In the African context, where agricultural by-products and natural resources are often underutilized or considered waste or invasive species, this study aims to valorize locally available raw materials through the development of fully bio-based insulating composite materials. The materials were produced using typha, rice husk, residues from threshing millet ears, and cassava starch, through a simple and reproducible process accessible even at an artisanal scale. A total of 25 formulations were created by combining one to three of these raw materials with a natural binder. The resulting composites were characterized. The bulk density of the materials ranged from 198.64 to 361.02 kg/m3, while their thermal conductivity varied between 0.07 and 0.17 W/m·K. These results highlight the strong potential of these bio-based composites for use as thermal insulation in sustainable building applications.
Author Keywords: materials, bio-sourced, insulation, sustainable development, valorization.

Abstract: (french)
Dans un contexte africain où les ressources naturelles issues de l’agriculture sont souvent sous-exploitées, ce travail s’inscrit dans une démarche de valorisation de matières premières locales fréquemment considérées comme des déchets ou des envahissants. L’étude porte sur l’élaboration et la caractérisation thermo physique de nouveaux matériaux composites isolants, entièrement biosourcés. Ces matériaux ont été fabriqués à partir de typha, balle de riz, résidus issus du battage d’épis de mil et amidon de manioc, à l’aide d’un procédé simple et reproductible, accessible même à l’échelle artisanale. Vingt-cinq formulations ont été réalisées en combinant une à trois de ces matières premières avec un liant. Les matériaux obtenus ont été caractérisés. Les résultats montrent une masse volumique variant entre 198,64 et 361,02 kg/m3, et une conductivité thermique comprise entre 0,07 et 0,17 W/m·K. Ces performances indiquent un bon potentiel d’application dans l’isolation thermique des bâtiments durables.
