What are the challenges of recycling PVC outdoor benches with mixed materials?

Recycling PVC outdoor benches with mixed materials presents several significant challenges. First, the separation of PVC from other materials like metal, wood, or fabric is complex and often requires specialized equipment, increasing costs. Second, PVC itself is difficult to recycle due to its chemical composition, which can release harmful toxins if not processed correctly. Contamination from adhesives or coatings further complicates the recycling process. Additionally, the lack of standardized recycling infrastructure for mixed-material products limits efficient disposal. Finally, economic viability remains a hurdle, as the cost of recycling often outweighs the value of the reclaimed materials. Addressing these challenges requires innovation in material separation and sustainable recycling technologies.
