1/3 of eligible material
Existing Recycling Programs:
 Single Stream
 Pay as You Throw (PAYT)

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.

System Overview
 Benefits to:
Collection Agencies
Consumer
Municipalities
2.0
Design Objectives
 Guidelines in which the project must
adhere to properly fit the specifications.
 Accuracy
 Usability
 Adaptability
2.1
Design Objectives
 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.
2.2
Design Objectives
 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.
2.3
Design Objectives
 Adaptability
 RFID Tagged Receptacles: The ability to reuse 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.

Runs Mobile Control program
Windows CE
Program written in C#
Microsoft SQL Server
32MB of Flash memory
Headless
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
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
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)
4.1 Assumptions and
Limitations
 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 postferrous seperation. But, has not yet been
implemented in the Recycle Nation program.

Cost
 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.
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
 Load Cell and RFID Software are also operational
8.0
Future Options
 Dynamic Web Upload
 Data Mining
 Eddy Current – Aluminum
Seperation
 More Robust web interface
with different levels of
control
