This document is based on brick making process in the city of Mwanza, the second largest city of Tanzania. The Mwanza Rural Housing Programme (MRHP) has trained villagers in northern Tanzania to set up enterprises making high-quality bricks from local clay, fired with agricultural residues rather than wood. These enterprises have made sufficient bricks to construct over 100,000 homes with greatly improved comfort and durability, in 70 villages. MRHP has developed processes for making high using readily– quality bricks from local clay, which are fired available agricultural residues like rice husk and cotton waste, ins tead of wood. Houses made from the fired bricks are durable, comfortable and clean. Homeowners are freed from the hassle of frequent rebuilding, and many use their improved housing for businesses as well. The quality of the bricks is such that they are now being used in building programmes in the city as well as in the rural areas.
