Host Shayle Kann and Charm Industrial CEO Peter Reinhardt discuss transforming agricultural residues and forest thinnings into dense bio-oil for permanent carbon removal. They examine the logistical challenges of biomass hauling, the advantages of mobile in-field pyrolysis, and the growing corporate market for high-durability carbon removal.

speaking balance: gold is Shayle, purple is the guest (3 minute bins)
Sharpest disagreement ▶ 4:30 Pushing back on the 'waste' label
Reinhardt politely but immediately corrects Kann's framing, rejecting the premise that agricultural residues are merely waste rather than high-value underutilized carbon resources.
Hardest push from Shayle ▶ 17:05 Questioning mobile pyrolysis scale penaltiesKann challenges Reinhardt's core operational thesis, asking directly whether opting for small mobile pyrolysis units sacrifices the significant cost advantages of 10x industrial economies of scale.
Biggest teaching moment ▶ 11:05 Demystifying transport constraints: volume vs weightReinhardt corrects Kann's assumption about hauling water weight, demonstrating that corn stover transport is constrained by volumetric fluffiness ('cubing out') rather than tonnage limits.
Shayle holds their own ▶ 26:31 Exposing policy-driven ethanol market distortionsKann demonstrates sharp market expertise by explaining that past biomass usage in ethanol was driven by artificial tax credit incentives rather than rational energetic value.
the scores for every segment, with the reasoning behind each
| Chapter | Topic | Shayle as informed peer | Guest teaching | Guest disagreement | Shayle pushing back | Why |
|---|---|---|---|---|---|---|
| Understanding Agricultural Residue and Corn Stover Scale | 4 | 5 | 2 | 1 | Kann sets up the ag waste landscape with high-level questions. Reinhardt gently reframes Kann's terminology from 'waste' to 'underutilized residues' and walks through the agronomic scale and soil moisture differences of corn stover across US regions. | |
| Logistical Realities of Biomass Gathering and Transportation | 6 | 5 | 1 | 2 | Kann probes on biomass pricing in bone dry tons and the penalty of transporting dead weight. Reinhardt educates him on how corn stover economics are actually dominated by volumetric space ('cubing out') rather than water weight, while sharing field realities of baling edge cases. | |
| Mobile Pyrolysis Units Versus Centralized Processing Facilities | 6 | 4 | 1 | 3 | Kann lays out the fundamental trade-off between centralized economies of scale and distributed mobile processing, pressing Reinhardt on whether 10x pyrolysis scale would be cheaper. Reinhardt defends Charm's mobile combine thesis with Capex per ton benchmarks and unique surface area scaling laws. | |
| Sponsor Messages: Bloom Energy, Engie, and Energy Hub Mid-Roll | 6 | 3 | 1 | 2 | Following the mid-roll ad read, Kann and Reinhardt analyze highest and best uses of biomass, noting biomass is energy-poor but carbon-dense. Kann interjects informed context on historical ethanol market distortions and co-firing incentives. | |
| CDR Market Maturation, Customer Motives, and Verifiable Impact | 6 | 4 | 1 | 2 | Kann draws on his 15-year background in voluntary carbon markets to dissect buyer dynamics. Reinhardt shares his experience as a frustrated legacy offset buyer, outlining Charm's radical delivery transparency and corporate marginal abatement thresholds. |

Kann: DOE estimated US ag residue at ~200M dry tons annually
“There was a DOE study a couple years ago that estimated the amount of ag residue alone, that's a subset of this category, at around two hundred million dry tons per year.”
Reinhardt: US corn generates roughly 400 megatons of unused stover annually
“There's about 90, ninety-five million acres of corn grown in the US every year. There's order magnitude four dry tons of stover per year on each of those on each of those acres, and so, you know, you're, Just on corn stover, you're looking at 400 megatons of a…”
Reinhardt: Charm plans to operate in-field to eliminate hauling costs
“Something that we're trying to invert, invert this at Charm by eventually Operating on field to cut this all out.”
Reinhardt: Abengoa Hugoton failed due to $120/ton biomass transport costs
“Abingoa Hugotin was a huge cellulosic ethanol plant that failed in Western Kansas because they were trans, transporting their biomass, 50 to a hundred miles. They expected to pay maybe 60 dollars a ton. They found, in fact, that they were paying, like, north o…”
Reinhardt: Corn stover transport cost is limited by volume, not weight
“When you're trying to transport Stover, you cube out, meaning volumetrically, you run out of space a lot faster than you weigh out.”
Reinhardt: Wildfire thinning wood biomass often has 50% water content
“Wood can easily be 50% water if it's young growth and, you know, hasn't aged for a year post cutting. So when you look at like wildfire thinnings, for example oftentimes we get wood that's in the 50% range. And there, yeah, it sucks, because half of what you'r…”
Reinhardt: Fixed pyrolysis facilities break unit economics compared to mobile units
“When you start moving away from a mobile piece of equipment into a fixed facility, You do get some economies of the construction, but you actually take on a lot more risk in every facility that you build. You have all the balance of plant, you have permitting,…”
Reinhardt: Charm's capex per ton is under half of state-of-the-art pyrolysis plants
“If we look at the capex, for example, of our system today on a, Per dollars capex per ton basis, and compare it to, say, like, state-of-the-art pyrolysis facilities, we are already less than half of that cost on, on a dollar per capex basis, and that will decl…”
Reinhardt: Biomass is best utilized for carbon content, not energy
“What's interesting about it is that relative to almost everything else, it's very carbon rich. And so the use cases that rely either on the chemical availability of carbon or on, ah, the sort of physical availability of carbon, those, or like in the case of ca…”
Kann: Microsoft and Frontier dominate virtually all carbon removal purchases
“If you just look at, like, overall
Tons purchased in the CDR market.
It's basically Microsoft, followed by, like, an order of magnitude lower frontier, which is the Stripe Coalition, followed by a bunch of little minnows, you know, in, in relative terms.”
Reinhardt: High EBITDA per ton companies will lead carbon removal adoption
“If you look at a sort of chart of, like, profitability per ton or EBITDA per ton, like, it's the companies that have a lot of EBITDA per ton that are going to lead the way on helping things down.”
Reinhardt: Removing carbon is cheaper than $2,000/ton building decarbonization retrofits
“It's gonna cost, like, 2000 dollars a ton for me to go, like, tear down a building and rebuild it with, like, a proper HVAC system that does, like, heat pumps, you know, it's like, and have clean concrete, like, you know, at some point you get down to this, li…”
