Optimizing CO2 sequestration in industrial waste.

Front Page

At the CarbMin Lab, we develop practical carbon capture, utilization, and storage strategies through cutting edge research and collaboration and partnership with industry. Our research focuses on carbon mineralization, a process using mine waste that takes CO2 from emissions and the atmosphere and converts it into rock.

Technology for a changing climate

Greenhouse gases such as CO2 trap heat, causing global temperatures to rise. In order to avoid the most disastrous climate predictions, we need to limit this warming to 1.5 °C above pre-industrial levels, according to the International Panel on Climate Change (IPCC). This means not only cutting greenhouse gas emissions to net zero, but also removing billions of tons of CO2 from the atmosphere. Once removed, these gases will need to be stored in long-term, safe environments.

At the CarbMin Lab, we harness existing mining processes to trap and safely store CO2. The capacity of some mines’ waste rock to store CO2 through carbon mineralization may exceed an individual mine’s greenhouse gas emissions tenfold. Furthermore, the end product is an environmentally benign carbonate rock which produces other benefits such as tailings stabilization, dust reduction, and toxic metal encapsulation. Within the CarbMin research program, we investigate and accelerate natural carbon mineralization processes, develop technology to enhance CO2 uptake at mine sites, and quantify carbon mineralization potential both regionally and at an individual mine scale.
