Science Japanese scientists turn dung into rocket fuel

Air Water has been manufacturing liquid biomethane in Hokkaido since 2021. It ferments the dung and urine in a plant constructed on a dairy farm in the town of Taiki before transporting the generated biogas to a factory in Obihiro. The methane is then separated from the product, cooled and made into liquid biomethane. Rockets require liquid fuel to generate enough power to blast off into space. While high-purity methane is usually manufactured using liquid natural gas, the company has been working on creating methane of a similar quality through waste-sourced biogas. Interstellar Technologies will conduct tests to confirm the fuel created from cow waste can be used for its devices and aims to utilize it for its Zero rocket with a small satellite payload.
