These are any waste materials that can be retrieved from the waste stream and free from contamination that can still be converted into suitable beneficial use.

• A. Special wastes
• B. Recyclable wastes
• C. Residual wastes
• D. Compostable wastes

Answer: (B)

Recyclable wastes are materials that can be recovered from the waste stream and converted into new products, provided they are clean enough to be processed. The emphasis is on recoverability and the ability to be reused through recycling processes like sorting, cleaning, and remanufacturing. When wastes are free from contamination, they can move into the recycling stream and contribute to beneficial use rather than disposal. Contamination—such as food residue or mixing incompatible materials—can make recycling impractical or impossible, which is why cleanliness is a key factor. In contrast, special wastes require special handling due to hazards, residual wastes are what remains after recycling and composting, and compostable wastes are organic materials destined for compost rather than recycling into new products. So the description best fits recyclable wastes.
