A global tech giant has commissioned an industry-wide data call through Supercritical, looking to hear from biochar developers, feedstock owners, and operators as part of an effort to determine what biochar needs to reach gigatonne-scale carbon removal.
The data call covers four biomass feedstock categories: large-scale forestry residues, nut and fruit shells, rice husk and straw, and sewage sludge.
“The biochar market doesn’t have a science problem. It has a supply problem,” said Michelle You, CEO of Supercritical.
“The published literature only tells you about the projects that worked. Nobody has mapped where feedstock actually sits at volume, what it costs, and why projects stall, and that’s the evidence a serious buyer needs before committing capital. This research builds it.”
Open to a range of different biochar entities, the call is designed for project developers, independent experts, feedstock owners and processors, including rice mills, sawmills, nut processors, and wastewater operators.
Biochar has surfaced as the most in-demand carbon dioxide removal (CDR) pathway on the market, delivering more permanent CO2 removal today than any other method.
This approach tackles different types of waste biomass, converting it into a CO2-dense biochar product through a pyrolysis process. With the built-up demand momentum over the past few years, the main obstacle for scaling biochar further is not carbon science but feedstock availability.

The purpose of the Supercritical biochar data call
Through this data call, Supercritical intends to canvass the supply end of biochar in order to evaluate whether biomass exists at volume, at a workable cost, and in the right places.
The call was commissioned by one of the world’s largest tech companies, and it will feed a research program that will conclude with recommendations on where capital, offtake support, research funding, and policy engagement can unlock supply.
Responses will be used in an aggregated or anonymized form, and Supercritical will also be shortlisting respondents for follow-up interviews.
Submissions will be accepted by 7 August 2026, and interested parties can submit responses via this form.
