Briquettes in Uganda (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.
Thanks to Mike in Kampala for a great presentation of their briquette-manufacturing unit!
A generic shape: 4 inches wide (10cm) with 1 inch (2.5 cm) hole was developed by Legacy Foundation and their world-wide entrepreneurial collaborations. These dimensions were taken as an initial point of research but soon (with the development of the Holey Roket technology) 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.
Briquettes in Malawi introduced by World Wildlife Fund for nature (WWF) were 6 inches (15cm) in diameter and 2-3 inches (5cm) in thickness, made mainly of corn husks, various leaves and dry straw-grass.
For testing purposes, briquettes in Slovenia were made of sawdust and tree leaves, also some paper. Different shapes were tested.
