  ABSTRACT: The technique of briquetting biomass to produce green charcoal offers considerable potential to meet the need of the high energy demand and help protect the environment in rural areas. This study aims to formulate a green charcoal with a high calorific value and low ash content. The green charcoal was prepared from coconut shells, peanut shells, sawdust, potato peelings, and cow dung and used as a binder. These residues were mixed in the proportions suggested by the Box-Behnken plan in order to model and optimise the manufacturing process. The physico-chemical analyses revealed that the best results were obtained with briquettes prepared from 50% cow dung, 10.17% coconut husk, 19.83% potato peelings, 12.42% peanut husk and 7.58% sawdust. These have a calorific value of 3031 kcal/kg and an ash content of 47.49%. Mechanical and combustion tests confirmed the quality of the green coal produced despite the white smoke and high ash content.
