Making of the Palm kernel briquettes: The charcoal was pulverised using a manually operated blender. The charcoal fines were screened through a 250 micron sieve. Cassava starch was used as a binder. The starch was prepared from raw cassava root which was peeled, washed and sun-dried. It was then pulverised. 50g of the cassava flour was dissolved in 100ml cold water. 400ml water was put to boil in a container.
