Non-Reusable Water Bottles
• 60 million bottles are discarded daily • in the UK, half billion bottles are shipped in
for use annually• could be filled 1/4 with oil to show footprint• 1 in 6 bottles make it to recycling• 51 billion bottles in the US alone• 17 million barrels of oil• enough oil to run 1 million cars for a year• 1 in 6 bottles are recycles - the rest end in
landfill• $22 billion industry in the Unites States
annually

Parallel Campus Initiatives
• Vassar College: campus-wide plastic water bottles ban
• Harvard University | School of Public Health: bans sale of bottles, reduces plastic bottles in waste stream by 1000 units/wk
• U. of California at Berkley: campus student store bans bottles water sale
• College of St. Benedict, St. Paul, MN: 31 hydration stations developed campus wide attracts media attention by USA Today

Parallel Projects at Duke
Marine Lab at Beaufort: eliminates al single-use plastic beverage bottles in all of its campus on the NC coast
This project includes Dining Operations, Catering, and all vending services on the Piver’s Island Campus
Hopes of bringing same goals to Duke’s Durham Campus

Plant-Based Bottles
Can be derived from multiple origin plants
Lauded as an ‘eco-friendly’ alternative to PET (standard plastic)
Cannot be recycled by Duke’s contacted waste management recycler: Sonoco Recycling
Major brands: PepsiCo and Coca Cola have competing branded bottles of plant-based of biodegradable plastic bottles designed for landfill disposal
Monday, April 16, 12
Alternatives to PET Plastic (Team B)
• Analyzed various bio-plastics as an alternative to PET in single-use water bottles
• Utilized a Life Cycle Analysis method of research
• CHALLENGES:
• Incongruence with Duke Climate Action Plan
• Waste processor backlash
• Unfeasibility of implementation
Monday, April 16, 12
Recycling Bottles at Duke
• Sonoco: only accepts PET-based bottles for recycling at facilities
• Can recycle plastics #1 through #7 - all are PET-based
• Several on-campus vendors sell plant-based or ‘green’ bottles, which are visually indistinguishable from PET relatives
• Students appear to use recycling receptacles only if they are conveniently located

Duke Community Input
• Online survey targeting graduate/undergraduate population of Duke
• n=78 (55 men, 23 women)
• Duke students:
• Support increasing use of reusable water containers
• Demonstrate substantial opportunities for improvement
• Dislike inconvenience of filling, which prevents students from carrying reusable bottles

Data Analysis
• Most students (+80%) responded that the reason they don’t carry a bottle:
• inconvenience of carrying a reusable bottle
• inconvenience of refilling a bottle

• Randy Orange• DSG Student Environment and Sustainability
Committee• George Carotenuto• Kerri Devine
• East Campus Council (ECC)• LB Bergene
• Nicholas Institute for Environmental Policy Solutions

East Campus Model
• First iteration of proof-of-concept: Hydration Station Implementation
• One hydration station in each East Campus dorm (in addition to Marketplace, Brodie Gym, and Carr Building locations)
• Would foster a more sustainable-thinking class, from first semester at Duke
• East Campus Council supports project
Monday, April 16, 12
Orientation Water Bottles
• Currently, reusable water bottles are distributed to Duke First-Years during Orientation programming
• Bottle’s size raises several concerns about purpose and usefulness
• GOAL: to work with the Nicholas Institute and Student Wellness Center to use Nicholas Institute funding to provide larger water bottles with better highlighted purpose
• Currently, Duke Student Wellness supports the small size bottle

Hydration Stations on West
• Project refocused for long-term inclusion in new building design
• Randy Orange: no control over East renovations; it became apparent that the East Campus Model would not work for current campus design
Monday, April 16, 12
Challenges
• Jim Wilkerson, Director of Trademark Licensing
• Duke University Stores
• Joe Clark, Residence Hall Operations
• East Campus Installation plan
• Funding
• “Green Grants” already used
• DSG reelection

Where we stand:
• Administrative Suddport:• East Campus Council• Facilities Management Team
• DSG Funding• Confident about units to be built on West Campus• Appropriations for next year necessary
• West Campus Installation• Identifying high traffic areas• Budget reviews in July 2012, facilities hopeful for hydration station
inclusion
Monday, April 16, 12
Moving Forward
1.Install stations in Wilson Gym and Bryan Center
2.Coordinate with Nicholas Institute and Student Wellness to redesign bottles for First-Year Orientation
3.Appropriate funding for more units next year, especially alongside the July 2012 budget review
4.DSG Legislation for New Building, maintain relationship with SESC
5.Cultivate first-year students’ ‘social responsibility’ ethos
