development of alternatives energies illustrates the common interest of all
countries in reducing greenhouse gas emissions and combating climate change.
Thermochemical treatment of municipal solid waste, agricultural and forestry
wastes is a major challenge for this XXIst century to replace
petroleum fuels. Thermogravimetric analysis (TGA) makes it possible to
elucidate the thermal behavior of Casamance (Senegal) biomass residues, mass
losses and decomposition rate, under inert (N2) atmosphere and oxidizing
(O2) atmosphere. Carbonization and briquetting techniques of these various residues encountered in this part of Senegal country,
by densification in order to produce fuel briquettes (call biochars) will be
used to improve stoves for cooking. Samples used in this study are peanuts
shells (PNS), cashew nut shells (CNS), palm nut shells (PLS) and millet stems
(MS). Elemental and approximate analyses make it possible to determine the CHNSO* composition, volatile matter,
fixed carbon and ashes content of the samples used. Higher heating values (HHV)
of the former residues are ranging from 28.60 MJ·kg-1, 26.51 MJ·kg-1, 29.69 MJ·kg-1 and 24.93 MJ·kg-
