From Lab to Market: 

Greenore continues turning billions of tons of solid wastes and carbon emissions into unconventional resources.

Dr. Sean Zhou, was one of the first cohort of Columbia Engineering Translational Fellows in 2015. He launched Greenore, with his PhD advisor, Dr. Alissa Park, with the support of Columbia Technology Ventures (CTV) in the summer of 2016.

Greenore provides disruptive solutions of reducing and reusing both solid wastes and carbon emissions for industrial sectors. In particular, Greenore converts iron and steel making by-product, slag, into valuable chemical products (calcium/magnesium carbonate, iron oxide, silica, alumina and rare earth concentrate) while consuming CO2 as a reactant. Greenore provides technical services through the full life cycle of its technology associated with licensing as well as quickly expands its global capacities via design, build, own and operate satellite plants.
