Wherever there are people, there will be problems with the generation of solid waste and residue; in other words, trash. Trash is natural or industrialized waste that when commingled produces unpleasant odor, generates bacteria harmful to the community, and loses its capacity for reuse or recycling. In modern society, many products are discarded when they break or no longer work because they have served their purpose. Most temporary-use products end up as solid waste. But much of the waste generated in households and industry can avoid becoming trash, because if it is correctly separated, it can be reused or recycled (in other words, it could fulfill other important functions). Furthermore, waste separation can be a significant source of revenue.
