Eco-Friendly Decking

Always Green

We make Trex® eco-friendly composite decks from an innovative blend of 95% recycled wood and plastic film—that’s almost the whole thing. On top of that, our company uses some of the most earth-friendly manufacturing processes in the country, reclaiming factory waste and eliminating the use of harmful chemicals. The fact is, being green is in our DNA. We've been this way for more than 20 years, well before green was a buzzword. Because in the end, all of us want to look out on our decks and know that we’ve done our part.

Why a Trex® Composite Deck is a Green Deck

Trex recycles reclaimed wood to make high performance composite decking

Recycled Wood

Locally sourced reclaimed wood that would otherwise end up in a landfill finds its way into Trex high-performance composite decks. By using reclaimed sawdust, we never have to cut down a tree to make our products. Ever.

Trex is one of the largest plastic bags recyclers in the U.S. and manufactures recycled plastic decking.

Recycled Plastic Film

The recycled wood in our decks is combined with recycled plastic film from a variety of sources ranging from the overwrap on paper towels to dry cleaner bags, sandwich bags, newspaper sleeves, and grocery and shopping bags. Here’s an interesting fact: the average 500-square foot composite Trex deck contains 140,000 recycled plastic bags! That makes us one of the largest plastic bag recyclers in the U.S.

Trex composite decking is made of 95% recycled plastic and wood materials.

Eco-Friendly Manufacturing

Trex’s proprietary, eco-friendly processing method eliminates the use of smoke stacks while our bi-coastal factories reduce fuel consumption and CO2 emissions.  Additionally, almost 100% of our factory runoff and refuse are recycled back into the manufacturing line. Our trailers even run on vegetable-based oil hydraulics.

The Big Picture

Trex works along with other U.S. Green Building Council members to transform the way building and communities are designed, built and operated with the goal of creating environmentally and socially responsible spaces that improve the quality of life.

Production Process

Trex recycles plastic and reclaimed wood to make high performance composite decking

Sawdust and plastic film are purchased

To manufacture recycled plastic decking, Trex's production process cleans plastic film and grinds it into granules.

Plastic film is cleaned and ground into granules

Plastic film and sawdust are combined and heated

Mixture is mixed to a soft, pliable consistency

To create composite decking, Trex forms an eco-friendly recycled plastic and wood mixture into boards using profile dies.

Towards the end of Trex's green production processes, the plastic wood boards are cooled and cut to length.

Trex high performance composite decking is inspected by quality control professionals to ensure your recycled plastic and wood deck boards meet all expectations.

Boards are inspected by Quality Control for defects, strength and color accuracy

Finished Trex deck boards are wrapped and shipped to complete the eco-friendly production cycle.

Recycling is a Beautiful Thing

As one of the largest plastic film recyclers in the U.S., Trex saves 400 million pounds of plastic film and wood from landfills each year. So in addition to contributing to a healthier environment, our eco-friendly recycled decking also contributes to your LEED points—not to mention your good karma. Learn about Trex and the LEED Green Building Rating System.

Created in part by the U.S. Green Building Council, LEED is a point-based system designed to honor building projects that incorporate efficient, cost-effective and safe eco-friendly products. Trex products can add up to five points to your project—four points in the Materials and Resources category for being composed of up to 95% recycled materials, and one point in the Innovation and Design category.
