ENCORE - Energy Catalysis Process Reaction Engineering Àrees temàtiques de la UPC::Enginyeria química Process simulation Circular economy Electrification Plastic waste Sustainable development Chemical recycling A new process design for plastic waste gasification and conversion to methanol is described in its main elements. An electrification approach is used to maximize the CO2 credit generation of the plant. The overall process yields are described for three different feedstocks made of HDPE, PP, and PS. Electrical consumption is broken down by unit contributions to identify process bottlenecks. Preliminary profitability analysis is done with and without accounting for the possibility of selling credits CO2 showing that the process is unprofitable unless CO2 credits are accounted for. Depending on the feedstock, CO2 credits between 89.5 and 103.2 €/t are shown estimated to reach a payback time of 3.5 years without accounting for labor and taxes.
