Built on Nature’s carbon cycle, SkyClean is a universally applicable carbon capture system available to the agriculture and forestry sectors. As a technology it can be deployed in all locations where organic feedstock is available, even supporting high-intensity sustainable agriculture in the process.
The core of SkyClean is a pyrolysis process in which organic waste from agriculture and forestry is converted into biochar, gas, and oil by heating to a high temperature without the presence of oxygen.
In the pyrolysis process, half of the carbon in the waste is converted to biochar, while the other half becomes oil and gas. Biochar is a stable material that only decomposes very slowly, and in SkyClean’s carbon cycle, the half of the carbon that turns into biochar is effectively removed from the atmosphere, thus providing a very substantial carbon offset.
The normal plant waste carbon cycle vs. SkyCleans’s plant waste cycle:
By storing half of the carbon in agricultural waste as biochar in each cycle, SkyClean achieves the paradoxical but very beneficial effect that the more fuel the plant produces, the more CO2 is removed from the atmosphere.
Biochar has multible benefits besides carbon sequestration. Besides delivering long-term carbon sequestration, it has been known for millennia that biochar also improves soil and increases food production.
The mild temperature in SkyClean pyrolysis leaves the nutrients in biochar readily available for absorption by new crops and makes biochar a highly attractive soil additive.
In recent years researchers have found biochar to possess a wide range of additional benefits for agriculture:
In addition to the benefits of biochar, SkyClean will also help agriculture lower emissions from methane. Methane is a much more potent greenhouse gas than CO2, and it accounts for a large part of emissions from agriculture.
The pyrolysis process of SkyClean eliminates methane from the feedstock and incorporates the constituent elements into the oil and gas fractions.
In total SkyClean offers significant and sustainable increases in agricultural productivity.
The technology offers a unique opportunity to implement game-changing climate mitigating initiatives in agriculture, while supporting sustainable productivity increase in both advanced farming economies and in low-tech agriculture in developing countries.
