Dirty Sewer Gas to Clean Fuel

Hydrogen sulfide is a gas that is emitted from sewer pipes that is toxic to humans, harmful to the environment, and corrodes pipes. The SULGEN Process is able to fix the problem of hydrogen sulfide cheaply. It uses inexpensive materials such as iron sulfide to turn the hydrogen sulfide into hydrogen fuel, which can be used as an alternative to oil and gas.
