K-listed wastes come from which sources?

• A. Specific industries
• B. Household waste
• C. Radioactive sources
• D. Consumer products

Answer: (A)

K-listed wastes are identified by the specific industries that generate them. This category targets industrial waste streams that come from particular sectors, such as wood preserving, petroleum refining, coke production, pigment manufacturing, and similar processes. The focus is on where the waste comes from in the industrial system, not on household waste, radioactive material, or general consumer products.

Household waste is not described by the K-list because it doesn't arise from defined industrial processes. Radioactive sources are governed by separate nuclear/radiation safety regulations, not by the K-list. While some consumer products can become hazardous waste when discarded, the K-list specifically classifies wastes by the industry that generates them, not by the product type.
