Electrochemical Systems to Enable Circularity
Abstract: Electrochemical technologies are emerging as key enablers of circular chemical systems as electrochemical systems are modular and able to connect to stranded energy sources. In this context, I will highlight recent advances in electrochemical processes that address carbon capture and utilization, resource recovery from waste, and sustainable fertilizer production. Specifically, I will provide insights into how bipolar membrane (BPM) electrolysis could provide a promising avenue to integrate carbon capture systems with conversion systems. Second, I will examine how electrified separations processes may enable more effective nutrient management at agricultural and water treatment sites. Finally, I will discuss the prospects for fully decentralized fertilizer production and highlight the potential advantages and disadvantages of distributed chemical manufacturing.
