Accounting Policies [Abstract]
Revenue Recognition and Deferred Revenue	Revenue Recognition and Deferred Revenue S-K Environmental Services revenue is generated from providing parts cleaning services, containerized waste services, oil collection services and other complementary products and services. Parts cleaning services generally consist of placing a specially designed parts washer at a customer's premises and then, on a recurring basis, delivering clean solvent or aqueous-based washing fluid, cleaning and servicing the parts washer and removing the used solvent or aqueous fluid. The Company also services customer-owned parts washers. Revenue from parts cleaning services is recognized over the service interval. Service intervals represent the actual amount of time between service visits to a particular parts cleaning customer. Average service intervals vary from seven to 14 weeks depending on several factors, such as customer accommodation, types of machines serviced and frequency of use. Containerized waste services consist of profiling, collecting, transporting and recycling or disposing of a wide variety of hazardous and non-hazardous wastes. Revenue is recognized upon disposal. The Company tracks the amount of time it takes from collection of the customer's waste to delivery to the disposal outlet, which represents a deferral period of approximately two and one-half weeks. Other complementary products and services include vacuum services, allied products and other environmental services. Revenue is recognized when products are delivered and services are performed. Oil Re-refining and Recycling revenue is generated from re-refining used oil to produce high quality base and blended lubricating oils, and recycling used oil collected in excess of the Company's re-refining capacity into recycled fuel oil. The high quality base and blended lubricating oils are sold to third-party distributors, retailers, government agencies, fleets, railroads and industrial customers. The recycled fuel oil is sold to asphalt plants, industrial plants, blenders, pulp and paper companies, vacuum gas oil producers and marine diesel oil producers. Revenue is recognized upon delivery.
Deferred Costs Relating to Deferred Revenue	Deferred Costs Relating to Deferred Revenue Commissions and other incremental direct costs, primarily costs of materials and transportation expenses, relating to deferred revenue from the Company’s parts cleaning services, containerized waste services and vacuum services are capitalized and deferred. The deferred costs are included in current assets in the consolidated balance sheet and expensed when the related revenues are recognized.
Recent Accounting Pronouncements	Recent Accounting Pronouncements In July 2013, the Financial Accounting Standards Board (“FASB”) issued ASU 2013-11 Income Taxes (Topic 740) - Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists. This standard provides guidance regarding when an unrecognized tax benefit should be classified as a reduction to a deferred tax asset or when it should be classified as a liability in the consolidated balance sheet. The guidance is effective for the Company on January 1, 2014. Management does not expect the adoption of this standard to have a significant impact on the Company's consolidated balance sheets. In February 2013, the FASB issued ASU 2013-02 Comprehensive Income (Topic 220) - Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income. The new guidance requires an entity to provide information about the amounts reclassified out of accumulated other comprehensive income (“AOCI”) by component. Entities are required to present, either on the face of the income statement where net income is presented or in the notes, significant amounts reclassified out of AOCI by respective line items of net income if the amount reclassified is required under U.S. GAAP to be reclassified to net income in its entirety in the same reporting period. For other amounts that are not required to be reclassified in their entirety to net income, entities are required to cross-reference the disclosures required under U.S. GAAP that provide additional detail about those amounts. This guidance is effective prospectively for annual and interim reporting periods beginning after December 31, 2012. The Company adopted the standard on January 1, 2013. The amounts required to be disclosed under this guidance are disclosed in Note 14, “Accumulated Other Comprehensive Income.”

Disclosure of accounting policy for revenue recognition. If the entity has different policies for different types of revenue transactions, the policy for each material type of transaction is generally disclosed. If a sales transaction has multiple element arrangements (for example, delivery of multiple products, services or the rights to use assets) the disclosure may indicate the accounting policy for each unit of accounting as well as how units of accounting are determined and valued. The disclosure may encompass important judgment as to appropriateness of principles related to recognition of revenue. The disclosure also may indicate the entity's treatment of any unearned or deferred revenue that arises from the transaction.
