The renewable polyethylene furandicarboxylate (PEF) has potential to replace the fossil-based polyethylene terephthalate, but the energy-intensive production hinders wider adoption. This study shows that PEF from industrial CO2 emissions and non-food biomass can save 40.5% emissions and energy use.

Polyethylene furandicarboxylate (PEF) is considered as a renewable-based solution to its fossil-based counterpart polyethylene terephthalate (PET). However, due to its lengthy and energy-intensive production process, PEF has not been established at a commercial scale. Here we present a new study on PEF produced from industrial carbon dioxide (CO2) emissions and non-food-derived biomass to provide an alternative for PET. We assess PEF production from an energy consumption, environmental impacts and production cost point of view at an industrial scale using mass and energy balance, life-cycle assessment and payback period. The results show that emissions and energy consumption can be reduced up to 40.5% compared with PET. Abiotic depletion (fossil) (6.90 x 10(4) MJ), global-warming potential (3.75 x 10(3) kg CO2-equivalent) and human toxicity potential (2.18 x 10(3) kg 1,4-dichlorobenzene equivalent) are the three most substantial impacts in producing one tonne of PEF. By applying optimal design and mature technology, PEF produced from industrial CO2 and biowastes could be a feasible and competitive substitute for PET and other materials.
