But blending sewage with garbage accelerates the breakdown of the garbage. The result is steady supply of methane that can be used directly as fuel or mixed with natural gas for pipeline distribution. (Natural gas is mostly methane. The mix is relatively easy.)
There are more significant advantages blending the garbage and septage together and quickly reacting them into fuel:
--- Protect ground and surface water. The practice of spreading septic waste in open fields or pits could halt. Runoff and seepage of pathogenic biological agents from septic tank waste can contaminate ground water, surface water, rivers and streams. Septic tank waste pumped and sent to processing stations using a Septage Bioreactor would be converted to a usable fuel, not supposedly filtered out in the ground.
--- Extend landfill life. Landfills take up considerable acreage and fill up quickly with bulk garbage and trash. Converting that garbage quickly into fuel with the help of septage would eliminate bulk considerably. The less bulk, the longer the landfill will take to fill up.
