Engineering Biochar‐Derived Functional Materials for High‐Performance Supercapacitors: Design Principles, Mechanisms, and Scalable Strategies

Carbon Energy, EarlyView.
ABSTRACT Biochar has emerged as a useful and adaptable source of carbon for supercapacitor electrodes. Its value comes from the way biomass chemistry, thermal conversion, and activation conditions shape the resulting pore network, surface groups, and degree of carbon ordering.

Bioplastic polyhydroxyalkanoate conversion in waste activated sludge

Journal of Environmental Management
Polyhydroxyalkanoates (PHA) have been proposed as a promising solution for plastic pollution due to their biodegradability and diverse applications. To promote PHA as a competitive commercial product, an attractive alternative is to produce and recover PHA in the use of mixed cultures such as waste activated sludge from wastewater treatment plants. PHA
