Former Oka and BeZero Carbon executives, Laura Fritsch and Ted Christie-Miller, have just announced the launch of Residual, a comprehensive solution for developing carbon removal projects.
The market opportunity they identified is rooted in the design of the projects. Ted Christie-Miller explains this by saying: “The future of carbon removal isn’t just about scaling—it’s about scaling right. Residual-grade design ensures that our project partners are building long-term assets, rather than long-term liabilities. By combining best-in-class design and risk mitigation, we can beckon in a new generation of top-tier, scalable carbon removal projects.”
The technologies Residual will kick off with revolve around biomass, like biochar and bio-energy with carbon capture. Christie-Miller explains that they have the highest potential to develop in the next five years.
Location is also important according to Oka’s former Chief Investment Officer Fritsch, who says that “Brazil offers an unparalleled opportunity for large-scale biomass-based carbon removal. With the world’s largest biomass reserves, a strong agricultural sector, and year-round crop production, it is uniquely positioned to scale durable carbon removals efficiently.”
Through collaborations with biogenic waste producers and emerging project developers, the new company is creating large-scale carbon removal initiatives and improving the quality of carbon credits.
With the carbon removal sector projected to experience significant growth in the coming decade, fueled by both voluntary and compliance-driven demand, Residual is positioning itself to be a leading provider of long-term carbon removal solutions by the 2030s, playing a pivotal role in fulfilling this increasing market demand.
Residual’s methodology goes beyond ensuring project feasibility, focusing on maximizing carbon credit ratings and minimizing insurance costs—key elements for attracting large-scale investments and building trust in the market.
The new company is also looking to bridge the gap between industrial players and project developers by becoming a partner with both. Its platform has developer and buyer sides and the team plans to work closely with both.


With industrials this will mean instructing them through multiple stages that begin with feasability assessment and credit generation to buildig up their confidence in methods that might be new to them. And when it comes to project developers this would cover services ranging from project design documentation, data monitoring and rating to insurance preparation and life cycle assessments.
The company has also appointed Mark Goldman as its Head of Science. Goldman, who has extensive experience leading scientific teams at Cloverly and Oneshot Earth, will contribute his expertise to Residual’s innovative approach.
