Having been conceived, tested and refined in Dhaka, the IRRC approach was found to be robustly suited to the realities of low and middle-income cities. Under this project, ESCAP and Waste Concern, in partnership with national and local governments, community groups and technical teams, promoted the IRRC model in 17 cities, ultimately establishing facilities and pursuing associated activities in seven of them (Figure 4). The centre is a small-scale facility that can receive different types of waste, including organic and inorganic waste, and then transform it all into resources, such as compost, biogas and other fuels and clean recyclable material.
