Green liquor dregs (GLD), an industrial alkaline solid waste generated by pulp and paper companies, can capture CO2 through aqueous direct carbonation. However, aqueous carbonation requires high water consumption. To address this, an alkaline wastewater from the pulp and paper industry was used as an alternative to fresh water, reducing the need for additional water consumption. In this work, the absorption capacities, reaction yield, and physicochemical characteristics of the samples were studied. A 3D-printed reactor, designed by our research group, was used to take advantage of bubble turbulence for mixing the aqueous and gaseous phases, thereby reducing electricity consumption. The solids before and after carbonation were analyzed using X-ray diffraction and scanning electron microscopy. The absorption capacity for GLD in deionized water was in the range between 5.92 and 14.86 g/L, while for GLD in wastewater, it was between 8.11 and 17.81 g/L. These results indicate that the presence of wastewater can enhance CO2 absorption. Physicochemical analysis confirmed the presence of CaCO3 after the reaction.The capture of CO2 by side streams in alkaline wastewater is a promising method for reducing CO2 and valorizing these byproducts.","PeriodicalId":100015,"journal":{"name":"ACS Sustainable Resource Management","volume":"2 1","pages":"119–126 119–126"},"PeriodicalIF":0.0,"publicationDate":"2024-12-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.acs.org/doi/epdf/10.1021/acssusresmgt.4c00373","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143084910","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}

TWMCC/PVA composite films were prepared using the solution casting method, and the fabricated films were characterized using various analytical techniques for determining chemical, morphological, thermal, mechanical, water resistance, and UV-barrier properties. Strong hydrogen bonding between the hydroxyl groups of PVA and TWMCC forms a dense network structure, resulting in improvement of water resistance, water vapor barrier, UV-blocking properties, and thermal properties, of the films. 5 wt % TWMCC increased the water contact angle of PVA film to 81.54°, while pure PVA film had a lower contact angle of 29.31°. The incorporation of 3 wt % TWMCC increased the tensile strength of PVA film by about 2-fold (from 9.11 ± 1.15 to 18.5 ± 1.93 MPa). PVA composite film containing 5 wt b % TWMCC showed promising performance in extending fruit shelf life by preserving grapes for up to 18 days, while unpacked grapes lost marketability within one week. The findings of the study reveal that microcrystalline cellulose derived from tea industry waste can be used as a suitable filler material for the development of environmentally friendly and sustainable food packaging to minimize the global plastic pollution issue.","PeriodicalId":100015,"journal":{"name":"ACS Sustainable Resource Management","volume":"1 12","pages":"2518–2529 2518–2529"},"PeriodicalIF":0.0,"publicationDate":"2024-12-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143125908","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}

In this article, a novel sorbent material (MOF-DHB) has been dove-tailed by a post-synthetic modification technique (here, 1,2-dihydroxybenzene functionalized on the surface of UiO66-NH2), and sorption efficacy of the material for UO22+ and Th4+ from acidic solutions has been explored for the first time. It exhibits very high (>98%) removal efficiency for both actinides compared to the unfunctionalized MOF (with 52% and 65% for UO22+ and Th4+, respectively). The surface functionalization induced the enhancement in the saturation sorption capacity values of UO22+ and Th4+ (nearly 1.3-fold compared to parent MOF). Reusability has been demonstrated by quantitative back extraction of metal ions using suitable stripping agents and subsequent use of the sorbent for new extraction without any performance compromise. The synthesized MOF is stable up to 500 kGy dose and can be applied for more than five cycles of operation. FTIR analysis illustrates that major modes of coordination in MOFDHB and MOF are through phenolic −OH and −NH2 groups.","PeriodicalId":100015,"journal":{"name":"ACS Sustainable Resource Management","volume":"1 12","pages":"2530–2538 2530–2538"},"PeriodicalIF":0.0,"publicationDate":"2024-12-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143127138","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}

This study employed the development of a plasma surface-engineered activated carbon fiber (ACF) mat to remove a model heavy metal (HM) manganese (Mn) from the air efficiently. This eco-conscious initiative will help to improve the air quality in severely contaminated mining regions. We investigated various precursors for plasma surface modification. The ACF treated with 2-mercaptoethanol (MCE) plasma exhibited superior filtration efficiency for HM-contaminated aerosols, resulting in a 25% enhancement compared to that of the pristine ACF. A comprehensive analysis of the mat’s physicochemical properties was conducted after modifications and filtration. The pressure drop values between the pristine and plasma-treated ACFs were found to be insignificant. Ultimately, these results have demonstrated the potential of MCE plasma-treated ACF as an efficient filter for removing HMs from the air.","PeriodicalId":100015,"journal":{"name":"ACS Sustainable Resource Management","volume":"1 12","pages":"2602–2611 2602–2611"},"PeriodicalIF":0.0,"publicationDate":"2024-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143127448","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}

This work focuses on the development of a biocoating from WCO for paper-based packaging with improved hydrophobicity and moisture barrier properties. WCO was epoxidized and acrylated to form AWCO, subsequently characterized, and modified into a water-based emulsion using a poly(vinyl alcohol) solution. (Aminopropyl)triethoxysilane was grafted in varying proportions to AWCO emulsion to enable cross-linking onto hydroxyl groups of cellulosic paper. The curing process of the coated paper (∼40 gsm coating) was carried out at 130 °C for 5–7 min to ensure complete cross-linking. The coated papers exhibited a water contact angle of greater than 90°, a kit rating of 12/12 along with excellent water retention and oil and ice repellency. Water vapor transmission rate reduction up to ∼129 g/m2·day was achieved by depicting the moisture barrier as well. High glass transition temperatures (Tg) and thermal stabilities of the coatings revealed their suitability for hot food packaging. The coatings most importantly depicted high repulping potential and home compostability, making it a commercially feasible replacement for the existing plastic liners in paper packaging.","PeriodicalId":100015,"journal":{"name":"ACS Sustainable Resource Management","volume":"1 12","pages":"2612–2620 2612–2620"},"PeriodicalIF":0.0,"publicationDate":"2024-11-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143127473","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}

The work analyzes in detail three methods for recovering lanthanum from leaching solutions of spent catalytic cracking catalysts. Selective precipitation with ammonia solution in the pH ranges of 3.2–6.8 and 6.8–8.2 made it possible to partially separate aluminum and obtain products with a La2O3 content of 50.9–51.7 wt %. The sediments contain basic lanthanum salts and their hydrates, complex lanthanum and aluminum salts, and lanthanum and aluminum hydroxides. The La2O3 content in the precipitation product with a saturated solution of sodium bicarbonate in the pH range of 4.5–4.7 was 17.6–18.3 wt %. The precipitate is a mixture of hydrated lanthanum carbonate and aluminum hydroxide. As an alternative method for recovering lanthanum compounds, evaporation of a nitric acid leaching solution was considered. Evaporation does not require additional reagents and allows one to obtain a solution of nitric acid at a concentration of 10.8 M for reuse. The residue after evaporation contains at least 80.0 wt % of the liquid phase and after cooling to 30–35 °C is a mixture of hydrated aluminum and lanthanum nitrates. The lanthanum content in the solid residue after evaporation and heat treatment reaches 19.6–20.2 wt %.Recycling rare earth elements like lanthanum from spent catalysts reduces resource depletion and minimizes waste. This research optimizes environmentally sustainable recovery methods to enhance circular economy practices in industrial applications.","PeriodicalId":100015,"journal":{"name":"ACS Sustainable Resource Management","volume":"1 12","pages":"2593–2601 2593–2601"},"PeriodicalIF":0.0,"publicationDate":"2024-11-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.acs.org/doi/epdf/10.1021/acssusresmgt.4c00364","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143127577","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}
