Pyrolysis of municipal solid waste: A kinetic study through multi-step reaction models

Waste Management, Journal Year: 2023, Volume and Issue: 172, P. 171 - 181

Published: Nov. 1, 2023

The present study endeavors to establish a comprehensive kinetic analysis of Municipal Solid Waste residue pyrolysis. As the sample exhibits four distinct degradation stages, it has been carried out by adopting multi-step process behavior. Different approaches have compared, including five isoconversional methods (Kissinger-Akahira-Sunose, Ozawa-Flynn-Wall, Starink, Friedman and Advanced integral Vyazovkin), Mathematical Deconvolution Analysis, Independent Parallel Reaction Model. focuses on two active pyrolysis steps, first one corresponds biomass components between 150 400 °C, with decomposition peak 300 350 whereas second plastic fraction temperature ranging 520 °C. activation energy values obtained from different for both steps are estimated at 240 250 kJ/mol, respectively. It was observed that obeys third-order model, while follows first-order model. analytical main stages allows identification semi-quantification compounds produced during municipal solid waste Through pyrolysis, determined up 64 % hydrocarbons produced, which 24 correspond aromatic compounds. Meanwhile, 20 oxygenated were obtained, ketones, furans, acids being most predominant families.

Valorization of Wood Residues from Vegetation Suppression during Wind Energy Plant Implementation and Its Potential for Renewable Phenolic Compounds through Flash Pyrolysis: A Case Study in Northeast Brazil’s Semi-Arid Region

Forests, Journal Year: 2024, Volume and Issue: 15(4), P. 621 - 621

Published: March 29, 2024

In the past few years, wind power has become a viable alternative in Brazil to diversify energy mix and mitigate pollutant emissions from fossil fuels. Significant generation potential is inherent Brazilian Northeast state of Rio Grande do Norte, due prevailing strong winds along coastline elevated regions. However, clean renewable may lead biodiversity impacts, including removal native vegetation during plant construction operation. This case study explores flash pyrolysis-based valorization three commonly suppressed species, namely Cenostigma pyramidale (CP), Commiphora leptophloeos (CL), Aspidosperma pyrifolium (AP), farm situated within Mato region Norte State. The centers on determining their bioenergy-related properties assessing for producing phenolic-rich bio-oil. investigation wood residues as sources high-value chemicals, specifically phenolic compounds, was conducted using micro-furnace type temperature programmable pyrolyzer combined with gas chromatography/mass spectrometry (Py–GC/MS setup). range higher heating values observed 17.5–18.4 MJ kg−1, highest value attributed AP residue. bulk density ranged 126.5 268.7 kg m−3, while ash content, volatile matter fixed carbon lignin content were respective ranges 0.8–2.9 wt.%, 78.5–89.6 2.6–9.5 19.1–30.6 wt.%. Although energy-related signifying resources are evident, applicability bioenergy sector can be expanded via pelleting or briquetting. Yields compounds exceeding 40% pyrolysis products CL at 500 °C make them favorable bio-oil production. findings this endorse utilization resulting suppression installation plants feedstocks sustainable compounds. presents solution addressing regional environmental concern following principles green chemistry.

Pyrolysis of mixed contaminated plastic wastes: Assessing the influence of polymers composition, temperature and residence time

Waste Management, Journal Year: 2025, Volume and Issue: 201, P. 114793 - 114793

Published: April 14, 2025

The European Union's recycling objectives of 50 % for packaging by 2025 and 55 2030 are still far from the current rate 37.8 %. Thermochemical via pyrolysis might improve recovery rates, especially challenging post-consumer dirty contaminated plastics. Many studies focus on virgin plastics artificial mixtures these to simulate real-world mixed plastic waste scenarios. This study examines a sample pre-sorting an Italian composting plant represent real within collection chain. contains plastics, organics, paper, others, with making up 72.18 sample, primarily identified as LDPE, PP, HDPE. were tested individually mixture, mirroring concentrations observed original in bench-scale semi-batch reactor at varying temperatures (420 °C, 470 520 °C) residence times. analysis indicated that temperature time considerably influence product yields composition, although has more dominant effect.
