TripleW and Sulapac Pilot Chemical Recycling of Reusable Cups
TripleW and Sulapac have launched a closed-loop pilot demonstrating the commercial chemical recycling of reusable cups made from Sulapac Solid, a 100% bio-based and biodegradable material. The cups are broken down via hydrolysis into lactic acid, enabling repeated reuse without waste or quality loss, supporting EU circularity goals.
Biochemistry company TripleW has partnered with Sulapac to pilot a closed-loop chemical recycling system for reusable cups made from Sulapac Solid, a dishwasher-proof, 100% bio-based and biodegradable material designed for repeated use in demanding environments. The pilot demonstrates that used cups can be collected, ground, and broken down via hydrolysis into their building blocks, including lactic acid. This polymer-to-polymer recycling process allows the material to be reused repeatedly, eliminating waste and quality degradation. The system supports the elimination of fossil-based materials, delivers long-term cost savings, and aligns with the European Union’s circularity goals. Sulapac Solid is compatible with standard plastic production processes and is intended as a sustainable alternative to oil-based plastics at scale. The pilot highlights the potential for commercial-scale chemical recycling of bio-based and biodegradable packaging, contributing to the broader trend of increasing chemical recycling patents and investment in sustainable packaging solutions.
