Phil Stevens :tinoflag:So I'm doing A Thing later this month. If you're in the Manawatū or adjacent regions, it's an excuse to stand around a fire and have a yarn. <a href="https://mastodon.nz/tags/biochar" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#biochar</a> <a href="https://mastodon.nz/tags/regen" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#regen</a> <a href="https://slowfarm.co.nz/blog/2025-field-day" rel="nofollow noopener noreferrer" translate="no" target="_blank">https://slowfarm.co.nz/blog/2025-field-day</a>

New research suggests it stays trapped for much longer than scientists thought.""For all its plant and animal life aboveground, the Amazon rainforest’s soils are surprisingly poor in nutrients necessary for growing food. Thousands of years ago, the region’s Indigenous peoples solved this problem by creating “terra preta” from table scraps and charcoal and tucking it away in the hostile soil.""As biomass like trees and crops grow, they sequester carbon in their leaves and branches. Heat that biomass up without fully consuming it and it turns to nearly pure carbon known as biochar,""The nagging question, though, is exactly how long that carbon stays in the soil. A new study adds to a growing body of evidence that scientists have been underestimating the staying power of biochar, meaning the technology is actually an even more powerful way to store carbon than previously thought.""Nailing down exactly how long biochar can hold onto carbon is crucial for the carbon-removal credit industry, where companies like Microsoft and Google fund projects to draw carbon out of the atmosphere.""Much as humans eat food off dishes instead of eating the dishes themselves, bacteria and fungi choose to eat organic matter like leaves over biochar. “It’s kind of like if you have a nice piece of cake and they bring it to us on a plate, we’re going to eat the cake,” Sanei said. “If we are very hungry, we eat it much faster. But still, we’re not going to eat the plate.”<a href="https://climatejustice.social/tags/TakeCareForLife" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#TakeCareForLife</a> <a href="https://climatejustice.social/tags/TakeCareForEarth" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#TakeCareForEarth</a> <a href="https://climatejustice.social/tags/StopBurningThings" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#StopBurningThings</a> <a href="https://climatejustice.social/tags/StopEcoside" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#StopEcoside</a> <a href="https://climatejustice.social/tags/StopThePlunder" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#StopThePlunder</a> <a href="https://climatejustice.social/tags/ClimateBreakDown" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#ClimateBreakDown</a> <a href="https://climatejustice.social/tags/StopRapingNature" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#StopRapingNature</a>

Hippy SteveWay to go Minneapolis!Minneapolis to Open North America’s First City-Run Biochar Facility <a href="https://biochartoday.com/2025/03/12/minneapolis-to-open-north-americas-first-city-run-biochar-facility/" rel="nofollow noopener noreferrer" translate="no" target="_blank">https://biochartoday.com/2025/03/12/minneapolis-to-open-north-americas-first-city-run-biochar-facility/</a>Cities generate large amounts of wood waste from tree removals due to pests, disease, and infrastructure maintenance. Without intervention, this waste decomposes and releases carbon dioxide into the atmosphere. Minneapolis’ new facility aims to reduce emissions by capturing carbon in <a href="https://m.ai6yr.org/tags/biochar" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#biochar</a> which remains stable in the soil for over a thousand years. Each year, the facility is expected to:Process over 3,000 tons of wood wasteProduce more than 500 tons of biocharRemove nearly 3,700 tons of CO₂ from the atmosphere, equivalent to taking 789 cars off the roadBy turning waste into a long-term climate solution, Minneapolis is demonstrating how cities can integrate carbon sequestration into their waste management strategies.<a href="https://m.ai6yr.org/tags/permaculture" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#permaculture</a>

Phil Stevens :tinoflag:<a href="https://mstdn.social/@samhainnight" class="u-url mention" rel="nofollow noopener noreferrer" target="_blank">@samhainnight</a> If you heat with wood, ashes are another good way to raise soil pH. As a bonus, there might be a little bit of <a href="https://mastodon.nz/tags/biochar" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#biochar</a> in there and that will help fertility over the long haul.

Phil Stevens :tinoflag:Yes, this risk has always been there and it's one of the main reasons CCS is a stupid idea.Aside from the eye-watering capital cost and miserable ROI of every one of these projects, does anyone really think the companies that deploy this are going to stick around for centuries in case the CO2 doesn't?Once again, photosynthesis plus pyrolysis wins and <a href="https://mastodon.nz/tags/biochar" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#biochar</a> says "hold my beer."<a href="https://theconversation.com/leakage-is-a-risk-with-carbon-storage-projects-nzs-new-framework-must-be-clear-on-how-to-deal-with-this-liability-251006" rel="nofollow noopener noreferrer" translate="no" target="_blank">https://theconversation.com/leakage-is-a-risk-with-carbon-storage-projects-nzs-new-framework-must-be-clear-on-how-to-deal-with-this-liability-251006</a>

Kirk Smith, PhDHey <a href="https://mastodon.nz/@phil_stevens" class="u-url mention" rel="nofollow noopener noreferrer" target="_blank">@phil_stevens</a>, curious if you have any thoughts or resources you might want to share on the state of <a href="https://social.coop/tags/biochar" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#biochar</a> entrepreneurship these days! I saw a biochar company pop up in a neighboring state to mine and was wondering about biochar co-op business models. Context: a state with forestry and agricultural residues (Missouri)

Phil Stevens :tinoflag:<a href="https://beehaw.org/u/I_am_10_squirrels" class="u-url mention" rel="nofollow noopener noreferrer" target="_blank">@I_am_10_squirrels</a> <a href="https://slrpnk.net/u/ProdigalFrog" class="u-url mention" rel="nofollow noopener noreferrer" target="_blank">@ProdigalFrog</a> There is more to it than just molecules getting "trapped in pore spaces" and it's a little complicated.Activated carbon (and its more affordable, carbon-sequestering cousin <a href="https://mastodon.nz/tags/biochar" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#biochar</a>) has functional attachment points on the edges of ring and plate molecular structures. These can attract and retain some substances from solution.But the real fun happens when we add dopants. Other molecules present in the carbon matrix supercharge the chemical potential.1/2

Nearly all coal deposits predate the chance mutation that gave white rot fungi the superpower of making an enzyme to break down lignin. Now the only coal that can form in nature is in acidic peat swamps that inhibit fungal activity.This is why we need to be making "reverse coal" ourselves in the form of <a href="https://mastodon.nz/tags/biochar" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#biochar</a>.

Kevin LeecasterI know that I have a steep hill to climb in order to help Carbon Dioxide Removal <a href="https://mstdn.social/tags/CDR" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#CDR</a> recover from the damage the <a href="https://mstdn.social/tags/FossilFools" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#FossilFools</a> and just plain grifters have done to the reputation of Direct Air Capture <a href="https://mstdn.social/tags/DAC" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#DAC</a>. I'm hoping that the tangible product <a href="https://mstdn.social/tags/BioChar" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#BioChar</a> can help to convince people to reconsider DAC for CDR.The demonstrated recalcitrance of terra preta and ability of any and every farmer/gardener to manufacture and sequester it makes it one of my favorite approaches. <a href="https://www.science.org/doi/10.1126/sciadv.adh8499" rel="nofollow noopener noreferrer" translate="no" target="_blank">https://www.science.org/doi/10.1126/sciadv.adh8499</a>
