Detailed explanation-1: -An effective approach to reduce the enormous volume of non-hazardous non-recyclable waste (namely municipal solid waste, or MSW) is incineration. The incineration can be a viable solution given that landfilling of MSW is both expensive and polluting.
Detailed explanation-2: -In 2018, approximately 146 million metric tons of MSW materials were landfilled, accounting for a 50 percent share of total waste disposal that year.
Detailed explanation-3: -Incineration could be used for disposal of several types of nanomaterial wastes: (1) consumer products in municipal solid waste, (2) wastes from nanotechnology research and development, (3) medical and infectious wastes, and (4) hazardous wastes.
Detailed explanation-4: -Source reduction, also known as waste prevention, means reducing waste at the source, and is the most environmentally preferred strategy.
