Abstract

Systems and methods for determining a relative quantity of recyclable items, wherein the calculation is determined based on a total number of items. In one embodiment of the present invention, a computer-implemented method includes reading an identifier respectively associated with at least some of a total number of items. The computer determines a number of identifiers associated with the recyclable items. The computer also receives the total number of items, and computes the relative quantity of recyclable items by dividing the number of identifiers associated with the recyclable items by the total number of items.

Claims

1. A computer-implemented method for determining a relative weight of recyclable items with respect to a weight of a total number of items, comprising:

reading an identifier respectively associated with at least some of the total number of items;

determining by the computer a number of identifiers associated with the recyclable items;

determining by the computer a total weight of the recyclable items by multiplying the number of identifiers associated with the recyclable items by the weight of each recyclable item;

receiving a weight of the total number of items; and

computing the relative weight by dividing the total weight of the recyclable items by the weight of the total number of items.

2. The computer-implemented of claim 1, further comprising removing at least a portion of the total number of items when the relative weight is less than a predetermined weight.

3. The computer-implemented method of claim 1, wherein the identifiers comprise radio frequency identifier tags.

4. The computer-implemented of claim 3, further comprising removing at least a portion of the total number of items when the relative weight is less than a predetermined weight.

5. The computer-implemented method of claim 1, further comprising the computer accessing a data repository to determine a weight of the recyclable items.

6. The computer-implemented method of claim 5, further comprising generating an alert if an identifier is associated with a banned waste item.

7. The computer-implemented method of claim 1, further comprising generating an alert if an identifier is associated with a banned waste item.

8. The computer-implement method of claim 1, wherein computing the relative weight is done regularly.

9. The computer-implemented method of claim 1, further comprising sorting the total number of items, wherein the sorting is adjusted based on the computed relative weight of the recyclable items.

10. A computer-implemented system for determining a relative weight of recyclable items with respect to a total number of items, comprising:

a reader for reading an identifier respectively associated with at least some of the total number of items;

a scale for determining a weight of the total number of items; and

a computer that computes the relative weight of recyclable items by;

determining a first weight by multiplying the number of identifiers associated with the recyclable items by the weight of each recyclable item; and

dividing the first weight by the weight of the total number of items.

11. The computer-implemented system of claim 10, wherein the identifiers comprise radio frequency identification tags.

12. The computer-implemented system of claim 11, further comprising a data repository storing an identifier associated with the recyclable items.
