The planet’s air conditioner is the process of weathering of rocks like wollastonite that have removed carbon dioxide and cooled the planet for billions of years. There is no big machine, it is a simple reaction and luckily when you spread crushed wollastonite you can speed it up.
Fresh off the press, this study makes the case that microbes play an important role in accelerated weathering reactions, the same reactions that are spurred on when wollastonite is spread on the soil. Accelerated weathering is the breakdown of the silicate minerals in the soil creating carbonates, calcium carbonate in the case of wollastonite. Calcium […]
Large-scale field trials of rock dust applications in agriculture are precisely what we need to harness the benefits of applying crushed calcium and magnesium silicates to agricultural fields. This summary reports on the early findings of a study currently in progress. The benefits of applying rock dust to agricultural fields are wide-ranging and economically affordable […]
Climate change has been on the international stage for a while now. Remember the Tokyo Protocol? Many governments signed it into effect the same year this study was published. As one of the first, this study proposes using rocks as a solution to reduce atmospheric levels of CO2 rapidly. After twenty-plus years, turning carbon into […]
In this month’s issue of Environmental Science & Technology three researchers we work closely with at Guelph University, Ontario published an article making the case for carbon sequestration by using wollastonite in rooftop soils everywhere. If all the available urban roof space around the world contained plants and soils with wollastonite, 1% of global carbon […]
