A review on waste wood reinforced polymer composites and their processing for construction materials

Abstract

The necessity to utilise environmentally friendly resources has emerged due to environmental management. With the demand for the production of plastics and wood materials, pollution has increased. Consequently, the attraction in natural fibre-reinforced polymer composites (NFPCs) is rapidly emerging in the construction industry, mainly to replace synthetic fibre composites. The intensified interest is associated with manufacturing ‘green’ and lightweight panels. This review provides insight into the prospects and challenges related to the processing of wood waste-reinforced polymer composites. Using natural fibres, especially waste as raw material, is desirable for developing value-added products to mitigate environmental pollution. The current materials used for the wood-based composites are reviewed as disadvantages associated with wood plastic composites, such as low interfacial bonding. Efforts such as chemical treatment are outlined to wood fibres to manufacture an environmentally friendly, cost-effective, lightweight, and biodegradable composite with enhanced structural properties was provided. Various waste plastics, plant dust, and coupling agents-based composites investigated for applications, and emerging aspects of wood plastic composite for construction materials applications are outlined.
