There is few way to treat waste food that increasing in these days and future. We will do not have place even to bury that at close future. So I study to treat this. In high temperature from 50 to 80 °c, anaerobic situation, I bring my micro cell up that is take waste food apart and make methane gas which we can use. First step, I input waste food to tank that exist micro cells high loaded. Virus destroyed in this step cause high temperature that can make faster fermentation treatment. And then, I get useful methane gas and little volume of waste which more safe from virus. It can be adapted to any country waste food by waste food components research and I believe the best way to treat that.
