Recently I am interested in bioethanol. Bioethanol means, the ethanol which it is made from botanical resources,like sugar cane or corn .
Bioehanol is expected as the energy source, because it is renewable natural energy and don’t increase quantity of atmospheric carbon dioxide by combustion.
However it is point out as problem that a carbon dioxide reduction effect when look through the whole production process, effectiveness as the energy means of production and competition with the food.
Raw materials of the bioethanol are biological material containing carbohydrates.
Judging from production efficiency, it usually uses botanical resources containing a lot of glucide or starch. Therefore the following farm products are mainly used as raw materials. Sugar cone, cone and sugar beet and so on..
Bioethanol is almost used as fuel. Because it has following favorable characteristics as the fuel. In theory, it is inexhaustible energy because of made from renewable botanical resource. It don’t increase quantity of atmospheric carbon dioxide by the combustion
It is easy to mix with gasoline
In generally, when it mixes with gasoline, the fuel is indicated like this
Exx is show us that what percentage include in the mixed fuel.
For example E10 is included 10% biothanol. .In Japan, government is promoting to adopt E3 .In this year, as a first step, In 50 places of service station in metropolitan areas started to supply with E3.
Bioethanol has some merit. However it has demerit too. For example competition with the food, costs, is it really good for environment, and so on.
Now everyone do not clearly know, merit or demerit which is bigger for our life and environment. But I think that we should produce the bioethanol. Because it is good for environment to compared the fossil fuel and it is renewable natural energy.
