Safe and effective disposal of municipal solid waste (MSW) is a challenge of the era. Uncontrolled growth of MSW has become a major concern for Urban Local Bodies (ULBs) throughout the world. Today across most of the municipal corporations; waste segregation has become a menace due to ill-practice of manual segregation. Manual segregation of waste is highly infectious and commercially non-viable method. MSW sites have foul odour that may poise health risk to the site workers working in surrounding localities. Composition of MSW in general varies from pocket to pocket and presences of undesirable components are the most challenging aspect. There are many managerial solutions to the problem which relates to the segregation of wastes at source by human intervention. Optimization of waste collection vehicles along with waste collection bins are established techniques, success of which speculates because people should have to follow the rules for proper waste disposal. In its consequence, people should be awaked about the safe and proper disposal of generated MSW. Hence dependence on the users, instructors, and unawareness certainly will develop threats which frequently lead to improper segregation and disposal of waste which ultimately causes uncontrolled growth of generated municipal wastes at every nook and corner. Mechanized segregation system is need of the hour to handle this huge quantity of waste generated day by day. In addition to that proper segregation system shall help in effective conversion of waste into wealth. The developed mechanized segregation system is capable of segregating metallic material (metal body, metal container etc.), biodegradable material (foods, vegetables, fruits, grass etc.), non-biodegradable (plastics, packaging material, pouches, bottles etc.) as well as inert material (glass, stones etc.) from municipal solid wastes.
