"plants or biomass absorb CO2 and are cooked into biochar, locking it in instead of having the plants rot and return the CO2 to the atmosphere. It is essentially pulling carbon out of the air." How much CO2 is released by the fuel used for the cooling process?
Hi Lloyd, thanks for your work, and I look forward to your book this year! My understanding is that A5 emissions are easily in the 15% range for total embodied carbon, and possibly more. I'm always looking for stories on how to reduce the carbon intensity of on site construction. Electrifying equipment seems like a great option - and I look at things like the City of Vancouver's Public Realm Electrification Program and see that it could be for more than just film and food trucks. https://vancouver.ca/green-vancouver/public-realm-electrification-program.aspx
I’m fascinated by the biochar process, but wonder about the adage that we need to stop burning things. How much is the burn process releasing carbon and pollutants. Are the pfas and other chemicals released into the air in the process or are they destroyed? That said do you know if this product is something that could be mixed into garden soil to condition it? I would love to use something like this in my garden, if it was safe.
I went to a permaculture meetup about making your own biochar for use in the garden. As I remember (it's been a while), as long as it is 'clean,' and used in the right proportions, it's supposed to be beneficial.

My understanding is that they use biogas generated in the process, and about half of the CO2 is lost in that process and half is turned into biochar.
Congrats on 2,000 subscribers! Keep up the great work.

Not all biochars are equal, apparently, and some would not be good for gardening:
