Who We Are

At RASTEC, we are redefining the future of roofing waste management. Headquartered in Knoxville, Tennessee, we bring more than 15 years of proven expertise in handling, processing, and recycling over 1 Million tons of asphalt shingles. What began as a vision to solve one of the construction industry’s largest waste problems has grown into a patented, closed-loop recycling process that is setting a new global standard for sustainability.

Our Mission

Every year, millions of tons of shingles end up in landfills, taking centuries to break down and contributing to mounting environmental concerns. At RASTEC, our mission is simple yet ambitious: to eliminate shingle waste from landfills by transforming it into valuable new resources and renewable energy.

Through innovation, engineering excellence, and a commitment to circular economy principles, we’ve developed a closed-loop system that not only diverts shingles from landfills but also produces raw materials that can be reintroduced into the manufacturing cycle—creating new shingles, clean energy, and other high-value outputs.

Our Experience

With a legacy of over a decade of industry leadership, RASTEC has successfully processed over a million tons of roofing materials. Our expertise spans every stage of the recycling lifecycle: from logistics and collection to processing, refining, and redistribution. This hands-on experience, coupled with our proprietary technology, positions RASTEC as a trusted partner for manufacturers, municipalities, contractors, and communities nationwide.

Our Technology

At the heart of our success is our patented closed-loop recycling process. Unlike traditional methods that downcycle shingles into limited-use road materials, our approach enables full material recovery—unlocking energy and raw resources while producing zero harmful emissions. This breakthrough not only ensures environmental responsibility but also opens the door for exponential growth as demand for renewable energy and sustainable construction materials accelerates.

Our Vision

RASTEC is built for scale. With the groundwork already in place, our model is designed for rapid expansion across the United States and beyond, tackling one of the most persistent challenges in the construction and energy sectors. By combining environmental stewardship with economic opportunity, we are proving that sustainability and profitability can go hand in hand.
