World’s First HPPO Method
Capitalizing on its thirty years of technology, SKC is striving to produce better quality PO in a more eco-friendly way. Our microbe treatment facility established in the mid-2000s has drastically reduced pollutant emission by treating waste liquid from production with bacteria. In 2008, we lunched the first HPPO method in the world, which generates no waste water with the use of peroxide.
