ユーグレナ社のバイオ燃料
「サステオ」Euglena’s biofuel “SUSTEO”

ユーグレナ社のバイオ燃料
「サステオ」

化石燃料に代わる、サステナブルな社会を実現するための燃料、それが「サステオ」です。
2020年に次世代バイオディーゼル燃料を、2021年はバイオジェット燃料を供給開始し、車両・船舶・航空機で利用が拡大しています。

「サステオ」=サステナブルな燃料=バイオ燃料

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.

持続可能な原料とは?

バイオ燃料「サステオ」の原料は、食糧との競合や森林破壊につながることのない、サステナブルなバイオマス原料です。当社はそのなかから、コストや供給量の観点を踏まえて原料を選択しています。現在は、主に使用済みの食用油を利用しています。

使用済みの食用油は現在世界中で使用されている原料である一方、有限な資源のため、将来的にバイオ燃料の需要が増えた際、足りなくなってしまう日がくると予測されています。

そこでユーグレナ社は、食料と競合せず、また、必要量に合わせて供給することができる原料として、ユーグレナ油脂培養の技術開発にも注力しています。

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. 

「サステオ」の活用事例

「サステオ」ロゴに込められた想い

サステオは、多くの方にバイオ燃料を身近に感じていただくため命名されました。サステオは、「サステナブルなオイル」が由来となっています。
文字部分ではサステオを力強く広げていくという意思と地球へのやさしさを表現。そして、“多様性”を意味する最小単位の3種の大きさからなる「サステオ・ドット」は、サステオがさまざまな用途で、自由に使用される様や、サステオが広がることによって、地球の負担が軽減され、地球が緑色を取り戻していく様をデザインで表現しています。この「サステオ・ドット」は「カーボンニュートラル」の実践の象徴であり、世界の環境問題を解決するという、ユーグレナ社の願いと決意を表しています。
