Rooted in Lancaster County, Pennsylvania, Sustainable Composites upcycles discarded leather scrap into reusable material that can replace traditional leather in products such as luggage and furniture. Its founders—scientists, material engineers, and outdoor-industry executives—developed a process that keeps leather waste out of landfills while helping manufacturers build circularity into their supply chains. The company also processes customers’ cutting-room and post-consumer leather scrap into new material tailored to specified properties.
