1. An Environmental Improvement Program For Incentive Based Recycling The Trash Masters Zach Leatherman Travis Stubbendeck Tom Yarmer

2. Contents 1 System Overview 2 Design Objectives 3 Technical Overview 4 Assumptions and Limitations 5 Testing 6 Cost 7 Status 8 Future Options

3. 1.0 System Overview  139 Million Americans  50% Take Advantage  1/3 of eligible material  Existing Recycling Programs:  Single Stream  Pay as You Throw (PAYT)

4. 1.1 System Overview ConsumerRecyclables RFID Tagged Bin Preliminary Sort Collection Vehicle Weigh Material Determine Value Return Incentive $$$

5. 1.2 System Overview  Four Specific Modules  ID Module: Receptacle identification  Sort Module: Preliminary sorting of materials  Weight Module: weigh sorted material  Comm. Module: software and hardware for communication and storage of data, including the web site.

6. 1.3 System Overview  Benefits to: Consumer Collection Agencies Municipalities

7. 2.0 Design Objectives  Guidelines in which the project must adhere to properly fit the specifications.  Accuracy  Usability  Adaptability

8.  Accuracy  RFID: Tags must be read accurately to properly identify each consumer.  Conveyor Belt: Must have a high level of accuracy to ensure the weights of various materials for proper incentive.  Weight Sensor: Needs to be precise so that a proper amount of money is refunded to each consumer. 2.1 Design Objectives

9.  Usability  Weight Sensor Automation: The sensor are automatically monitored so that the data is logged without the collection agent being required to interact with it.  Wireless Transfer: The Ebox automatically upload all of the collected data to the central server. 2.2 Design Objectives

10.  Adaptability  RFID Tagged Receptacles: The ability to re- use existing curbside receptacles by just placing an RFID tag on them.  Web Interface: Customer web interface can easily be changed to each company’s needs.  Collection Vehicles: Existing collection vehicles to be outfitted with a conveyor belt. 2.3 Design Objectives

11. 3.0 Technical Overview Overview

12. Conveyor Belt  Small work of art  Neoprene 10 inches wide  4, 3inch diameter PVC pipes  1/15 horsepower motor  Geared slower  Magnetic Head Pulley

13. Magnetic Head Pulley Ferrous Material Non-Ferrous Material Legend

14. RFID Reader  PCProx from RFIdeas  Connected to EBox through USB  1 to 3 inch range  LED mounted on top to ensure tag is read every time  Trash Receptacles could be designed to ensure tag is read

15. Mobile Unit / EBox  Runs Mobile Control program  Windows CE  Program written in C#  Microsoft SQL Server  32MB of Flash memory  Headless

16. HandyBoard  6811 Microcontroller system  Used for analog to 8-bit digital conversion  Runs simple program that continuously reads weight from 2 load cells  Outputs through RS232 Serial port

17. Central Server  Receives data from EBox through 802.11G Wireless signal  Microsoft Windows XP  Microsoft SQL Server Express  Apache Server  Runs web interface and billing system

18. 4.0 Assumptions and Limitations  Small Scale  Conveyor belt 1/3 width as in collection vehicle  Magnets could be bigger or stronger for better seperation.  RFID Reader  Could be at 100% accuracy with controlled lifting mechanism from the collection vehicle (assuming lifting mechanism comes standard with vehicle)

19.  Cost  The cost might not be viewed as worthwhile without government or city subsidizing our recycling efforts.  This argument remains valid due to energy saved from recycling vs. making new material  Aluminum  Eddy currents: This process may be utilized post- ferrous seperation. But, has not yet been implemented in the Recycle Nation program. 4.1 Assumptions and Limitations

20. 5.0 Separation Testing B. Chicken of the Sea ( 0.8 oz ) A. Clam Chowder ( 2.8 oz ) D, E. Dog Food ( 1.6 oz ) C. Generic ( 1.2 oz ) A BCDE

21. 5.1 Separation Testing Results Possible Outcomes := {Hit, ½ Hit, Miss} Horizontal Test Vertical Test

22. 5.3 Separation Testing Tweaks  Placement of Bins  Separator to act as crutch for ferrous material  Conveyor Operation Speed: 11 – 12 inches per second

23. 6.0 Cost  Wood Supplies for Conveyor Frame$37.41  Conveyor Belting and Lacing$60.72  Miscellaneous Conveyor Supplies$70  Magnets$48.25  Load Cells (x2)$110  RFID Readers $189  20 RFID Tags$59  Wireless Bridge for EBox$79.99  Domain Name (recyclenation.org)$9.95  Total$664.32

24.  Conveyor Belt  Price of fabricating a stand for the belt would not be valid due to placing it inside of the conveyor belt.  RFID Tags  Much cheaper if bought in bulk  Reader, Load Cells, and Magnets  Prices would stay relatively the same. 6.1 Cost

25. 7.0 Status  ID Module:  The RFID reader correctly reads and accurately reports tag identification numbers.  Sort Module:  Conveyor belt seperates ferrous from non-ferrous materials.  Weight Module:  Load cells being run from a HandyBoard and attached to the two containers on the belt.  Comm. Module:  Website: http://www.recyclenation.org http://www.recyclenation.org  Load Cell and RFID Software are also operational

26. 8.0 Future Options  Dynamic Web Upload  Data Mining  Eddy Current – Aluminum Seperation  More Robust web interface with different levels of control
