The enterprise installs and markets three types of biogas digesters to urban and rural households, schools, prisons, hospitals and tourist lodges in Uganda. Households can obtain the digesters with a pay-as-you-go financial plan or renting the appliances in monthlyinstalments. After-sales services are offered for the first six months after installation. 

The three designs – fixed dome, floating drum and flexible balloon – decay organic material collected from agricultural waste or enterprise-designed latrines to produce biogas fuel for cooking and heating.

Biogas digesters installed by Green Heat improve household health and life expectancy by decreasing air pollution from traditional energy sources and improving waste management. Income and productivity also increase in households as workload spent on gathering firewood decreases by two to three hours each day.
