3. 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 Observing existing systems and operations
o Interacting with the guests and staff
o Identifying possible new activities and system changes
o Piloting selected improvements

4. 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 Energy
o Water
o Transportation
o Waste
• Ultimate Goal becoming zero waste facility
o Entire facility introduced public composting in Spring 2010
o Switched majority of service ware to compostables
Compostable service ware examples, excluding gray decorative collector Blazers cup.

5. Current Systems and Conditions
• Three main areas of high public traffic and waste disposal
o 100 level
o 200 level (Club level)
 with restaurant style seating and serving staff
o 300 level
• 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

6. 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

7. Overview of Capstone Activities
• Observing Existing Systems &
Operations
o Identified waste reduction and recycling
efforts that would be beneficial for us to
focus on during the Trailblazers games
o 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

8. • 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

28. Concluding Remarks
We have a few simple, yet urgent, suggested
improvements to increase disposal accuracy
and total waste diversion rates.

29. • Passive Guest Opportunities:
o Improved containers signage
o Video messaging
o Compost table toppers
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
