Global warming has worsened in the past years with the feared effects getting more frequent, including floods, droughts, oceans rising and other challenges for populations worldwide. While climate conferences aim at limiting Green House Gas emissions (GHG), The emissions have risen between 1990 and 2010 with a rate of 0,667 GT COeq per year in addition. Therefore, it seems more and more appropriate to remove CO2 from the atmosphere. While Direct Atmospheric Carbon capture (DAC) methods are evolving, the real long-term way seem to be pyrolytic methods (PYCCS), as described by the Potsdam climate research center described in 2022. Pure carbon, which is not burned, but utilized as a soil enhancer can remain in the soil for up to thousand years.

One question that has to be solved is, which pyrolytic kiln or more specifically device should be utilized more appropriately for sequestrating biomass, and more specifically, biomass waste. In locations, where sufficient biomass is growing captivating CO2 into plant material, the infrastructure is not easily permitting transport of biomass. In tropical countries, the perspectives to efficiently locating pyrolytic devices are promising. However, some emissions are needed to reach sufficient temperature to pyrolyze, because a straightforward fire is started initially. Once the pyrolysis is initiated, for each ton of Carbon sequestrated, 44/12 = 3,6 Ton of CO2 is removed from the atmosphere, theoretically. Here in this study these GHG are estimated for two and measured for at least one kiln and put into a climatic “cost-benefit” analysis. CH4, NOx, CO and CO2 are recorded over the pyrolytic process’s time and integrated to obtain a balance of GHG emissions that must be accounted against the imissions or sequestrated carbon. A method is developed to perform observations of carbon output, gas emissions and wood vinegar. The latter is not counted as sequestration because the pyrolytic acids will take part in plants metabolism processes. Based on the methodology, two kilns are measured, which allows comparing the pyrolytic devices.
