Explanation:

Where does waste-to-energy fit in Solid Waste Management? Ideally, it fits in the chain after segregation (between wet waste and the rest), collection, recycling, and before getting to the landfill, although this is not always the case. The energy from waste is a crucial element of waste management because it reduces the volume of waste for disposal and also helps in converting the waste into renewable energy and organic manure. It is not necessarily the most efficient or most economical means of generating energy. “Biomethanation is a process in which biological or organic compounds are degraded to generate biogas and manure. Biogas is a mixture containing carbon dioxide and methane in varying proportions and a small quantity of hydrogen sulfide gas. Methane is a harmful gas if released in the environment as it is one of the four major gases responsible for global warming. But it is an excellent fuel”. Biomethanation is an example of a first step in the waste-to-energy generation process. Biosphere reserves are areas of terrestrial and coastal ecosystems promoting solutions to reconcile the conservation of biodiversity with its
sustainable use. Biosphere Reserve is declared to conserve some representative ecosystems as a whole for long-term. Each Biosphere Reserve is intended to contribute to the conservation of
landscapes, ecosystems, species and genetic variation; Boundaries of a national park and biosphere reserve are determined by legislation. There is no biotic interference (except the buffer zone) in national parks and biosphere reserves whereas limited interference is permitted in wildlife sanctuary.
