Inventory Disclosure [Abstract]  
Inventory, Policy

The Company's inventories primarily consist of ferrous and non-ferrous scrap metals, and are valued at the lower of average purchased cost or net realizable value ("NRV") based on the specific scrap commodity. Quantities of inventories are determined based on the Company's inventory systems and are subject to periodic physical verification using estimation techniques including observation, weighing and other industry methods. The Company recognizes inventory impairment and related adjustments when the NRV, based upon current market pricing, falls below recorded value or when the estimated volume is less than the recorded volume of the inventory. The Company records the loss in cost of sales in the period during which the loss is identified.
