3. Boost Internal Circularity: We recycle nearly all production scraps back into our products. This includes line startups, scraps, cutoffs, rejects, field returns and even used Trex boards. In 2025, we conducted a waste audit to identify more opportunities for in-house and external recycling. 4. Recycle End-of-Life Products: We are exploring ways
While our demand for raw materials can vary, rapidly scaling sourcing up or down is not always practical. The organizations we partner with to collect waste PE film and reclaimed wood rely on Trex for consistent, dependable material flows. To support these partners and build resilience into our supply chain, we have historically invested in warehouse capacity and inventory buffers. As market conditions and growth projections for waste PE and reclaimed wood have evolved, we have adjusted this approach—strategically right-sizing warehouse capacity and inventory levels while maintaining strong partner relationships and operational flexibility. At the same time, we continue to innovate to optimize our use of recycled and reclaimed materials. By diversifying sourcing channels
and improving manufacturing efficiency, we ensure that Trex remains agile, responsible and positioned to lead in circular practices, even as conditions change. We follow a four-pillar strategy to maximize the circularity of our decking products and ensure that 95% of our composite decking materials come from recycled and reclaimed sources: 1. Expand Relationships: We actively seek new sources of waste PE film and reclaimed wood. 2. Invest in R&D: We invest in research and development to test and recover additional streams of waste PE film that others have not yet tapped into for recycling.
Trex sources approximately 967 million pounds of waste PE film and reclaimed wood annually to manufacture our decking products. 1 The quantity of material we source for recycling varies according to production needs, inventory in storage and market conditions for waste PE and wood.
to channel used Trex products back into production. While our processes are ready to accept this material, the main challenge is the logistics of recovering end-of-life waste.
