Biochar starts as biomass - plant matter, old wood, agricultural waste - that is pyrolyzed, or heated to high temperatures without oxygen. The result is a solid chunk of carbon that can no longer decay and release CO₂ back into the atmosphere. Biochar is an example of a CDR method that comes with an end product that can be used for many things, including as a soil amendment. Our biochar removals are supplied by Pacific Biochar.
Bio-oil also starts off as biomass and undergoes fast pyrolysis. This results in something similar to crude oil, but with less viability as a fuel. Since it has a density similar to crude oil, it can be injected into wells left empty by the oil and gas industry without risk of leaking back out into the atmosphere. It’s basically a way of putting oil back where it came from. Our bio-oil removals are supplied by Charm Industrial.
Weathering refers to the natural process whereby CO₂ comes into contact with water and alkaline minerals. The chemical reactions that then take place result in stable carbonate minerals that essentially trap the carbon. The enhanced part means that humans step in to make this happen on a faster time scale, and it’s important to note that trapping carbon in carbonate minerals is one of the safest ways we can store the excess CO₂ in the atmosphere. One approach uses the very abundant, naturally reactive mineral olivine, grinding it and letting it react with water. Our mineralisation removals are supplied by greenSand.
Everyone loves planting trees, and so do we! Reforestation means planting trees where they used to be and turning once forested land back to how humans originally found it. Trees process CO₂ through photosynthesis, and store carbon in their trunks and roots, as well as draw carbon into soils. Trees are another win-win climate solution and provide many co-benefits, including ecosystem health and, of course, homes for lots of cute animals. Our forest removals are supplied by Forestry Partners.
Soils can hold more carbon than the atmosphere, and healthy soils are full of carbon. Regenerative agricultural practices, such as no-till or cover crops, restore carbon-depleted soils and improve fertility. Soil carbon sequestration is a great example of how low cost, simple changes can have a big impact on the climate, as well as improve agricultural ecosystems and the sustainability of our food supply.
