Rousseva's research focuses on bulk, trace, and rare-earth element removal and recovery using Eutectic Freeze Crystallization (EFC). EFC's efficiency and complete resource recovery potential fit into the circular economy framework, and one of its most important applications is urban mining. Namely, the high quantities of bulk and precious metals found in e-waste (such as batteries, magnets, PCBs, etc.) can be recovered with EFC instead of discarded or inefficiently recycled.
