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)

Microplastics: Challenges, toxicity, spectroscopic and real-time detection methods

Applied Spectroscopy Reviews, Journal Year: 2024, Volume and Issue: 59(9), P. 1183 - 1277

Published: Feb. 8, 2024

Plastics are in high demand for various uses worldwide because of their low cost, versatility, lightweight, density, flexibility, strength, and durability. An increase single-use plastics ineffective solid waste disposal recycling strategies have resulted a global microplastic (MP) pollution epidemic, with negative implications the ecosystem public health safety. Analytical methods, including thermogravimetry chromatography, been developed to detect MPs. Nevertheless, molecular spectroscopy methods such as Near Infrared (NIR), Fourier Transform (FTIR), Raman, fluorescence MP analysis gained attention recent years due rapidity, accuracy, portability spectrometers. This review article provides in-depth coverage survey current literature on challenges, toxicity, sample pretreatment, spectroscopic (Fluorescence, FTIR) real-time (satellite imagery, unmanned aerial vehicles, aquatic drone technology) detection methods. Machine learning, micro-hyperspectral imaging, chemometrics approach detections discussed. The future directions, prospects decreasing

Drinking Water Network as a Potential Pathway for Micro- and Nanoplastics Exposure to Human: A Mini Review

Water, Journal Year: 2025, Volume and Issue: 17(8), P. 1188 - 1188

Published: April 15, 2025

The risk of human exposure to micro- and nanoplastics (MNPs) has received increasing attention in recent years. Consumption drinking water is a significant route MNPs. While previous studies focus on MNPs treated wastewater or final effluent, research addressing networks (DWNs) as potential secondary sources remains sparse. However, how DWN, critical component transporting from treatment plants consumers, contributes contamination underexplored existing studies. We extracted keywords reviewed literature using bibliometric methods conducted correlation analyses, revealing four clusters: baseline detection, health assessments, nanoplastic, treatment. abundance DWN ranged 0.01 1.4 items/L. varied between 679.5 4.5 × 107 items/kg when calculated based sample mass (in scales debris). Based the shape polymer composition MNPs, strongly suspected contribute tap water. also main mechanisms for formation release pipelines, including mechanical forces, hammer effects, chemical aging. Our review highlighted current gaps MNP DWN. It will understanding contribution provide framework future monitoring efforts.
