We make Trex® eco-friendly composite decking boards from an innovative blend of 95% reclaimed timber and plastic—that’s almost the whole thing. And 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.

Trex composite decking boards don’t compromise on performance or reliability. They’re hassle-free and don’t require sanding, staining, or painting, which means less time working on your deck and more time relaxing outside. Your deck will look like new for years to come thanks to the protective outer shell on each Trex board, which can outlast harsh temperatures and inclement weather.


As one of the largest plastic recyclers in the U.S., Trex saves 800 million pounds of reclaimed timber fibre and recycled plastic film diverted from landfills and reclaimed wood fiber used annually, so our eco-friendly decks contribute to a healthier environment.

Trex recycles reclaimed wood to make high performance composite decking


Reclaimed timber that would otherwise end up in a landfill can be used to make a Trex high-performance composite decks. By using reclaimed sawdust, we never have to cut down a tree to make our products. Ever.

Unlike timber, composite decking can withstand common deck issues like rot and termite damage.

What is the difference between recycled and reclaimed timber?

While the two terms are sometimes used interchangeably, it’s important to understand the difference between recycled and reclaimed timber. Recycled timber refers to materials that are salvaged from another existing structure. Recycled timber could be sourced from a bridge, deck, or building among other places. Reclaimed timber is not sourced from other structures and instead comes straight from the forest floor.

It can be beneficial to use both recycled and reclaimed timber. Not only does this help to reduce waste, recycled and reclaimed timber are often more cost effective than other materials. Despite the price difference, both recycled and reclaimed timber can be durable and long lasting.

Trex is one of the largest plastic bags recyclers in the U.S.


The reclaimed timber in our decks is combined with recycled plastic 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 was built on green principles


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.

It’s important to know what your deck is made of and how the materials affect the environment. Most people are unaware that plastic or PVC decking is actually made from virgin plastic vs. recycled plastic, which is mostly created using coal, natural gas, or petroleum. Composite decking is more eco-friendly than plastic decking, and composite boards look more like real timber decks.

Composite decking is also more weather resistant than plastic and timber, and will resist swelling and contracting in extreme weather. If you’re looking for environmentally-friendly decking materials and don't want to sacrifice quality or aesthetics, composite decking is the best option for you.

We haven't felled one tree in the making of Trex high-performance composite decking. Ever.

Our commitment to salvaging and reusing materials begins at the local level, with the sponsorship of several community-based recycling programmes at major national grocery and retail chains.

Trex is excited to sponsor each year the Plastic Film Recycling Challenge in schools and communities all across the United States. The challenge brings to life for children the importance of recycling and keeping plastic film out of the nation's landfills. Schools compete against each other to collect the most plastic film, such as grocery bags and case overwrap, which will eventually be recycled and made into beautiful Trex recycled plastic timber decking and railing products. Youth get excited and interested in recycling early and Trex is happy to make possible a programme that encourages recycling and community involvement.



Widely recognised as the leading eco-friendly decking and railing product of choice, Trex has always been at the forefront of the green building industry. As a proud member of the U.S. Green Building Council, we’re continually working to improve the way America’s buildings and communities are designed, constructed and operated.

Trex has received numerous environmental awards, including:

  • The Governor of Virginia's Environmental Award for "impressive tonnage of recycled grocery bags and pallet wrap kept out landfills"
  • Connecticut College's Inherit the Earth Gold Medal for "demonstrating that business can be profitable, while meeting the needs of environmental sustainability"
  • The Governor of Virginia's Environmental Excellence First-Place Award for "Outstanding Environmental Projects" (twice received)
  • Winslow Management Company's Green Award for companies that positively contribute to both the environment and their shareholders
  • The "Excellence in Plastics Recycling" award from the Society of Plastic Engineers Recycling Division
  • The E-3 Green Company Executive Award from Pennsylvania-based Emerald Asset Management for CEO Ron Kaplan’s leadership and commitment to excellence
