Sewage Sludge Solid Fuel System ”J-COMBI™”

J-COMBITM converts sewage sludge, which has conventionally been disposed of through landfilling or incineration, into a solid fuel that can be used as an alternative to coal through a granulation and drying process.

Moving from "treatment" to "resource recovery," J-COMBITM contributes to reducing CO2 emissions through the effective use of sewage sludge-derived fuel.
