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, 2017. 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 March 31, 2018 and the results of our operations and cash flows for the periods presented. We derived the December 31, 2017 condensed consolidated balance sheet data from audited financial statements; however, we did not include all disclosures required by GAAP. As 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 three months ended March 31, 2018 are not necessarily indicative of the results to be expected for the full year.

Net Loss Per Share

We compute basic net loss per share by dividing net loss applicable to common stockholders by the weighted average number of shares of common stock outstanding during the period. We have other potentially dilutive securities outstanding that are not shown in a diluted net loss per share calculation because their effect in both 2018 and 2017 would be anti-dilutive. These potentially dilutive securities include stock options and warrants and totaled 3,497,424 and 3,313,907 shares at March 31, 2018 and 2017, respectively.

The following table sets forth the anti-dilutive securities excluded from diluted loss per share:

Recent Accounting Pronouncements

Adopted

In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2014-09, Revenue from Contracts with Customers (Topic 606). On January 1, 2018, we adopted ASU 2014-09 using the full retrospective approach for all ongoing customer contracts. There was no impact to our financial statements as a result of adopting Topic 606 for the three months ended March 31, 2018 and 2017. See Note 8 for additional information and disclosures related to this amended guidance.

Pending Adoption

In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842). The update improves financial reporting about leasing transactions by requiring a lessee to record on the balance sheet the assets and liabilities for the rights and obligations created by lease terms of more than 12 months. ASU 2016-02 is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. We are still evaluating the impact of adopting ASU 2016-02 on our consolidated financial statements. However, given the material amount of our future minimum payments under non-cancellable operating leases, primarily office rent, at March 31, 2018, we expect to recognize a material right-of-use lease asset and lease liability upon adoption of the ASU.

In June 2016, the FASB issued ASU 2016-13, Financial Instruments – Credit Losses (Topic 326), which provides guidance on measuring credit losses on financial instruments. The amended guidance replaces current incurred loss impairment methodology of recognizing credit losses when a loss is probable with a methodology that reflects expected credit losses and requires a broader range of reasonable and supportable information to assess credit loss estimates. ASU 2016-13 is effective for us on January 1, 2020, with early adoption permitted on January 1, 2019. We are assessing the provisions of this amended guidance; however, the adoption of the standard is not expected to have a material effect on our consolidated financial statements.

There have been no other recent accounting pronouncements or changes in accounting pronouncements that have been issued but not yet adopted that are of significance, or potential significance to us.

Security deposits and other assets		481,275		363,475
Property and equipment, net, and other assets	$	1,344,199	$	1,320,342

We compute depreciation using the straight-line method over the estimated useful lives of the property and equipment. Depreciation expense for the three months ended March 31, 2018 was $103,310, inclusive of $45,296 of depreciation expense reflected within “Cost of revenue” in our condensed consolidated statement of operations as it related to assets used in directly servicing customer contracts. Depreciation expense for the three months ended March 31, 2017 was $115,246, inclusive of $41,075 of depreciation expense reflected within “Cost of revenue.” At March 31, 2018, the carrying value of our capital lease assets was $217,729, net of $282,368 of accumulated depreciation. At December 31, 2017, the carrying value of our capital lease assets was $243,778, net of $256,319 of accumulated depreciation.

On February 20, 2018 (“Closing Date”), we entered into an Asset Purchase Agreement with Earth Media Partners, LLC to sell certain assets of our wholly owned subsidiary, Earth911, Inc., in exchange for a 19% interest in Earth Media Partners, LLC, which was recorded as an investment in the amount of $246,585 as of the Closing Date, and a potential future earn-out amount of approximately $350,000. The net assets sold related to the Earth911.com website business and consisted primarily of the website and its content and customers, deferred revenues, and accounts receivable as of the Closing Date. Earth911, Inc. was subsequently renamed Quest Sustainability Services, Inc. In addition to our investment in Earth Media Partners, LLC, we accrued a receivable in the amount of $8,086 related to the earn-out as of March 31, 2018. The carrying amount of our investment and the accrued earn-out receivable are included in other assets.

Revolving Credit Facility	6. Revolving Credit Facility We entered into a Loan, Security and Guaranty Agreement (the “Citizens Loan Agreement”), dated as of February 24, 2017, with Citizens Bank, National Association as a lender, and as administrative agent, collateral agent, and issuing bank, which provides for an asset-based revolving credit facility (the “ABL Facility”) of up to $20 million and an equipment loan facility in the maximum principal amount of $2.0 million. Each loan under the ABL Facility bears interest, at our option, at either the Base Rate, as defined in the agreement, plus a margin ranging from 1.0% to 1.5% (6.25% as of March 31, 2018), or the LIBOR lending rate for the interest period in effect, plus a margin ranging from 2.0% to 2.5% (4.28% as of March 31, 2018). The maturity date of the revolving credit facility is February 24, 2022. Loans under the equipment loan facility may be requested at any time until February 24, 2019. Each loan under the equipment loan facility bears interest, at our option, at either the Base Rate, as defined in the agreement, plus 2.00%, or the LIBOR lending rate for the interest period in effect, plus 3.00%. The maturity date of the equipment loan facility is February 24, 2022. The ABL Facility contains certain specific financial covenants regarding a minimum liquidity requirement and a minimum fixed charge coverage ratio. The minimum fixed charge coverage ratio covenant applies commencing May 15, 2018, when the trailing 12-month period ending March 31, 2018 is reported. 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. The amount of interest expense related to borrowings for the three months ended March 31, 2018 and 2017 was $84,288 and $110,381, respectively. Debt issuance cost of $469,507 is being amortized to interest expense over the life of the new revolving credit facility beginning March 1, 2017. As of March 31, 2018, the unamortized portion of the debt issuance costs was $367,781. The amount of interest expense related to the amortization of the discount on the revolving credit facility for the three months ended March 31, 2018 was $23,475. As of March 31, 2018, the ABL Facility borrowing base availability was $11,545,000 and the outstanding liability was $5,100,957, net of unamortized debt issuance cost of $367,781. There were no draws made on the equipment loan facility as of March 31, 2018.

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, revenue is recognized as waste and recyclable material is collected or when products are delivered.

We generally recognize revenues 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 previously had a contract accounted for as a net basis management fee contract, with revenue of $44,088 and gross billings of $1,294,459 for the three months ended March 31, 2017. This management fee contract ended in the second quarter of 2017, and we currently have no other net basis contracts.

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 48.4% of revenue for the three months ended March 31, 2018, and two customers accounted for 55.1% of revenue for the three months ended March 31, 2017. We operate primarily in the United States, with minor services in Canada.

Contract Balances

Our incremental direct costs of obtaining a customer contract are generally deferred and amortized to selling, general, and administrative expense or as a reduction to revenue (depending on the nature of the cost) over the estimated life of the customer contract. Our contract acquisition costs are classified as current or noncurrent based on the timing of when we expect to recognize the amortization and are included in other assets.

As of March 31, 2018 and December 31, 2017, we had $199,736 and $136,139, respectively, of deferred contract costs. During the three months ended March 31, 2018, we amortized $33,333 and $18,069 of deferred contract costs to selling, general, and administrative expense and as a reduction to income, respectively. During the three months ended March 31, 2017, we amortized $100,000 and $18,069 of deferred contract costs to selling, general and administrative expense and as a reduction to income, respectively.

Certain customers are billed in advance, and, accordingly, recognition of related revenues is deferred as a contract liability until the services are provided and control transferred to the customer. As of March 31, 2018 and December 31, 2017, we had $142,389 and $309,089, respectively, of deferred revenue, the majority of which was classified in “Deferred revenue and other current liabilities.”

Income Taxes	3 Months Ended
Income Taxes	Mar. 31, 2018
Income Tax Disclosure [Abstract]
Income Taxes	9. Income Taxes We compute income taxes using the asset and liability method in accordance with FASB ASC Topic 740, Income Taxes. Under the asset and liability method, we determine deferred income tax assets and liabilities based on the differences between the financial reporting and tax bases of assets and liabilities and measure them using currently enacted tax rates and laws. We provide a valuation allowance for the amount of deferred tax assets that, based on available evidence, are more likely than not to be realized. Realization of our net operating loss carryforward was not reasonably assured as of March 31, 2018 and December 31, 2017, and we have recorded a valuation allowance of $12,800,000 and $12,150,000, respectively, against deferred tax assets in excess of deferred tax liabilities in the accompanying condensed consolidated financial statements. As of March 31, 2018 and December 31, 2017, we had federal income tax net operating loss carryforwards of approximately $20,200,000 and $19,700,000, respectively, which expire at various dates beginning in 2031. On December 22, 2017, The Tax Cuts and Jobs Act (the “2017 Act”) was enacted. The most significant impact to us of the 2017 Act was a decrease in the federal corporate income tax rate from 35% to 21% starting in 2018.

Fair Value of Financial Instruments	Mar. 31, 2018
Fair Value Disclosures [Abstract]
Fair Value of Financial Instruments	10. Fair Value of Financial Instruments Our financial instruments consist of cash and cash equivalents, accounts receivable, accounts payable, accrued liabilities, deferred revenue, revolving credit facility, and capital lease obligations. We do not believe that we are exposed to significant interest, currency, or credit risks arising from these financial instruments. The fair values of these financial instruments approximate their carrying values using Level 3 inputs, based on their short maturities or, for long-term portions of capital lease obligations and revolving credit facility, based on borrowing rates currently available to us for loans with similar terms and maturities.

- Definition

The entire disclosure for the fair value of financial instruments (as defined), including financial assets and financial liabilities (collectively, as defined), and the measurements of those instruments as well as disclosures related to the fair value of non-financial assets and liabilities. Such disclosures about the financial instruments, assets, and liabilities would include: (1) the fair value of the required items together with their carrying amounts (as appropriate); (2) for items for which it is not practicable to estimate fair value, disclosure would include: (a) information pertinent to estimating fair value (including, carrying amount, effective interest rate, and maturity, and (b) the reasons why it is not practicable to estimate fair value; (3) significant concentrations of credit risk including: (a) information about the activity, region, or economic characteristics identifying a concentration, (b) the maximum amount of loss the entity is exposed to based on the gross fair value of the related item, (c) policy for requiring collateral or other security and information as to accessing such collateral or security, and (d) the nature and brief description of such collateral or security; (4) quantitative information about market risks and how such risks are managed; (5) for items measured on both a recurring and nonrecurring basis information regarding the inputs used to develop the fair value measurement; and (6) for items presented in the financial statement for which fair value measurement is elected: (a) information necessary to understand the reasons for the election, (b) discussion of the effect of fair value changes on earnings, (c) a description of [similar groups] items for which the election is made and the relation thereof to the balance sheet, the aggregate carrying value of items included in the balance sheet that are not eligible for the election; (7) all other required (as defined) and desired information.

Accounting Policies [Abstract]

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, 2017. 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 March 31, 2018 and the results of our operations and cash flows for the periods presented. We derived the December 31, 2017 condensed consolidated balance sheet data from audited financial statements; however, we did not include all disclosures required by GAAP. As 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 three months ended March 31, 2018 are not necessarily indicative of the results to be expected for the full year.

Net Loss Per Share

We compute basic net loss per share by dividing net loss applicable to common stockholders by the weighted average number of shares of common stock outstanding during the period. We have other potentially dilutive securities outstanding that are not shown in a diluted net loss per share calculation because their effect in both 2018 and 2017 would be anti-dilutive. These potentially dilutive securities include stock options and warrants and totaled 3,497,424 and 3,313,907 shares at March 31, 2018 and 2017, respectively.

The following table sets forth the anti-dilutive securities excluded from diluted loss per share:

Recent Accounting Pronouncements

Adopted

In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2014-09, Revenue from Contracts with Customers (Topic 606). On January 1, 2018, we adopted ASU 2014-09 using the full retrospective approach for all ongoing customer contracts. There was no impact to our financial statements as a result of adopting Topic 606 for the three months ended March 31, 2018 and 2017. See Note 8 for additional information and disclosures related to this amended guidance.

Pending Adoption

In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842). The update improves financial reporting about leasing transactions by requiring a lessee to record on the balance sheet the assets and liabilities for the rights and obligations created by lease terms of more than 12 months. ASU 2016-02 is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. We are still evaluating the impact of adopting ASU 2016-02 on our consolidated financial statements. However, given the material amount of our future minimum payments under non-cancellable operating leases, primarily office rent, at March 31, 2018, we expect to recognize a material right-of-use lease asset and lease liability upon adoption of the ASU.

In June 2016, the FASB issued ASU 2016-13, Financial Instruments – Credit Losses (Topic 326), which provides guidance on measuring credit losses on financial instruments. The amended guidance replaces current incurred loss impairment methodology of recognizing credit losses when a loss is probable with a methodology that reflects expected credit losses and requires a broader range of reasonable and supportable information to assess credit loss estimates. ASU 2016-13 is effective for us on January 1, 2020, with early adoption permitted on January 1, 2019. We are assessing the provisions of this amended guidance; however, the adoption of the standard is not expected to have a material effect on our consolidated financial statements.

There have been no other recent accounting pronouncements or changes in accounting pronouncements that have been issued but not yet adopted that are of significance, or potential significance to us.
