Reducing open waste burning is essential for achieving clean air, clean energy access, climate change mitigation and health and well-being. Globally, over 2 billion tonnes of waste are produced annually. Household waste usually comprises a variety of materials including glass, plastics, metals, cardboard, paper, polystyrene, and organic matter such as food and garden waste. Infrequently, demolition waste, household chemicals or tyres may be included. Open waste burning may occur at major landfills, small or remote dumpsites, individual households or in streets.
