How does the use of post-consumer recycled plastics in WPC formulations affect performance?
The integration of post-consumer recycled (PCR) plastics into wood-plastic composite (WPC) formulations has gained traction as industries prioritize sustainability. However, this shift raises questions about its effects on material performance. PCR plastics can alter WPC properties such as strength, durability, and moisture resistance due to variability in recycled feedstock quality. While they reduce environmental impact, additives or processing adjustments may be needed to maintain performance standards. Studies show that optimized formulations with PCR content can achieve comparable mechanical properties to virgin plastics, though long-term weathering behavior may differ. Balancing recycled content with performance requirements remains key for sustainable WPC innovation.
