RASTEC is a Knoxville, Tennessee–based environmental technology company that has pioneered a breakthrough solution to one of the construction industry’s most persistent waste problems — asphalt shingle disposal. For decades, millions of tons of used roofing shingles have been sent to landfills annually, creating significant environmental and economic challenges. Leveraging our patented recycling process, RASTEC has developed a closed-loop system that recovers and refines asphalt, granules, and fibers from post-consumer shingles, transforming them into high-quality raw materials for reuse in manufacturing and infrastructure applications.

Through strategic collaborations with industry leaders such as Owens Corning, RASTEC integrates seamlessly into existing manufacturing and supply chains, enabling roofing producers to incorporate recycled content without compromising performance or quality. Our process not only diverts waste from landfills but also reduces the demand for virgin resources, lowers carbon emissions, and supports the circular economy in the building materials sector.

By combining advanced technology, proven partnerships, and a commitment to sustainability, RASTEC is redefining the future of roofing materials — turning an industry waste stream into a renewable resource and setting a new standard for environmental responsibility in construction.
