What type of waste is derived from ordinary living processes?

Domestic sewage is the correct answer as it specifically refers to the waste generated from everyday activities associated with living, such as bathing, cooking, and toilet use. It encompasses all the waste products that come from households and residential areas, making it a direct output of ordinary living processes.

Industrial waste, on the other hand, is generated from manufacturing or industrial activities and does not originate from typical household practices. Hazardous waste refers to materials that can pose a danger to human health or the environment, often requiring special handling and disposal methods, which is not characteristic of the waste produced within normal domestic settings. Non-biodegradable waste consists of materials that do not decompose naturally, but this term refers more to the type of materials rather than the processes of living that generate them. Therefore, domestic sewage best fits the description of waste derived from ordinary living processes.
