Chembe, Malawi

Briquettes in Malawi were 6inches in diameter and 2-3 inches in thickness, made mainly of corn husks, various leaves and dry straw-grass.

Ljubljana, Slovenia

For testing purposes, briquettes in Slovenia were made of sawdust and tree leaves, also some paper. Different shapes were tested.

Vancouver, BC, Canada

A generic shape (4 inches wide, 1 inches hole) was developed by Legacy Foundation and their world-wide entrepreneurial collaborations. These dimensions were taken as an initial point of research but soon a bigger hole was introduced due to the side, continuous feed – to allow more airflow to the combustion process. Different holes were tested, but generally between 1.5 – 2 inches worked best.

Kampala, Uganda

Briquettes in Kampala were introduced by Legacy Foundation. A wooden lever press was made to provide a several-years manufacturing unit. Materials are prepared according to the recipe, mixed together, poured into the briquette-mold and extruded with the help of the press. They are left to dry, which generally takes 1-2 weeks, depending on the material and climatic conditions.
