What term is used to define waste that is capable of being decomposed by microorganisms?

The term that defines waste capable of being decomposed by microorganisms is "putrescible solid waste." This type of waste generally includes organic materials such as food scraps, yard waste, and agricultural residues. Due to their organic nature, putrescible wastes are subject to biological processes that involve the action of microorganisms like bacteria and fungi, which break down these materials into simpler substances over time.

This ability to decompose can lead to the production of leachate and methane gas in a landfill setting, making it crucial to manage such waste properly to minimize environmental impact. In contrast, non-biodegradable waste refers to materials that do not decompose naturally, hazardous waste contains substances that can pose a significant risk to health and the environment, and recyclable materials encompass a broader category of materials that can be reprocessed and reused, not specifically linked to biodegradation.
