The invention claimed is: 1. A cassette for a waste disposal device, the cassette comprising: an outer wall; an inner wall connected to the outer wall by a base; a flexible tubing positioned between the outer wall and the inner wall; and a rim having a top surface, a bottom surface and a circumferential edge, the rim being positioned between the outer wall and the inner wall, the rim extending from a top surface of the outer wall toward the inner wall forming a gap between the rim and the inner wall, the bottom surface of the rim facing the flexible tubing, the rim comprising a plurality of protrusions entirely on the top surface and on said circumferential edge of the rim, the plurality of protrusions commencing and extending entirely outward from the top surface of the rim. 2. The cassette of claim 1, wherein the cassette is cylindrical. 3. The cassette of claim 2, wherein the protrusions are radially spaced along the top surface of the rim. 4. The cassette of claim 1, wherein the protrusions can engage with a rotation mechanism of the waste disposal device. 5. The cassette of claim 4, wherein the rotation mechanism is an automatic rotation mechanism. 6. The cassette of claim 4, wherein the protrusions can engage with a gear surface of the rotation mechanism. 7. The cassette of claim 4, wherein the protrusions are ridges, and wherein each ridge can engage a corresponding notch of a notched bottom surface of the rotation mechanism. 8. The cassette of claim 1, wherein the plurality of protrusions extend from the circumferential edge toward the inner wall. 9. The cassette of claim 8, wherein the plurality of protrusions extend from the circumferential edge less than halfway to the inner wall on the top surface. 10. The cassette of claim 1, wherein the rim has a portion that extends from a top surface of the outer wall toward the inner wall and a connection portion that connects the rim to the outer wall, and wherein the connection portion extends downward from the portion that extends from a top surface of the outer wall toward the inner wall. 11. The cassette of claim 10, wherein the top surface of the outer wall has a projection that projects inward toward the inner wall, and wherein the connection portion of the rim has a side portion that is complementary in shape to the projection so that the projection of the outer wall contacts the connection portion. 12. A cassette for a waste disposal device, the cassette comprising: an outer wall having a top surface, a bottom surface, and two side surfaces; an inner wall connected to the outer wall by a base, the inner wall having a top surface, a bottom surface, and two side surfaces; flexible tubing positioned between the outer wall and the inner wall; and a rim having a top surface, a bottom surface, a circumferential edge, and two side surfaces positioned between the outer wall and the inner wall, the rim emanating from the top surface of the inner wall and extending partially towards the outer wall forming a gap between the rim and the outer wall, the bottom surface of the rim facing the flexible tubing, the rim having a plurality of protrusions entirely on the top surface and on the circumferential edge of the rim, the plurality of protrusions commencing and extending entirely outward from the top surface of the rim; wherein the cassette can engage with a rotation mechanism of the waste disposal device. 13. A cassette for a waste disposal device, the cassette comprising: an outer wall; an inner wall; a flexible tubing positioned between the outer wall and the inner wall; and a rim having a top surface and a bottom surface, the rim being positioned between the outer wall and the inner wall, the rim extending from a top surface of the outer wall toward the inner wall forming a gap between the rim and the inner wall, the bottom surface of the rim facing the flexible tubing, the rim comprising a plurality of protrusions on the top surface of the rim, the plurality of protrusions commencing and extending entirely outward from the top surface of the rim, wherein the rim has a portion that extends from a top surface of the outer wall toward the inner wall and a connection portion that connects the rim to the outer wall, wherein the connection portion extends downward from the portion that extends from a top surface of the outer wall toward the inner wall, wherein the top surface of the outer wall has a projection that projects inward toward the inner wall, and wherein the connection portion of the rim has a side portion that is complementary in shape to the projection so that the projection of the outer wall contacts the connection portion.
