"School lunch garbage" ="Biotechnology ethanol"+"Biogas +".Tokyo Gas Co., Ltd. executes the experiment.

A concrete content of the experiment is as follows. The school lunch garbage etc. of elementary and junior high schools in Koto Ward chiefly crush the garbage 200 kilos/a day in constructed facilities, and saccharify the enzyme in addition. Because the carbohydrate in garbage changes into sugar in this, it divides into the liquid and solid squeezing it, the liquid is fermented, and the biotechnology ethanol is collected. A remaining solid etc. collect biogas. In short, the biotechnology ethanol and biogas can be refined from the school lunch garbage etc.

Biotechnology ethanol and simultaneous collection system of biogas from garbage

The made ethanol is allotted to the operation of the equipment in facilities by using educational and the biogas of the school with power generation and the boiler because the refinement scale is small in the proof experiment facilities now. It is said that a concrete amount of the refinement will aim at the ethanol of biotechnology each day 5 liters (90% or more in the density) and 20 cubic meters of the methane. Moreover, it is said that it is assumed that it can visit facilities, and promotes the environmental problems enlightenment to the local populace and the contribution to environmental education.

In environmental education, a big effect can be expected that it explains the mechanism of the recycling site of the resource showing the equipment that is actually the operation. It is because "Feeling of the site" that doesn't understand not substituted easily for anything is confirmed by my eyes in sentences and photographs. The effect of the plus is done and is sure to wither in Mitibi for environmental problems as the age is passed though might be not effective of the immediate effect in other educational facilities and similar techniques.

Moreover, it is likely to become the foothold of construction in real facilities of making to the business if the problem that turns out in the process of the proof experiment is investigated thoroughly and it gropes for the improvement. I want to expect it of the development in the future.
