Numerous studies and investigations have been done on the origins and properties of wastes, as well as the potential negative effects of improper treatment and best global practises. The definition of a waste, however, is still a matter of debate. How much do we actually know about what constitutes waste? What have waste management practises looked like historically? In order to provide answers from earlier studies, the current research paper aims to examine these crucial questions. To address the research aims, the report took a descriptive method. In particular, the work uses a descriptive approach to gather data from books, journal papers, and reports from environmental groups that have undergone peer review. Waste was determined to be a significant problem extent ambiguous, since a substance can only be considered garbage when the owner designates it as such. This is especially true given that one person might perceive a chemical as waste while another might see it as a resource. However, it was maintained that in order to properly regulate, it is necessary to define exactly what wastes are. Waste segregation is another crucial step in this research paper because it enables efficient Reuse, Recycling, and Recovery (RRR). Unfortunately, it has not received much attention and is often used informally in poor nations. It is also impacted by a lack of understanding, lax enforcement of regulations, a lack of financial incentive, and low planning priority. This study was carried out on metropolitan cities in India. The research will continue on issues like the reuse and recycling of plastics, electronics, and the selling chain for metals is informal, going from households to waste collectors to recycling facilities, and then to industries. Waste segregation in various industries and how would it advance the growth of the nation.
