Environment Programme According to the Basel Convention:

• Municipal Waste includes Household waste, Commercial waste, and Demolition waste
• Hazardous Waste includes Industrial waste
• Bio-medical Waste includes Clinical waste
• Special Hazardous waste includes Radioactive waste, explosives waste, and Electronic waste (e-waste)

On a global scale it is difficult to report waste because countries have different definitions of waste and what falls into waste categories, as well as different ways of reporting. Based on incomplete reports from its parties, the Basel Convention estimated 338 million tonnes of waste was generated in 2001. For the same year, OECD...
