Advancing Sustainable Energy: Environmental and Economic Assessment of Plastic Waste Gasification for Syngas and Electricity Generation Using Life Cycle Modeling

Sustainability, Journal Year: 2025, Volume and Issue: 17(3), P. 1277 - 1277

Published: Feb. 5, 2025

The explosion of plastic waste generation, approaching 400 million tons per year, has created a worldwide environmental crisis that conventional management systems cannot handle. This problem can be solved through gasification, which converts nonrecyclable plastics to syngas with potential applications in electricity generation and synthetic fuel production. study investigates whether production from by gasification is environmentally economically feasible. Environmental impacts were assessed life cycle assessment framework using impact approach, ReCiPe 2016, 10 midpoint/endpoint categories. Midpoint results the baseline scenario grid-mix revealed climate change (GWP) 775 kg CO2 equivalent fossil depletion (FDP) 311 oil ton waste. Meanwhile, solar showed GWP as 435 FDP 166 Switching energy cut 44% 47%, respectively. However, tradeoffs higher human toxicity (HTP) marine ecotoxicity (METP) due upstream material extraction renewable systems, Among performance drivers, inputs operating materials identified sensitivity uncertainty analyses. Syngas plant 50 day yield sales revenue USD 4.79 million, excluding 4.05 operational expenditures. Financial indicators like 2.06-year payback period, 5.32 net present value over 20-year project life, 38.2% internal rate return indicate profitability system. An external cost analysis emissions-related costs 26.43 processed, dominated NOx emissions. Despite these costs, avoided less landfilling/incineration support gasification. Gasification should promoted subsidy incentive policymakers for wider adoption integration into municipal systems. Findings show it adapted global sustainability goals circular economy principles while delivering strong economic returns. findings also contribute several Sustainable Development Goals (SDGs), instance, SDG 7 promoting clean technologies, 12 implementing economy, 13 reducing greenhouse gas (GHG)

Catalytic Strategies for the Upcycling of Polyolefin Plastic Waste

Langmuir, Journal Year: 2024, Volume and Issue: 40(8), P. 3984 - 4000

Published: Feb. 16, 2024

Chemical upgrading of waste plastics is currently one the most important methods for addressing plastic pollution. In comparison to current incineration or landfill, chemical enables utilization carbon and hydrogen elements in as resources. This process strongly relies on efficient catalysts reaction systems. Through catalyst design, can be converted into fuels chemicals under optimized conditions, extending their life cycles. this review, we systematically discuss various conversion polyolefin plastics, which account a large proportion plastics. We further explore remaining challenges future development trends field, including improving product value through engineering shifting research perspectives exploring tolerance toward impurities practical rather than using pure feedstock.
