Waste Diversion From Landfill
Reducing and Reusing Product Packaging
Waste Disposed and Recycled (Tons)
We continually improve Trex packaging to reduce the environmental footprint of our products. In addition, we seek opportunities to recycle used packaging materials we receive at our warehouses whenever feasible. In 2024, we reached agreement with one of our corrugated cardboard suppliers to return used corrugate for re-use in its 100% recycled packaging material. We recycled over 470,000 pounds of corrugate through this practice in 2024. In addition, we partnered with a merchandising vendor to retrieve dunnage (thin wooden strips that separate bundles of deck boards while in transport) from the vendor’s decking shipments. By returning the dunnage to Trex for re-use instead of sending it to landfill, this vendor is helping to divert nearly 36,000 pounds of material from landfill annually. In 2024, we also changed the packaging design for one of our railing kit SKUs to reduce the amount of cardboard required by more than 50%, with no adverse effect on shipping durability. This initiative will save approximately 7,400 pounds of cardboard annually.

As part of our landfill diversion strategy, nearly all the scrap composite materials from our manufacturing are recovered and re-incorporated into our processes—a circular ‘closed-loop’ system. In 2024, we commissioned a third-party audit of our waste streams to better understand both the volume and the types of waste that Trex generates. We are using the results of this audit, which concluded in early 2025, to help identify and prioritize additional waste reduction opportunities at Trex locations. LOGO USAGE We disposed of approximately 17,112 tons of non-hazardous waste in 2024, a 6.7% increase compared to 2023. Our recycling of non-hazardous waste increased by 95% in 2024, to 7,528 tons. The increase is due to higher overall volumes and improved tracking of recycled streams. We have not made any significant changes to our waste handling procedures that would have diverted waste from landfill. Purge, a byproduct of waste PE reprocessing, accounts for a significant proportion of our non-hazardous waste each year. During 2024, we partnered with a materials management company to divert 63% of our purge waste from landfill for conversion into energy. This process generated nearly 1,100 MWh of electricity, contributing to the energy grid supplying Trex operations in Virginia. We dispose of all hazardous waste safely and in compliance with regulations. We sort and send universal waste, a subset of hazardous waste, to off-site recycling facilities. In 2024, we recycled all but about 200 pounds of hazardous waste.
