Our biofuel "SUSTEO"

Euglena's biofuel "SUSTEO"

Our biofuel

"SUSTEO" is a fuel that replaces fossil fuels and is used to realize a sustainable society.
Next-generation biodiesel fuel will be supplied in 2020, and biojet fuel will be supplied in 2021.
Its use is expanding in vehicles, ships, and aircraft.

"SUSTEO" = Sustainable fuel = Biofuel

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.

Raw materials for Susteo, what are used cooking oil and the microalgae Euglena?

The raw materials for SUSTEO are used cooking oil and Euglena oil and fat extracted from the microalgae Euglena.
The proportion of used cooking oil is 90% or more, and the ratio of Euglena oil is 10% or less.
While spent cooking oil is a raw material currently used around the world, it is a finite resource, and it is predicted that there will be a day when the demand for biofuels will increase in the future.
Euglena is also focusing on the technological development of Euglena oil and fat culture as a raw material that does not compete with food and can be supplied according to the required amount.

Sustainable Aviation Fuel (SAF)

SUSTEO 's jet fuel is a Sustainable Aviation Fuel (SAF) that complies with the international standard "ASTM D7566 Annex 6 Standard".
Our biofuel production demonstration plant uses biofuel isoconversion process technology and is the first Sustainable Aviation Fuel in the world to meet ASTM certification. SUSTEO 's jet fuel can be mixed with existing petroleum-based jet fuel by up to 50%.

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. 

Susteo "Susteo" logo

SUSTEO was named to make biofuels more accessible to many people. SUSTEO is derived from "sustainable oil".

In the character part, it expresses the intention to expand SUSTEO powerfully and the kindness to the earth. And, "SUSTEO Dot", which consists of three sizes of the smallest unit that means "diversity", is a burden on the earth due to the free use of SUSTEO for various purposes and the spread of SUSTEO. Is reduced, and the design expresses how the earth regains its green color. This "SUSTEO Dot" is a symbol of the practice of "carbon neutral" and represents Our desire and determination to solve the world's environmental problems.
