Wurster Hall = 225,000 square feet College of Environmental Design University of California, Berkeley

Departments of: Architecture, Landscape Architecture and Environmental Planning, City and Regional Planning, CED Library, Fabrication Shop, Ceramics Studio, Ramona’s CafÊ, Research Units, faculty and staff offices, instructional space 7 Design Studios, mostly Architecture, with 24/7 occupancy Average daily occupancy of over 1,000 people, mostly students


University of California, Berkeley

Design Studio at the end of the Semester Mixed materials: Plastics, cardboard, foamcore, paper, models

Total Estimated Weight of Materials Cleaned Out: 7,000lbs


University of California, Berkeley

Same Design Studio after clean up 9 Student working 4 full days to clean 6 Design Studios Waste Separation = Lots of Work Hours

Getting to Zero Waste: Waste Audit Team University of California, Berkeley

The Waste Audit Team is funded by a grant from The Green Initiative Fund. It consists of 5 UC Berkeley students dedicated to decreasing the amount of waste produced by the UC Berkeley Campus.


The Waste Audit Process University of California, Berkeley

• We collect the landfill waste from buildings and bring it back to the office to sort. • We sort into six categories: Cardboard; Mixed Paper; Metal and Glass; Landfill; All Plastics; and Compost

Wurster Hall: Waste Management and Compost University of California, Berkeley

• • • • • •

Waste Issues Food Service waste from Café Materials used for making Design Models High 24/7 Occupancy Reduced level of Custodial Service since 2009 No Weekend Custodial Service


Old Waste System University of California, Berkeley

   

Old Waste Habits are hard to break Easy to put everything in one place Huge Opening Had been throughout building, removed over 30 Some conflict when they were replaced


CED Waste Management Initiatives University of California, Berkeley

• Bottle & Can recycling in Lobbies • Building compost started in 2010 • Day Custodian hired; takes out compost waste: night custodians currently do not service compost • Studio Re-Stations built for Design Studios • Waste Separation in Studio Clean Out • Collaborated with Campus Recycling and Refuse Servicesto develop standard campus waste signage


Studio Materials Re-Use Stations University of California, Berkeley


Student Group Initiatives University of California, Berkeley

• Groups such as Compost Alliance have helped remove trash cans and communicate about compost • Student initiated custodial poster project being continued


Campus Initiatives and Waste Diversion Status University of California, Berkeley

• Campus Recycling and Refuse Services implemented standardized campus signage • Housing and Dining uses compostable containers, provides compost service • Excellent construction waste diversion • 2012 Waste Diversion Goal = 75% • 2012 Waste Diversion Actual = 46%


The Green Initiative Fund Grant Wurster Hall Zero Waste Pilot Project University of California, Berkeley

• College of Environmental Design students advocated for new building waste containers • Grant proposal submitted to TGIF for new public area waste containers • TGIF awards grant based upon whole building Zero Waste pilot waste containers • Forms and Surfaces for 5 public lobbies (Medium Volume -24 gallon) • Max-R for 1st Floor Lobby and 7 Design Studios (High Volume - 48 Gallon)

New System (5/2013)


New System Objectives: Waste Separation & Increased Efficiency University of California, Berkeley

• Consistent Container type, Signage, Color • Reduced opening makes people separate waste • Centralized set of containers instead multiple containers going down corridor • Increased waste collection efficiency and ease of collection for custodians • Improved container aesthetic


Audit Specifics • University of California, Berkeley

Audit was of 3 days of waste • Sorted only from landfill • 6 major categories • Waste sorted from two 2yd3 dumpsters and varying numbers and sizes of toters.


How Big is 2yd3?

University of California, Berkeley

You can fit over 80 standard office waste bins in one 2yd3 dumpster

Mid-Implementation Audit University of California, Berkeley

After the original audit was conducted, new containers were installed throughout the building in phases The mid-implementation audit evaluated changes in waste separation and diversion

All Plastics Landfill Compost Totals

• Better Plastic Diversion • Less Waste Overall


Areas of Improvement University of California, Berkeley

• Enclose Odor • Compost < 24 Hours = Stinky • Students in the LAEP studio removed the compost container and covered up the opening. We made lids in the Shop.


Container Aesthetic University of California, Berkeley

• This is the Design School! • Top of header board does not line up with concrete wall behind it • Dean did not like big plastic box in entry lobby • Solution is to clad waste cabinet with nicer looking material/Flat headerboard


Lessons Learned University of California, Berkeley

• Open Compost Container in Closed Space will Smell • Aesthetic matters in high visibility space • Sorting waste takes time • Compost is a major component of the waste stream • Five is the magic number of people


Next Steps University of California, Berkeley

â&#x20AC;˘ Custodial Services will start composting paper towels in restrooms â&#x20AC;˘ Post-Implementation Waste Audit in October 2013
