Overview
•Why IPR?•Benefits of RFID•Challenges facing RFID•Experiments
Why are we pushing for IPR?
•EPR does not truly encourage better design – Black Box Payment
•If Producer is only responsible for own waste – More incentive
•Reduce Environmental impact through reuse
Benefits of RFID
•Product linked to database with info on how to dismantle
•Info on location of hazardous materials
•Advantages on selecting most appropriate EOL option
Challenges facing RFID
•Past Experiments showed overall read rate of 30%
•High metal content in mixed WEEE causes issues for tags
Antenna DetunedLoss of signal strength
Experiments•Lab experiment to test tags•Field Experiments Experimental setup for white
goods Mixed WEEE
RFID System
•Tag : Size, type, read distance, orientation sensitivity
•Reader: Type(handheld), reader orientation, read time, power
•Environment: cage type, number of contents, temperature etc..
Lab Experiment•Distinguish most suitable Tags
•Read Distance and Orientation Sensitivity
•2 substances used – Steel and plastic
Results of Lab experiment
Setup for white goods
•Stacked neatly in 20-40 foot container
•Read distance restricted by container•Washing Machines, dryers, refrigerators etc...
Results of White goods
•100% Readability was achieved on 25 items in 20 foot container
•This would be target in an ideal system
•Attributed to bulk of goods and uniform stacking method.
Mixed WEEE Setup
•Stored in metal cages•No structure to stacking•Amount of products varies•78 tagged appliances tagged with the 3 different tags used
Results from mixed WEEE
Conclusion
•Results support that RFID can be used to support IPR
•Real world application with white goods still at concept level
•Research to improve RFIDs could lead to higher Read percentage in mixed WEE
