2.3. Municipal Waste (Solid Waste and Sewage)

Solid waste (trash or garbage) is generally produced by individuals and include unneeded or broken personal items, spoiled food, paper, garden plants, plastics, metals, textiles, etc. Municipal solid waste may contain substances potentially harmful to human health and the environment.

Sewage is a highly complex mixture of wastes, usually dominated by fecal materials (organic matter) but also containing toxic chemicals (ions of metals, pesticides, other toxic chemicals, etc.) that have been dumped into the disposal system by industries and home owners.
