Production of eco-friendly charcoal with high energy efficiency “chachakan” from typha australis and coconut shells

In Africa, traditional fuels are mainly used for cooking meals. In developing countries, most mainly use firewood and charcoal. In Benin, biomass essentially represented by firewood and charcoal represents 55.1% of final energy consumption in 2020. The negative effects of the exploitation of wood energy for the production of charcoal on environment are now well known: pockets of desertification, soil erosion, climate change, etc. These effects can be measured by the increase in charcoal consumption, which depends on household size, dietary habits and also the type of stove used. This study, using the standard process for the manufacture of ecological coal, proposes ecological coals with high energy efficiency called “ChachaKan” made from two kinds of biomass which are: Typha Australis and coconut husks capable of suitably replacing charcoal wood and firewood. These analyzes revealed a sample of charcoal briquette, with a lower calorific value (LCV) of 5,289.98 Cal/g, or 72% of the LCV of the charcoal. The latter has a flammability time of 3 minutes 2 seconds.
