technology and business model
Every day, about 10 tons of waste food is generated in the production of cut vegetables, which poses a problem in terms of waste treatment.
The food residue is used to generate flammable digestive gas in a fermenter, and the generated biogas is used as fuel to operate a biogas micro-cogeneration system to generate electricity and heat.
The generated electricity is sold under the feed-in tariff system, and the heat is used for heating the fermenter, so that biogas can be used without waste.
In addition, the amount of waste after fermentation is reduced to about 1/10 of the amount before fermentation, and a method of utilizing it as fertilizer is also being studied.(During verification)
In addition, the system has been introduced at food processing factories and food waste treatment plants near Osaka.
