ABOUT US
We believe plastic can have a better ending.
RNG Plastics is pioneering a new category of renewable plastics designed to preserve the performance and economics manufacturers depend onâwhile creating a practical pathway from plastic waste to Renewable Natural Gas and back into productive use.
The world has spent decades trying to solve plastic waste. It hasnât worked.
Plastic is extraordinarily usefulâand extraordinarily persistent. Mechanical recycling has an important role, but it cannot economically or practically handle most plastic waste. Recycled materials can cost more, perform differently, require reformulation, and degrade through repeated recycling cycles.
Meanwhile, the overwhelming majority of plastic still reaches its end of life without becoming new plastic.
We believed there had to be another path.
A different approach to circularity
RNG Plastics combines patented materials science, independent testing and verification, and digital traceability to create a practical pathway for conventional fossil-fuel plastics to become renewable.
Manufacturers incorporate only 0.5% of our proprietary EPS Resin⢠into compatible plastics during normal production. The resulting RNG Plastics retain the performance manufacturers require while enabling controlled conversion at end of life in regulated landfill environments.
The resulting biogas can be captured, processed into Renewable Natural Gas, and returned to the energy and materials economyâcreating a circular pathway that works with the infrastructure society already has.
We Donât Think Sustainability Should Require Compromise
For decades, manufacturers have been asked to choose between performance, economics, and sustainability.
We donât think they should have to.
RNG Plastics was built around a different premise:Â the sustainable solution has to be a better business solution, too.
That means preserving product performance. Minimizing manufacturing changes. Working with existing supply chains. Providing defensible evidence for environmental claims. And creating measurable economic value rather than simply adding another sustainability cost.
It's more than a resin - it's an ecosystem
Meet The Team
Bob DeMatteis
Founder
Bob DeMatteis is an inventor and internationally recognized expert in renewable plastics whose work has resulted in more than 40 U.S. patents covering advanced plastic materials and environmental technologies.
He founded RNG Plastics to commercialize a fundamentally different approach to plastic circularity: preserving the performance and utility of conventional plastics while enabling a renewable pathway at the end of their useful life.
DeMatteis is the inventor behind RNG Plasticsâ proprietary EPS Resin⢠technology, which enables compatible fossil-fuel plastics to undergo controlled conversion in regulated landfill environments, where resulting biogas can be captured and processed into Renewable Natural Gas.
His work brings together decades of materials innovation around a singular objective: making plastic compatible with a truly circular materials economy.
