Carbon removal (biochar & agtech). Applied Carbon builds automated machines (“farm robots”) that convert agricultural waste biomass into biochar, sequestering carbon and improving soil health. These machines are essentially mobile pyrolysis units that can be brought directly to farms they heat crop residues (like corn stalks, rice husks) in a low-oxygen chamber, turning the plant carbon into stable biochar (a charcoal-like substance) instead of letting it decompose or burn. The biochar, when added to soils, locks the carbon away for hundreds to thousands of years and also enhances soil fertility by retaining nutrients and water. Applied Carbon’s innovation is making these units small and autonomous enough to move from field to field, operating affordably at the point of waste generation. This avoids costly biomass transport and can run on energy from the crop residues themselves.

Early growth (Series A). The company recently raised a $21.5M Series A (mid-2024) led by TO Ventures, with participation from Anglo American, Microsoft’s Climate Innovation Fund, S2G Ventures, Autodesk Foundation, Elemental Excelerator, Grantham Foundation, and others. Prior to that, it won grant awards including a $500k Wilkes Climate Prize and had $4M in seed funding from Congruent Ventures and Susquehanna Foundation. In total, Applied Carbon has raised around $25M+ to date. With the Series A proceeds, it is building a fleet of its biochar machines to be deployed in Texas, Oklahoma, Arkansas, and Louisiana in partnership with large farming operations. These units will generate revenue by selling high-quality carbon removal credits and potentially biochar co-products. The Company has recieved term sheets for $5-$20MM in non-dilutive project and equipment finance to scale it's growth. In parallel, the company is now raising a $5-10MM Series A Extension alongside this project finance facility.

Each Applied Carbon pyrolyzer can produce up to 500kg of biochar per hour, capturing ~1 ton of CO₂ equivalent (net) in that biochar. It is towed by a standard tractor and powered partly by the syngas byproduct of pyrolysis. The plan is to deploy 60 machines by 2027 across four states (as mentioned), which would sequester on the order of hundreds of thousands of tons of CO₂ per year collectively. The company has inked a partnership with USDA NRCS, the US agency tasked with soil conservation, to provide crop residue feedstock and land for field trials. It has also secured a multi-million dollar offtake agreement with Microsoft to purchase some of the biochar credits once verified, and with Shopify’s Sustainability Fund for early credit purchases. The Puro.earth registry is working with Applied Carbon to develop a new biochar credit methodology, ensuring the credits are high-quality and tradable. The team is led by CEO Jason Aramburu, an experienced social entrepreneur who researched biochar at Princeton and previously founded a soil analytics startup. Team size ~20, including engineers from agri-machinery companies and soil scientists.

Biochar is recognized by the IPCC as a viable carbon removal method. Applied Carbon’s approach could lock away significant carbon while also displacing emissions that would occur if residues were burned or left to rot (which emits CO₂ or methane). Each machine in the field can sequester ~5,000 tons of CO₂ per year (roughly the emissions of 1000 cars) by continuously processing farm waste. Biochar also can reduce the need for synthetic fertilizers by improving soil, which in turn cuts nitrous oxide emissions from fields. If Applied Carbon reaches its goal of hundreds of machines across global farm belts, the climate impact scales for instance, the U.S. generates hundreds of millions of tons of ag waste annually – converting a fraction of that via Applied Carbon could remove on the order of tens of millions of tons of CO₂ per year. Furthermore, by creating a new income stream for farmers (selling carbon credits), it incentivizes sustainable agriculture practices. Importantly, the permanence of biochar is high – carbon is stored in a stable form in soils (some fraction remains for centuries). Thus, credits from Applied Carbon are likely to be viewed as “high durability” removals by offset buyers, aligning with the need for long-term climate benefits.

The Series A included heavy hitters TO Ventures led, signaling confidence from large institutional capital. Anglo American’s investment suggests interest in biochar for land reclamation or scope 3 offsets in mining (and indeed Anglo American may use biochar to offset some of its operations’ emissions). Microsoft’s Climate Fund being involved ties to Microsoft’s commitment to carbon removal (they could be a future buyer of credits). S2G (agri-food tech VC) brings deep connections in the farming sector. Partnerships It’s working closely with the University of Texas A&M on soil trials to quantify crop yield benefits from biochar (to help pitch the agronomic value to farmers). It was a part of the Elemental Exceleratorprogram, through which it partnered with growers to test on sugarcane waste. Additionally, the company is in discussions with major grain producers in the Midwest to line up feedstock and land for the next phase of deployments. On the carbon finance side, Applied Carbon is collaborating with Carbonfuture (a platform for biochar credits) to track and sell its credits in the voluntary market once verified. These backers and alliances provide not just funding but validation and channels to scale (farmer networks, credit marketplaces, etc.).

Mobile, distributed approach – rather than building one large centralized biochar plant, Applied Carbon’s small-scale units can go wherever the biomass is. This is cost-effective because agricultural residues are bulky and costly to transport; handling them on-site is a big advantage. It also means deployment can be highly modular and fast (mass-produce the units and send them out). The company estimates it can produce biochar at around $39/ton of CO₂ or less at scale, which is competitive for engineered carbon removal. Another differentiator is the automation these robots are designed to run with minimal human oversight (they can be managed by a single operator overseeing multiple units remotely), which lowers operating costs vs. traditional biochar operations. Applied Carbon is also focusing on durability and measurement – by embedding sensors and using data models to ensure each batch of biochar is quantified and stored properly, they aim to make their carbon credits extremely trustworthy, which not all offset projects achieve. Finally, the dual value proposition (carbon credits + soil enhancement) sets it apart they are not just in the carbon business, but also potentially selling or delivering biochar to farms for agronomic use, which could become an additional revenue stream or at least encourage farmers to participate (they get soil benefits).

One risk is operational running a fleet of machines on farms means dealing with harsh field conditions, maintenance challenges, and the variability of biomass. Applied Carbon must prove the reliability of its machines and perhaps establish a service model (like how farm equipment dealers support tractors). Another risk verifying carbon storage at scale – they will need robust MRV (Measurement, Reporting, Verification) to satisfy credit buyers that the char stays in the soil and doesn’t get disturbed. However, biochar is relatively easy to track compared to, say, forest offsets. On the opportunity side, the voluntary carbon market is increasingly interested in high-durability removals, and Applied Carbon is positioned to supply that. It already has multiple interested buyers (demand likely outstrips their near-term supply). Moreover, as climate policies evolve, there could be subsidies or carbon price incentives for farmers to char their waste instead of burning (e.g., in California, burning ag waste like rice straw is being regulated – this could push them to adopt solutions like Applied Carbon). The company can also tap into the $200B+ agriculture industry by framing biochar as a service improving yields, drought resilience, and reducing fertilizer costs for farms – these co-benefits can drive adoption even without carbon credit income. If Applied Carbon scales successfully, it not only becomes a profitable enterprise (selling credits perhaps at >$100/ton while driving costs down, capturing a nice margin) but also a decentralized climate solution empowering farmers. In summary, it has the opportunity to turn farms into carbon removal factories at scale, an appealing vision marrying climate action with agricultural sustainability.
