Answers
Waste is defined as discarded material which has no value in normal use or for ordinary use. Solid wastes are those undesirable, useless and unwanted materials and substances that come from human and animal activities. Generation of wastes is inevitable. The management of wastes assumes importance in view of the environmental hazards they pose. According to UNICEF, the solid waste can be classified into biodegradable and non biodegradable waste. Biodegradable waste, that are completely decomposed by biological processes either in presence or in absence of air are called biodegradable. e.g. Kitchen waste, animal dung, agricultural waste etc. Non-biodegradable waste, which cannot be decomposed by biological processes is called non-biodegradable waste. These are of two types-Recyclable: waste having economic values but destined for disposal can be recovered and reused along with their energy value. e g. Plastic, paper, old cloth etc. Non-recyclable: waste which do not have economic value of recovery. e.g. Carbon paper, thermo coal, tetra packs etc. Disposal of non-biodegradable waste is a major concern, not just plastic, a variety of waste being accumulated. There are a few ways to help non-biodegradable waste management. In the present study we have discus about the impact of non biodegradable waste on the environment and also focus on its safe disposal for sustainable environment.
