摘要

With the growing environmental concerns and the pursuit of sustainable solutions, the utilization of agricultural residues has been gaining prominence, particularly in the materials sector. Coffee husk is an abundant waste of coffee production and represents a lignocellulosic resource with significant potential for application in various industrial sectors. This study evaluated the physicochemical, thermal, and morphological properties of coffee husk particles (CHP) to assess their feasibility as a filler in polymeric biocomposites. The collected CHP were cleaned, dried, and ground for analysis. The particles exhibited density and chemical composition comparable to other lignocellulosic materials already used in biocomposites. Thermogravimetric analysis indicated thermal stability of CHP up to 200 ℃. X-ray diffraction revealed a crystallinity index of 33.62%, and the morphological analysis showed that the material has a rough and irregular surface, which may enhance mechanical adhesion to the polymer matrix. The CHPs have promising potential as a sustainable material for biocomposite production, contributing to the utilization of agricultural residues and reducing environmental impacts.
