This study evaluates the life cycle assessment (LCA) of the pressolysis process for recycling glass fibres from waste composites, particularly from wind turbine blades. The pressolysis process called DEECOM®, initially developed for polymer filter cleaning, utilises repeated cycles of compression and decompression to separate fibres from polymer matrices. Three scenarios are assessed: a batch process, an improved semi-continuous process with heat recovery, and a scaled-up semi-continuous process, targeting different schemes of scale-up. Results indicate that scaling up the pressolysis process significantly reduces environmental impact, with Global Warming Potential (GWP) dropping from 95 kg CO₂ eq/kg recovered fibre in the baseline laboratory scale batch process to 2 kg CO₂ eq/kg recovered fibre in the scaled-up scenario where component capacities are increased. This represents an approximate 98% reduction per kg fibre recovered in the scaled-up scenario compared to the baseline, with the most substantial improvement achieved by increasing equipment capacity rather than the number of runs or components. The environmental impact per kilogram of recovered fibre in the best scaled-up scenario studied (2.07 kg CO₂ eq/kg) approaches that of virgin glass fibre production and landfilling (1.72 kg CO₂ eq/kg), pyrolysis (1.52 kg CO₂ eq/kg) and solvolysis (1.92 kg CO₂ eq/kg), highlighting pressolysis as a promising recycling solution. This study demonstrates the viability of pressolysis in facilitating a circular economy by reducing reliance on landfilling and virgin raw materials, contributing to a more sustainable composite material lifecycle.</p><p><strong>Graphical abstract: </strong>Anti-termite and antifungal activities assessments of pyrolysis tars from five Tunisians softwood and their relationships with their chemical composition analyzed by Gas-Chromatography.</p>","PeriodicalId":23545,"journal":{"name":"Waste and Biomass Valorization","volume":"17 6","pages":"3601-3615"},"PeriodicalIF":3.1,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13176009/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147964846","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study investigated an innovative method for valorising textile waste into cellulase, recycled fibres, and reducing sugars. Various compositions of textile waste, including 100% cotton, 60% cotton blended with 40% Polyethylene terephthalate (PET) and 100% PET, were evaluated for their suitability as substrates in submerged and solid-state fermentation processes aimed at cellulase production using <i>Aspergillus niger</i> and <i>Trichoderma reesei</i>. The results revealed that maximum cellulase production of 4.75 ± 0.11 U/mL by <i>A. niger</i> and 2.41 ± 0.06 U/mL by <i>T. reesei</i> was achieved using submerged and solid-state fermentation, respectively. After fermentation, waste fabric was used as substrate for enzymatic hydrolysis into short cotton and PET fibres for recycling purposes. The hydrolysate was analysed for separation and recyclable fibres yield. Cellulase from <i>T. reesei</i> (TCEL) demonstrated superior performance compared to cellulase form <i>A. niger</i> (ACEL) and commercial cellulase (PAKCEL) by achieving the highest separation yield of 87.0% and a recyclable fibres yield of 68.6%. This comprehensive and novel approach aims to replace today's linear 'take-make-dispose' approach with circular processes, which in turns enable a closed-loop, sustainable textile management.</p><p><strong>Graphical abstract: </strong></p>","PeriodicalId":23545,"journal":{"name":"Waste and Biomass Valorization","volume":"17 10","pages":"6047-6057"},"PeriodicalIF":3.1,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13570920/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148963712","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
