COMPANY

Sixone’s mission is to enable a world where blended plastics products can be circularly recycled back into existing supply chains instead of being sent to landfill. Sixone is a leading technology startup company developing advanced recycling technologies for blended plastics and plastic-based products. The technology applies process digitalization and advanced analytics to build a recycling system to enable efficient plastics recycling. Our goal is to revolutionize the economics of recycled materials through innovative processing and materials technologies.
