The Re-/Up-Cycling of Wood Waste in Wood-Polymer Composites (WPCs) for Common Applications

Wood-polymer composites (WPCs) are a class of materials intensively studied and promoted in the context of sustainable development, mainly when aspects related to the increasing awareness of environmental issues and waste management are considered. Feasible opportunities for producing WPCs with value-added properties intended for common applications emerge when polymers, either synthetic or from renewable resources, raw or waste, are employed in re-/up-cycling approaches. In this context, some examples of easily achievable WPCs are presented herein, namely, formulations based on different wood waste and polymer matrices (synthetic: polypropylene and malleated polypropylene as a compatibilizer; natural: plasticized starch). Their level of performance was assessed through different characterization methods (FTIR, WAXD, TGA, DSC, mechanical test, etc.). The benefits and limitations of this approach are also discussed.

Automated summary

Wood-polymer composites (WPCs) are extensively studied and promoted for their value-added properties in the context of sustainable development and waste management. Different formulations of WPCs using wood waste and polymer matrices were evaluated for their performance using various characterization methods. The benefits and limitations of this approach were also discussed.
