We are proud to announce that our company Konsiteo Limited and Milk Paint Boutique, participate in the removal of CO2 from the atmosphere. New technologies: Climeworks, CarbonCure, Project Vesta and Charm Industrial.
While methane is 28-times more heat-trapping than carbon dioxide, methane’s lifespan is just a decade, while CO2 — known as a long-life pollutant — remains in the atmosphere for 1000 years. After ten years, methane is broken down in a process called hydroxyl oxidation into CO2, entering a carbon cycle which sees the gas absorbed by plants, converted into cellulose, and eaten by livestock.
To put that into context, each year 558m tons of methane is produced globally, with 188m tons coming from agriculture. Almost that entire quantity — 548m tons — is broken down through oxidation and absorbed by plants and soils as part of the sink effect. That means that provided no new animals are added to the system, then the same amount of carbon dioxide produced by livestock is actually used by plants during photosynthesis.
“That’s not to say livestock has no impact on climate, but we are not adding additional warming,” Prof Mitloehner says. The average ruminant produces 250-500 litres of methane a day. Globally, livestock are responsible for burping (and a small amount from farting) the methane equivalent of 3.1 gigatonnes of carbon dioxide into the atmosphere annually.
Climeworks uses renewable geothermal energy and waste heat to capture CO2 directly from the air, concentrate it, and permanently sequester it underground in basaltic rock formations with Carbfix. While it’s early in scaling, it’s permanent, easy to measure, and the capacity of this approach is theoretically nearly limitless.
CarbonCure injects CO2 into fresh concrete, where it mineralizes and is permanently stored while improving the concrete’s compressive strength. Today they source waste CO2 but represent a promising platform technology for permanent CO2 storage, a key component of future carbon removal systems.
Project Vesta captures CO2 by using an abundant, naturally occurring mineral called olivine. Ocean waves grind down the olivine, increasing its surface area. As the olivine breaks down, it captures atmospheric CO2 from within the ocean and stabilizes it as limestone on the seafloor.
Charm Industrial has created a novel process for preparing and injecting bio-oil into geologic storage. Bio-oil is produced from biomass and maintains much of the carbon that was captured naturally by the plants. By injecting it into secure geologic storage, they’re making the carbon storage permanent.
