Our number one goal is to create the most durable alternative lumber known to man. But saving the planet? Well, that’s a close second.

Building a Stronger Planet

As an early pioneer in the plastic lumber industry, we’ve been committed to developing sustainable solutions for over two decades. Made primarily from recycled milk jugs and laundry detergent bottles, our products meet criteria for the USGBC LEED requirements. In addition, we also use an environmentally-friendly process that produces minimal greenhouse gases. As you use our materials to build stronger projects, know that you’re also helping to build a stronger planet.

  • Reduce Air & Water Pollutants

    Unlike wood, our structural plastic lumber doesn’t need to be chemically treated so there’s no leaching of chemicals into the ground or water.

  • Reduce Toxic Exposures

    Recycled HDPE composite plastic lumber doesn’t emit toxins and irritants into the air or water like PVC or treated wood does.

  • Reduce Waste & Landfill Pile-Up

    We give consumer plastics new life and constantly reuse scrap material to manufacture more product, reducing waste dramatically.

  • Reduce Deforestation

    Unlike traditional wood, alternative lumber eliminates the need for deforestation – saving countless trees that wildlife depend on for food and shelter.

Mother Earth will thank you.

Green building is a holistic concept that promotes positive effects on the environment throughout the entire building life cycle, from building design to construction and even the manufacturing process of the building materials. The aim of green building is to make efficient uses of land, materials, energy, and water, generate minimal waste, and provide healthy environments by restoring, improving, or enhancing the natural environment. Tangent’s green construction materials are designed with these principles in mind. With the climate crisis looming, more companies are adopting green practices and green construction products into their overall business strategy every day.

Each year, Tangent diverts millions of pounds of post-consumer and post-industrial plastic from the waste stream

The equivalent of over 210 million plastic milk bottles is recovered annually and given new life as our recycled plastic lumber. We demonstrate accountability to our customers by contracting with GreenCircle Certified, LLC, a third-party firm to audit and provide annual certification of our environmental claims.

On July 1, 2015 Tangent achieved Recycled Content Certification by GreenCircle. This certification qualifies and substantiates our compliance with all Federal Trade Commission (FTC) 2012 Green Guidelines so that we and our customers move forward with confidence.

Tangent is first in our industry to receive a "Closed Loop Product Certification"

Key customers and Tangent established a collaborative system whereby plastic scrap generated at our customer’s fabrication processes is returned to Tangent for reuse and recycling back into the same or similar products within our manufacturing operation. GreenCircle has audited and certified this take-back program and awarded Tangent a Closed Loop Product Certification.
