Macadamia briquettes are blocks of compressed biomass material from macadamia shells. They are used for fuel in households for cooking, water heating, and space heating. In Kenya, people use firewood and charcoal for cooking. The prices of firewood and charcoal have been increasing drastically, making it less affordable for most users. Briquettes are a proven technology that provides a low-cost fuel for households that is locally made and an alternative to wood or charcoal. Fuel briquettes can also be used in institutions for large-scale cooking, and in industries for productive use.
