Trapping “sky carbon” in the soil for climate impact and agronomic benefit
CO2, made up of carbon and oxygen, is absorbed from the atmosphere and then used by plants during photosynthesis to build their leaves, stalks, or fruits. Much of this plant matter becomes green waste, which is commonly burned or mulched, returning that CO2 to the atmosphere. However, if it is disposed of via a process called gasification (high heat with little oxygen), we can trap some of that the carbon as biochar byproduct and put it in the soil. In this way, we can drawdown 50% of that CO2 while also producing renewable electricity and offsetting the emissions that would have resulted from fossil fuel generation. This SkyCarbon biochar’s precious carbon also stimulates root and plant growth, thus actively sequestering more CO2 over time. We are currently organizing projects worldwide which match fundraising with biochar production and composting activities that allow everyone to become involved in carbon drawdown at domestic, community, and global scales.
Trapping the carbon
The top 1 meter of soil contains an estimated 1417 gigatonnes (GtC) of Soil Organic Carbon, which is nearly twice the quantity of atmospheric carbon (847 GtC as carbon dioxide – CO2) Professor Rattan Lal, soil scientist at Ohio State University says, “a mere 2% increase in the carbon content of the planet’s soils could offset 100% of all greenhouse gas emissions going into the atmosphere.”
local char for your compost pile
Our high-temperature biochar is low-tar and conductive, which means that it boosts the electron exchange of the microorganisms in your compost pile, allowing you to achieve better temperatures and a faster composting process. This electron-exchange-boosting capacity is specific only to high-temperature biochar like ours and continues in the soil via increased cation-exchange capacity, resulting in higher plant growth rate.
Biochar is Fabulous!
The Local Carbon Network creates community-based carbon sequestration. We have structured our networks similarly to the way the Local Food Movement, Farmers’ Markets or Community Supported Agriculture have been organized. We use community organizing techniques to bring together drawdown volunteers, operating at home or at community gardens, with green-waste streams that would otherwise go into landfills, all supported by conscientious, drawdown-committed sponsors. This enables a realistic, practical, and effective method of mitigating climate change while regenerating the earth’s fragile and depleted soils.
If business-as-usual carries on at its current pace, the earth will reach its CO2 limit in just 15 years, meaning our soils may only yield 60 more harvests. But we can act effectively now to support and optimize regenerative agriculture methods by sponsoring the distribution and incorporation of the sky carbon in biochar into the soils on which our lives are so dependent.
Scaling the idea.
At a global level, we fall under the PyCCS (Pyrogenic Carbon Capture and sequestration) or the BECCS (Bioenergy with Carbon Capture and Storage) category of technologies. Our global goal is to establish hundreds of LCNs over the next 50 years, sequestering thousands of tonnes of CO2e.
LCN has sequestered:
Kilograms CO2e to date
1 tonne of gasified and co-composted biomass sequesters/offsets 5272kg of CO2 equivalent and emits 1650kg of renewable CO2 – there is a net sequestration of 3622kg of CO2 equivalent per ton of biomass used, plus the nitrous oxide and methane emission reduction which bring it to 4000kg/ton of biomass – if we divide this number by 1 000 we see that 1kg of biomass sequesters 40kg of CO2 equivalent. We have conservatively halved the numbers on the co-composting multiplier and prefer to say that 1kg of biochar (not biomass) has a maximum carbon impact of 40kg of CO2e.
You can become a drawdown volunteer and receive a discounted or free compost tumbler and biochar supply, you can buy SkyCarbon biochar and support sponsored projects or you can sponsor a project directly and get visibility and recognition on our website.
Whether it is time or money you can offer, they are both really appreciated!
