Definition of a Solid Waste Management System


A solid waste management (SWM) system includes the generation of waste, storage, collection, transportation, processing and final disposal. This study focused on disposal options for municipal solid waste (MSW) in India. Read the Definition of Municipal Solid Waste.

Agricultural and manufactured products of no more value are discarded as wastes. Once items are discarded as waste, they need to be collected. Waste collection in most parts of the world is centralized and all kinds of waste generated by a household or institution are collected together as mixed wastes.

Solid waste management (SWM) is a basic public necessity and this service is provided by respective urban local bodies (ULBs) in India. SWM starts with the collection of solid wastes and ends with their disposal and/or beneficial use. Proper SWM requires separate collection of different wastes, called source separated waste collection. Source separated collection is common in high income regions of the world like Europe, North America and Japan where the infrastructure to transport separate waste streams exists. Most centralized municipal systems in low income countries like India collect solid wastes in a mixed form because source separate collection systems are non-existent. Source separated collection of waste is limited by infrastructure, personnel and public awareness. A significant amount of paper is collected in a source separated form, but informally. In this report, unmixed waste will be specially referred to as source separated waste, in all other cases municipal solid waste (MSW) or solid waste would refer to mixed wastes.
Indian cities are still struggling to achieve the collection of all MSW generated. Metros and other big cities in India collect between 70- 90% of MSW. Smaller cities and towns collect less than 50% (6). The benchmark for collection is 100%, which is one of the most important targets for ULBs at present. This is a reason why source separated collection is not yet in the radar.

  1. I never realized how different solid waste management systems are depending on what country you live in. I am currently researching the topic for a report I am doing for school. I didn't think the topic would be as interesting as it is. I will definitely have to include SWM systems in other countries in the report.

  3. Commercial disposal bins are used to get rid their garbage and waste management like, residential and commercial, is the only way to maintain a clean and healthy environment.
