The flexibility of Waste Concern’s composting model is such that it can be adapted to any situation both in urban and rural areas. Moreover, it can be implemented in slum areas. It can be implemented on a small scale, medium scale, or large scale. The small scale model allows for 3 tons of organic waste to be processed daily, while the medium scale model permits processing 3 to 10 tons of organic waste per day. More than 11 tons of organic waste can be processed daily using the large scale model.
Besides reducing green house gas emissions, each of these models also generate valuable carbon credits on the international market.

Waste Concern’s initiatives combine the public and community spheres with private sector involvement. This image offers an example: seed money from a donor (in this case, the UNDP) is utilized by Waste Concern - in partnership with the Ministry of Environment and Forests, Dhaka City Corporation, and Public Works Department. The money and knowledge are utilized towards implementing community-based, solid waste management projects. The end result is that communities participate in door-to-door waste collection, producing organic compost that is sold to rural farmers at lower prices via fertilizer companies.

 


This image shows a different model employed by Waste Concern for processing organic waste. The Kyoto Protocol’s Clean Development Mechanism and the carbon trading market can play a role in forming partnerships between the public, private, and community spheres. In this example, the Clean Development Mechanism’s Board approves a compost plant project owned as a joint venture by Waste Concern and World Wide Recycling; approval from Dhaka City Corporation is also extended. The compost plant obtains organic waste from the urban population through direct collection from vegetable markets. The resulting higher-yield, lower-cost compost is sold to rural farmers, and the carbon credits obtained are sold on the international market. The critical aspect of this model is that city authorities bear no costs whatsoever in the implementation of this project. Waste Concern undertakes the waste collection free of cost; the land for the compost plant also belongs to Waste Concern. This model saves the city numerous costs associated with waste collection, transportation, and disposal.
