3. Determine the transaction price of the contract; 4. Allocate the transaction price to the performance obligations in the contract; 5. Recognize revenue when the performance obligations are met or delivered. The Company’s performance obligations are satisfied at the point in time when products are shipped to the customer, which is when the customer has title and control. Therefore, the Company’s contracts have a single performance obligation (shipment of product). The Company primarily receives fix consideration for sales of products. Management advisory fees are recognized over the term of the agreement. The Company records taxes collected from customers and remitted to governmental authorities on a net basis.
Revenue Recognition, Leases [Policy Text Block]	Lease Revenue Recognition — The Company selected the practical expedient not to separate non-lease components from lease components. The Company recognizes revenue from the rental of the digester units ratably on a monthly basis over the term of the lease, as it has determined that the rental agreements entered into in connection with its digester units qualify as operating leases, for which the Company is the operating lessor. In order to determine lease classification as operating, the Company evaluates the terms of the rental agreement to determine if the lease includes any of the following provisions which would indicate sales type lease treatment:  The lease transfers ownership of the underlying asset to the lessee by the end of the lease term,  The lease grants the lessee an option to purchase the underlying asset that the lessee is reasonably certain to exercise,  The Lease term is for the major part of the remaining economic life of the underlying asset. However, if the commencement date falls at or near the end of the economic life of the underlying asset, this criterion shall not be used for purposes of classifying the lease,  The present value of the sum of the lease payments and any residual value guaranteed by the lessee that is not already reflected in the lease payments equals or exceeds substantially all of the fair value of the underlying asset or · The underlying asset is of such a specialized nature that it is expected to have no alternative use to the lessor at the end of the lease term.
Restricted Cash, Policy [Policy Text Block]	Restricted Cash — Includes Restricted cash that is restricted as to its use, as it is held by a trustee in accordance with the West Virginia Economic Development Authority bond agreement. These amounts are held by the Company’s trustee in various bank accounts segregated for specific uses related to the construction and operation of the resource recovery facility. Amounts required to meet current operations of the Company have been classified as current in the accompanying consolidated balance sheets.
HEBiot Facility under Construction [Policy Text Block]	HEBioT Facility under Construction — High Efficiency Biological Treatment (“HEBioT”) facility under construction include all costs incurred to bring an asset to the condition and location necessary for its intended use.

Investment, Policy [Policy Text Block]	Investments in Unconsolidated Entities —The Company utilizes the equity method of accounting for investments in companies if the investment provides the ability to exercise significant influence, but not control, over operating and financial policies of the investee. The Company’s proportionate share of net income or loss is included in the Company’s consolidated operations as earning or loss from unconsolidated equity basis investments. In circumstances were the Company does not have the ability to exercise significant influence or control over the operating and financial policies of the investee, the investment is
Deferred Offering Costs [Policy Text Block]	Deferred Financing Costs — Deferred financing costs relating to issued debt are included as a reduction to the applicable debt and amortized as interest expense over the term of the related debt instruments.
Income Tax, Policy [Policy Text Block]	Income Taxes — Deferred income taxes are determined based on the estimated future tax effects of differences between the financial statement and tax bases of assets and liabilities given provisions of enacted laws. Deferred income tax provisions and benefits are based on changes to the asset or liabilities from year to year. In providing for deferred taxes, the Company considers tax regulations of the jurisdictions in which it operates, estimates the future taxable income and available tax planning strategies. If tax regulations, operating results or the ability to implement tax planning and strategies vary, adjustments to the carrying value of deferred tax assets and liabilities may be required. Valuation allowances are recorded related to deferred tax assets based on the “more than likely” criteria. The Company recognizes the financial statement benefit of a tax position only after determining that the relevant tax authority would more likely than not sustain the position following an audit. For tax positions meeting the more likely than not threshold, the amount recognized in the financial statements is the largest benefit that has a greater than 50 percent likelihood of being realized upon ultimate settlement with the relevant tax authority.
Earnings Per Share, Policy [Policy Text Block]	Loss per Share — The Company computes basic loss per share using the weighted-average number of shares of common stock outstanding and diluted loss per share, while the diluted loss per share also includes the effects of dilutive instruments using the “treasury method.” Dividends attributable to preferred stock, whether declared or accrued, are deducted from income attributable to common shareholders for purposes of earnings per share. The Company’s potential dilutive instruments include convertible preferred stock, options, convertible debt and warrants. These instruments have not been considered in the calculation of diluted loss per share as they are anti-dilutive for the reported periods.
