Life Cycle Assessment in a Nutshell—Best Practices and Status Quo for the Plastic Sector
This paper reviewed life cycle assessment (LCA) best practices as applied to the plastics sector, aiming to make LCA methodology more accessible to non-experts and improve environmental decision-making across the plastic value chain.
The capabilities and deficiencies of life cycle assessment to address the plastic problem
This review critically evaluates the capabilities and limitations of life cycle assessment (LCA) as a tool for understanding the full environmental impacts of plastics across their supply chain, from production through end-of-life disposal. The authors argue that LCA can contextualize plastic impacts relative to alternative materials and reveal invisible environmental costs throughout the plastic life cycle, while also identifying key deficiencies in current LCA methodology for addressing plastic pollution.
Study of the Environmental İmpact of Petroleum Product Waste Generated During Polyethylene Production at the SOCAR Polymer Plant
Researchers analyzed the environmental impact of polyethylene production at the SOCAR Polymer plant, examining the morphological composition of waste generated during synthesis, polymerization, and granulation stages and quantifying emissions of petroleum product waste with implications for microplastic pollution.
A critical review on plastic waste life cycle assessment and management: Challenges, research gaps, and future perspectives
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.

Researchers applied life cycle assessment to common single-use plastic products in Sri Lanka, quantifying their environmental impacts across production to disposal and providing evidence-based recommendations to guide national plastic pollution policy.
The geopolitical economy of Thailand's marine plastic pollution crisis
Researchers examined the geopolitical and economic factors driving Thailand's status as one of the world's largest contributors to ocean plastic pollution, finding that governance failures, economic development pressures, and global plastic supply chains are key structural drivers that environmental management has not adequately addressed.
Polymer prioritization framework: A novel multi-criteria framework for source mapping and characterizing the environmental risk of plastic polymers
Researchers developed a multi-criteria framework for ranking the environmental risk of plastic polymers, finding that polyvinyl chloride, polypropylene, and polystyrene posed the highest risk, with packaging and construction sectors as dominant sources.
Plastic packaging flows in Europe: A hybrid input‐output approach
Researchers modeled plastic packaging material flows across the EU using a hybrid input-output approach, mapping supply chains by polymer type, packaging form, and application category to reveal that packaging represents a major fraction of plastic consumption with significant gaps in end-of-life recycling infrastructure.
Expanding plastics recycling technologies: chemical aspects, technology status and challenges
This review examined the full life cycle of plastics and evaluated options for managing plastic waste, with a focus on chemical recycling technologies. The study suggests that overcoming barriers to industrial chemical recycling could open new opportunities for reducing plastic pollution.
Assessing the environmental footprint of recycled plastic pellets: A life-cycle assessment perspective
This study used life-cycle assessment to evaluate the environmental impact of producing recycled plastic pellets from waste polyolefin plastics. While recycling reduced carbon emissions compared to making new plastic, the process still required significant energy, especially when solvent recovery was maximized. The research is relevant to the microplastics problem because it shows that even recycling processes need optimization to truly reduce the environmental footprint of plastic waste.
Comparative Analysis of Environmental, Economic, and Social Criteria for Plastic Recycling Technology Selection in India, Sri Lanka, Pakistan, and Thailand
This study surveyed stakeholders in four Asian countries about criteria for selecting PET plastic recycling technologies, finding that environmental and economic factors were rated highest. Improving PET recycling capacity is critical for reducing plastic waste that ultimately becomes microplastic pollution.
CO2 Emissions from Plastic Consumption Behaviors in Thailand
This paper is not about microplastics; it surveys plastic consumption behavior in Thai households and estimates the resulting CO2 emissions from end-of-life plastic disposal, focusing on climate change implications.
Resource Intensity Analysis of Producing 21 Types of Plastic in Terms of Mining Activity
Researchers calculated the cradle-to-gate resource intensity of producing 21 types of plastics using total material requirement under a life cycle framework, finding that resource use varies by up to approximately 10 times depending on plastic type. Applying these findings to material flow analyses revealed that natural resource extraction exceeds the direct weight of plastic by more than 20 times, and that a positive correlation generally exists between greenhouse gas emissions and resource use across plastic types.
Sustainable Management of Organic Waste and Recycling for Bioplastics: A LCA Approach for the Italian Case Study
Researchers used life cycle assessment to evaluate the environmental trade-offs of collecting organic waste for biodegradable plastic production in Italy, finding that the system could reduce fossil resource use but that impacts depended heavily on collection efficiency and the end-of-life pathway chosen.
