Through a partnership with UNHCR, Inyenyeri provided 300 refugee families in Kigeme camp with their Stove+Fuel solution. These families stated that cooking with the stove had a positive impact on their health by reducing their exposure to toxic emissions. The UNHCR also stated that the biomass required to cook meals reduced by 80-90% compared to the baseline.
Fuel pellets are usually a safe fuel for small users like households. However, since they are made with combustible materials, the risk of fire will always be a concern as well as harmful gases emissions like carbon dioxide and monoxide, nitrogen oxides, and hydrocarbons.
