The United States is facing a garbage crisis. Several areas of the country have already run out of landfill space, and recent studies indicate that many other areas will be experiencing the same problem with the next ten years. Institute of Gas Technology (IGT) has patented an advanced biogasification technology called LANFILGAS that accelerates the stabilization of landfills through anaerobic composting and recovers the methane gas for its energy value. Anaerobic composting, or digestion, is a natural process that takes place in every landfill. It is generally uncontrolled, however, and can take up to 30 years to stabilize a landfill.
