Mafix raises $5.4M pre-seed to demonstrate novel rock weathering process
What's the deal? Mafix has raised $5.4 million in pre-seed funding to scale a novel enhanced rock weathering (ERW) technique that boosts soil health while removing carbon dioxide.
What's the endgame? The money will help the company demonstrate and scale its process. ERW works by spreading crushed rock such as basalt across farmland, where it reacts with CO2 and locks the carbon away.
What could go wrong? ERW faces mounting scrutiny over how removals are measured. Some developers have called for a new way to quantify CO2 removal volumes, and project-level risks have emerged in early deployments because weathering materials must stay in place to count.
The signal: The round lands as carbon removal developers reassess their models. Some peers are pivoting away from carbon credits into adjacent markets, while European ERW firms are turning to industrial partnerships as the surest route to scale.
