Here, we report a two-component biobased adhesive system consisting of epoxidized biobased oils and biobased acids, with five biobased options available for each component category. Our strategy employs a method where two components are blended and melted to form a homogeneous mixture and, then, chemically cross-linked to form a covalent network upon heating. This approach has achieved high adhesive strength under dry and wet conditions for single-lap-joint bonded specimens. The materials tested include aluminum, copper, steel, brass, and molybdenum. Specifically, the lap shear strength of aluminum (1060) joints achieved a result of 6.2 ± 0.8 MPa under dry conditions and 4.4 ± 0.6 MPa under wet conditions.</p><p >This study presents a two-component biobased adhesive system for metal bonding, formulated from epoxidized soybean oil and organic acids.

At present, the Fund plays a key role in China, but with a budget deficit of up to 3 billion Yuan per year. By linking the achievements of WEEE recycling to the policy to promote carbon neutrality, the Fund would compensate for the associated fee, thereby facilitating sustainable recycling. To test the feasibility of this strategy, we have assessed GHG emission reduction levels associated with WEEE recycling based on archival data analysis and field research. The results show that the GHG reduction related to WEEE recycling in Sichuan Province is 160,279.152 tCO<sub>2eq</sub>. and 8.36 million tCO<sub>2eq</sub> in China in 2021. But this amount significantly underestimates the potential benefits due to methodology limitations. It is assumed a reformed approach that can increase the estimated GHG reductions by 42% (to 11.85 million tCO<sub>2eq</sub>). This reform highlights the key role of including downstream resource recovery processes in carbon trading schemes, which is expected to alleviate the current deficit. The study suggests that the GHG emission reduction assessment of WEEE recycling should be re-formed to promote the sustainability of WEEE recycling.</p>","PeriodicalId":100015,"journal":{"name":"ACS Sustainable Resource Management","volume":"2 5","pages":"766–774 766–774"},"PeriodicalIF":0.0,"publicationDate":"2025-04-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144104888","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}
