The main causes for the rapid growth in the quantity of solid waste are:

1. Overpopulation
2. Urbanization
3. Affluence
4. Technology

Waste pollution is when waste (mainly human generated waste) harms or effects humans, animals, the natural environment (by soil contamination, air pollution, water pollution), or even disrupts aesthetics.

Most common Municipal Solid Waste generated:
Paper and paperboard
Food
Yard Trimmings
