Abstract
The present invention relates generally to the production of energy and the reclaimation of carpet waste material. More particularly, the invention relates to a method and system for storing and using post industrial and post consumer carpet as fuel in an energy generation process and for producing at least one recyclable carpet waste material.
Claims31
A method for energy production, comprising:
- providing a carpet waste composition, the carpet waste composition comprising an inorganic filler component and a first organic component;
- mechanically treating the carpet waste composition such that at least a portion of the first organic component of the carpet waste composition is separated from the carpet waste composition;
- producing a first combustible stream comprising the at least a portion of the first organic component of the carpet waste composition;
- from the carpet waste composition, producing a first waste stream comprising a reclaimed inorganic filler composition that is substantially free of the organic component of the carpet waste composition;
- delivering the first waste stream to a first waste storage unit;
- selectively delivering the first combustible stream to a boiler;
- and
- directly combusting the first combustible stream within the boiler.

- selectively delivering the first combustible stream to a boiler;
- and
- directly combusting the first combustible stream within the boiler,
- wherein the step of selectively delivering the first combustible stream to the boiler comprises selectively delivering the first combustible stream to a grate section of the boiler, the grate section having a plurality of stepped grates that are configured to burn the first combustible stream, wherein at least every other grate of the plurality of stepped grates is configured to articulate in a reciprocating motion to affect the sequential downward tumbling of the first combustible stream as it is burned and consumed.
