Waste

Waste is generated at all stages of human activities : during the extraction of raw materials, the processing of raw materials into intermediate and final products, the consumption of final products, etc. Municipal waste is only about 10% of total waste, but its management and treatment often represents more than one-third of public sector financial efforts to abate and contral pollution. Inappropriate waste management impacts human health and the environment through soil and water contamination, air quality, climate, land use and landscape.
