Trex® Responsible Manufacturing

We transform waste materials into durable and attractive decking through efficient manufacturing processes that minimize energy, waste and water use. When we invest in new facilities, we seize the opportunity to build in our sustainability principles — for example at our new facility in Little Rock, AR.

How We Operate

A person wearing a bright green shirt and holding a clipboard stands in front of several large transport trucks. The setting appears to be an outdoor loading or shipping area, with sunlight illuminating the scene. The shirt displays the text 'Trex,' and visible numbers on the trucks include 49, 126, and 69. The individual is wearing a cap and safety glasses, suggesting a work environment.

Energy and Emissions

We design Trex facilities to run efficiently with a focus on installing the best available energy-saving equipment. We extend this focus to transport, selecting efficient trucking logistics, reducing truck idling time and using rail where possible.

A person in a green shirt is seen working at a recycling plant, sorting through shredded materials on a conveyor belt. The industrial setting features large machinery and overhead lighting, with piles of processed waste visible. The environment is utilitarian, with muted colors and a focus on the recycling process. No visible text or numbers are present in the image.

Waste and Recycling

We minimize waste at the source and recycle nearly all our scrap and plastic packaging back into the manufacturing process for our composite decking.

Two green-cushioned lounge chairs are arranged on a wooden dock overlooking a calm lake at sunset. Decorative lanterns, a small table, and a potted plant enhance the relaxing outdoor setting. The sun sets behind trees, casting a warm golden glow across the water and dock.

Water Use

Water is a precious resource to be conserved and protected from pollution. We use closed-loop recirculation systems at our facilities, recycling 99% of the process water we use.

A peaceful dock extends over a marshy waterway, with two kayaks and a canoe resting at the edge. The scene is framed by a large, moss-draped tree and features two empty chairs at the dock's end, facing the water. An American flag is visible in the distance, and the setting is bathed in soft, natural light with a serene blue and green palette.

Biodiversity

We assess biodiversity impact when constructing new facilities, including our newest plant in Little Rock, and when making significant changes at our existing sites. We continued to support the established biodiversity at our existing sites through efforts such as planting wildflowers, protecting waterways and maintaining wildlife habitat.
