How it works ?
From air to rocks, while removing health hazards from asbestos residues
We propose an integrated capture and sequestration system comprising a novel modular direct-air capture device whose high-concentration gaseous CO2 output is used for the on-site carbonation of minewaste. Our systems can be directly installed at mine waste sites, thereby eliminating the need to transport CO2 or mineral feedstock over long distances. We plan to first install our systems at abandoned asbestos mine sites in the province of Quebec in Canada, where 2 Gt of existing mine tailings offer a CO2 sequestration potential of about 700 MtCO2, and where the process will be powered by the 100% renewable Hydro-Quebec grid.
First, we draw CO2 directly from the atmosphere
Our DAC device uses a continuous adsorption/regeneration process with monolith sorbent reactors, based on a proprietary sorbent functionalized with an amine polymer, resulting in an inexpensive high specific area material capable of fixing and releasing CO2 molecules in a highly energy-efficient process.
Then, we store it for millions of years
We use a simple low-temperature process where metals, such as magnesium present in chrysotile serpentine (asbestos), react with dissolved CO2 in an aqueous solution to form a stable carbonate compound.
