The ultimate goal of this partnership is zero-waste via the comprehensive utilization of iron and steel slags with added potential benefits of: reducing the land for the stockpile or landfill of the iron and steel slags; reducing the carbon emission of the iron and steel industries; converting the waste into valuable feedstocks and products for several other cross-industries; and maximizing the overall sustainability of the iron and steel industry in terms of the environmental and economic impacts.
In October 2016, a lab demonstration unit to repurpose iron and steel slag was commissioned at Columbia University with a target annual capacity of 10 metric ton slag per year.
In December 2016, Baotou Steel delegates visited Columbia University to observe the operation of the demo unit and to assess generated products. Baotou Steel and Columbia teams also discussed the plan for the next pilot scale project to be performed at Baotou Steel in China.
On May 25, 2017 at the Columbia Global Center in Beijing, a media adviA Joint Venture between GreenOre CleanTech LLC and Baotou Steel Group has been established. The USG assistance facilitated the smooth establishment of the JV and business operation with Chinese state-owned companysory was conducted for major US and Chinese news outlets (Bloomberg, AP, Wall Street Journal, People’s Daily, etc.) to advance the EcoPartnership between Columbia Engineering and China’s Baotou Iron and Steel (Group) Co.

Baotou Steel (Group) and GreenOre CleanTech Co., Ltd., a Columbia University spin-off startup founded in 2016, officially registered as a joint venture at the Chinese local Department of Commerce in January 2018, with the pilot plant funding fully available.
The joint-venture team formed by core members from both Baotou Steel and Columbia University is designing and constructing the pilot plant with a main reactor of 10 cubic meters. The pilot plant is on-track to be completed by January 2019.
The EcoPatnership has mobilized $270,000 USD from Korean Energy Technology Evaluation and Planning (KETEP), Mission Innovation 2019-2021 to continue to develop and demonstrate the technology.
By April 2020, Baotou Steel and Greenore Cleantech LLC demonstrated the technology, with a capacity of 680-6,800 metric tonne slag/y carbonation. The technology demo validated the potential economic feasibility of further technology scale-up to the commercialization level.
