@ www.nviro.com N-VIRO Fuel™ Combined with Gasification The synthetic gas exiting the gasifier contains smaller emissions of particulate matter. Waste heat can be used to provide heat to power process. Mix of volatile components in biosolids provides high combustion capability. End product is a sterile ash that is re-used . Lower temperatures needed therefore less heat input. Improved mass balance.
