Green coal or bio-coal is coal produced with rich biodegradable
materials, elaborated from agricultural and household residues with a high
percentage of carbon. This green charcoal (fuel briquettes) is an alternative to charcoal. Well known for its contribution to greenhouse gas emissions, charcoal
is one of the causes of tree felling. The valorization of waste by the
manufacture of biofuels could be an alternative to the use
of charcoal. The general objective of the present study is the valorization of
nine biomasses from Togo as raw materials. Specifically, physico-chemical
characteristics such as dehydration, acidity, and conductivity were determined.
Information on the structure and composition of the biomass was found. These
data on the nature of the biomass were found through the use of Fourier Transform
Infrared (FTIR) and Thermogravimetry (TGA). The promising results inform on the
nature of the analyzed samples and allow the selection of the best biomass
which would give an important thermal conductivity for the manufacture of the briquettes, but also
of the binders to be used according to the physico-chemical characteristics
like the pH.
