Abstract
The present invention provides a method of handling waste. In one embodiment, the invention provides a method for economically transporting waste from one location to another, treating the waste to produce a biogas, and utilizing a portion of that biogas to enhance plant growth and/or as a fuel source. In another embodiment, the method involves loading waste into the a waste-carrying vessel and transported to a remote treatment facility, where it is unloaded. The waste is then anaerobically digested at the treatment facility and a portion of the biogas resulting from the anaerobic digestion is utilized to enhance the growth of vegetation. The portion of the biogas so used is desirably relatively rich in carbon dioxide. The remaining portion of the biogas, which is desirably relatively rich in methane, and relatively carbon dioxide-poor, may then be combusted as a fuel source.
