Turn anaerobic digestion biogas into a cost effective, green vehicle fuel. When activated sludge from a POTW-WWTP is kept in an anaerobic environment, specialized bacteria develop that use the excess sludge as a source of organic matter for anaerobic digestion, a series of processes in which microorganisms break down biodegradable material in the absence of oxygen.

Coal mine methane is released from the coal and surrounding rocks by mining. In underground mines, it can create an explosive hazard to coal miners, so it is removed through ventilation and degasification systems. In abandoned mines and surface mines, methane might also escape to the atmosphere through natural fissures.
