Pyrolysis offers significant potential for recovering resources from non-degradable textiles (e.g., polyester). However, comprehensive studies on product distribution and the release of hazardous components across diverse textile types remain limited, which restricts the development of high-value resource recovery strategies and leads to potential environmental and health risks. This study systematically investigated the fast pyrolysis (550 °C) characteristics of five pure textiles—cotton (C), wool (W), nylon (N), polyester (T), rayon (R)—and one mixed textile (MT). The results revealed distinct product profiles for different textile types. Cotton-derived bio-oil exhibited high content (83.61 %) of light hydrocarbons (<C10), making it suitable for use as liquid fuel after simple acid removal. Wool pyrolysis generated complex bio-oil requiring secondary cracking. Synthetic fabrics (N, T, R) produced bio-oils with substantial corrosive carboxylic acids (e.g., benzoic acid), necessitating esterification pretreatment for fuel use. MT pyrolysis yielded nitrogen-rich bio-oil (74.77 % N-compounds) containing 37.35 % caprolactam, highlighting its value as a chemical feedstock but requiring carbon black separation from the particulate matter (PM). PM analysis identified viscosity-driven formation in cotton and tar/soot dominance in synthetics. This study provides critical insights into tailoring pyrolysis protocols to specific textile wastes, thereby advancing sustainable resource recovery while mitigating corrosion and pollution risks associated with hazardous by-products.</div></div>","PeriodicalId":23969,"journal":{"name":"Waste management","volume":"211 ","pages":"Article 115293"},"PeriodicalIF":7.1,"publicationDate":"2026-01-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145737743","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Electrical resistivity tomography (ERT) and time-domain induced polarization (IP) surveys were performed along two survey lines for mapping leachate distribution.

A comparison of ERT and IP profiles obtained 20 years apart suggested significant leachate presence and varying degradation rates within the waste body, even years after waste disposal activities had ceased. Geoelectrical data were grouped into seven clusters, which were interpreted based on material type (soil and MSW), degree of saturation (partially and fully saturated waste), and organic matter content (from dry to biogeochemically active zones). The SPT tests confirmed complex fluid distribution by revealing leachate ejection and gas emissions at specific regions of the landfill showing low resistivity (below 10 Ωm) and moderate to high chargeability (from 5 to 60 mV/V) and normalized chargeability (from 1 to 7 mS/m).

Conventional approaches rely on direct sampling, which is both time-consuming and costly. This study presents an accurate and stable Genetic algorithm-based inverse method for estimating municipal solid waste composition without sampling. The method estimates municipal solid waste composition from measurable parameters, including flue gas, working fluid, ash, and leachate, using a genetic algorithm for accurate and stable estimation without physical sampling. The method’s accuracy and stability are validated through numerical simulation experiments involving five distinct municipal solid waste compositions. Data from direct problem simulations, perturbed by random errors, serve as inputs for the genetic algorithm-based inverse solution. Results indicate that the inverse solution is stable. Results indicate that the inverse solution is stable and accurately reproduces the average composition of the five municipal solid waste samples used in the direct method. The results reveal that the estimated composition of municipal solid waste closely matches actual values, demonstrating the feasibility of this genetic algorithm-based approach. The modified methodology is employed at the Aradkooh waste-to-energy power plant in Tehran, Iran. The findings from the Aradkooh power station indicate that the carbon, oxygen, hydrogen, sulfur, moisture, and ash content of municipal solid waste are 27.14, 33.29, 3.16, 0.3, 15.41, and 20.21 percent, respectively. The novelty of this study lies in stabilizing the inverse problem by increasing the number of equations.

Results show that the ESLR route increases lithium recovery to 61.9 % in experiments, with higher product quality. Simulation-based analysis showed a 5.7 % reduction in climate change impact per kg black mass treated compared to the reference route.
