A waste disposal apparatus having outwardly-canted sidewalls and a base wall forming a basin. A liner is centrally disposed on an interior of the basin. At least one litter sieve is centrally arranged on the liner. A securing flange is located on a top portion of the sidewalls and is operable between a closed position and an open position and includes at least one handle protrusion. The litter sieves and the liner are held securely in place by the securing flange when the securing flange is in the closed position. A litter sieve can include opposing handle ribbons removably disposed in corresponding envelopes on opposite sides of the sieve. The envelopes can include frangible elements that selectively secure the handle ribbons, but that fail upon application of a force so that the ribbons can at least partially exit the envelopes and thereafter used to lift a loaded sieve.

1. A waste disposal apparatus comprising: four outwardly-canted sidewalls and a base wall forming a basin;at least one liner centrally disposed on an interior of the basin;a plurality of litter sieves centrally arranged adjacent the at least one liner; andsecuring flanges, each securing flange adjacent a top portion of one of the sidewalls, the securing flanges being operable between a closed position and an open position and each including at least one securing flange finger tab,wherein the plurality of litter sieves and the at least one liner are held securely in place by the securing flanges when the securing flanges are in the closed position,wherein at least one of the sidewalls includes a sidewall handle protrusion,wherein each securing flange is hingedly joined with the top portion of the respective sidewall,wherein the finger tabs are substantially centered between distal ends of the securing flanges and configured to assist a user in pivoting the securing flanges between the open and closed positions. 2. The apparatus of claim 1, wherein each of the sidewalls includes a female receiving member. 3. The apparatus of claim 2, wherein each of the securing flanges includes a male engagement tab. 4. The apparatus of claim 3, wherein when the securing flanges are in the closed position, the male engagement tabs engage the female receiving members so as to secure the securing flanges in the closed position. 5. The apparatus of claim 1, wherein the securing flanges each include a top plate joined with an engagement flange,wherein the engagement flanges directly engage one of the plurality of sieves,wherein the engagement flanges move relative to the top plate when the engagement flanges secure the plurality of sieves and at least one liner between the engagement flanges and the respective sidewalls. 6. The apparatus of claim 1, wherein each securing flange includes a flex element adapted to enable an engagement flange to flex and move when the engagement flange engages at least one of the plurality of sieves. 7. The waste disposal apparatus of claim 1 wherein each sidewall includes an upper ledge and each securing flange is joined to the respective upper ledge adjacent an outer perimeter of the upper ledge such that the securing flange pivots outward, away from the interior of the basin. 8. The waste disposal apparatus of claim 7 wherein the plurality of litter sieves are disposed adjacent the sidewalls and are arranged such that the plurality of litter sieves do not extend onto the upper ledge of the sidewalls. 9. A waste disposal apparatus comprising: four outwardly-canted sidewalls and a base wall forming a basin having an interior;at least one liner centrally disposed on the interior;a plurality of litter sieves centrally arranged on the at least one liner; andsecuring flanges, each securing flange adjacent a top portion of one of the sidewalls, the securing flanges being operable between a closed position and an open position, each securing flange including a finger tab substantially centered between distal ends of the securing flange and configured to assist a user in pivoting the securing flange between the open and closed positions,wherein the plurality of litter sieves and the at least one liner are held securely in place by the securing flanges when the securing flanges are in the closed position,wherein each of the plurality of litter sieves include a plurality of pass-through holes,wherein the securing flanges are hingedly joined with the top portion of respective sidewalls and each includes a flex element that selectively flexes to enable the securing flange to close to the closed position regardless of whether the at least one liner only is disposed in the basin, or whether the at least one liner plus the plurality of litter sieves are disposed in the basin,wherein each securing flange includes an engagement flange that engages and clamps the plurality of sieves between the engagement flange and the sidewalls to hold up the plurality of sieves along the sidewalls. 10. The apparatus of claim 9, wherein the sidewalls include a female engagement tab,wherein the securing flanges include a male engagement tab,wherein when each securing flange is in the closed position, the male engagement tab is in engagement with the female engagement tab to secure the securing flange in the closed position. 11. The apparatus of claim 9, wherein each securing flange includes a top plate,wherein each finger tab defines an opening sized to accommodate at least two human fingers, the finger tab projecting upwardly from the top plate,wherein the securing flange is hingedly secured to an upper ledge of the respective sidewall. 12. The apparatus of claim 9, wherein the engagement flange includes an engagement tip that engages at least one of the plurality of sieves and the at least one liner,wherein the engagement tip is disposed at a first distance from the sidewall when the at least one liner and the plurality of sieves are disposed between the engagement tip and the sidewall,wherein the engagement tip is disposed at a second distance from the sidewall when only the at least one liner is disposed between the engagement tip and the sidewall,wherein the second distance is less than the first distance. 13. The waste disposal apparatus of claim 9 wherein each of the sidewalls includes an upper ledge and each securing flange is joined to the respective upper ledge adjacent an outer perimeter of the upper ledge such that the securing flange pivots outward, away from the interior of the basin. 14. The waste disposal apparatus of claim 13 wherein the plurality of litter sieves are disposed adjacent the sidewalls and are arranged such that the plurality of litter sieves do not extend onto the upper ledge of the sidewalls. 15. A waste disposal apparatus comprising: four outwardly-canted sidewalls and a base wall forming a basin;a liner removably disposed in an interior of the basin;a plurality of litter sieves removably arranged adjacent the liner;securing flanges, each securing flange hingedly joined with a top portion of one of the sidewalls, the securing flanges operable between a closed position and an open position, the securing flanges each including a finger tab substantially centered between distal ends of the securing flange and configured to assist a user in pivoting the securing flanges between the opened and closed positions; andat least one pair of sidewall handle protrusions disposed on opposite ones of the sidewalls and configured to enable a user to lift the basin,wherein the plurality of litter sieves and the liner are held securely in place by the securing flanges when the securing flanges are in the closed position. 16. The waste disposal apparatus of claim 15 including recessed corners disposed between adjacent ones of the sidewalls at an upper end of the sidewalls. 17. The waste disposal apparatus of claim 16 wherein the sidewall handle protrusions define recesses on the interior of the basin. 18. The waste disposal apparatus of claim 17 wherein the recessed corners and the handle recesses on the interior of the basin are configured to nest with one or more waste disposal apparatuses in a stacked configuration. 19. The waste disposal apparatus of claim 15 wherein each sidewall includes an upper ledge having an outer perimeter, wherein each securing flange is joined to the respective upper ledge adjacent the outer perimeter such that the securing flange pivots outward. 20. The waste disposal apparatus of claim 19 wherein the plurality of litter sieves are disposed adjacent the sidewalls and are arranged such that the plurality of litter sieves do not extend onto the upper ledge of the sidewalls.
