Advanced biomass conversion

We’re developing a next-generation gasifier to convert agricultural residues into clean energy and biochar using diverse feedstocks. This is what will take us from megaton carbon removal to true gigaton potential.

Pushing the limits of renewable energy tech

At MASH Makes, our current platform turns cashew press cake—a niche agricultural residue—into biofuel and biochar. With this, we’re already running full-scale production and could scale to 50–100 similar sites.

But we’re not stopping there.

We’re now stepping into thermal gasification, a major leap in our technology roadmap. Unlike pyrolysis, which requires consistent input types, thermal gasification accepts a wide range of biomass—from sugarcane waste to sewage sludge—and always delivers the same high-value output: a clean syngas blend of hydrogen, CO₂, CO and nitrogen. This opens the door to producing advanced energy commodities at scale, while still generating high-grade biochar for carbon removal and soil health.

With this shift, we’re building toward tens of thousands of decentralised energy sites—designed to run on the world’s most abundant, underused residues. The result is a uniquely cost-effective and reliable way to pursue synthesis pathways like methanol, diesel, and hydrogen without locking into a single fuel strategy.

Biomass gasification meets stable CDR

Unlike conventional systems, MASH Makes’ gasifier combines biochar-based carbon removal, renewable syngas production, and modular deployment in a single, scalable unit.

The entire system fits within a standard shipping container, making it fast to deploy and easy to relocate based on biomass availability. It accepts a wide range of agricultural residues — from cashew shells to rice husks — and produces both energy and stable carbon storage without relying on rare catalysts or fossil infrastructure.  

Heat is recovered and reused, increasing overall efficiency, while the char-bed acts as an in-situ catalytic filter to enhance gas quality and reduce emissions. This integration of decentralised biofuel production with carbon dioxide removal makes the gasifier a uniquely circular, carbon-negative solution for today’s energy and climate challenges.
