Thesis
From polymers to rings and back again: catalytic recycling of waste oxygenated polymers
- Abstract:
- This thesis describes the chemical recycling to monomer of polycarbonates and polyesters. In particular, this thesis investigates different catalysts for the chemical recycling of CO2-derived polycarbonates and develops a new chemical recycling route for epoxide/anhydride derived polyesters. The chemical recycling of poly(L-lactide) blends to L-lactide is also explored. The poly(L-lactide) chemical recycling process is then evaluated by techno-economic analysis and life cycle assessment. This thesis explores the scale up of the poly(L-lactide) to L-lactide chemical recycling process and compares the economic and environmental impacts of the chemical recycling process to virgin polymer production.
