MASH Makes Advanced Biofuel

The drop-in solution for decarbonising hard-to-abate industries.

Revolutionary biofuel for a low-carbon future

94% Carbon
reduction

Cuts the carbon footprint of conventional marine fuels by up to 94%, according to an ISCC audit.

Proven
Compatibility

Used in a full-scale vessel trial with DS NORDEN — showing stable, reliable performance in unmodified engines.

Innovative and
cost-effective

Made from agricultural residues, our fuel supports existing infrastructure and reduces costs — with no rare or expensive catalysts.

Benefit-boosting
biochar

The same process produces biochar — a by-product that enhances soil and sequesters carbon permanently.

Empowering the
Global South

We produce close to biomass sources, building local value chains in regions like India and expanding into Vietnam.

Future-Ready
Technology

Our next-gen gasification platform will support cheaper production of biogenic hydrogen and CO₂.

World’s first vessel trial with carbon-negative biofuel

MASH Makes and DS NORDEN have completed a world-first commercial shipping trial using biofuel made through a carbon-negative process.
The 65-tonne fuel blend, including 20% MASH biofuel, powered a roundtrip voyage from Singapore to Brazil — demonstrating compatibility with marine engines and delivering real-world performance.

Harnessing thermochemical innovation

MASH Makes biofuel is produced using pyrolysis — a thermochemical process that converts agricultural waste into energy products without oxygen. This yields:

Biofuel

Drop-in replacement for fossil marine
fuels, proven at sea

Biochar

Applied to soil to enhance fertility
and permanently store carbon

"               

Our independent analysis shows that MASH Makes’ biofuel production process is carbon negative, which is driven by the permanent
carbon sequestration achieved through the co-produced biochar and its use in sustainable agriculture.

Where can you use MASH Makes
Advanced Biofuel?

For marine use

Successfully used in auxiliary engines during the DS NORDEN vessel trial. Compatible with VLSFO and MGO. No retrofit required.

For boiler use

Used reliably in marine boilers and industrial furnaces. Tested with Alfa Laval burners and compliant with ISO8217:2005, BS 2869:2010, ASTM D396-18a, and more.

For use with high flash
point fuels (ISO8217)

Proven in engine-equivalent tests with ISO8217-compatible fuels. Stable across varying loads and pressures.

For blending
with methanol

Works as a combustion enhancer in methanol blends like B23 and B58. Improves ignition properties, lubricity, and heat release.

Not CNSL. Not the same problems.

While our feedstock includes cashew press cake — a by-product of cashew nut processing — it’s not Cashew Nut Shell Liquid (CNSL).
Our fuel is chemically distinct, corrosion-free, and proven in marine engines. It has a higher cetane number, doesn’t emulsify with water, and shows no corrosive effects — addressing key issues seen in CNSL-based fuels.

Technical specifications

Calorific Value

41 MJ/kg — higher than many other
bio-based fuels

Feedstock

Diverse agricultural residues, including cashew press cake

Co-Products

Biochar and syngas — supporting sustainability and carbon removal

Engine Compatibility

Comparable to ISO8217 fuels; tested with VLSFO and MGO

Cost-Effectiveness

Lower production costs with no reliance on rare catalysts

Trial Verified

DS NORDEN vessel trial confirmed real-world performance

Sustainability beyond fuel

Every tonne of MASH Makes biofuel also yields 1.8 tonnes of biochar, sequestering 5.7 tonnes of CO₂ in total. This carbon-negative process is independently assessed by Boundless Impact and will soon be validated under third-party certification schemes.

We're also working with the Maersk Mc-Kinney Møller Center for Zero Carbon Shipping to validate our full emissions profile using advanced lifecycle methodology.

Partnering for impact

FAQs about MASH Makes biofuel

How does MASH Makes biofuel compare to other sustainable fuels?

Our biofuel offers a higher calorific value and lower production costs compared to other bio-based and electricity-based sustainable fuels. It also integrates seamlessly with existing infrastructure, while at the same time offering benefits in terms of e.g. ignition properties for methanol.

Is MASH Makes biofuel compatible with existing shipping engines?

Our biofuel is designed as a drop-in solution, meaning it is designed to work with current engines and supply chains without requiring any modifications. A vessel trial with global shipping company NORDEN is planned to verify its use and efficacy.

Where does the biomass for your biofuel come from?

We source biomass residues from agricultural by-products, primarily from the cashew value chain in India, with plans to expand our sourcing to other regions.

Can MASH Makes biofuel be used in other industries beyond shipping?

Our current focus is on shipping and heavy industry, where demand for sustainable, high-quality fuels is highest. However, the versatility of our technology allows for potential expansion into other sectors.

What are the next steps for MASH Makes biofuel?

We are preparing for a vessel trial with DS NORDEN, which will be a crucial step towards the commercialisation of our biofuel. Additionally, we are working on expanding production and refining our technology for even greater efficiency and scalability.
