Take: The palm nutcracker that became a carbon dioxide removal company—w/ Uzoma Ayogu of Biochar Industrial Group

Take on a podcast episode from Reversing Climate Change, originally published Thu, 24 Se. Listen: https://podcasters.spotify.com/pod/show/reversingclimatechange/episodes/The-palm-nutcracker-that-became-a-carbon-dioxide-removal-companyw-Uzoma-Ayogu-of-Biochar-Industrial-Group-e3p96kt TL;DR BIG’s model: don’t build greenfield biochar plants; bolt pyrolysis onto existing agroprocessors who already have feedstock, permits, weighbridges and farmer trust. Sound framing. Value split is 20/60/20 of carbon profit (BIG / partner / capex funder); 80/20 early when BIG carries the risk. Rare to hear the terms stated. Target fully loaded removal cost of $50–70/t. Stated as a goal, not a demonstrated number — treat accordingly. Pyrolyzer uptime went 38% → 87% in a year; two larger systems due end-2026 and Q1 2027. Cassava trials: 21–50% yield gains on acidic soils (pH 4.5–5.9). Promising but small, self-reported, and only ~20% of physical biochar sold so far. Ross Kenyon hosts Uzoma Ayogu, CTO of Nigerian palm-kernel processor Releaf and cofounder of its spinout Biochar Industrial Group (BIG), which just closed a pre-seed round. The episode traces how a decade-old agri-supply-chain business ended up issuing Nigeria’s first industrial biochar credits, why the carbon dioxide removal (CDR) arm had to be a separate entity, and what BIG now offers other West African processors. ...

Captain's CDR Log #274: ADM's 800,000 tonnes and the retrofit plants now setting durable CDR supply

Captain Drawdown’s daily logbook on every CDR story, paper, and expert voice — so you don’t have to read them all. The forecast: operating retrofits, not new builds, will supply most durable tonnes buyers can actually receive through March 2027 Durable CDR volume over the next six months will come mostly from plants that already run. ADM’s Nebraska bioethanol capture operation, now offering credits through Puro.earth at 800,000 tonnes per year, is the clearest case. Its Columbus facility opened in 2025 on more than a decade of ADM capture experience, so the operator risk (does the compressor run, does the well accept CO2, does the meter agree with the model) is largely behind it. New-build developers face all of that risk ahead of them. The practitioner’s question is not who has the best process. It is who can hand a registry verified tonnes this year. And the answer is retrofit plants. ...

CDR Daily Digest — 2026-09-30

The buyer side of CDR got wider today, not deeper. A national government made its first purchase, a software company funded eight pre-purchases through an intermediary, and three enhanced weathering papers landed at once. None of the money is large. The pattern is that the people writing cheques are no longer only the handful of tech firms that started the market. The UK government bought removals for £783,749, and the amount is the least interesting part Captain Drawdown’s daily CDR Log #273 covers the UK government’s first turn as a carbon removal buyer, a purchase worth £783,749. Set against the tens of millions in a single Microsoft or Frontier Climate offtake, that figure is a rounding error. So the size is not the story. ...

Pathway 101: Registries & Standards

A registry is the ledger. A standard is the rulebook. For carbon dioxide removal (CDR), they are what turns “we removed a tonne of CO₂” into a serialized credit that someone can buy, count, and retire. A standard defines what counts as removal and how it must be measured. A methodology applies those rules to one specific process. Independent auditors check the project against the rules, and the registry issues the unit and tracks who owns it. When a buyer asks whether a credit is trustworthy, they are really asking whether each of these layers did its job. When a lender asks whether a project is bankable, much of the answer depends on whether a recognized standard has a methodology that fits the project’s process. ...

Salesforce backs Milkywire's eight new durable CDR pre-purchases

Carbon Herald just published Milkywire Completes Eight New Durable CDR Pre-Purchases Backed By Salesforce. Carbon Herald reports that Milkywire, the Swedish climate platform that pools corporate funds for early-stage carbon removal, has finalized a fresh round of durable CDR pre-purchases. The round is supported by Salesforce and covers eight separate agreements with durable removal projects. Pre-purchases of this kind pay suppliers ahead of delivery to help them scale and reach first tonnes. The outlet frames this as a continuation of Milkywire’s model of channeling corporate money into a portfolio of durable pathways rather than a single project. The headline and summary do not spell out the supplier names, the tonnage contracted, the pathways involved, or the total value of the round, so readers will want to check the full article for those specifics. ...

Captain's CDR Log #273: £783,749 and the UK government's first turn as a carbon removal buyer

Captain Drawdown’s daily logbook on every CDR story, paper, and expert voice — so you don’t have to read them all. £783,749.20. That is the value of the tender Climeworks won from the UK government to offset emissions from a construction project, reported by Quantum Commodity Intelligence at roughly $1.04 million. The state was a rule-setter. Now it is also a buyer. Until this award, the UK’s role in removals ran through targets and frameworks. A Nature Climate Change paper notes that the UK is the only country that explicitly separates emissions reductions from removals, and that it carries a 5 MtCO2 deployment target for novel CDR by 2030. That target tells suppliers what the government wants to exist. It does not put money on a contract. ...

CDR Daily Digest — 2026-09-29

Today’s three stories point the same way: the binding constraint on CDR is shifting from capture to everything downstream of it. Where does the CO2 go, who is actually paying for it, and who does the work. Austria is writing a law for the first question, CDR.fyi’s market data answers the second, and a headcount of 12,351 people across the 12 largest CDR companies gives a first rough answer to the third. None of the three is about a new machine. ...

12 largest CDR companies employ 12,351 people across pathways

This is a horizontal bar chart ranking the twelve largest pure-play CDR companies by employee headcount, with each bar coloured by the primary removal pathway the company pursues (DAC, mineralisation, biomass, ocean, and so on). Pure-play means the company’s core business is carbon removal, not a side project bolted onto an existing industrial firm. For anyone tracking the sector, this is the quickest way to see where the human capital actually sits. Headcount is a slower, harder signal than press releases or announced offtakes - it reflects real hiring, real payroll, real conviction from investors. The pathway colouring shows whether the talent concentration lines up with where delivered tonnes are going, or whether one approach is staffing up well ahead of its removal track record. ...

Captain's CDR Log #272: Austria's draft CO2 Storage Act and the landlocked case for storing at home

Captain Drawdown’s daily logbook on every CDR story, paper, and expert voice — so you don’t have to read them all. Austria has published a draft law to end a storage ban that has stood since 2011 Austria, a country with no coastline and no offshore storage of its own, has published a draft Kohlenstoffdioxid-Speicherungsgesetz, a CO2 Storage Act that would lift the national ban on geological CO2 storage in place since 2011 (Europe Says). It is a draft. Permitting conditions, scope and timing are not settled, and no developer can treat it as a legal basis for injecting a single tonne yet. But the direction is what matters. For fourteen years the legal answer to “can captured CO2 stay in Austria?” was no. The draft reopens the question, and the coverage reads it as a removal story, specifically an opening for bioenergy with carbon capture and storage (BECCS), rather than only a fossil-plant capture story (Bytes Europe). That is the right reading for a landlocked country. ...

Captain's CDR Log #271: Canada builds CDR to export tonnes while the EU builds it to absorb them

Captain Drawdown’s daily logbook on every CDR story, paper, and expert voice — so you don’t have to read them all. The question: who buys a removed tonne, and where do they live? Canada and the EU now give opposite answers. On 2026-09-24 Canada said it will develop a carbon removal policy framework under Article 6 of the Paris Agreement, the article that lets countries cooperate on their national climate targets, according to Reuters. The European Commission’s proposal to bring permanent removals into the EU Emissions Trading System (ETS) predates that announcement. What landed alongside the Canadian news was a joint statement from five European removal associations welcoming the proposal and pushing for design changes (Carbon Herald). So these are not two governments moving in step. One is announcing intent, the other is already arguing over clauses. The direction still contrasts cleanly: Ottawa treats removals as an export, Brussels as a domestic compliance input. ...
