Building now for generations to come. Ensuring our impact on the world is a positive one, that what we leave behind is better, truer than what we found.

Timeless Beauty 
and Performance.

While homeowners want the beauty of decking, you want to trust that what’s underneath is meant to last and is kind to our planet. Like homeowners, builders and contractors also want a durable product that withstands Mother Nature and human wear-and-tear like no other material.

We’re doing more than 
making building materials

In 2004, a mistake during an experiment resulted in the creation of a new material made from 97 percent post- consumer recycled materials such as plastics and glass. 

Founder, Paul Schmitt, then spent years researching and experimenting to refine the process and formula, today known as Envirolastech, a thermoplastic technology that offers an alternative to wood, concrete and other composite materials, in an unlimited variety of products and applications.

Our Mission: Clean Up the World

Our Vision: Visibly reduce landfills while creating more 
stable, environmentally friendly ways to live

What’s In Our Name?


A desire to clean up the earth drove us to create this company and the Envirolastech material. It infuses our products, our processes and our goals for the future.


Rounds of testing have confirmed that Envirolastech material is more durable, longer-lasting and has higher tensile strength than other building materials.


We are harnessing technology for the good of the earth. It is our unique, proprietary technology that allows us to create a greener, longer-lasting building material.

Superior Performance

Why does this matter?

Woodfill and decking materials that contain it, are biodegradable and will eventually break down overtime. If the surface gets chipped, dented or cracked, the core becomes susceptible to water and pest damage – all of this weakening the overall performance of your product. 

Envirolastech decking is free of biodegradable ingredients. Just one of many reasons it is the stronger, longer lasting choice.

Another common thermoplastic used in building materials is Polyvinyl chloride (PVC). But, it’s highly toxic chemicals used in production and processing are detrimental to our environment – making Envirolastech decking a greener, eco-restorative choice because it’s free of toxic chemicals. And if desired, can be 100% recycled! (And once its useful life is finished, it can be recycled at Envirolastech and made into something new.)
