Unlocking the Potential of Electrolyte Recovery from Battery Waste: A Promising Path to Sustainable and Safe Li‐Ion Batteries

open access: yesBatteries &Supercaps, EarlyView.
Due to several challenges, electrolyte recovery from spent battery waste has been less explored compared to electrode materials. This study presents various strategies for recovering electrolytes from spent battery waste. Electrolyte recovery can prevent hazardous chemicals from being released into the environment.

Thermal degradation of impact‐modified PMMA in mechanical and chemical recycling

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Abstract Poly (methyl methacrylate) (PMMA) is a thermoplastic with outstanding tensile strength, UV resistance, and a high level of transparency that has been used widely for optical applications such as glazing in the automobile industry. Mechanical recycling, the most widespread method, degrades the physical properties and prevents reusing PMMA in ...
