Pig production contributes to sustainable technologies of the future
Is there climate potential in pig slurry? SkyClean is a piece of ground-breaking technology which, through a process known as pyrolysis (thermal decomposition of residual fibres from biogas plants and waste straw) can halve agriculture’s climate gas emissions. The technology can also supply fuel to the aviation industry.
The Danish Agriculture & Food Council, SEGES and a number of other partners are participating in a project with the potential both to reduce agriculture’s climate footprint and to supply CO2-neutral fuel to the aviation industry. Pyrolysis of surplus straw and residual fibres from biogas plants produces biochar which can be used to bind carbon in agricultural soil and increase the fertility of soil as fertiliser. Gas and oil are other residual products from pyrolysis process and can be used as CO2 neutral fuel.
SkyClean can deliver significant carbon reduction at low socio-economic cost
A report from EA Energy Analysis shows that SkyClean can deliver a substantial carbon reduction at a socio-economic cost lower than other alternative climate technologies.
Projected commercial roll-out of pyrolysis technology in 2023
SkyClean technology has significant future climate potential both in Denmark and internationally. Stiesdal A/S is the innovator behind the SkyClean project. The development of the pilot project got underway at the beginning of the year. At that time, it was announced there was still some way to go before the technology could be refined. Stiesdal A/S recently announced that the commercial rollout of the pyrolysis technology was expected in 2023. The SkyClean technology is predicted to offer great export potential.
