An exemplary embodiment is comprised of dual opposing augers that are adapted to grab, compress, and shred the material, reducing the material size such that it may be discharged through a side outlet opening and/or an extrusion tube into, for example, a standard roll-off compaction container. An exemplary embodiment allows large material to be processed in a low speed device with reduced equipment dimensions, providing operator safety with low profile loading, lower noise level, reduced chances of material being expelled from the processing chamber, and ability to use conventional material transport (e.g., semi-trucks). ## Claims ### Claim 1 A system for shredding, comprising: a

respectively comprised of a tapered shaft and a tapered flight. ### Claim 8 (depends on 1) The system of claim 1 wherein each of said first tapered auger and said second tapered auger is respectively comprised of a flight having at least one tooth that extends from an edge of said flight. ### Claim 9 (depends on 1) The system of claim 1 wherein each of said first tapered auger and said second tapered auger is respectively comprised of a shaft such that said shafts are substantially parallel. ### Claim 10 (depends on 1) The system of claim 1 wherein said top of said processing chamber is configured to be 7.5 feet or less above ground or floor level. ### Claim 11 (depends on 1) The system of claim 1 wherein at least one of a respective rate and a respective direction of rotation of said first tapered auger and said second tapered auger is configured to be adjusted. ### Claim 12 (depends on 11) The system of claim 11 wherein each of said first tapered auger and said second tapered auger is configured to be adjusted with respect to said respective rate and said respective direction of rotation. ### Claim 13 (depends on 11) The system of claim 11 wherein said first tapered auger and said second tapered auger are configured to be independently adjusted with respect to at least one of said respective rate and said respective direction of rotation. ### Claim 14 (depends on 13) The system of claim 13 wherein each of said first tapered auger and said second tapered auger is configured to be independently adjusted with respect to said respective rate and said respective direction of rotation. ### Claim 15 (depends on 1) The system of claim 1 wherein at least one of said first tapered auger and said second tapered auger is configured to change direction of rotation. ### Claim 16 (depends on 1) The system of claim 1 wherein said first tapered auger is configured to rotate at a faster rate than said second tapered auger to facilitate discharge of said shredded material through said side discharge opening. ### Claim 17 (depends on 1) The system of claim 1 wherein each of said first tapered auger and said second tapered auger is configured to
