The shipping industry is under increasing pressure to reduce its carbon footprint while maintaining efficiency and reliability. MASH Makes has developed an advanced biofuel derived from agricultural waste that could offer a sustainable solution. A recent whitepaper by FVTR GmbH confirms that this biofuel meets critical performance and emissions standards for marine engines, reinforcing its potential as a drop-in alternative to fossil fuels.

What is MASH Makes biofuel?

MASH Makes’ biofuel is a second-generation fuel produced through pyrolysisPyrolysis is a thermochemical process that converts waste biomass into bio-char, bio-oil, and pyro-gas. It offers significant advantages in waste valorization, turning low-value materials into economically valuable resources. Its versatility allows for tailored products based on operational conditions, presenting itself as a cost-effective and efficient More, a process that heats cashew shell residues without oxygen to create three key products:

• Biofuel – A liquid fuel compatible with marine diesel.
• BiocharBiochar is a carbon-rich material created from biomass decomposition in low-oxygen conditions. It has important applications in environmental remediation, soil improvement, agriculture, carbon sequestration, energy storage, and sustainable materials, promoting efficiency and reducing waste in various contexts while addressing climate change challenges. More – A carbon-rich byproduct that enhances soil quality and sequesters carbon.
• Pyrolysis gas – A fuel that helps power the production process.

This biofuel offers over 90% lifecycle CO₂ reduction compared to conventional marine fuels, making it a promising solution for decarbonizing the shipping industry.

Performance and emissions testing

FVTR GmbH conducted rigorous testing to evaluate the biofuel’s operational feasibility and environmental impact.

• Engine compatibility: A 20% biofuel blend (B20) was tested on a single-cylinder research engine. Results showed smooth combustion with no major deposits on engine components, even under high-temperature and high-pressure conditions.
• Emissions control: NOx emissions were slightly higher due to the oxygen content in the biofuel but remained within IMO Tier II limits. Carbon monoxide levels remained stable, indicating efficient combustion.
• Maintenance and cleanliness: Unlike many biofuels, MASH Makes biofuel did not form sludge when mixed with water, simplifying fuel handling and reducing maintenance issues. Engine injectors showed minimal wear or deposits after testing.
• Fuel efficiency: The calorific value of the biofuel closely matched traditional marine fuels, ensuring comparable energy output and operational performance.

Key takeaways

MASH Makes biofuel can be used in existing marine fuel systems without requiring major modifications. With over 90% CO₂ reduction, this fuel provides a practical way for the shipping industry to lower emissions while repurposing agricultural waste. Testing confirmed stable engine performance, consistent power generation, and no significant operational issues.

Following the successful lab and engine tests, the next phase involves trials on a live vessel to assess real-world performance. This will be a crucial step toward commercial adoption and wider implementation in the marine sector.
