Regarding bioplastics, the Conventions Open-ended Working Group recommends that nations clearly define and standardize the identification of bio(degradable) plastics, improve bioplastic production processes to become economically and ecologically competitive with fossil-based plastics and develop universal techno-economic analysis methodologies to quantify the environmental benefit of bioplastics179. Eng. Chem. Science 358, 868870 (2017). Consumers remain uncertain of how to deal with bioplastics after use. The former typically corresponds to readily fermentable sugars from edible polysaccharide sources, such as corn and sugarcane, and edible vegetable oils. Packaging also tends to have the shortest working life out of all industrial plastic sectors3. Progress and challenges in producing polyhydroxyalkanoate biopolymers from cyanobacteria.

Woodruff, M. A. The automotive, electronics and agricultural industries also use considerable amounts of plastics (for example, 10.1%, 6.2% and 3.4%, respectively, in the EU in 2016)2,19,21. 35, 12171256 (2010). Alternatively, PEF can be synthesized by ring-opening polymerization of cyclic PEF oligomers, as pursued by Sulzer (Switzerland), which can decrease reaction times and improve molecular weight control128,132,133.

Instead, non-isocyanate bioPUs can be made from cyclic carbonates and diamines derived from vegetable oils93,139,140,141. We address technological advances in bioplastic feedstocks and manufacturing, consider the EOL options and culminate in an appraisal of commercial and regulatory aspects. Kawai, F. & Hu, X. Biochemistry of microbial polyvinyl alcohol degradation. Technology and markets day path to the future. The remainder of the Review is organized according to the stages along the supply chain of bioplastics. Adv. Increased demand and recycling-oriented regulations might create incentives for improved PLA recycling to come online, such as chemical recycling and improved biodegradation facilities, but also pave the way for new bioplastics, such as PHAs, that are more hydrolysable and, therefore, more compatible with existing composters235 (see, for example, information on Danimer Scientifics PHA). Bio-based plastics are not, by definition, more sustainable than fossil-derived plastics. Saraci, E., Wang, L., Theopold, K. H. & Lobo, R. F. Bioderived muconates by cross-metathesis and their conversion into terephthalates. J. Appl. Many LCAs focus on carbon emissions in cradle-to-gate scenarios, often for lack of reliable data on EOL scenarios. & Huber, G. W.

Frana, D. C. et al. Sci. Educating consumers and companies towards life cycle thinking will encourage a holistic view on plastic products beyond their obvious impacts associated with the use and disposal of plastics. The threat of rising oil prices owing to a supply shortage, once advertised as the main driver for renewable-resource-based materials, has not materialized. The line of Terratek Flex the market's first biodegradable elastomer bioplastics is a good example of a biodegradable plastic which is not fully bio-based. Textiles and fibre products are also rarely recycled3. The EU has announced several plastics policies under the framework of the European Green Deal and its Circular Economy Action Plan. Polyolefins, such as PE and PP, constitute >50% of global plastics production and >90% of packaging materials142. Tailoring PBAT/PLA/Babassu films for suitability of agriculture mulch application. Green Chem. Plastic production consumes ~57% of the global oil supply and released >850 million tonnes of CO2 into the atmosphere in 2019, representing 2% of the global CO2 output45,46. & Van Es, D.

However, PLA currently lacks adequate recycling options. 5, 15811588 (2015). Gundupalli, S. P., Hait, S. & Thakur, A. Int. Plastic made from cane sugar also threatens the environment. Leakage of plastic into the environment is a central issue of inappropriate EOL management3,22. Zhu, Y., Romain, C. & Williams, C. K. Sustainable polymers from renewable resources.

Uptake and effects of microplastics on cells and tissue of the blue mussel Mytilus edulis L. after an experimental exposure. bioPE is chemically equivalent to PE and, therefore, equally processable and recyclable on existing infrastructure, including future recycling methodologies such as thermolysis142. However, the need for chemicals and more complex separation units make chemical recycling more expensive and, therefore, currently less economically competitive than mechanical recycling. Technol. For any recycling technology, including existing mechanical recycling capacities, plastic products must be designed to be recyclable, such as through the use of monomaterials rather than non-recyclable multilayers. Jarerat, A., Tokiwa, Y. Oxo-degradable plastics - conventional plastics with additives to break down faster Int. The efficiency of anaerobic digestion can be increased by including elements such as a bioreactor landfill, in which H2O is circulated to enhance microbial activities for CH4 production227.

Center for International Environmental Law (CIEL). & Bie, F. D. Life cycle impact assessment of polylactic acid (PLA) produced from sugarcane in Thailand. In thermolysis, typically polyolefins, which do not possess hydrolysable functional groups, are pyrolysed at temperatures of ~200800C (depending on the polymer and catalyst used) in the total or partial absence of O2. Polycaprolactone is a popular biocompatible and biodegradable material used in applications such as sutures and implantable drug delivery devices145,146. Chem. Express Polym.
