The enormous amount of petroleum we use daily threatens not only depletion of fossil fuel resources but also the very future of environmental conservation.
As early as the 1990s, Sangi began research on the synthesis of biogasoline using hydroxyapatite. Sangi’s scientists developed a technology to produce butanol and other industrial chemicals from biomass-derived ethanol using a hydroxyapatite catalyst, aiming to help reduce dependence on petroleum-based fuels. Bioethanol obtained by fermenting the inedible parts of sugarcane and corn was brought into contact with HAP catalysts and successfully synthesized an alternative to gasoline.

Sangi has registered patents for catalytic functions not found in other catalysts, thanks to its ability to control the properties of its hydroxyapatite. Sharp increases in the price of bio-ethanol worldwide, plus the emergence of shale gas, cast a shadow on the feasibility of alternative technologies. However, looking to the future, Sangi hopes to continue to contribute to the realization of a sustainable, low-carbon society through its proprietary technology.
