Waste handling method
First Claim
1. A method of handling waste, comprising:
- a) providing transport means having a material-receiving cavity and a waste-receiving bladder carried within a portion of the cavity;
b) loading a flowable waste material into the bladder at a waste collection site;
c) transporting the waste material to a treatment facility, the treatment facility being located remotely of the collection site;
d) unloading the waste material from the bladder and delivering the waste to the treatment facility;
e) filling a portion of the material-receiving cavity of the transport means with a non-waste material;
f) transporting the non-waste material to a drop-off site located remotely of the treatment facility; and
g) anaerobically digesting the waste at the treatment facility to produce a biogas containing carbon dioxide, separating the biogas into a relatively carbon dioxide-rich gas and a relatively carbon dioxide-poor gas and utilizing the carbon dioxide-rich gas to enhance the growth of vegetation.

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.
