Published: Jan. 23, 2025

The buildup of abandoned plastics in the environment and need to optimize agricultural waste utilization have garnered scrutiny from environmental organizations policymakers globally. This study presents an assessment thermal decomposition date seeds (DS), polypropylene homopolymer (PP), their composites (DS/PP) through experimental measurements, machine learning convolutional deep neural networks (CDNN), kinetic thermodynamic analyses. measurements involved pyrolysis co-pyrolysis these materials a nitrogen-filled thermogravimetric analyzer (TGA), investigating degradation temperatures between 25 600 °C with heating rates 10, 20, 40 °C.min−1. These revealed two-stage process for bio-composites decrease stability pure PP due moisture, hemicellulose, cellulose content DS material. By utilizing CDNN, algorithms frameworks were developed, providing responses that closely matched (R2~0.942) data. After various modelling modifications, adjustments, regularization techniques, framework comprising four hidden neurons was determined be most effective. Furthermore, analysis temperature influential parameter affecting process. Kinetic analyses performed using Coats–Redfern general Arrhenius model-fitting methods, as well Flynn–Wall–Ozawa Kissinger–Akahira–Sunose model-free approaches. first-order reaction mechanism identified appropriate compared second third order F-Series solid-state mechanisms. overall activation energy values estimated at 51.471, 51.221, 156.080, 153.767 kJ·mol−1 respective models. Additionally, compensation effect showed exponential increase pre-exponential factor increasing values, parameters indicated is endothermic, non-spontaneous, less disordered.

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)

Comparative analysis of thermal and catalytic pyrolysis methods for converting waste plastic into fuel oil

European Journal of Sustainable Development Research, Journal Year: 2025, Volume and Issue: 9(1), P. em0278 - em0278

Published: Jan. 2, 2025

This study investigated the idea of using pyrolysis to convert plastic waste into an alternative fuel oil. The thermal and catalytic conversion polypropylene oil was investigated. catalyst used aluminum chloride on activated carbon. experiment conducted in two different phases. first phase done without a catalyst, 83.10 cm³ produced at maximum temperature 300 °C reaction time 3 hours. yield 41.55%. second carbon 108.46 obtained 2 54.23%. amount char product also determined be 0.3 g for 0.2 with catalyst. From results, is more efficient than purely pyrolysis. properties were investigated, comparison made diesel showed similar characteristics concluded that applying given products degradation plastics began lower alone. In light this, suggested as combustion incineration since it known create fewer hazardous byproducts may recover other valuable raw materials.
