Recycled plastic lumber has become an increasingly popular material for urban outdoor furniture due to its sustainability claims and initial durability. But how does it actually perform over years of exposure to the elements and constant public use? This material, typically made from post-consumer plastics like bottles and containers, is engineered to resist many of the issues that plague traditional wood. Unlike wood, it does not splinter, rot, or require painting or staining to maintain its integrity. It is also highly resistant to moisture, insects, and graffiti, which is a significant advantage in an urban setting.
Over time, the primary considerations become UV stability and structural integrity. High-quality recycled plastic lumber is treated with UV inhibitors during the manufacturing process to prevent fading and brittleness caused by prolonged sun exposure. While some gradual color fading can occur over many years, the material does not degrade in the same way that untreated wood might. In terms of strength, it maintains its load-bearing capacity well, though it can have a slight tendency to warp under extreme, consistent heat if not properly installed with adequate expansion joints.
From a maintenance perspective, it holds up exceptionally well. A simple cleaning with soap and water is typically all that is needed to restore its appearance, making it a low-maintenance and cost-effective solution for city parks, plazas, and public spaces. The long-term performance of recycled plastic lumber solidifies its role as a durable and sustainable choice for urban furniture, capable of withstanding heavy use and harsh weather conditions for decades.
