The most honest measure of a climate business is what it does with a pile of waste. For Biochar Industrial Group, the answer is to park a pyrolysis unit next to it, turn the heat up past 600 degrees Celsius, and sell the resulting carbon removal. The Nigerian startup, founded in 2026, is betting that the path to industrial-scale carbon removal in Africa runs directly through the backlots of its food processing plants [Perplexity Sonar Pro Brief, September 2026].
The Factory-Floor Wedge
BIG’s model is simple in concept but complex in execution. It partners with food processors that generate low- or negative-value agricultural waste,think palm kernel shells, nut husks, and corn cobs,and installs continuous pyrolysis equipment directly at their facilities [Perplexity Sonar Pro Brief, September 2026]. The company then finances, installs, operates, and staffs the hardware. Its service handles the entire chain: converting waste to biochar, managing the carbon measurement and verification, and selling the resulting removal credits [Perplexity Sonar Pro Brief, September 2026]. For the factory owner, it’s a new revenue line and a solution to a logistics headache. For BIG, it’s a Biochar-as-a-Service contract that turns a cost center into an asset.
The initial commercial deployment, announced in July 2026, was with Releaf Earth, a Y Combinator-backed agro-processing company in Nigeria. BIG served as the technical partner, converting Releaf’s palm-kernel-shell waste into biochar [carbon.fyi, July 2026]. It’s a telling first customer, and not just because of the shared history.
A Team Built on Industrial Trust
The three co-founders,CEO Ikenna Nzewi, CTO Uzoma Ayogu, and COO Isaiah Udotong,are not new to building physical infrastructure in African agriculture. They spent nearly a decade together at Releaf Earth, where they built industrial processing plants and supply chains [BusinessDay, October 2026]. That track record of delivering hardware in complex environments is likely what convinced a specific set of investors to back their new venture.

In September 2026, BIG closed a $1.5 million pre-seed round. The lead was BREEGA, with participation from The Catalyst Fund; The Mulago Foundation provided non-dilutive funding [BusinessDay, October 2026]. The capital is earmarked for deploying more equipment, expanding across Sub-Saharan Africa, and hiring in engineering, operations, and carbon verification [TechCabal, September 2026].
The Unit Economics of Removal
The financial mechanics here are everything. BIG’s model must cover the capital cost of the pyrolysis unit, its operation and maintenance, the rigorous verification of carbon sequestration, and still turn a profit from credit sales. The company hasn’t disclosed its credit pricing or the volume of carbon removed per ton of waste, but the back-of-the-envelope math points to the challenge. If a mid-sized palm oil mill produces 1,000 tons of shell waste annually, and pyrolysis converts roughly a third of that mass into stable carbon, you’re looking at sequestering a few hundred tons of CO2 per site per year. At current voluntary market prices for high-quality biochar credits, that’s a revenue stream in the low hundreds of thousands of dollars annually, per site. The bet is that at scale, across dozens of sites, the unit economics and the value of the carbon asset outweigh the logistical complexity.
The Incumbent Is Inaction
The most direct competitor BIG faces isn’t another pyrolysis startup. It’s the status quo: waste being burned openly, landfilled, or left to decompose, which releases carbon back into the atmosphere. For a food processor, dealing with waste is a cost. BIG’s job is to prove that its service is not just carbon-negative but also operationally simpler and financially additive compared to existing disposal methods. The company must beat the inertia of the existing waste-handling contract.
The Next Twelve Months
The immediate roadmap is about proving the model can replicate. With the pre-seed capital, BIG will need to move beyond the pilot with Releaf Earth and secure contracts with two or three new, unaffiliated food processors. The key signals to watch will be new deployment announcements and, crucially, a disclosed partnership with a carbon credit registry or a corporate buyer for the offsets. Success in the next year looks like a small cluster of operating units, each quietly turning agricultural byproducts into a permanent carbon sink and a new line on a factory’s income statement.
