Biofuels are fuels generated from biomass. Basic materials could be renewable vegetable substances, such as oil seeds, corn, etc., or animal fat   and oil waste. A liquid biofuel is the liquid part of these substances.

Low costs, highly attractive

The clear advantages of fuels derived from waste products are not only the low price, but they are also environmentally friendly. They are even CO2 neutral, generate considerably less particle emissions than HFO and emit practically no sulphates. This makes them a very attractive source of energy.

MAN Diesel & Turbo has had engines running on liquid biofuel since 1994. Our engines can burn a wide range of substances normally considered as waste. Vegetable oils, animal fats, used cooking oil, frying fat and tallow can also be used as fuel for our engines when pre-refined.

All of our MAN medium speed liquid fuel engines can burn liquid biofuels. And our medium speed dual fuel engines are naturally able to burn liquid biofuels in liquid fuel mode as well.*

*For MAN Diesel & Turbo to confirm if the engine can operate using a special type of fuel, please provide a detailed fuel specification.
