System and method for waste management

1. A method for waste management, comprising:

for each of a plurality of waste containers, recording a measurement of content within the respective waste container;

extracting a content parameter for the respective content from each measurement, wherein the content parameter comprises an optical property measurement for the content;

determining a volume parameter for the respective content from each measurement;

determining a purity index for a material category for each waste container, based on the respective content parameter;

selecting a subset of the plurality of waste containers for retrieval based on the respective material purity index and volume parameter; and

routing a waste removal vehicle to retrieve content from the selected subset of waste containers.

2. The method of claim 1 , wherein the measurement comprises an image.

3. The method of claim 1 , wherein the subset of the plurality of waste containers are selected in response to the respective volume parameters exceeding a threshold value.

4. The method of claim 1 , wherein routing the waste removal vehicle comprises selecting the subset of waste containers to obtain a threshold purity index for the totality of the content retrieved from the selected subset of waste containers.

5. The method of claim 1 , further comprising:

during content retrieval, recording a measurement of content within the waste removal vehicle;

extracting a content parameter for the content of the waste removal vehicle;

determining a purity index from the content parameter for the material category for the waste removal vehicle; and

comparing the purity index with a preliminary purity index, wherein the preliminary purity index is calculated from the respective purity indices of the waste containers from which content has been retrieved.

6. A method for waste management, comprising:

recording an image of content within a waste container at an optical sensor of the waste container, wherein the waste container is configured to contain waste material;

extracting a set of content parameters from the image at a processor of the container;

at the processor, calculating a purity index of the content within the waste container based on the set of content parameters;

estimating a time at which a content parameter of the set will exceed a threshold value; and

at a remote computing system in communication with the processor of the container, receiving the calculated purity index and, based on the estimated time, routing a waste removal vehicle to a location of the waste container based on the calculated purity index exceeding a predetermined purity index threshold.

7. The method of claim 6 , wherein the image is recorded in response to an occurrence of a trigger event.

8. The method of claim 7 , wherein the trigger event comprises ambient light exceeding a light threshold.

9. The method of claim 6 , wherein the image comprises a stereoscopic image.

10. The method of claim 6 , wherein the set of content parameters comprises brand names.

11. The method of claim 10 further comprising calculating the purity index based on packaging material information associated with the brand name.

12. The method of claim 6 , further comprising determining a fullness percentage, comprising a volume of content relative to a volume of the waste container.

13. The method of claim 12 , further comprising calculating a monetary value for the content based on the purity index of the content and the fullness percentage, and routing based on the calculated monetary value.

14. The method of claim 13 , wherein calculating the monetary value for the content comprises:

determining a material composition of the content based on the image; and

calculating the monetary value for the content based on market rates.

15. The method of claim 6 , further comprising repeating: recording an image of content within a waste container, extracting a set of content parameters from the image, and characterizing the content within the waste container based on the set of content parameters multiple times over a period of time.

16. The method of claim 6 , wherein the content parameter comprises a volume of content within the waste container.

17. The method of claim 13 , wherein routing the waste removal vehicle comprises routing the waste removal vehicle to maximize a monetary value of content retrieved by the waste removal vehicle.

18. A method for waste management, comprising:

for each of a plurality of waste containers, recording a measurement of content within the respective waste container;

extracting a content parameter for the respective content from each measurement;

determining a volume parameter for the respective content from each measurement;

determining a purity index for a material category for each waste container, based on the respective content parameter;

selecting a subset of the plurality of waste containers for retrieval based on the respective material purity index and volume parameter; and

routing a waste removal vehicle to retrieve content from the selected subset of waste containers, comprising selecting the subset of waste containers to obtain a threshold purity index for the totality of the content retrieved from the selected subset of waste containers.

19. The method of claim 18 , wherein the subset of the plurality of waste containers are selected in response to the respective volume parameters exceeding a threshold value.

20. The method of claim 18 , wherein the measurement comprises an image.
