What are the biodegradability claims and controversies surrounding WPC outdoor planters?

WPC (Wood-Plastic Composite) outdoor planters are often marketed as eco-friendly alternatives to traditional plastic or wooden planters, with claims of biodegradability and sustainability. Manufacturers highlight that WPC materials combine recycled wood fibers and plastics, reducing waste and offering durability. However, controversies arise over the actual biodegradability of WPC, as the plastic components may not break down easily in natural environments. Critics argue that WPC planters can still contribute to microplastic pollution, despite their "green" branding. Additionally, the recycling process for WPC is complex, raising questions about its long-term environmental impact. While WPC planters are a step toward sustainable gardening, their true ecological footprint remains debated among experts. Consumers are advised to research and weigh the pros and cons before choosing WPC for their outdoor spaces.
