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.

That would give us an initiative on how to proceed with your activity!
