陶氏化学，塑料回收新突破

Group 1 - The core viewpoint of the article highlights a significant breakthrough in a new polyurethane recycling process developed by Dow and Gruppo Fiori, which allows for the recovery of polyurethane materials from scrapped vehicles without disassembly [2][3] - The new process ensures that the purity of the waste material meets the requirements for chemical depolymerization, enabling the production of recycled polyols for new products [2] - Dow has previously made strides in the chemical recycling of polyurethane foam from scrapped vehicles, achieving a closed-loop recycling breakthrough in collaboration with Jaguar Land Rover and Adient, incorporating 20% recycled polyols into new automotive seat products [2] Group 2 - The waste material for this recycling process originates from second-hand polyurethane seat foams from Jaguar Land Rover, which are reprocessed into seat foam by Dow's MobilityScience™ material innovation [3] - Currently, Jaguar Land Rover is fully utilizing this material in its automotive seats and is conducting large-scale testing in pre-production vehicles [3] Group 3 - Dow's chemical recycling technology includes an amine-based depolymerization process that breaks down waste polyurethane into high-concentration dispersions of polyurethanes, ureas, amines, and polyols [4] - This method can recover various polyurethane foams, and the recycled polyols can be reused in multiple polyurethane materials, with up to 30% of recycled polyols being reintegrated into reaction injection molded (RIM) parts [4]
