Organization, Consolidation and Presentation of Financial Statements Disclosure [Text Block]	1. ORGANIZATION, NATURE OF BUSINESS, GOING CONCERN AND MANAGEMENT’S PLANS: Organization and nature of business: Bion Environmental Technologies, Inc. (“Bion” or “We” or the “Company”) was incorporated in 1987 patented and proprietary technology and business models that provide comprehensive environmental solutions to a significant source of pollution in United States agriculture, large scale livestock facilities known as Concentrated Animal Feeding Operations (“CAFO’s”). Application of our technology and technology platform can simultaneously remediate environmental problems and improve operational/resource efficiencies by recovering value from the CAFOs’ waste stream that has traditionally been wasted or underutilized, including renewable energy, nutrients (nitrogen and phosphorus) and clean water. Bion’s technologies (and applications related thereto) produce substantial reductions of nutrient releases (primarily nitrogen and phosphorus) to both water and air (including ammonia, which is subsequently re-deposited to the ground) from livestock waste streams based upon our operations and research to date (and third third During the 2014 201 7 third “3G 2018 no Currently, Bion is focused on using applications of its patented and proprietary waste management technologies and technology platform to pursue three 1 ( some of which may to retrofit and environmentally remediate existing CAFOs (“Retrofits”) in selected markets where: a) government policy supports such efforts (such as the Chesapeake Bay watershed, some Great Lakes Basin states, and/or other states and watersheds facing Environmental Protection Agency (“EPA”) ‘total maximum daily load’ (“TMDL”) issues, and/or b) where CAFO’s need our technology to obtain permits to expand or develop without negative environmental consequences; 2 may with multiple revenue streams, and 3 1 2 Management believes that Bion’s technology also creates the opportunity to develop Integrated Projects that profitably integrate large-scale CAFO's production with their downstream food processing facility, and in certain applications, biofuel/ethanol production. The Bion platform will provide treatment of, as well as renewable energy and by-product recovery from, both the CAFO and food processing waste streams, on-site utilization of some or all of the renewable energy generated, and potentially, biofuel/ethanol production, in an environmentally and economically sustainable manner that reduces the aggregate capital expense and operating costs for the entire integrated complex.

Significant Accounting Policies [Text Block]	2. SIGNIFICANT ACCOUNTING POLICIES Principles of consolidation: The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries, Bion Integrated Projects Group, Inc. (“Projects Group”), Bion Technologies, Inc., BionSoil, Inc., Bion Services, PA1, PA2; 58.9% Cash: The Company considers all highly liquid investments purchased with an original maturity of three Property and equipment: Property and equipment are stated at cost and are depreciated, when placed into service, using the straight-line method over the estimated useful lives of the related assets, generally three twenty l indirect incrementally identifiable costs related to the design and construction of its Integrated Projects. The Company has elected to expense all costs and filing fees related to obtaining patents (resulting in no no may not Derivative Financial Instruments: Pursuant to Accounting Standards Codification (“ASC”) Topic 815 815” may Warrants: The Company has issued warrants to purchase common shares of the Company. Warrants are valued using a fair value based method, whereby the fair value of the warrant is determined at the warrant issue date using a market-based option valuation model based on factors including an evaluation of the Company ’s value as of the date of the issuance, consideration of the Company’s limited liquid resources and business prospects, the market price of the Company’s stock in its mostly inactive public market and the historical valuations and purchases of the Company’s warrants. When warrants are issued in combination with debt or equity securities, the warrants are valued and accounted for based on the relative fair value of the warrants in relation to the total value assigned to the debt or equity securities and warrants combined. Concentrations of credit risk: The Company's financial instruments that are exposed to concentrations of credit risk consist of cash. The Company's cash is in demand deposit accounts placed with federally insured financial institutions and selected brokerage accounts. Such deposit accounts at times may not Noncontrolling interests: In accordance with ASC 810, Fair value measurements: Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date in the principal or most advantageous market. The Company uses a fair value hierarchy that has three Level 1 – quoted prices (unadjusted) in active markets for identical assets or liabilities; Level 2 – observable inputs other than Level 1, not Level 3 – assets and liabilities whose significant value drivers are unobservable. Observable inputs are based on market data obtained from independent sources, while unobservable inputs are based on the Company ’s market assumptions. Unobservable inputs require significant management judgment or estimation. In some cases, the inputs used to measure an asset or liability may The fair value of cash and accounts payable approximates their carrying amounts due to their short-term maturities. The fair value of the loan payable is indeterminable at this time due to the nature of the arrangement with a state agency and the fact that it is in default. approximates its carrying amount as it bears interest at rates commensurate with market rates. The fair value of the redeemable preferred stock approximates its carrying value due to the dividends accrued on the preferred stock which are reflected as part of the redemption value. The fair value of the deferred compensation and convertible notes payable - affiliates are not Revenue Recognition: Revenues are generated from the sale of nutrient reduction credits. The Company recognizes revenue from the sale of nutrient credits when there is persuasive evidence that an arrangement exists, when title has passed, the price is fixed or determinable, and collection is reasonably assured. The Company expects that technology license fees will be generated from the licensing of Bion ’s integrated system. The Company anticipates that it will charge its customers a non-refundable up-front technology license fee, which will be recognized over the estimated life of the customer relationship. In addition, any on-going technology license fees will be recognized as earned based upon the performance requirements of the agreement. Annual waste treatment fees will be recognized upon receipt. Revenues, if any, from the Company’s interest in Integrated Projects will be recognized when the entity in which the Integrated Project has been developed recognizes such revenue. Stock-based compensation: The Company recognizes the cost of employee services received in exchange for an award of equity instruments in the financial statements and the cost is measured based on the grant date fair value of the award. The stock option compensation expense is recognized over the period during which an employee is required to provide service in exchange for the award (the requisite service period). The Company utilizes the Black-Scholes option-pricing model to determine fair value. Key assumptions of the Black-Scholes option-pricing model include applicable volatility rates, risk-free interest rates and the instrument’s expected remaining life. These assumptions require significant management judgment. Income taxes: The Company recognizes deferred tax assets and liabilities for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their tax bases, as well as net operating losses. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets or liabilities of a change in tax rates is recognized in the period in which the tax change occurs. A valuation allowance is provided to reduce the deferred tax assets by 100%, not not The Company is no 2009. not ’s unrecognized tax positions over the next 12 The Company's policy is to recognize interest and penalties accrued on any unrecognized tax benefits as a component of income tax expense. As of June 30, 2017, no June 30, 2017 2016. Loss per share: Basic loss per share amounts are calculated using the weighted average number of shares of common stock outstanding during the period. Diluted loss per share assumes the conversion, exercise or issuance of all potential common stock instruments, such as options or warrants, unless the effect is to reduce the loss per share. During years ended June 30, 2017 2016, The following table represents the warrants, options and convertible securities excluded from the calculation of diluted loss per share: June 30, 2017 June 30, 2016 Warrants 8,588,729 8,112,114 Options 4,545,037 4,225,537 Convertible debt 9,115,428 7,988,445 Convertible preferred stock 16,000 15,000 The following is a reconciliation of the denominators of the basic loss per share computations for the years ended June 30, 2017 2016: Year ended June 30, 2017 Year ended June 30, 2016 Shares issued – beginning of period 23,573,057 22,089,650 Shares held by subsidiaries (Note 7) (704,309 ) (704,309 ) Shares outstanding – beginning of period 22,868,748 21,385,341 Weighted average shares for fully vested stock bonuses 177,534 600,000 Weighted average shares issued during the period 413,649 759,940 Basic weighted average shares – end of period 23,459,931 22,745,281 Use of estimates: In preparing the Company ’s consolidated financial statements in conformity with accounting principles generally accepted in the United States of America, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Recent Accounting Pronouncements: The Company continually assesses any new accounting pronouncements to determine their applicability. When it is determined that a new accounting pronouncement affects the Company ’s financial reporting, the Company undertakes a study to determine the consequences of the change to its financial statements and assures that there are proper controls in place to ascertain that the Company’s financial statements properly reflect the change.

Revenue Recognition, Policy [Policy Text Block]	Revenue Recognition: Revenues are generated from the sale of nutrient reduction credits. The Company recognizes revenue from the sale of nutrient credits when there is persuasive evidence that an arrangement exists, when title has passed, the price is fixed or determinable, and collection is reasonably assured. The Company expects that technology license fees will be generated from the licensing of Bion ’s integrated system.

Key assumptions of the Black-Scholes option-pricing model include applicable volatility rates, risk-free interest rates and the instrument’s expected remaining life. These assumptions require significant management judgment.
Income Tax, Policy [Policy Text Block]	Income taxes: The Company recognizes deferred tax assets and liabilities for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their tax bases, as well as net operating losses. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled.
