Life Cycle Assessment of Plastic Waste Incineration At End-of-life
AI summary Read the abstract
Life cycle assessment of incinerating five major plastic types (PET, PE, PP, PS, PVC) shows that environmental impacts are primarily driven by pollution-control inputs required during incineration, while energy recovery substantially reduces those impacts under reduced-burden allocation. The findings provide decision-makers with plastic-type-specific environmental profiles to optimize waste management strategies and identify which plastics are more suitable for incineration versus alternative disposal routes.
The ongoing development and expanding use of new plastic polymers have intensified global challenges in plastic waste management. Incineration has gained rapid popularity due to its advantages of significantly reducing waste volume and utilizing the high calorific value of plastics for thermal energy and electricity generation; however, these benefits come with environmental trade-offs. Because conventional incinerators process mixed waste streams, the net environmental impact attributable specifically to plastic waste and to individual plastic types has remained unclear. This study therefore conducts a comparative assessment of five major plastics: PET, PE, PP, PS, and PVC. Two extended system boundaries are examined: one incorporating pollution-control measures necessary to comply with U.S. regulatory standards, and the other integrating energy recovery. Using a functional unit of 1 tonne of plastic waste, inventory analysis and impact assessment were performed using the TRACI 2.2 method. Results indicate that environmental impacts are primarily driven by the input inventories required for pollutant control during incineration of each plastic type, while energy recovery substantially reduces impacts when reduced-burden allocation is applied. Ten impact categories were evaluated to determine the relative viability of each plastic type. These findings provide decision-support for local authorities and stakeholders by identifying which plastic materials may be more suitable or less desirable for incineration, depending on regional environmental priorities and vulnerabilities.

Researchers investigated the vertical distribution of microplastics in open ocean water columns at stations across the North Atlantic, finding that particle concentrations were highest in subsurface waters rather than the surface mixed layer. Biofouling and association with marine snow were identified as mechanisms driving downward flux of buoyant polymers in the water column.
Life cycle assessment of plastic waste end-of-life management: a systematic review
AI summary Read the abstract
Researchers systematically reviewed 2019–2025 life cycle assessment literature on plastic waste end-of-life management, finding that global warming potential dominates as the studied impact category and that recycling, incineration, pyrolysis, and landfilling each carry distinct environmental trade-offs, with significant gaps remaining in geographic coverage and functional unit standardization.
Environmental trade-offs in plastic waste management pathways: A critical synthesis of comparative life cycle assessment studies
AI summary Read the abstract
This review of existing studies finds that traditional recycling (melting and reusing plastic) is generally the cleanest way to handle plastic waste, while burning it or dumping it in landfills is worse for the environment. Importantly, most studies focus only on climate impact and rarely examine how plastic waste disposal affects human health or microplastic pollution, meaning we still don't fully understand these risks.
