The term "biomass" refers to organic matter that has stored energy through the process of photosynthesis.
In this case, the biomass is supplied through the processing of key crops (such as maize, rice or groundnuts), which produces waste, known as feedstock, to power the gasifier. Heated in a low oxygen environment, biomass produces gasses which can be used to power an engine, thereby producing electricity. Once this waste has been utilised to produce electricity, it can also be sold as a charcoal replacement product, known as biochar.
The social impact of the project comes from supporting farmers to access affordable, high quality value addition services for their products such as biomass-powered milling. This ensures sustainable incomes and supports a move away from subsistence farming towards small-scale, commercial production. Moreover, profits can be reinvested into project activities, to scale up the model throughout Uganda, and eventually overseas.
