MASH Makes and global shipping company DS NORDEN have successfully completed the first commercial vessel trial using a carbon-negative biofuel.
The vessel, on a roundtrip from Singapore to Brazil, used 65 tons of a blended fuel that included 20% MASH Makes biofuel in its auxiliary engine.
MASH Makes CEO Jakob Bejbro Andersen commented: “Our biofuel meets the technical requirements of the shipping industry and can be used in unmodified engines. It’s a seamless, scalable alternative ready to cut emissions today.”
The trial confirmed the fuel’s compatibility with existing ship systems, offering a practical, immediate solution for reducing emissions — especially as the International Maritime Organization considers a global carbon pricing framework set to take effect in 2028.
If adopted in 2025, shipowners using MASH biofuel could gain a head start on compliance. MASH Makes biofuel is produced through pyrolysis, converting agricultural waste into renewable energy and biochar.
Unlike green hydrogen or ammonia, it requires no new infrastructure and meets ISO8217 marine fuel standards.

For every ton of biofuel produced, 1.8 metric tons of biochar are also generated — sequestering up to 5.7 tons of CO2 permanently in soil. Following successful use in auxiliary engines, trials in main engines are planned to broaden adoption across commercial fleets.
MASH Makes is also working with the Maersk Mc-Kinney Møller Center for Zero Carbon Shipping to assess full lifecycle emissions and validate the climate impact of its biofuel and biochar.
MASH Makes’ facility in Karnataka, India, currently processes 23,700 metric tons of agricultural waste per year, yielding 3,400 tons of bio-oil.
A second plant under construction will triple capacity, contributing to the company’s goal of removing over one gigaton of CO2 by 2040.
