BioPackLCA – Closing the gap : Extending LCA to reflect the sustainability contributions of bio-based packaging
AI summary Read the abstract
This report examines gaps in life cycle assessment (LCA) methodology for bio-based packaging, proposing enhanced impact categories to better capture littering potential and microplastic generation potential compared to conventional plastics. It aims to enable fairer environmental comparisons between bio-based and petroleum-based packaging materials.
Existing LCA methods (especially impact categories considered) do not always include some of the environmental interventions that are unique to bio-based materials. Subsequently, this report to investigates areas where LCA impact assessment methodology can be enhanced or expanded in order to fully account for the environmental advantages and disadvantages of bio-based packaging materials. The work focuses on impact assessment areas most pertinent to three of the highest-profile environmental policy objectives of the day, i.e. climate change, single-use plastics and microplastics generation. Subsequently, recommendations are made with regards to the application of the global warming potential impact category when conducting LCA studies comparing bio-based and other packaging materials, and proposals are presented for simplified impact categories for littering potential and microplastics generation potential.

AI summary Read the abstract
This review examines the full environmental impact of plastics from production through disposal, noting that life cycle assessments often produce unexpected results when comparing bio-based and petroleum-based plastics. A major gap exists because microplastic pollution is not yet factored into these environmental assessments, despite growing evidence of its ecological harm.
Life Cycle Assessment (LCA) of Bioplastics
AI summary Read the abstract
Researchers conducted life cycle assessments of multiple bioplastic types — including PLA, PHA, and starch-based polymers — finding that while bioplastics generally reduce fossil resource depletion compared to conventional plastics, their environmental benefits vary considerably depending on feedstock, production process, and end-of-life scenario.
Integrating impacts of microplastics in Life Cycle Assessment modelling: the work of the MarILCA group
AI summary Read the abstract
This paper describes the work of the MarILCA group to incorporate microplastic impacts into Life Cycle Assessment (LCA) modeling, which evaluates the environmental footprint of products and processes. Currently, most LCA studies ignore plastic leakage to the environment, creating a blind spot for the real-world impacts of plastic production. Integrating microplastic impacts into LCA could help guide more sustainable material choices and policy decisions.
