United States Manager Of Landfill Operations (MOLO) Practice Test

From waste classifications, garbage corresponds to which category?

Liquid Waste Hazardous Waste Putrescible Solid Waste Non-putrescible Solid Waste

Correct Answer:

Putrescible Solid Waste

Explanation:

Garbage is putrescible solid waste. This category covers organic materials that can decay quickly, like food scraps and kitchen waste, which readily decompose under normal environmental conditions. Because these items break down, they can cause odors, attract pests, and generate leachate, so they require more frequent collection and specific handling, such as composting or digestion. Liquid waste refers to fluids, not solids. Hazardous waste includes materials that pose health or environmental risks and need special treatment. Non-putrescible solid waste consists of dry, inert materials that don’t decompose quickly, like plastics, metals, glass, and rubble.
