Which statement best describes F-listed wastes and K-listed wastes?

Which statement best describes F-listed wastes and K-listed wastes?

• A. F-listed wastes are household wastes; K-listed wastes are only from pharmaceutical industries.
• B. F-listed wastes are municipal solid wastes; K-listed wastes are industrial process residues.
• C. F-listed wastes are non-specific source wastes, such as solvents; K-listed wastes are source-specific wastes from particular industries.
• D. F-listed wastes are recyclable wastes; K-listed wastes are non-recyclable.

Answer: (C)

The main idea is how the listing categories classify waste by its origin. F-listed wastes are non-specific source wastes, meaning they come from common industrial processes and broad use of solvents—things that can occur in many different facilities. K-listed wastes, on the other hand, are source-specific wastes tied to particular industries and their specific processes. So describing F-listed wastes as non-specific source wastes (such as solvents) and K-listed wastes as source-specific wastes from particular industries accurately reflects how the lists are organized. The other statements misstate these distinctions, for example by labeling F-lists as household or municipal wastes or recyclable, or by limiting K-lists to pharmaceutical sources.
