About
MacroCarbon SL is a Las Palmas (Gran Canaria) startup spun out of Germany’s Alfred Wegener Institute and US-based Carbonwave in March 2023, backed by SPRIND Carbon-to-Value funding. The company intercepts free-floating pelagic Sargassum macroalgae in the open Atlantic and processes the biomass through a thermal biorefinery (screw press, pyrolysis to biochar, methane pyrolysis) to produce bio-stimulants, carbon-negative sustainable aviation fuel (BlueSAF Plus), and durable biochar for carbon sequestration.
