Plastic Waste Life Cycle Assessment
Research Guide
What is Plastic Waste Life Cycle Assessment?
Plastic Waste Life Cycle Assessment (LCA) quantifies environmental impacts of plastic materials across their life cycle from raw material extraction through production, use, and end-of-life disposal or recycling.
Researchers apply LCA methodologies to compare mechanical recycling, chemical recycling, and disposal options for plastics using databases like ecoinvent for inventory data. Studies model mass balances, energy use, and emissions for scenarios including open dumping prevalent in developing countries. Over 10 key papers since 2005, including foundational LCA work, address plastic packaging and waste management impacts.
Why It Matters
LCA results guide circular economy policies by evaluating recycling efficacy versus landfilling, as in Morseletto (2019) targets for resource recirculation with 1237 citations. They inform waste management in the Global South, where mismanagement causes contamination, per Navarro Ferronato and Torretta (2019, 2064 citations) and Abubakar et al. (2022, 631 citations). Chemical recycling assessments, like Vollmer et al. (2020, 1618 citations), support scaling beyond mechanical methods to reduce virgin plastic demand.
Key Research Challenges
Data Scarcity in Developing Regions
LCA models lack region-specific inventory data for waste fates like open dumping, leading to uncertain impact estimates. Navarro Ferronato and Torretta (2019) highlight global mismanagement issues affecting model accuracy. Abubakar et al. (2022) note inconsistencies in Global South practices.
End-of-Life Fate Uncertainty
Quantifying leakage to oceans or incineration versus recycling remains challenging due to variable collection rates. Patrício Silva et al. (2020, 1024 citations) document increased plastic pollution from pandemics complicating fates. Perugini et al. (2005, 336 citations) compare recycling options but stress fate variability.
Circularity Metrics Comparability
Diverse metrics for assessing recycling loops hinder cross-study comparisons in LCA. Corona et al. (2019, 863 citations) critically assess circularity indicators for plastics. Vollmer et al. (2020) emphasize needs for standardized chemical recycling evaluations.
