Implementation of the Madras Waste Exchange

The Greater Chennai Corporation is having Resource recovery centers(RRC) and Micro compost centers(MCC) in all 15 Zones across Chennai. The RRC’s do segregation of waste collected from the households and markets of respective zones. There are around ten to fifteen categories of segregation types depending upon waste produced in zones. The MCC’s are used to produce compost from wet waste.

The segregated waste in RRC’s are of less value and selling them to market is becoming challenge for corporation. Further the availability of RRC’s and MCC’s are not known to many.

The Madras Waste Exchange( Online Platform)  will act as a platform to bridge the corporation’s segregated waste to the potential buyers.

The Waste Exchange will act as connection between the following people.

  1. Greater Chennai Corporation with Buyers of waste, Entrepreneurs.
  2. Non-government entities like school, college, office and bulk waste generators with buyers.
  3. Greater Chennai Corporation with non-government entities.

Current Scenario

Project Approach

Project methodology


Finding the key drivers, challenges and opportunities for the global solid waste management market and how that can be used for waste produced in India. Understanding how local solutions (Wards, Villages) and Private innovative solutions (Startup’s, NGO’s) in SWM can be scaled up to meet the waste management requirements across India. Creating Framework to find Ways by which ULB’s can attract Public and Private Investments in waste management.

Madras Waste Exchange will use Quintuple approach to bring in various stakeholders from Experts to NGO’s, to devise a framework for creating a Waste Exchange which will act as one stop solution for waste trade and waste management issues. And to create a market for processed waste and waste products by exploring secondary markets and agriculture markets.


The waste exchange application is designed in a multitenant model. It can be scaled up to any number of cities. Complete country can use this application and benefit out of it. The buyer from north of India can buy or sell in South of India once scaled up.

The scalability can be done both horizontally and vertically. Horizontally by expanding to any number of cities. Vertically by including any kind of waste allowed by law of country.

Since the application comes as web portal and mobile Android application, it can be accessed from any part of the world .

Financial Sustainability

The application is designed in a self sustaining way. These are the following ways which makes this platform attractive and self sustaining.

  1. Since it’s a trading platform, the seller of the segregated waste can sell at a cost fixed by him.  Here the seller is Corporation, so the corporation will get profit out of this platform which inturn could be used for the maintenance cost of the waste exchange application.
  2. The Citizens can also use this application in the same way like Corporation. Minimal charge can be applied on transactions made by non-government entity. This cost will help in sustaining the waste exchange as well as making it a profitable application.
  3. The opportunity cost created by the application is very huge. Since it induces segregation at source and incentives people to sell their waste instead of dumping it, the collection cost in terms of fund, man power, vehicle and landfill space will reduce drastically. This way corporation can save huge amount of resource utilisation.


The proposed Waste Exchange is first of its kind in India.

The Waste Exchange once up and running will be helpful in the following ways,

  1. Corporation officials can monitor the real time data and availability of materials in RRC’s and MCC’s across all 15 Zones in Chennai.
  2. Zone wise performance can be analyzed.
  3. Report of segregated waste in required format can be taken anytime.
  4. Buyers can directly buy our segregated waste through the Exchange.
  5. Any citizen can act as seller. Schools, colleges, apartments and bulk waste generators can register in this platform and sell their waste. This will reduce the amount of waste ending in Landfill.
  6. Anyone can register as a buyer.
  7. Corporation can monitor the amount of waste sold by non-government entities across Chennai.
  8. E-waste, C&D waste will also be handled by this platform.
