minus-squareGaywallet (they/it) ( Gaywallet@beehaw.org ) OPlinkfedilinkarrow-up13·3 years ago It seems unfair to say that we’re saving on CO2 and methane from decomposition without also counting the cost of the biochar combustion. Biochar is still a pretty new concept, but results are promising as a potential overall carbon negative process.
