SCHOOL COMPOSTING LOGISTICS, BUY-IN AND LESSONS LEARNED
AGENDA • FOOD… FOOD… MORE FOOD… • SKCOR
• DIY – HOW TO APPLY OUR LEARNING CURVE TO YOUR SCHOOL
THE PROBLEM: 30,000 MEALS WEEKLY .25 POUNDS/MEAL/PERSON WASTED 150 TONS OF WASTE EACH YEAR >50% IS FOOD WASTE/RESIDUALS
37+ TONS OF PRE-PLATE “VEGAN” FOOD RESIDUALS EACH YEAR
COLLECTED BY DINING SERVICES
HAULED BY RECYCLING STUDENT WORKERS
COMPOSTED ON SITE BY GROUNDS CREW
LANDFILL 150 TONS EACH YEAR
WASTE AUDIT RESULTS: DINING COMMONS WASTE IS COMPOSED MOSTLY OF FOOD RESIDUALS (BY WEIGHT)
ADDED FOOD STATION BINS TO CAPTURE MORE MATERIALS
ADDRESSED FOOD WASTE IN THE KITCHENS
DONATIONS?
WANT TO CAPTURE VEGAN FOOD RESIDUALS FOR CAMPUS USE
WOULD LIKE TO DIVERT MOST OF THE FOOD RESIDUALS SENT TO LANDFILL
ANALYSIS SUMMARY STEPS
RESULTS
• Worked with Dining Services to identify weak areas
• Provided additional bins at each food station
• Better data tracking • Pushed dialogue between Dining Services and local food kitchens • Waste Audit
• Increased educational outreach to kitchen staff • Immediate feedback loops • Successfully reduced dining hall waste by 100 tons over 3 years
SKCOR: PILOT PROGRAM SODEXO IS KEENE ON COMPOSTING ORGANICS AND RECYCLING
STAKEHOLDERS EMPOWERMENT!
RESEARCH: DATA ANALYSIS • HOW MUCH WASTE?
• HOW FREQUENTLY IS COMPACTOR EMPTIED? • COSTS? • HOW COLLECTED? • WHO INVOLVED? • TYPES OF MATERIAL? FOOD AUDIT
NEW DATA MINIMIZE WASTES REDUCE CONTAMINANTS
CONTAINERS (TYPE AND SIZE)
SEVERAL MONTHS LATER…
JULY 2012: PILOT PHASE 1 • ARRANGED HAULER/HAULING SCHEDULE (CONTRACT)
• RETROFITTED SELF-CONTAINED COMPACTOR • PURCHASED 23 GALLON YELLOW CONTAINERS • PURCHASED 3 STREAM STATION BINS • REMOVED POSSIBLE CONTAMINANTS FROM WASTE STREAM • EDUCATIONAL OUTREACH
SUCCESSES • CAPTURED OVER 8 TONS IN A 6 – 7 WEEK TRIAL (SUMMER!)
• BACK OF HOUSE COMPLIANCE AND ENGAGEMENT
• POTENTIAL DIVERSION OF APPROXIMATELY 90 TONS!
• INCREASED RECYCLING AWARENESS (ASSUMED PARTICIPATION)
LEARNING MOMENTS • SEALED COMPACTOR AND CONTAINERS • PICK-UP SCHEDULE AND RESPONSE TIME
• MOISTURE (ADD WAXED CARDBOARD?) • CARBON SOURCES?
• ERGONOMIC ISSUES • CHAIN OF COMMAND (LOGISTICS PLANNING) • BARREL WASHING • “CLEAN TRASH” CONTAMINATED WITH FOOD WASTE
SKCOR PHASE 2: NEXT STEPS • PURCHASE CART TIPPER • FINALIZE BARREL WASHING ROOM • RE-TRAIN/EDUCATE • NEW CONTAINERS (SEALED COMPACTOR AND SEALED TOTERS)
STAKEHOLDERS STILL ENGAGED!
WHAT ABOUT YOU? HOW CAN YOU APPLY OUR PILOT PROGRAM TO YOUR SCHOOL?
SIMILAR PROCESS • COLLECT AND ANALYZE DATA • HOW MUCH PRODUCED? • WHERE/WHAT?
• EVALUATE CURRENT PROGRAM
• LOGISTICS • EXPLORE OPTIONS • CONTAINER SIZE/SHAPE? • WHO/HOW LIFT? • BAG OR NO BAG? • WHERE WILL IT GO?
• IDENTIFY STAKEHOLDERS
• WHO WILL COLLECT IT?
• IDENTIFY POSSIBLE HAULERS AND FACILITIES
• WHO WILL HAUL IT?
IF AT FIRST YOU DO NOT SUCCEED… …TRY, TRY AGAIN!
