Exomad Green, a Mongolia-based biochar company, and China’s Beston Group have entered a new phase of their strategic partnership aimed at scaling up biochar production capacity. The deal deepens an existing collaboration between the two firms and represents one of the more notable cross-border partnerships in the biochar-based carbon removal sector, linking Chinese pyrolysis technology with Mongolian feedstock and deployment.
Why It Matters
Biochar is one of the more commercially mature forms of durable carbon removal, but the sector’s biggest bottleneck remains production capacity. Most biochar operations today are small-scale, often producing hundreds or low thousands of tonnes per year. Partnerships that pair technology manufacturers with deployment-focused companies are exactly the kind of supply chain integration the sector needs to move from niche to meaningful scale. The China-Mongolia corridor is particularly interesting because it combines low-cost manufacturing with vast, underutilized biomass resources.
The Details
Beston Group is a Henan Province-based manufacturer of pyrolysis equipment, including biochar production lines, waste tire recycling plants, and biomass carbonization systems. They’re not a household name in Western CDR circles, but they’re one of the larger Chinese producers of the actual hardware that turns biomass into biochar. Their equipment lines range from small batch reactors to continuous-feed systems capable of processing several tonnes of feedstock per hour.
Exomad Green, on the other hand, has positioned itself as a biochar-focused carbon removal company operating in Mongolia. The company has been building out its operations with an eye toward generating carbon removal credits, taking advantage of Mongolia’s abundant agricultural and forestry residues as feedstock. Mongolia’s geography and economy create a somewhat unique setup: there’s plenty of biomass waste, relatively low land costs, and a government that has shown interest in carbon market participation.
The “new phase” language suggests this isn’t a fresh relationship but rather an escalation of an existing one. Typically in these arrangements, the first phase involves equipment procurement and pilot operations, while subsequent phases focus on scaling production lines, optimizing throughput, and potentially co-developing customized reactor systems. The specifics of what this new phase entails in terms of tonnage targets or capital commitments weren’t fully detailed in the announcement, which is worth noting.
What This Changes
A few things stand out here.
First, the geographic axis. Most biochar carbon removal activity that gets attention in the voluntary carbon market is concentrated in Europe (think Stockholm Biochar, Carbofex) and North America (Pacific Biochar, Charm Industrial’s related work). The China-Mongolia corridor represents a different cost structure entirely. If Exomad Green can produce verified biochar-based carbon removal credits at significantly lower cost than European competitors, that changes the pricing dynamics for buyers. Whether Western credit buyers will be comfortable purchasing Mongolia-origin credits is a separate question, but the economic logic is compelling.
Second, the vertical integration angle. By partnering directly with an equipment manufacturer rather than buying off-the-shelf, Exomad Green potentially gets better pricing, priority on delivery timelines, and the ability to influence equipment design for their specific feedstock and operating conditions. Beston gets a committed customer and a foothold in the carbon removal credit market, which is a higher-margin application for their equipment than standard waste processing.
Third, this is another data point in the broader trend of biochar companies moving from “we have a single reactor” to “we’re building a production network.” The companies that will matter in biochar five years from now are the ones solving the scaling problem today, and scaling means securing reliable equipment supply chains.
Who Benefits
Credit buyers looking for lower-cost biochar removal credits could benefit if this partnership delivers real tonnage. Beston Group gets exposure to the voluntary carbon market’s growth trajectory without having to build a credits business themselves. Exomad Green gets the production capacity it needs to be taken seriously by large corporate buyers and intermediaries.
Mongolia itself could benefit from what amounts to a value-added processing industry for agricultural waste. Instead of burning crop residues in the field (a common practice that creates air quality problems), converting them to biochar creates a product with both carbon removal value and agricultural soil amendment benefits.
Caveats
The announcement is light on specifics. We don’t have tonnage targets, capital investment figures, or a timeline for when new production capacity comes online. “New partnership phase” can mean anything from “we signed an MOU” to “we’re commissioning new equipment next quarter.” Without those details, it’s hard to assess the actual near-term impact.
Verification and credit quality will be the real test. Biochar carbon removal credits need rigorous MRV (measurement, reporting, and verification) to command premium prices. The methodology matters: what feedstock is being used, what’s the carbon content and stability of the resulting biochar, how is it being applied or stored, and who is auditing the process? Exomad Green will need to demonstrate credibility on all of these fronts to attract buyers beyond the most price-sensitive segment of the market.
There’s also the geopolitical dimension. Western corporate buyers have become increasingly cautious about supply chain exposure to China, even indirectly. Whether a Mongolia-based operation using Chinese equipment faces any friction in voluntary carbon markets is an open question that could affect demand regardless of the quality of the underlying product.
Finally, biochar production is only half the equation. The other half is offtake: who’s buying the biochar, and at what price? Scaling production without secured demand creates its own risks. The carbon credit market for biochar removal is growing but still relatively thin compared to what large-scale production would require.
This partnership is worth watching as a signal of where biochar production might scale fastest and cheapest. But signals and tonnes are different things, and the sector needs the latter.
