What is a principal recyclable material?
The principal recyclable material is the one that occurs in the largest quantity (by weight) in a property’s waste stream. It typically varies by business type. For example, in an office building, the principal recyclable is usually mixed paper. For retail stores, warehouses or food service operations, it tends to be corrugated cardboard and/or mixed paper; for auto repair and maintenance, it may be scrap metal or used oil; and for landscapers, it is usually leaves, brush and other yard waste.
