The system and method for recycling and using the heat from compressed gas produced by a biogas treatment plant. The system includes a biogas cleaning stage and a plurality of compression and heat exchanger stages that allows the heat generated by compressed gases to be harvested. After the heat is harvested, it is delivered to a jacketed vessel containing media used to remove contaminants from the biogas. The media inside the jacketed vessel requires regeneration or stripping of harmful VOCs and other contaminants picked up from the biogas. The system also includes an inert gas generator that creates hot inert gas that is delivered to the jacketed vessel that heats the media located therein to remove contaminants. Because the jacket vessel and the media are simultaneously heated, the system's heat-up time is reduced The system also includes a heat exchanger that partially recovers the heat from the inert gas.
