In this article, we explored sustainable and cost-effective substitutes for pure quartz glass by utilizing rice-husk-extracted silica for wound healing applications. Two new bioglasses (rice-husk silica glass (RSG) and quartz silica glass (QSG)) were synthesized by using rice-husk extracted silica and pure quartz silica, respectively, and their physiochemical and biological properties were compared with the conventional 45S5 bioglass. Different biological assays like zone of inhibition, colony counting, and morphology analysis by electron microscopy confirmed the potent antibacterial activities of the newly developed bioglasses. Antioxidant assays and cytotoxicity assays proved that these bioglasses are biocompatible and promote normal cell proliferation. Finally, in vivo wound healing studies carried out in the rat model demonstrated rapid wound healing properties of the RSG bioglass. This study explores sustainable approaches of utilizing biomass derived silica for synthesizing bioactive glasses for biomedical applications.","PeriodicalId":100015,"journal":{"name":"ACS Sustainable Resource Management","volume":"2 2","pages":"362–373 362–373"},"PeriodicalIF":0.0,"publicationDate":"2025-02-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143496377","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}

Lactic acid solubilized chitosan made films that had a wider range of tensile properties when tuned by the glycerin concentration. Neutralizing the films led to tensile strength increasing from 16.48 to 58.95 MPa, with a loss in strain at break percent decreasing from 47.95% to 28.19%. A plasticizer bath after neutralization of a glycerin-containing film leads to an increase in tensile stress from 17.97 to 26.44 MPa. The neutralized films without a plasticizer bath show a loss from 54.94 to 42.42 MPa in 98% humidity, while the neutralized sample with plasticizer decreases from 41.10 to 8.11 MPa. Having mechanisms for tunability of the properties increases the applicability of chitosan films as sustainably produced replacements for petroleum-derived plastics in single-use packaging, textiles, and many other applications.Chitosan films made from shellfish food waste have tunable mechanical and solubility properties, leading to a wide breadth of applications.","PeriodicalId":100015,"journal":{"name":"ACS Sustainable Resource Management","volume":"2 2","pages":"294–302 294–302"},"PeriodicalIF":0.0,"publicationDate":"2025-02-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.acs.org/doi/epdf/10.1021/acssusresmgt.4c00330","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143496206","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Hand sheets containing modified precipitated calcium carbonate (MdPCC) exhibited significant improvements in tensile strength (up to 68.21% increase at 15% of 20% MdPCC loading), burst index (up to 10.51 kg/cm2), burst factor (up to 95.50), and double fold (263–3383 at 25% of 20% MdPCC loading) compared to control paper. This exceptional improvement in double fold is attributed to MdPCC’s ability to facilitate stress transfer between paper fibers, leading to a more even distribution of stress and enhanced fold resistance. RC containing different dosages of PCC were characterized by different analytical techniques in order to evaluate the effective retention of the PCC into RC and paper matrix subsequently. PCC alone causes a decrease in the strength of the paper; hence, the proposed filler may overcome this drawback. This study provides the alternative pathway to replace the high dosage of inorganic filler along with no compromise in the strength properties of the paper.","PeriodicalId":100015,"journal":{"name":"ACS Sustainable Resource Management","volume":"2 2","pages":"303–315 303–315"},"PeriodicalIF":0.0,"publicationDate":"2025-02-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143496282","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}

Its safe disposal is a massive problem that needs global strategic cognizance. The sanitary waste is mainly comprised of high molecular weight acrylate-based polymers having higher water-absorbent properties with a significant carbon atom-based cross-linked backbone. Here we have derived a workable energy storage material from menstrual sanitary waste with minimal energy input, making it environmentally viable. In this study, a rich carbon matrix was produced from pyrolysis of sanitary waste pads with KMnO4 based activation at 300 °C. The obtained carbon showed the presence of MnO moieties having desirable properties as a supercapacitor electrode. The stored energy density in the synthesized carbons was found to be 11.23 Wh kg–1 at a 0.275 kW kg–1 power density. The derived carbon shows excellent capacity retention of 84% and electrochemical stability until 10,000 cycles. These porous functional carbons produced from non-biodegradable SAPs thus make a sustainable potential resource for energy storage applications.","PeriodicalId":100015,"journal":{"name":"ACS Sustainable Resource Management","volume":"2 2","pages":"234–242 234–242"},"PeriodicalIF":0.0,"publicationDate":"2025-01-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143496241","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}
