「サステオ」Euglena’s biofuel “SUSTEO”




The fuel that can be purchased at gas stations in general towns is made from petroleum excavated from the ground. The carbon dioxide emitted when burned is based on the carbon that originally slept deep in the ground, and the carbon dioxide in the atmosphere increases unilaterally.

On the other hand, biofuels are produced from terrestrial biological resources (biomass raw materials) such as plants and animals. Biological resources absorb carbon dioxide in the atmosphere in advance by photosynthesis in the growth process and ecosystem. Therefore, the carbon dioxide emitted when burning biofuel is simply restored from what was previously taken in from the atmosphere.
Biofuel is a sustainable fuel that is being developed with the concept of not increasing the amount of carbon dioxide in the atmosphere.

What is biofuel made of?

There are many types of biological resources (biomass raw materials) that are the raw materials for biofuels, and with the evolution of biofuels, the raw materials have also changed. The first raw material was edible plants such as sugar cane and corn. However, there were problems such as competition with food and deforestation due to unreasonable cultivation. Waste-based raw materials such as used cooking oil are now the mainstream raw materials that do not cause these problems. Demand continues to rise year by year because it is possible to reuse what should have been thrown away and it has a high CO2 reduction effect.
As the demand for biofuels increases in the future, it is necessary to promote technological development to secure sustainable raw materials so as not to cause problems due to raw material shortages.





Renewable Diesel Fuel (RDF)

SUSTEO 's diesel fuel is used in land and sea mobility such as buses and ships.
The characteristic of "next generation biofuel" is that its molecular structure is exactly the same as that of commercially available diesel fuel. Therefore, the results of the exhaust gas test confirm that it can be used with a content rate of 100% without imposing a load on the engine of a general vehicle.
In addition, SUSTEO 's diesel fuel can be used as it is for cars running in the city, and unlike fuel cell vehicles such as electricity and hydrogen, there is no need to develop a new supply infrastructure. Thus, it has the advantage of being easy to adapt to daily life.
