2. Upgraded Brown Coal || KOBE STEEL, LTD.

Prone to spontaneous combustion, brown coal is hardly ever used. On the other hand, because brown coal is noted for its low ash and sulfur, it has the advantage of being environment-friendly when burned. By removing the moisture, Kobe Steel's UBC Process raises the heat value, thereby converting brown coal into a high-grade energy resource.
