![]() ![]() In the first case, the scenarios most often compared have been landfill disposal and mechanical recycling. LCA studies of PET consist largely of two segments: final destination of post-consumer PET, comparing recycling with other options (incineration, landfilling) and alternative materials, comparing PET with other polymers or materials such as glass and aluminum cans. The main purpose of this paper is to present an overview of LCA of PET, mainly for packaging. A review is needed to gain a clear view of the accumulated knowledge, scientific trends and what remains to be done. Life cycle assessment (LCA) is a common technique to evaluate the environmental impact of poly(ethylene terephthalate) (PET) packaging.
