Dr Song Zhou

Research Scientist, ENERGY

  • Dr Song Zhou’s research focuses on CO2 mineralisation, i.e. the integration of CO2 capture, utilization and conversion with solid waste valorisation processing, such as coal fly ash, chloride waste and municipal solid waste (MSW) incineration ash. Apart from intensive lab researches, Dr Zhou has rich experience in industrial project management and execution, and strong leadership. He has been maintaining connections with industrial partners, such as SUEZ, Latrobe Magnesium, EPA Victoria, and mineral companies overseas.
  • Dr Zhou’s research has made significant contributions to the valorisation processing of Victorian Brown coal fly ash, otherwise an overwhelming amount of alkaline solid waste of significant environmental issues, via proposing, validating and confirming a whole flowsheet to obtain highly value-added metals of Mg and Fe. In the meanwhile, the wastes, including CO2 and chloride leachates can be efficiently and effectively utilized and recycled to form a circular-economy. This led to successful fund-raising for his industrial partner, a pilot plant that is being built in Latrobe Valley, and a patent under application. Dr Zhou is also dedicated to flowsheeting, techno-economic analysis (TEA), which is critical for the implementation of any new industrial processes, using Aspen software and CSIRO-developed technologies.
