Alternative building blocks sources for poly (ethylene terephthalate): A short review with socio-economical points of view

چکیده
The objectives of circularity are often focused on recycling, but combining use alternative building blocks such as bio-sourced ones for virgin materials with ability recycling seems to be a relevant challenge. Unfortunately, the volumes rather new bio-based plastics, Poly (lactide) (PLA), seem too low allow development chains in next years. Therefore, these bio-plastics not likely recycled at large scale, reducing their interest when considering whole life cycle. Nevertheless, continuing produce petroleum-based plastics and searching way recycle them self-sufficient solution. Indeed, order reconciliate strategy is focus production conventional poly (ethylene terephthalate) (PET), from renewable resources while ensuring existing chains. In this context, review focuses sources PET, which developed. Although still produced small quantities, some block have been able establish themselves industrial landscape. there little industrialization synthons quantities. Most discoveries confined laboratory studies pilot tests part them. It should emphasized that, even if already commercialized, research active aim improving yields, discovering cleaner catalysts, energy consumption. describes routes only technological also socio-economical points view discussion potentials limits. different proposed display promising advantages improved by studies. producing polymers large-scale could lead problems access resources.
