Five-stars
This book was up to my expectations, and learned a lot more about biochar and its numerous potential.
Kathleen Draper, who is also the director at the Ithaka Institute and a member of IBI (International Biochar Initiative), both incredible resources on the subject is able to present with Albert Bates, the current ecological context we are in, and how to achieve offset man-made CO2 by sequestering it with biochar, in parallel with replanting trees.
Although it gets quite technical at times with calculations and numbers (how much giga-ton of CO2 offset, etc.), it's easily digestable material, with lots of varied information to get an overview of the potential of biochar.
Biochar under microscope: All those pores make an effective sponge (and habitat for microbial life)
For those that are new, biochar is essentially charcoal made from many various sources of carbon, including but not limited to bio-waste such as: wood, tree branches and leaves, agricultural waste (husks, cobs), kitchen scraps, manure, sludge, etc.) or even things like plastics although those seem a bit trickier. The process that differentiates biochar from your BBQ grill is through a process called
Pyrolysis, or burn in a low-oxygen environment. The result is not ash, but a solid chunk of black carbon. That stuff is black gold, and has many, many beneficial uses.
Too many to list them here, but one of my favourite is their sponge-like ability to absorb anything: Water, minerals, pathogens, and insulate heat, as well as EMF. It's quite common to have activated carbon filters for water filters (like Brita). So for instance, a biochar filter can be made to filter sewage water (or waste water from a production plant) it will then absorb and adsorb the minerals onto itself. Later, you can remove that biochar filter and now use it as a soil amendment, where all the nutrients sponged up will slowly be released for plants and soil organisms to feed on. For pathogens, it seems like they are de-activated (static charge?) so no concerns of spreading diseases that way.
One interesting pointed out, is that untreated biochar put on soil can suck in nutrients from plants and soil, thus decrease vigor for the first year or two. This is why it's necessary to treat the biochar with microbes and nutrients (which is where humanure or fermented tea, or previously treated water is useful)
Trees and plants love carbon, so they grow better, faster, stronger, and now you have more biowaste to use for further biochar production.
It's a cycle that keeps on giving, and what the author call, a carbon cascading effect.
In fact the biggest potential due to scale, is not as a soil amendment, but as a composite material in construction (concrete) as well as infrastructure (road making with asphalt) and as an industrial alloy (carbon fiber)
What I loved most about the book is it's larger vision, not just of using biochar, but of how
the social-economic dynamics will shift along.
Currency projects, like the
Nori, based on carbon-sequestrating initiatives (basically, you're paid the amount of carbon you've offset in the atmosphere) are interesting, and I wouldn't be surprised if soon, we'll have blockchain-based systems that tells you exactly where that char came from (what its made of). While still a gimmick, so were emails when first discovered, right? Time will tell!
Circular Economies are/will flourish thanks to the ability of DIY and/or accessible kilns (oven/stoves) that will enable local waste to be turned into biochar for many uses. I don't think I'm qualified to talk about the stove setups specifically, but to mention only one aspect: Stoves not only turn waste into biochar, but while doing so, the heat output can be used to heat buildings or hot water; energy can be turned into electricity; While there are CO2 and Syngas (synthetic gas) emissions from it, that can also be offset by the growing of
algaes (seaweed).
This is partly what the
City of Stockholm, Sweden, has decided to do with its parks waste. I hope a lot more will follow this example.
In fact, there's a great case to be made where Biochar, in tandem with algae can really close the loop, while producing abundant nutritious food.
Another one:
Bamboo grows super fast, and it's strong and durable.
How about growing bamboo, using clippings for biochar, while it can be used as building material for geodesic domes (habitats; gardens..). Kathleen also mentions her project using bamboo and biochar for compostable diapers (diapers again, from previous post) for her dog, though leaves out the "how".
Around me, and in general, I noticed how many small, local farmers in BC are strangled to earning any profits, working their asses off non-stop. But also noticed they don't necessarily consider the waste as a precious resource. At best, they would compost it (a waste in my opinion). Instead, turning your waste to grow mycelium and/or biochar is literally, the alchemical transmutation of poo into (black) gold.
But I'm already getting way too far into the bushes.
The book is highly recommended, and while I don't think it's a silver bullet for all our problems, combined with other platform technologies, like
water vortexing and
mycelium,
biochar may be one of the most versatile, best ways for eco-entrepreneurs to start a co-operative venture not to mention the relative low-initial capital investment required. Very inspiring stuff.
If you can't get the book but are interested, do check out Ithaka-Journal and IBI (links below), or Youtube for many videos on how to make your own biochar.
Oh and one last synchronicity before I leave, the book was dedicated to Hans Peter-Schmidt, and
Gunter Pauli! Going full-circle.
The future is/will be open-source; (networked) local, and symbiotic.
PS: this may sound foolish after talking so much about this, but perhaps the biggest learning lesson for me was the carbonizing process itself. Something as simple as
match-stick burning I took for granted my whole life, is actually very insightful (it's the ejected
gas burning; not the wood per se).
Fire, like Water, Soil, and Air, is an area I am only beginning to wake up to.
Banzai!

Also very interested in the work of
WorldStove, making cheap, easily-DIY'd cooking biochar stoves for home use. The only part that needs manufacturing is the vortex-spiraling top that allegedly mixes nutrients more effectively (makes me wonder if its the air equivalent of water vortexing?)
