Currently there is no organic waste management strategy in Tanzania. In rural parts, waste is simply thrown away or burned in a pit. In vegetable markets in towns, produce unfit for sale are simply dumped on site and left to rot. This poses a health hazard for people, attracts rats and creates undesirable odor. The lack of any management not only creates tons of waste everyday, but it also deprives Tanzanian soils of rich nutrients which can help farmers to increase their yields.
My idea is to bring collection containers to the market places. Market sellers will be encouraged to dispose of their waste inside the containers. Once the container is filled, it will be transported to a site, where it will be processed into compost.
We plan to execute this program along the Iringa-Mbeya highway starting with the town of Mafinga where we currently reside. After success in the Southern Highlands, this could be replicated easily across the country.
We have a 200 acre farm in Iringa which can partially be converted into the composting site. The waste will be mixed with other organic materials such as straw and soil. The mixture will be turned around and watered manually to kick in the decomposing process. Once well aged, this 'black gold' will be packaged into 50kg bags and sold back to the farmers in the region.
