Rocks
Enhanced weathering of rocks could speed up carbon capture and help tackle climate change. When dissolved CO2 in rain falls on basalt rock, the chemical reaction creates a carbonate mineral that effectively sequesters carbon indefinitely. The problem is that, in nature, this is a very slow and location-dependent process. But The Future Forest Company is starting an experiment that will crush basalt rocks and spread them in a forest on the Scottish Isle of Mull. By increasing the area of exposed basalt, the weathering process is accelerated, while the remineralised soil could boost forest growth by up to 40%.
