Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization and Nature of Operations	ORGANIZATION AND NATURE OF OPERATIONS Heritage-Crystal Clean, Inc., a Delaware corporation and its subsidiaries (collectively the “Company”), provides parts cleaning and hazardous and non-hazardous waste services to small and mid-sized customers in both the manufacturing and vehicle maintenance sectors. The Company's service programs include parts cleaning, containerized waste management, used oil collection, vacuum truck services, waste antifreeze collection and recycling, and field services. The Company also owns and operates a used oil re-refinery through which it recycles used oil into high quality base oil for lubricants as well as other re-refinery byproducts. The Company also has multiple locations where it dehydrates used oil to be sold as recycled fuel oil. The Company's locations are in the United States and Ontario, Canada. The Company conducts its primary business operations through Heritage-Crystal Clean, LLC, its wholly owned subsidiary, and all intercompany balances have been eliminated in consolidation. The Company’s fiscal year ends on the Saturday closest to December 31. The most recent fiscal year ended on January 3, 2015 . Each of the Company's first three fiscal quarters consists of twelve weeks while the last fiscal quarter consists of sixteen or seventeen weeks. In the Company's Environmental Services segment, product revenues include sales of solvent, machines, antifreeze, and accessories; and service revenues include drum waste removal services, servicing of parts cleaning machines, vacuum truck services, field services, and other services. In the Company's Oil Business segment, product revenues include sales of re-refined base oil, byproducts, recycled fuel oil, and used oil; and service revenues include revenues from collecting and disposing of waste water. Due to the Company's integrated business model, it is impracticable to separately present costs of tangible products and costs of services.

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES The Company's significant accounting policies are described in Note 2, "Summary of Significant Accounting Policies," in the Company's Annual Report on Form 10-K for the fiscal year ended January 3, 2015. There have been no material changes in these policies or their application. The Company tests goodwill for impairment annually in the fourth quarter and in interim periods if changes in circumstances indicate that the carrying value of goodwill may not be recoverable. The Company tests goodwill for impairment at each of its two reporting units, Environmental Services and Oil Business, both of which have goodwill. We do not aggregate reporting units for purposes of impairment testing. In fiscal 2014, the fair value of the Environmental Services reporting unit was substantially in excess of its carrying value. The fair value of the Oil Business reporting unit exceeded its carrying value by approximately 8.7 percent. There is a moderate degree of uncertainty associated with key Oil Business fair value assumptions such as the selling price of re-refined oil products and byproducts, the price paid/(charged) for raw material inputs such as used oil, operating efficiency of the used oil re-refinery, etc. A contraction of the spread between the selling price of lubricating base oil and the price paid/(charged) to vendors for raw material inputs could reasonably be expected to negatively affect the key assumptions used to determine fair value. Recently Issued Accounting Pronouncements In May 2014, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update No. 2014-09, Revenue from Contracts with Customers (Topic 606) (ASU 2014-09). ASU 2014-09 outlines a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance, including industry-specific guidance. This new guidance is effective for annual reporting periods (including interim reporting periods within those periods) beginning after December 15, 2016. Entities have the option of using either a full retrospective or a modified approach to adopt the guidance. This update could impact the timing and amounts of revenue recognized. The Company is currently evaluating the effect that implementation of this update will have on its consolidated financial position and results of operations upon adoption. In April 2015, the FASB issued ASU No. 2015-03, Interest - Imputation of Interest (Subtopic 835-30) - Simplifying the Presentation of Debt Issuance Costs . ASU 2015-03 requires companies to present debt issuance costs on the balance sheet as a direct deduction from the debt liability in a manner consistent with the Company's accounting treatment of debt discounts. The changes are to be applied retrospectively to all periods presented beginning in annual periods beginning after December 15, 2015, and early adoption is permitted. The Company expects to reflect these changes in presentation of debt issuance costs beginning in the first quarter of fiscal 2016. The Company expects the adoption of ASU 2015-03 will decrease Other Current Assets by $1.4 million and decrease Long Term Debt by $1.4 million . In September 2015, the FASB issued ASU No. 2015-16, Business Combinations (Topic 805): Simplifying the Accounting for Measurement-Period Adjustments (ASU 2015-16). ASU No. 2015-16 simplifies the accounting for measurement-period adjustments in a business combination by requiring the acquirer to recognize adjustments to provisional amounts identified during the measurement period in the reporting period in which the adjustments are determined. The acquirer is also required to record in the reporting period in which the adjustments are determined the effect on earnings of changes in depreciation, amortization, and other items resulting from the change to the provisional amounts. The new guidance is effective for fiscal years beginning after December 15, 2015, including interim periods within those fiscal years. The Company is currently evaluating the effect that implementation of this update will have on its consolidated financial position and results of operations upon adoption.

Business Combinations [Abstract]
Business Combinations	BUSINESS COMBINATIONS On October 16, 2014, the Company purchased the outstanding stock of FCC Environmental LLC, a Delaware limited liability company, and International Petroleum Corp. of Delaware, a Delaware corporation (together "FCC Environmental"), pursuant to a Stock Purchase Agreement entered into with Dédalo Patrimonial S.L.U., a sociedad limitadad unipersonal formed under the laws of Spain ("Seller"). Prior to the purchase, FCC Environmental was an environmental services provider and collector of used oil in the United States and operated 34 facilities mostly in the eastern half of the United States. The purchase price for FCC Environmental was set at $90.0 million subject to certain adjustments, including, without limitation, a working capital adjustment and indemnification rights and obligations. Based on the initial working capital calculations, the Company initially paid $88.8 million . The Company is in the process of determining the final purchase price, which is based on the final working capital calculations and must be agreed upon by the Seller and the Company. The outcome of the calculation of the working capital adjustment may significantly impact the purchase price and purchase price allocation. The results of FCC Environmental are consolidated into both of the Company's operating segments subsequent to the closing date. The Company is continuing to evaluate the purchase price allocations. Preliminary purchase price allocations are tentative and subject to revision as the Company finalizes appraisals and other analyses. Measurement period adjustments reflect new information obtained about facts and circumstances that existed as of the acquisition date. Final determination of the fair values may result in further adjustments to the values presented. The Company believes that the preliminary allocations provide a reasonable basis for estimating the fair values of assets acquired and liabilities assumed based on the information available. The FCC Environmental purchase price allocation is preliminary as the Company is still in the process of obtaining information to finalize the purchase price, net cash paid, and estimated fair values of the assets and liabilities presented below. The Company expects to finalize the purchase price allocation no later than one year from the purchase date. The following table summarizes the estimated fair values of the assets acquired and liabilities assumed, net of cash acquired, related to the acquisition (in thousands): FCC Environmental Accounts receivable $ 20,430 Inventory 7,899 Other current assets 6,683 Deferred taxes 1,748 Property, plant, & equipment (a)(c) 49,752 Equipment at customers 420 Intangible assets 9,808 Goodwill (b)(c) 13,168 Accounts payable (12,453 ) Accrued salaries, wages, and benefits (2,039 ) Taxes payable (2,209 ) Other current liabilities (1,378 ) Capital lease obligations (a) (5,918 ) Net cash paid $ 85,911 ______________ (a) Subsequent to the closing date, the Company modified the leases acquired from FCC Environmental, resulting in the classification of the leases as Operating leases under the new lease terms. The change in lease terms decreased both Property, plant, & equipment and Capital lease obligations by $5.9 million . (b) Goodwill recognized from the acquisition of FCC Environmental represents the excess of the fair value of the net assets acquired over the purchase price, and is based upon the Company's expectations of synergies from combining the operations of FCC Environmental and the Company, and the value of intangible assets that are not separately recognized, such as the assembled workforce. Goodwill of $7.1 million and $6.1 million were assigned to the Environmental Services and Oil Business segments, respectively. All goodwill is expected to be deductible for income tax purposes. (c) The Company has retrospectively adjusted amounts that were recognized at the acquisition date to reflect new information about the facts and circumstances that existed as of the acquisition date that, if known, would have affected the measurement of the amounts recognized as of that date. These adjustments are related to the Company's valuation of accounts receivable, other current assets, property, plant and equipment, and goodwill acquired. Such adjustments resulted in a net decrease of $1.6 million in accounts receivable, a net decrease of $0.1 million in other current assets, a net decrease of $2.0 million in property, plant and equipment and a net increase of $3.6 million in goodwill. The Company's balance sheet as of January 3, 2015 has been retrospectively restated to reflect these adjustments. Unaudited Pro Forma Financial Information The pro forma financial information in the table below presents the combined results of the Company as if the FCC Environmental acquisition that occurred in fiscal 2014 had occurred December 29, 2013 (in thousands, except per share data).

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	COMMITMENTS AND CONTINGENCIES The Company may enter into purchase obligations with certain vendors. They represent expected payments to third party service providers and other commitments entered into during the normal course of our business. These purchase obligations are generally cancelable with or without notice, without penalty, although certain vendor agreements provide for cancellation fees or penalties depending on the terms of the contract. The Company has purchase obligations in the form of open purchase orders of $16.5 million as of September 12, 2015 , primarily for used oil, solvent, machine purchases, disposal and transportation expenses, and capital expenditures. The Company may be subject to investigations, claims or lawsuits as a result of operating its business, including matters governed by environmental laws and regulations. The Company may also be subject to tax audits in a variety of jurisdictions. When claims are asserted, the Company evaluates the likelihood that a loss will occur and records a liability for those instances when the likelihood is deemed probable and the exposure is reasonably estimable. The Company carries insurance at levels it believes are adequate to cover loss contingencies based on historical claims activity. When the potential loss exposure is limited to the insurance deductible and the likelihood of loss is determined to be probable, the Company accrues for the amount of the required deductible, unless a lower amount of exposure is estimated. As of September 12, 2015 and January 3, 2015 , the Company had accrued $1.6 million and $1.8 million related to loss contingencies and other contingent liabilities, respectively.

Income Taxes

Income Tax Disclosure [Abstract]
Income Taxes	INCOME TAXES The Company deducted for federal income tax purposes accelerated "bonus" depreciation on the majority of its capital expenditures for assets placed in service in fiscal 2011 through fiscal 2014. Therefore, the Company recorded a noncurrent deferred tax liability to reflect difference between the book basis and the tax basis of those assets. In addition, as a result of the federal bonus depreciation, the Company recorded a Net Operating Loss ("NOL") of $44.7 million , which will begin to expire in 2031. The balance remaining on the NOL, which is primarily the result of bonus depreciation, as of September 12, 2015 was $37.0 million , and the remaining deferred tax asset related to the Company's state and federal NOL was a tax effected balance of $12.3 million . The Company recognizes windfall tax benefits associated with the exercise of stock options directly to stockholders' equity only when realized. Consequently, deferred tax assets are not recognized for NOLs resulting from windfall tax benefits. At September 12, 2015 , deferred tax assets do not include $2.5 million of excess tax benefits from share-based compensation. The Company's effective tax rate for the third quarter of fiscal 2015 was 37.3% compared to 44.6% in the third quarter of fiscal 2014 . The rate difference is attributable to non-deductible expenses and certain state taxes not based on income having a lesser effect on the tax rate compared to the third quarter of fiscal 2014. The Company's effective tax rate for the first three quarters of fiscal 2015 was 38.6% compared to 42.1% in the first three quarters of fiscal 2014. The rate decrease is attributable to year-to-date non-deductible expenses having lesser impact the tax rate as compared to the first three quarters of fiscal 2014 due to lower income in the first three quarters of fiscal 2014. The Company establishes reserves when it is more likely than not that the Company will not realize the full tax benefit of a position. The Company had a reserve of $1.9 million for uncertain tax positions as of September 12, 2015 and January 3, 2015 . The gross unrecognized tax benefits would, if recognized, decrease the Company's effective tax rate.

Accounting Policies [Abstract]
Fiscal Period, Policy	The Company’s fiscal year ends on the Saturday closest to December 31. The most recent fiscal year ended on January 3, 2015 . Each of the Company's first three fiscal quarters consists of twelve weeks while the last fiscal quarter consists of sixteen or seventeen weeks.
Recently Issued Accounting Pronouncements	Recently Issued Accounting Pronouncements In May 2014, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update No. 2014-09, Revenue from Contracts with Customers (Topic 606) (ASU 2014-09). ASU 2014-09 outlines a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance, including industry-specific guidance. This new guidance is effective for annual reporting periods (including interim reporting periods within those periods) beginning after December 15, 2016. Entities have the option of using either a full retrospective or a modified approach to adopt the guidance. This update could impact the timing and amounts of revenue recognized. The Company is currently evaluating the effect that implementation of this update will have on its consolidated financial position and results of operations upon adoption. In April 2015, the FASB issued ASU No. 2015-03, Interest - Imputation of Interest (Subtopic 835-30) - Simplifying the Presentation of Debt Issuance Costs . ASU 2015-03 requires companies to present debt issuance costs on the balance sheet as a direct deduction from the debt liability in a manner consistent with the Company's accounting treatment of debt discounts. The changes are to be applied retrospectively to all periods presented beginning in annual periods beginning after December 15, 2015, and early adoption is permitted. The Company expects to reflect these changes in presentation of debt issuance costs beginning in the first quarter of fiscal 2016. The Company expects the adoption of ASU 2015-03 will decrease Other Current Assets by $1.4 million and decrease Long Term Debt by $1.4 million . In September 2015, the FASB issued ASU No. 2015-16, Business Combinations (Topic 805): Simplifying the Accounting for Measurement-Period Adjustments (ASU 2015-16). ASU No. 2015-16 simplifies the accounting for measurement-period adjustments in a business combination by requiring the acquirer to recognize adjustments to provisional amounts identified during the measurement period in the reporting period in which the adjustments are determined. The acquirer is also required to record in the reporting period in which the adjustments are determined the effect on earnings of changes in depreciation, amortization, and other items resulting from the change to the provisional amounts. The new guidance is effective for fiscal years beginning after December 15, 2015, including interim periods within those fiscal years. The Company is currently evaluating the effect that implementation of this update will have on its consolidated financial position and results of operations upon adoption.

Business Combinations [Abstract]
Schedule of Business Acquisitions, by Acquisition	The following table summarizes the estimated fair values of the assets acquired and liabilities assumed, net of cash acquired, related to the acquisition (in thousands): FCC Environmental Accounts receivable $ 20,430 Inventory 7,899 Other current assets 6,683 Deferred taxes 1,748 Property, plant, & equipment (a)(c) 49,752 Equipment at customers 420 Intangible assets 9,808 Goodwill (b)(c) 13,168 Accounts payable (12,453 ) Accrued salaries, wages, and benefits (2,039 ) Taxes payable (2,209 ) Other current liabilities (1,378 ) Capital lease obligations (a) (5,918 ) Net cash paid $ 85,911 ______________ (a) Subsequent to the closing date, the Company modified the leases acquired from FCC Environmental, resulting in the classification of the leases as Operating leases under the new lease terms. The change in lease terms decreased both Property, plant, & equipment and Capital lease obligations by $5.9 million . (b) Goodwill recognized from the acquisition of FCC Environmental represents the excess of the fair value of the net assets acquired over the purchase price, and is based upon the Company's expectations of synergies from combining the operations of FCC Environmental and the Company, and the value of intangible assets that are not separately recognized, such as the assembled workforce. Goodwill of $7.1 million and $6.1 million were assigned to the Environmental Services and Oil Business segments, respectively. All goodwill is expected to be deductible for income tax purposes. (c) The Company has retrospectively adjusted amounts that were recognized at the acquisition date to reflect new information about the facts and circumstances that existed as of the acquisition date that, if known, would have affected the measurement of the amounts recognized as of that date. These adjustments are related to the Company's valuation of accounts receivable, other current assets, property, plant and equipment, and goodwill acquired. Such adjustments resulted in a net decrease of $1.6 million in accounts receivable, a net decrease of $0.1 million in other current assets, a net decrease of $2.0 million in property, plant and equipment and a net increase of $3.6 million in goodwill. The Company's balance sheet as of January 3, 2015 has been retrospectively restated to reflect these adjustments.

[1]	Subsequent to the closing date, the Company modified the leases acquired from FCC Environmental, resulting in the classification of the leases as Operating leases under the new lease terms. The change in lease terms decreased both Property, plant, & equipment and Capital lease obligations by $5.9 million.
[2]	The Company has retrospectively adjusted amounts that were recognized at the acquisition date to reflect new information about the facts and circumstances that existed as of the acquisition date that, if known, would have affected the measurement of the amounts recognized as of that date. These adjustments are related to the Company's valuation of accounts receivable, other current assets, property, plant and equipment, and goodwill acquired. Such adjustments resulted in a net decrease of $1.6 million in accounts receivable, a net decrease of $0.1 million in other current assets, a net decrease of $2.0 million in property, plant and equipment and a net increase of $3.6 million in goodwill. The Company's balance sheet as of January 3, 2015 has been retrospectively restated to reflect these adjustments.
[3]	Goodwill recognized from the acquisition of FCC Environmental represents the excess of the fair value of the net assets acquired over the purchase price, and is based upon the Company's expectations of synergies from combining the operations of FCC Environmental and the Company, and the value of intangible assets that are not separately recognized, such as the assembled workforce. Goodwill of $7.1 million and $6.1 million were assigned to the Environmental Services and Oil Business segments, respectively. All goodwill is expected to be deductible for income tax purposes.
