Manufacturer Specified Performance Parameters
Manufacturers specify performance targets including: 25% savings compared to charcoal, long lasting (1 kg burnsĀ ~ 1.5 hrs), and 92% less wood usage compared to charcoal.
Vetted Performance Status
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.
Safety
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.
Complementary Technical Systems
The Inyenyeri Fuel Pellets are part of Inyenyeri's Fuel+Stove system. The type and quantity of stoves depends on the size of the family.
