Life Cycle Assessment of Compostable and Biodegradable Polymers

Poly(butylene succinate) can be molded on conventional thermoplastic processing equipment, including blown film, mono-filament extrusion, blow molding, and injection molding. PBS pellets should be dried to a water content of less than 0.1% to prevent hydrolysis (Xu and Guo 

Poly(butylene succinate) can be injection molded at barrel temperatures between 140°C and 160°C, injection pressure of 90 bar, and mold temperature of 20°C (Qi et al. 2013). 

4 LIFE CYCLE ASSESSMENT OF COMPOSTABLE AND BIODEGRADABLE POLYMERS 

The environmental effects of producing PH A, TPS, and PL A are provided from three sources mentioned previously. The first LCA source for PHA was created with simulation of producing P(3HB-3Hx) from 

The third source of LCI data for starch-based polymers was produced for a Swiss Federal Agency for the Environment (Patel et al. 2003). The assumptions were cradle-to-gate LCI and end-of-hfe options are ignored. The functional unit was 1 kg of plastic.
