Using data from a small-scale bioplastic facility, hotspots affecting the environmental performance of the process were determined. As a main result, polybutylene adipate terephthalate (PBAT) polyester contributes around 50 % of the gross impact when producing retarch blown (RB)-grade products. The results concluded that bioplastics decrease carbon footprints and fossil energy use compared to fossil plastics, saving 1.63–2.10 kg CO 2 eq FU −1 and 29.6–76.1 MJ eq FU −1 , respectively. This work analyzed the environmental impact of six end-of-life (EOL) scenarios as potential bioplastic disposals of the current waste management policy in the Republic of Korea. The scenarios with the lowest CO 2 emissions involved energy credits through grid electricity substitution, such as incineration with energy recovery (2.88 kg CO 2 eq FU −1 bioplastic) and anaerobic digestion (2.74 kg CO 2 eq FU −1 bioplastic). This LCA aims to support the future development of starch-based bioplastics by determining that the composition of the PBAT plasticizer has an important role in the carbon footprint. Additionally, this research demonstrates the most optimal disposal method to reduce greenhouse gas (GHG) emissions and its potential alternative to fossil-based plastics. • End-of-life based on energy recovery demonstrated the lowest carbon footprints. • Biological disposal methods are appealing due to potential environmental credits. • Co-polyesters drastically influenced the environmental performance of bioplastics. • Reducing PBAT content is beneficial regarding the environmental costs. • Bioplastics save CO 2 emissions and energy demand compared to fossil counterparts.}, journal={Journal of Cleaner Production}, author={Poveda-Giraldo, Jhonny Alejandro and Yoo, Seongyon and Yoo, Seunghyun and Kim, Inho and Lan, Kai and Venditti, Richard and Park, Sunkyu}, year={2025}, month={Jul} }

However, at least part of that amount has higher-valued uses, including being made into durable products, thereby keeping their carbon content from contributing to global warming. This review considers circumstances under which it may be advantageous to use biomass resources, either alone or in combination with other renewable energy technologies – such as solar and wind energy – to meet society’s energy needs, especially for electricity, heating, and transportation. There is a rapidly expanding pool of published research in this area. To slow climate change, rapid maturation of the most promising technologies is needed, followed by their widespread and early implementation. Of particular interest are synergistic combinations of technologies, including the use of solar energy and biomass together in such a way as to provide hydrogen, heating, and electricity. Another need is to use biomass to make high-energy-density liquid fuels, including aviation fuels, diesel, and naphtha. Although some proposed schemes are complicated, biomass is expected to be gradually implemented as a growing component of installed renewable energy capacity in the coming years.}, number={3}, journal={BioResources}, author={Hubbe, Martin A. and Cho, Seong-Min and Poveda-Giraldo, Jhonny Alejandro and Garcia-Vallejo, Maria Camila and Yao, Yuge and Li, Fanxing and Park, Sunkyu}, year={2025}, month={May}, pages={8023–8092} }
