Depolymerisation proved to be an appropriate recycling solution for polystyrene
Depolymerisation helps to eliminate post-consumer waste and recover valuable resources
Depolymerisation produces less CO2 than conventional styrene production
INEOS Styrolution, the global leader in styrenics, reports final results of the research project ResolVe. ResolVe was granted a funding from the German Federal Ministry of Education and Research (BMBF) to explore the recycling of polystyrene1. The project proves the feasibility of post-consumer waste becoming a valuable feedstock, thus creating a circular economy for polystyrene. The project also included a commercial and an ecological evaluation of the recycling process.
