- The Institute for Carbon Removal Law and Policy presents a webinar on biochar: what it is, how it's made, and its role in carbon removal. The speakers also discuss biochar's co-benefits and side effects. Some other topics addressed include biochar in carbon finance, the persistence of biochar, and biochar's effects on soil and other greenhouse gases.
Panelists:
Johannes Lehmann, professor at Cornell University
Kathleen Draper, US Director for Ithaka Institute for Carbon Intelligence
Moderator:
Jason Funk- Fellow at Institute for Carbon Removal Law and Policy; Principal & Founder of Land Use & Climate Knowledge Initiative - Фільми й анімація
I make biochar in a wood stove in my basement. May not be the best quality, however it heats my house and I get to add biochar to my worm compost. I then share the end product with others. Not a large scale but if more people did this it would capture a lot of carbon.
Thank you for this great webinar! At the National University of Colombia, we work on research into the use of biochar for the adsorption of heavy metals and organic contaminants in soils. This information excites us very much.
Yes this fascinating to me as well. Charcoal has been used as a method of adsorption for toxins in the human gut after the ingesting toxins/poisons etc. Why would it act any differently in the soil. There are intresting papers that show it also has the ability to bind to carotenoids and Vitamin A which are commonly misunderstood as nutrients which they are not. Dr Anothy Mawson and Dr Garrett Smith have intresting things to add to this discussion.

Thank you for the great update!
From my perspective, very timely, as a co-manager of a small-scale community sawmill with three Kon Tikis being fabricated, and with the intent of charring some of our
~500 tonnes/yr potential feedstock of western red cedar & Douglas fir bark-on slab waste.
We will start by giving some to our neighbors. B., who has 550 chickens that stink, and D. with his acre or two of blueberries. Some of the crew at the mill have animals and gardens too, and we also get excited what it could do for the enhancement of local food production, but
our biggest neighbor is a huge commercial grower of forest tree seedlings, with natural gas-heated greenhouses, and is also the user of truckloads of peat that could be partially replaced with biochar.
So, I am very interested in how to get the heat in the greenhouse, because that’s a game changer. 🥑!
Kathleen, can you describe this method?
It would be hard for us to not go ahead with experimenting with all of this potential, but I would rather look to people that are specialists in this multidisciplinary field.
My big questions are:
Suitability of the char.
Inoculation strategy (I’ll probably try hot quench with chicken manure tea for my garden, but is that scalable or effective?)
How to design trials that include several steps from characterization of char, through to tree survival in the forest.
What role could carbon markets play
Moreover I am also looking to establish contacts for technical people that could guide trials and provide names for me to fill in on the funding applications.

My favorite technique to is simply dig a \_/ shaped channel about 6’ long, build up the material about 2/3rd of the way up and keep adding more material once it really gets going. From what I understand the coals can reach 600 degrees C pretty easy this way
Japanese Style. Works perfect. I don't want to know about the lg scale stuff and the goddamn govt thinking they know anything about a good law that benefits 1 person and harms no one. Your method I will add for the readers, quenches the char to extinguish the flame and heat... When you quench it hot at the end of the cook, you explode the char surface area into even more area, the steam tets into the pores, also it steams off a lot of the tar. Its multiple benefits to the char, and you can set it up so you charge some soil under the burn area with potash when you water it. Pre add some soil under the pit, it's more work but its free ash, washing out. Also for those worried about left over unburnt wood? The carbon your going to add to the soil with your biochar will still absorb enough nutrients when charging, so that it starts breaking down immediately, and the michorrizhae, and molds, and fungus will come and, the biochar will take them in as well later, and forevermore. People worry too much. I use Royal Oak Natural Wood charcoal, I know some of its not done, but, so what? Most of it is. The tar? My biology will devour it up in no time. I am also talking about lawn applications, not garden. So I play the long game, years to set and be incorporated, by worms. I use a scarifier to open the top soil a bit, it does no harm, like a rototiller or garden weasel. Spring and fall applications, because its too hot in summer. Biology will dry out, and not establish. Grass does its growing here in Canada in spring and fall. I hope I helped a bunch of people, as I know new folks are finding out about Biochar every day, and ending up here eventually if they are crazy like Me.
Make the biochar from the charcoal produced in a gasifier and you'll have an excellent soil additive and create combustible gases from the gasifier to use in power generators. A perfect closed loop renewable energy solution!!! :-)
So what I have gotten out of this webinar is that biochar needs to be made in a 0 oxygen environment and at a high tempature up to 600⁰C. The higher the tem up to max the more president the biochar. The heated biochar feed stock produces gasses and condensates that are useful. These condensates and gasses can be used as fuel to make the biochar or for products themselves. These by products reducing the cost of Biochar. Biochar is being shown to increase crop yields with or with out fertilizer inputs. Biochar plus synthetic fertilizers produces a considerable greater crop yield benefit that syn fert alone. Farmers may also be paid for applying biochar as CO² removal credit as well soil toxin removal. Can also be added to livestock feed as a benefit to the livestock and a way to get into soil through manure. Do I have this mostly right?
Great discussion and helpful information.
How can I access the papers ?

I am confused about my presentation for bio char don't know how to make plants table slides
Are there sources of waste heat that would be sufficient to drive the pyrolysis needed to create biochar?
Howdy-I personally will be manufacturing a 'Biogas Generator' and from that polishing the methane gas to CNG(methane gas) to fuel the pyrolysis for biochar.....hope this helps......
Yes . Only initial external heat is required . After that it's a self sufficient system
I think I understand the "big picture" benefits of biochar, especially in barren soils. However, I fail to see actual or signifcantly, measurable benefits to home vegetable gardeners with normal, healthy soil. Perhaps I'm wrong and while I read a lot of anecdotal claims, I have yet to find a peer-reviewed field trial that shows improved results.
I agree but have used with success. I believe that most of its benefits come from binding to toxins in your soil. Long discussion but animal manure for example contain toxins that the animals filtered out of their blood stream processed through the liver and pooped out. Could be heavy metals such as arsenic, chromium, Cooper, lead etc. I use in my composting process with great results
Whats the best biochar size for sandy soil
I too would like to know the answer to this question
I would think anything under 1/4” would be best! Larger sizes could also be of benefit, even partially charred chunks of wood would be good... just soak the wood char in something first
2mm to 4mm
Is this PBS?
Thanks for nice seminar....I am from Pakistan....I am interested to join your team...my work were related to the biocarbons
R u in biochar related work ?

Can biochar and compost be used to rebuild the desert? or does it take more.
It can help, look up videos on Allan Savory desertification is kinda his jam.
greening the desert - look it up in youtube, lots of them. biochar's place in the effort? looks superfluous if the techs we are shown are effective. even in mainstream ag, biochar has not spread like the wildfire it is in the minds of many. but it has a place in particular farms. we will trial using it with our papayas in our farm here in the Philipines - soils are acidic, low in organic matter, kind of high in CEC, when it rains, it pours (and papayas do not like stagnating water) and in the summer which has just began, it is really really hot. blessings to all
You may also want to research miconized liquid clay in addition to biochar. It is in use in Australia, but I can't remember the application rate.
Please consider upgrading your microphones. There are plenty of good ones in the $150-$200 range. Covering hard flat surfaces with egg crate, moving blankets and/or sound damping panels would further improve sound quality.
Didn't get much knowledge of the subject
Which subject? The video is about The Institute for Carbon Removal Law and Policy
These stories are way to long, to much talking.
Play them at 1.5x speed, much quicker. I play all YT vids at 1.25x but this one you can still understand at 1.5x
@@FlakeyPM i will look it up to figure out how to increase speed. I agree that many especially in academia take 20 sentences to say 2 key sentences lol. So i appreciate your suggestions
