Summary of Significant Accounting Policies Principles of Presentation and Consolidation The condensed consolidated financial statements included herein have been prepared by us without audit pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”) and should be read in conjunction with our audited financial statements for the year ended December 31, 2018. Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) have 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. The accompanying condensed consolidated financial statements reflect, in our opinion, all normal recurring adjustments necessary to present fairly our financial position at June 30, 2019 and the results of our operations and cash flows for the periods presented. We derived the December 31, 2018 condensed consolidated balance sheet data from audited financial statements; however, we did not include all disclosures required by GAAP. As QRHC, Quest, LDI, Youchange, QVC, QV One, and QSS each operate as environmental-based service companies, we did not deem segment reporting necessary. All intercompany accounts and transactions have been eliminated in consolidation. Interim results are subject to seasonal variations, and the results of operations for the six months ended June 30, 2019 are not necessarily indicative of the results to be expected for the full year.

Each loan under the ABL Facility bears interest, at our option, at either the Base Rate, as defined in the Citizens Loan Agreement, plus a margin ranging from 1.0% to 1.5% (6.75% as of June 30, 2019), or the LIBOR lending rate for the interest period in effect, plus a margin ranging from 2.0% to 2.5% (4.77% as of June 30, 2019). The maturity date of the ABL Facility is February 24, 2022. We had no borrowings under the equipment loan facility, which were required to be requested no later than February 24, 2019. The ABL Facility contains certain specific financial covenants regarding a minimum liquidity requirement and a minimum fixed charge coverage ratio. In addition, the ABL Facility contains negative covenants limiting, among other things, additional indebtedness, transactions with affiliates, additional liens, sales of assets, dividends, investments and advances, mergers and acquisitions, and other matters customarily restricted in such agreements.

Leases	7. Leases ASU 2016-02 Adoption On January 1, 2019, we adopted ASU 2016-02, Leases (Topic 842) When we have the option to extend the lease term, terminate the lease before the contractual expiration date, or purchase the leased asset, and if it is reasonably certain that we will exercise the option, we consider these options in determining the classification and measurement of the lease. As of December 31, 2018, leases classified as capital leases under ASC 840 were included in Property and equipment, net and represented almost fully depreciated office equipment with a negligible book value. We lease certain equipment to a customer under a lease arrangement that expires in 2020. The capital lease receivable amounts are approximately $30,000 at June 30, 2019, the majority of which is included in Prepaid expenses and other current assets. Balance Sheet Classification The table below presents the lease related assets and liabilities recorded on the balance sheet. Right-of-use assets and related liabilities related to finance leases at June 30, 2019 are de minimis and mature in less than 12 months. June 30, 2019 Operating Leases: Right-of-use operating lease asset: Property and equipment, net and other assets $ 1,872,499 Lease Liabilities: Accounts payable and accrued liabilities $ 609,304 Other long-term liabilities 1,452,457 Total operating lease liabilities $ 2,061,761 Lease Costs For the three and six months ended June 30, 2019, we recorded approximately $150,000 and $300,000 of fixed cost operating lease expense, respectively. Our operating lease expense is offset by a minimum annual incentive received from a local Economic Development Council, which is accrued monthly and will continue over the term of the lease through August 2022. This minimum annual incentive is $63,000, which will increase to $93,600 for the annual incentive period starting September 2020. Cash paid for operating leases approximated operating lease expense and non-cash right of use asset amortization for the three and six months ended June 30, 2019. We did not obtain any new operating lease right-of-use assets in the six months ended June 30, 2019. Other Information Our office lease had a remaining term of 3.25 years as of June 30, 2019, and we used an effective interest rate of 2.456%, which was our incremental borrowing rate in effect at the inception of the lease as our lease does not provide a readily determinable implicit rate. The future minimum lease payments required under our office lease as of June 30, 2019 were as follows: Year Ending December 31, Amount 2019 $ 321,120 2020 664,200 2021 664,200 2022 498,150 Total lease payments 2,147,670 Less: Interest 85,909 Present value of lease liabilities $ 2,061,761

Revenue From Contract With Customer [Abstract]
Revenue	8. Revenue Operating Revenues We provide businesses with services to reuse, recycle, and dispose of a wide variety of waste streams and recyclables generated by their operations. In addition, we have product sales and other revenue primarily from sales of products, such as antifreeze and windshield washer fluid, as well as minor ancillary services. Revenue Recognition We recognize revenue as services are performed or products are delivered. For example, we recognize revenue as waste and recyclable material are collected or when products are delivered. We recognize revenue net of any contracted pricing discounts or rebate arrangements. We generally recognize revenue for the gross amount of consideration received as we are generally the primary obligor (or principal) in our contracts with customers as we hold complete responsibility to the customer for contract fulfillment. We record amounts collected from customers for sales tax on a net basis. Disaggregation of Revenue The following table presents our revenue disaggregated by source. Sales and usage-based taxes are excluded from revenue. Three customers accounted for 54.1% of revenue for the three months ended June 30, 2019, and three customers accounted for 53.0% of revenue for the three months ended June 30, 2018. Three customers accounted for 57.0% of revenue for the six months ended June 30, 2019, and three customers accounted for 50.8% of revenue for the six months ended June 30, 2018. We operate primarily in the United States, with minor services in Canada.

We classify our contract acquisition costs as current or noncurrent based on the timing of when we expect to recognize the amortization and are included in other assets. As of June 30, 2019 and December 31, 2018, we had $121,250 and $7,448, respectively, of deferred contract costs. During the three months ended June 30, 2019, we amortized $53,750 and nil of deferred contract costs to selling, general, and administrative expense and as a reduction to revenue, respectively. During the three months ended June 30, 2018, we amortized $70,417 and $18,070 of deferred contract costs to selling, general, and administrative expense and as a reduction to income, respectively. During the six months ended June 30, 2019, we amortized $107,500, and nil of deferred contract costs to selling, general, and administrative expense and as a reduction to income, respectively. During the six months ended June 30, 2018, we amortized $103,750 and $36,139 of deferred contract costs to selling, general, and administrative expense and as a reduction to income, respectively. We bill certain customers in advance, and, accordingly, we defer recognition of related revenues as a contract liability until the services are provided and control is transferred to the customer. As of June 30, 2019 and December 31, 2018, we had $22,416 and $69,473, respectively, of deferred revenue, the majority of which was classified in “Deferred revenue and other current liabilities.”

Earnings Per Share [Abstract]
Net Income (Loss) per Share	12. Net Income (Loss) per Share We compute basic net income (loss) per share using the weighted average number of shares of common stock outstanding during the period. We compute diluted net income (loss) per share using the weighted average number of shares of common stock outstanding during the period, adjusted for the dilutive effect of common stock equivalents. In periods where losses are reported, the weighted average number of shares of common stock outstanding excludes common stock equivalents because their inclusion would be anti-dilutive. Dilutive potential common shares consist of the incremental common shares issuable upon the exercise of outstanding stock options. Dilutive potential securities are excluded from the computation of earnings per share if their effect is antidilutive. The dilutive effect of outstanding stock options and warrants is reflected in diluted earnings per share by application of the treasury stock method. The computation of basic and diluted net income (loss) per share attributable to common stockholders is as follows: Three Months Ended June 30, Six Months Ended June 30, 2019 2018 2019 2018 (Unaudited) (Unaudited) Numerator: Net income (loss) applicable to common stockholders $ 27,102 $ (538,542 ) $ (136,650 ) $ (1,851,061 ) Denominator: Weighted average common shares outstanding, basic 15,339,743 15,307,859 15,334,397 15,305,172 Effect of dilutive common shares 22,663 — — — Weighted average common shares outstanding, diluted 15,362,406 15,307,859 15,334,397 15,305,172 Net income (loss) per share: Basic $ 0.00 $ (0.04 ) $ (0.01 ) $ (0.12 ) Diluted $ 0.00 $ (0.04 ) $ (0.01 ) $ (0.12 ) Anti-dilutive securities excluded from diluted net income (loss) per share: Stock options 2,690,293 1,753,816 2,712,956 1,753,816 Warrants 1,733,565 1,733,565 1,733,565 1,733,565 Total anti-dilutive securities excluded from net income (loss) per share 4,423,858 3,487,381 4,446,521 3,487,381

Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) have 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. The accompanying condensed consolidated financial statements reflect, in our opinion, all normal recurring adjustments necessary to present fairly our financial position at June 30, 2019 and the results of our operations and cash flows for the periods presented. We derived the December 31, 2018 condensed consolidated balance sheet data from audited financial statements; however, we did not include all disclosures required by GAAP. As QRHC, Quest, LDI, Youchange, QVC, QV One, and QSS each operate as environmental-based service companies, we did not deem segment reporting necessary. All intercompany accounts and transactions have been eliminated in consolidation. Interim results are subject to seasonal variations, and the results of operations for the six months ended June 30, 2019 are not necessarily indicative of the results to be expected for the full year.
