Centralized Method: This method involves collection of municipal waste from all over the local area and by means of land-filling, dump outside the city limits. This process looks at door-to-door collection of solid waste by waste pickers who hand over to the collection team who then discard the collected waste in the landfill. The waste pickers are employees of the Municipal Corporation or Nagar Panchayat. The collection team is generally contracted out by a tendering process.
De-centralized Method: The waste is collected ward-wise and is segregated at source into bio-degradable and non-biodegradable (Karnataka-model). The biodegradable waste is composted at a nearby facility by different methods of aerobic and anaerobic composting. The non-biodegradable waste is further categorized into paper, plastic, metal and other waste and then further collected by recyclers for up-cycling or down cycling of products.
