Definition of Solid and Semi-Solid Waste affecting Environment

Waste generally means something  unwanted but its precise definition differs from one country to another. The Chinese often say that a thing can be both a raw material and a waste at the same time. A material is considered as waste until it is considered as beneficial again. Thus a solid (or semi-solid)  material is generally considered as solid waste in the eyes of the producers when it loses its worth to them and is discarded.
