Background
• PSU Solid Waste Reduction and Recycling Capstone
- Fall 2010
• Partnering with the Rose Garden Arena and its
contracted food services vendor, Ovations
• Goal of improving recycling and composting by guests
in the largest public areas of the Rose Garden during
Portland Trailblazers basketball games
• Pursued that goal through hands on work in the facility
o
o
o
o
Observing existing systems and operations
Interacting with the guests and staff
Identifying possible new activities and system changes
Piloting selected improvements
Current Systems and Conditions
• LEED Gold certification of arena in Spring 2010
o
First sports venue in the U.S to be awarded this recognition
• Dedication aimed towards:
o
o
o
o
Energy
Water
Transportation
Waste
• Ultimate Goal becoming zero waste facility
o
o
Entire facility introduced public composting in Spring 2010
Switched majority of service ware to compostables
Compostable service ware examples, excluding gray decorative collector Blazers cup.
Current Systems and Conditions
• Three main areas of high public traffic and waste disposal
100 level
200 level (Club level)
 with restaurant style seating and serving staff
o 300 level
o
o
• Guests dispose waste into newly designed and introduced
four part containers
• Majority of waste being generated:
 Compostable:
 Food
 Food containers
 Drink cups
 Landfill:
 Many candy wrappers
 Various printed handouts
 Snow cones and cotton candy
Overview of Capstone Activities
• Teamed up with the Rose Garden to interface with
Trailblazer fans about waste reduction and recycling,
observe the facility's existing systems and make
suggested improvements
Overview of Capstone Activities
• Observing Existing Systems &
Operations
o
o
Identified waste reduction and recycling
efforts that would be beneficial for us to
focus on during the Trailblazers games
Each game we performed different
activities
 Recycling and composting education
to guests
 Interacting with guests & employees
throughout facility
 Data collection about disposal in four
part containers
Overview of Capstone Activities
• Identified new physical system changes:
o Removal of "old" recycling and trash areas
o Repositioning containers during different parts of the
game
o New signage for public containers
• Developed activities that would fit in well with the current
atmosphere of the Rose Garden to help increase
awareness about the facility’s recycling and composting
programs

Thursdays: Sign Comparison
• Among the mistakes made during Thursday games, the
majority of the mistakes were compostables going into
landfill bin
• Percentage of mistakes decreased after adapting new
signs
• However, 24% of the mistakes went into bins with new
signs (from 11/18/2010)

Saturdays: Signs Comparison
• Accuracy of disposal choice improved after adapting new signs
• 51% of the mistakes made on 11/20 went into bins with new
signs, while both were monitored
• Major problem of compostables going into landfill container
improved after introducing the new signs

Possible Errors in the Data Analysis
• Bias due to the structure of the data collection
process
• Irregularities due to coding errors
• Some portions of the collected data were not
included in this analysis due to coding errors
and incorrect coding
Concluding Remarks
We have a few simple, yet urgent, suggested
improvements to increase disposal accuracy
and total waste diversion rates.
Suggested Improvements
based on Capstone Activities:
• Passive Guest Opportunities:
o Improved containers signage
o Video messaging

o Point of sale composting advertisements
o Composting program information on tickets
and literature
• Benefits of This Approach:
o Major focus on new compostable products
that are most confusing for public
o Minimal staff and resources needed after
implementation
o Full facility coverage
We Compost!
