Greenore Cleantech

Greenore Cleantech: Greenore Cleantech is a start-up from Columbia Engineering based on unconventional resource utilization research from the lab of Columbia Professor Dr. Ah-Hyung (Alissa) Park. Dr. Park is joined by Dr. Xiaozhou Sean Zhou (Co-founder, Co-inventor and CEO). Greenore Cleantech's technology converts iron and steel making by-product (slag) into valuable chemical products (calcium carbonate, iron oxide, silica, alumina and possibly rare earth concentrate depending on the feed) while consuming CO2 as a reactant. The company focuses on providing technical services through the full life cycle of its technology and has also established a joint-venture with China Baotou Steel (Group) in November 2017. A pilot plant with $5M capex has been commissioned this spring, which is also the 1st industrial prototype of its kind in the world. A scale-up commercial plant with total investment estimate of $50M with 90% committed from Boutou Steel will be launched Q4 2019. Greenore Cleantech won the Mission Innovation grant from the South Korean government in November 2018. A joint demonstration project with Japan Coal Energy Center, Wyoming Infrastructure Authority and Columbia Engineering will also be announced during the 2019 G20 Osaka Summit in late June.
