Abstract
This work enrolls in the context of sustainable development and protection of the immediate environment. It concerns a recycling study of wood waste, polystyrene waste and plastic waste. The objective of this study is to upgrade wood waste and plastic wastes (low and high density polyethylene) and expanded polystyrene in waste disposal in the developing countries of Africa. Two types of wood particle composites based on plastic and polystyrene polymers have been developed. The physical properties (density, water absorption and volumetric swelling) and mechanical properties (modulus of elasticity and modulus of rupture) required for their implementation are determined. The quantities found show that these composites can be used to produce self-adhesive sandwich panels or boards which will serve as a door core, false ceilings, formwork sandwich boards, interior and exterior flooring and furnishing materials.
