Advanced Sustainable Process Integration and Comprehensive Techno-Economic Evaluation of Polystyrene Waste Upcycling into Methanol as a Clean Alternative Fuel
This study presents an integrated and sustainable approach for the valorization of polystyrene (PS) plastic waste into methanol, contributing to circular carbon utilization and waste-to-fuel strategies. Two simulation models were developed in Aspen plus. In Case 1, PS is converted to syngas through steam gasification,...
