“…Biodegradable polymers offer solutions for short life-span applications, at risk of entering the environment, or where composting is desirable, such as agricultural films, packaging, and disposable cutlery [128,137]. However, a lot of uncertainties regarding biodegradable polymers remain, including (a) the increasing complexity in waste management, including the need for specific collection and composting facilities, the low volumes produced not justifying waste management efforts, the degradation of common plastics if introduced in recycling lines, and longer degradation periods and release of greenhouse gases under anaerobic conditions in landfills (likely in developing countries); (b) the presence of contaminants that may compromise compost quality or release harmful chemicals or particles to the environment, such as additives used to enhance physical properties; (c) the high costs of production coupled with ensuring the lack of degradation before use, which may compromise product shelf-life; (d) the use of agricultural land and chemical fertilizers, insecticides, and herbicides, in the case of bio-based polymers; (e) increased littering due to biodegradable claims coupled, in some cases, with low rates of biodegradation in the environment [1,48,128,135,137,139,140,141,142,143,144,145,146,147]. For example, in Thailand, LCA of water bottles reveals that cassava-based PLA bottles generally have lower environmental impacts than its fuel-based PET, with the exception of eutrophication and acidification potential caused by agricultural processes [148], whereas the PLA food trays have higher environmental impacts than PS [149].…”
