What are the latest developments in non-destructive battery recycling techniques?5 answersRecent developments in non-destructive battery recycling techniques include the use of low-temperature (electro)hydrometallurgical processes for lead-acid battery recycling. These processes involve modified electrolytes, improved reaction engineering, better reactor design, and control of operating conditions. Another development is the dissolution and electrochemical deposition of transition metal oxides in the same solvent for sustainable battery material usage and recovery for Li-ion battery cathodes. This technique allows for the formation of high-performing cathodes from "end-of-life" batteries, contributing to more sustainable battery production. Additionally, European companies are planning major expansions to battery recycling capacity, with Umicore aiming to build the world's largest battery recycling facility capable of processing 150,000 metric tons per year of battery materials. These advancements in non-destructive battery recycling techniques are crucial for addressing the increasing demand for battery materials and promoting environmental sustainability.
What are the latest developments in green polycabonate?5 answersThe latest developments in green polycarbonate involve the use of renewable resources as starting materials, green catalysts, and green solvents. Biobased renewable resources such as lactic acid and itaconic anhydride are used as starting materials. Enzymes like lipase and protease are used as green catalysts. Green solvents such as water, supercritical carbon dioxide, and ionic liquids are utilized, with water being commonly used for emulsion systems. These developments have led to the production of bioplastics with a high biomass content, which are applicable for coatings. Additionally, the mechanism of catalysis of enzymes in the oligomerization of lactic acid alkyl esters has been examined, providing insights into the enantioselection process. The use of green technology in the production of green composites has also resulted in cost-effective materials with reduced electricity and water consumption, as well as decreased CO2 emissions and solid waste generation.
