A method of injecting steam into a landfill is provided. The steam enhances methane gas production in the landfill during the anaerobic phase, accelerates decomposition/biodegradation of the organic component of the trash prism during both the aerobic and anaerobic phases, and increases the rate of settlement of the landfill. A method of introducing a gaseous anaerobic fertilizer into the landfill is also provided. The fertilizer accelerates the decomposition/biodegradation of the organic component of the trash prism. A method of reducing the volume of a plastic component of the trash prism is provided, wherein the temperature and pressure of injected steam are raised to a level sufficient to melt plastic. Finally, a method of reducing the volume of a quantity of refuse prior to placing the refuse in a landfill is provided, wherein the refuse is heated to melt a plastic component of the refuse.

1. A method of enhancing methane gas production in a landfill having a trash prism, accelerating decomposition/biodegradation of an organic component of the trash prism, and increasing a rate of settlement of the landfill, comprising the steps of:providing at least one steam injection well and at least one gas extraction collector; providing a source of steam; injecting the steam into the trash prism via the steam injection well; and extracting methane gas produced by decomposition/biodegradation of organic refuse within the trash prism via the gas extraction collector.
