Ruichi Zhang

I completed my PhD in 2022 from University of Oulu (Finland). The topic of my thesis was vanadium removal and recovery from liquid waste streams. I mainly focused on the synthesis of bio-based sorbents used for wastewater treatment and valuable metal recovery from the polluted water. I joined Bio and Circular Economy research group (Tampere University) as a post-doctoral researcher in September 2022. The goal of my current research is to eliminate the emerging pollutants from sewage sludge during hydrothermal carbonization process.
