Which of the following is a type of garbage listed among the nine types?

• A. Recyclable garbage
• B. Rags
• C. Paper products
• D. Cooking Oil

Answer: (D)

Handling garbage often involves recognizing different waste streams by their properties and how they should be disposed of. Cooking oil is listed as a type of garbage because it is oily liquid waste that doesn’t belong in regular trash or down the drain. Its lipid content can clog pipes, disrupt sewage treatment, and pollute waterways, so it requires separate collection or recycling rather than being mixed with other waste. That special handling is why oil is singled out as its own waste type in the nine-type scheme. Recyclable garbage and paper products are materials meant for recycling, not an oily-waste category, and rags fall into textile or general waste depending on contamination, so they aren’t the oily waste type highlighted here.
