Conversion of biomass carbon (C) to biochar via carbonization (pyrolysis) offer a sustainable method for
managing organic residues and biomass. Depending on pyrolysis process, type of kiln and biomass,
carbonization can lead to sequestration of up to 50% of the C compared to the low amounts retained after
burning (about 3%) and composting (<10– 20% after 5–10 years)1. Gases from the pyrolysis process is burned
and the emission from the kiln is mainly CO2 - with much less soot than compared to conventional combustion.
The produced biochar is a stable product, highly resistant to microbial degradation. Up to 80% of the carbon
stored in biochar will remain after 100 years. In 2018 biochar was acknowledged by the IPCC as an important
Negative Emission Technology (NET) in the fight against climate change.
According to IPCC Fifth Assessment Report 2014 (AR5)2 in a 100-year time horizon the global warming potential relative to carbon dioxide (CO2) of methane (CH4) is 28 times and nitrous oxide (N2O) 265 times higher. Composting contributes to relatively large emission of methane and nitrous oxide. Animal husbandry is globally, together with the energy sector, the largest source of methane emission in a 100-year perspective. Incineration of biomass and organic contributes to emission of CO2, toxic carbon monoxide (CO), soot and other particle pollutants.
Therefore, converting organic waste to Easychar is the most eco-friendly way to deal with organic by-products.
