Disappointingly, oxidation always enriches high polarity poor-capacitance O-C=O groups (i.e., carboxyl/lactone) on the carbon material surface, which act as a double-edged sword for biochar's application in organic pollutant adsorption and electrochemical energy storage. Herein, microwave-induced air oxidation shock (MW-AOS) is proposed as a rapid and simple strategy to selectively oxygenate the surface of activated biochar (AB). Characterization results show that the surface of the pristine AB is remarkably oxygenated from 3.8 % to 11.8 % after MW-AOS at an output power of 800 W for 15 s. Interestingly, surface oxygenation is achieved while reducing the high-polarity poor-pseudocapacitance O-C=O groups (i.e., carboxyl/lactone) is selectively achieved at a shorter irradiation time (15 s). Batch adsorption results indicate that MW-AOS remarkably increases the adsorption of various organic pollutants (dyes and antibiotics) by AB. Electrochemical analysis reveals that the specific capacitance of the AB is improved by 250 % (from 60 to 208 F/g at 1 A/g after AOS at 800 W for 15 s), attributed to reduced electrical resistance and enhanced ion transport. Finally, this study could pave a new route for the surface engineering of AB for these applications.</div></div>","PeriodicalId":22097,"journal":{"name":"Sustainable Materials and Technologies","volume":"44 ","pages":"Article e01375"},"PeriodicalIF":8.6,"publicationDate":"2025-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143735257","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study focuses on developing novel stainless steel welding electrodes using a flux-modified mild steel core wire. The primary objective is to achieve stainless steel-like mechanical properties while minimizing the release of hazardous emissions such as hexavalent chromium, ozone, and ultraviolet radiation. These newly developed electrodes are designed to provide the strength and corrosion resistance of stainless steel grades 304 and 316 without requiring modifications to conventional manufacturing processes, making them highly suitable for industrial applications, including structural fabrication, automotive components, and marine engineering. A novel flux composition incorporating nano-sized calcium carbonate and calcium titanate was formulated to enhance arc stability, reduce spatter, and improve alloying efficiency. Mechanical testing demonstrated significant improvements in tensile properties, with the ultimate tensile strength increasing to 544 MPa for the stainless steel 304 electrode and 560 MPa for the stainless steel 316 electrode. The yield tensile strength increased to 230 MPa and 285 MPa, respectively, reflecting enhanced resistance to deformation. Bending strength improved to approximately 460 MPa for the stainless steel 304 electrode and 490 MPa for the stainless steel 316 electrode, while microhardness values increased to 240 Vickers hardness number (VHN) and 250 VHN, respectively. Microstructural analysis revealed a refined weld structure with increased acicular ferrite content, leading to enhanced weld integrity and strength. In addition, the optimized flux formulation effectively reduced the release of toxic emissions, with hexavalent chromium concentrations decreasing by 32.7 % for stainless steel 304 electrodes and 22.7 % for stainless steel 316 electrodes. These results demonstrate that the newly developed electrodes provide a balanced combination of mechanical performance and environmental sustainability. The novel approach not only enhances the efficiency of stainless steel welding but also significantly reduces health risks for welders. The findings contribute to the advancement of cleaner welding technologies, offering a cost-effective and sustainable alternative for various industrial applications.</div></div>","PeriodicalId":22097,"journal":{"name":"Sustainable Materials and Technologies","volume":"44 ","pages":"Article e01372"},"PeriodicalIF":8.6,"publicationDate":"2025-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143726276","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper aims to review the diverse technologies related to the recycling and revalorization of single-use food packaging materials based on PLA and PHAs (e.g. chemical depolymerization, solvolysis, mechanical recycling (mechanochemistry), enzymatic hydrolysis, fermentation, gasification and hybrid approaches), as well as to address an important issue for plastic materials manufacturers as is the reprocessing of residual materials obtained during the manufacturing of food packaging. The latter is aimed at reducing waste and increasing the economic sustainability of the materials and the business. Mechanical recycling (mechanochemistry) is recommendable with the aim of reducing waste and increasing the sustainability of residual materials obtained during the manufacturing of industrialized biodegradable food packaging based on PLA and PHA. In contrast, chemical (chemical depolymerization and solvolysis), enzymatic and fermentation recycling is recommendable to treat discarded single-use food packaging materials made from PLA or PHA, thus yielding chemical precursors (monomers) and fuels, which can then be used as feedstocks to produce their corresponding recycled/renewed polymers or copolymers, thereby diminishing the need for new chemicals. Finally, the gasification process is currently representing an interesting perspective for connecting hybrid recycling approaches between the use of chemistry and bioprocesses, and not merely obtaining synthesis gas as a precursor of monomers, copolymers and/or recycled/renewed biodegradable polymers.</div></div>","PeriodicalId":22097,"journal":{"name":"Sustainable Materials and Technologies","volume":"44 ","pages":"Article e01364"},"PeriodicalIF":8.6,"publicationDate":"2025-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143681044","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
