The present work employs a low-carbon circular bio-economy by combining RHC technology for the valorization of SLP through pectin extraction. Numerical simulations using computational fluid dynamics revealed the optimum geometrical parameters for the cavitation generation unit to be of semi-circular shape, 9 mm depth, 10 mm diameter with 504 units. Box–Behnken Design of pectin extraction using numerically optimized RHC indicated that time of 32.8 min, rotational speed of 1800 rpm, solid: liquid ratio of 1:30, at fixed DES: water ratio of 1:6, yielded maximum pectin of 32.89 % with 88.24 % degree of esterification. The Analysis of Variance assessment indicated the influence of process parameters in the order rotational speed&gt;extraction time &gt; solid-to-liquid ratio. The physicochemical characterization of the RHC-extracted pectin observed similar morphology and structure to that of commercial pectin. The process developed ensured higher pectin yield having high thermal stability but resulted in possible truncation of pectin chains into oligomers with molecular weight 60.04–901.10 kDa. The scale-up study has demonstrated the feasibility of an industrial scale process and its cost-effective aspects with a significant return on investment within a year.</div></div>","PeriodicalId":8947,"journal":{"name":"Bioresource Technology Reports","volume":"33 ","pages":"Article 102517"},"PeriodicalIF":0.0,"publicationDate":"2026-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145972932","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Converting Polyethylene terephthalate (PET) into drop-in chemicals could increase the process economic viability and interest in recovery, offering a cleaner route for repurpose of plastic waste.

This review therefore provides a comprehensive analysis of the removal performances, influencing factors, and underlying mechanisms of antibiotics and ARGs in sludge HTC and CTC. Overall, HTC, performed at sustained high temperature (&gt;80 °C for 5-7d), achieves nearly complete removal of antibiotics, while removal rate is less than 70 % in CTC. Microbial biodegradation is the primary removal pathway in both processes, but HTC enhances bioavailability of antibiotics through thermal transformation and desorption. For ARGs and mobile genetic elements (MGEs), HTC effectively reduces their abundance mainly via shaping host bacteria succession, which is closely related to higher temperature and C/N, and neutral pH. ARGs dissemination could also be controlled in HTC by inhibiting MEGs-induced horizontal gene transfer, and alleviating co-selective pressures from antibiotics and heavy metals. In contrast, CTC often leads to ARG rebound due to bacterial regrowth and enhanced MGEs levels. Finally, future research directions are proposed to advance HTC application and risk assessment.</div></div>","PeriodicalId":8947,"journal":{"name":"Bioresource Technology Reports","volume":"33 ","pages":"Article 102549"},"PeriodicalIF":0.0,"publicationDate":"2026-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145922219","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Special emphasis is placed on the degradation behaviour of these plastics in composting sites, marine environments, and landfills, along with the factors governing these processes.
