Meaning of Refuse and Sewage

Refuse is  solid waste whether dry or wet which could cause land pollution e.g. nylon, paper, plastic, broken bottles, scraps, etc. Refuse wastes materials could be divided into 2 namely: biodegradable and non-biodegradable.

Biodegradable materials are materials that can decompose or decay e.g. banana peels, dead leaves, dead animals, etc.

Non-biodegradable things are materials that cannot be decomposed or decay e.g. metals, plastics, broken bottles, etc.

Sewage is a liquid waste from the environment e.g. faeces, urine, wasted water from kitchens, bathrooms, etc.
