Solid waste refers to a variety of old and used articles, for example, stained small pieces of metals, broken glassware, plastic containers, polythene bags, ash, floppies, CDs, etc., dumped at different places. These discarded materials are also termed as refuse, garbage and rubbish, etc., and are disposed of from two sources : (i) household or domestic establishments, and (ii) industrial or commercial establishments.
The household wastes are disposed off either on public lands or on private contractors’ sites, whereas the solid wastes of industrial units are collected and disposed off through public (municipal) facilities at low-lying public grounds (landfill areas).
