Summary: Experiments investigated the leaching behavior of Zn from end-of-life tire rubber. The analysis revealed that ZnO was the main Zn-containing phase in the material. Both exposed and encapsulated ZnO particles were found through SEM-EDS analysis. Acid leaching tests showed that carbon black in the material could be oxidized and dissolved by HNO3, resulting in the dissolution of completely encapsulated ZnO particles. Leaching tests using HNO3 as the lixiviant demonstrated that over 98% of Zn could be recovered under specific conditions.

Summary: This study introduced a stepwise downsizing method of gel particles in reclaimed rubber to a micro-nano scale, leading to improved dynamic performance in tire sidewall. The addition of reclaimed rubber with low Mooney viscosity effectively enhanced the dynamic mechanical properties of the rubber blends, including wet resistance and rolling resistance, while also significantly increasing flexing fatigue resistance compared to traditional tire sidewalls.

Summary: A novel silica reinforced epoxidized SSBR/epoxidized BR nanocomposite (S-ESSBR/EBR) without using silane coupling agent (SCA) was prepared in this study. ESSBR and EBR with different epoxidation degree were synthesized using oxidant H2O2 and reaction-controlled phase-transfer catalyst CPC-PW4O16. The distribution of silica in two phases became homogeneous by transferring silica nanoparticles from ESSBR phase to EBR phase with increasing epoxidation degree of EBR. The S-ESSBR/EBR nanocomposite showed high wet skid resistance, low rolling resistance, and excellent abrasion resistance as green tire tread.

Summary: The hybridization of microscale and nanoscale tire rubber with SBS modified asphalt binder (SMB) was found to stabilize the molecular weight distribution and decrease oxidative condensation reaction during weathering. The hybrid modified asphalt exhibited improved crack resistance at low temperature and deformation resistance at high temperature, leading to enhanced natural weathering resistance of SMB.

Summary: Rapid economic growth has led to increased waste generation in multiple industries, including the automotive sector, due to the lack of established recycling and utilization methods. One particular concern is the large amount of post-consumer tires, which are considered burdensome waste due to the emission of volatile organic compounds (VOCs). To address this issue, novel and environmentally friendly methods for utilizing these tires are needed. One promising approach is shredding the tires to generate ground tire rubber (GTR), which can be used as filler in polymeric materials. This study focuses on the thermomechanical treatment of GTR with zinc borate in a twin-screw extruder to improve its performance in flexible polyurethane (PU) foams. The impact of modification parameters on various properties, including cellular structure, mechanical performance, thermal stability, thermal insulation, and acoustic properties, was investigated. VOC emissions from the fillers and composites were also monitored and evaluated. The results showed that the proposed method of GTR thermomechanical treatment with zinc borate particles can enhance the performance of flexible PU foamed composites and reduce VOC emissions, thus expanding the application range of GTR and providing new ways for its efficient utilization.

Summary: A new strategy is proposed to improve the distribution of silica in rubber blend without using a silane coupling agent. Silica-filled epoxidized SSBR/ENR nanocomposites have better interfacial interaction and improved dispersion of silica compared to silica-filled SSBR/NR nanocomposites with Si75 as the coupling agent. The epoxy groups effectively adjust the phase selective distribution of silica. The S-ESSBR12/ENR18 nanocomposite shows the best performance, increasing wet-skid resistance by 118%, reinforcing index by 38%, abrasion resistance by 40%, and decreasing rolling resistance by 23%. These ecofriendly nanocomposites have potential application in green tire tread production.

Summary: This study investigates the effects of zero discharge of nutrient solutions on cucumber growth, leaf photosynthesis, and yield and quality under greenhouse conditions. The results show that the zero discharge treatment has minimal impact on most measurement indicators, and cucumber plants can adapt to the treatment over time. Leaf mineral element contents show variations on some treatment days, but cucumber yield and fruit quality remain stable throughout the experiment.
