Open market hauling system
WLSSD Organics Program: basic facts
MN State capital grant for siteconstruction
Opened September 2001
Compost source-separated organicsand yard waste
MPCA Permit: 3950 tons yard waste+ 3950 tons food waste/year
Garden Green® Compost (USCC/STA)production: 2500 yds/year
Nine years of growth and change (2001-2010)
Voluntary organics recovery program for businesses &institutions (2001 – 2006)• 30-50 regular participants• 1 hauler• Organics acquisition contractor (part-time)
Residential curbside pilot (2003)
Stakeholder meetings: haulers & generators (2004)
Established food waste drop sites for residents and smallbusiness use (2004-2009) Seven sites in operation today
WLSSD Solid Waste Ordinance mandates businessdiversion of pre-consumer organic waste. (Oct 2006)
Phased roll-out of mandate covering ~150 businesses &institutions (2007-2010)
WLSSD established a trial drop site program in 2004
Why:
• No curbside collection by private haulers (density!)• Residents wanted an organics recycling option• Compromise: establish sites for centralized collection
How:
• Grant from State of MN• bio-compostable bags & Norseman curbside bins
• hauling costs
• Phased implementation• 3 residential/small business sites in 2004 (2 staffed by WLSSD)
• 7 sites in 2010 (6 residential, 1 business-only drop site)
Objectives
Provide greatest access at minimal distance to users
Maximize capture of residential and small businessfood residuals + intermittent special events
Explore and address challenges:
• Odors/pests?• Contamination/dump and run?• Adequate size/type of container?• Frequency of collection?• How best to educate/recruit users?• Viable alternative to curbside collection?
Started small with 3 sites and 1 hauler
Five businesses host drop sites now
Businesses provide oversight at non-WLSSD drop sites
Customer traffic (positive impact)
Community partnership/common vision
Shared or covered costs of disposal
Bins are sized to need & most are locked after hours
Today, 6 years later…
WLSSD still supplies bags at most sites (reduces slop factor for users)
WLSSD covers hauling costs at all but one large restaurant site (shared)
Reduced pick-up schedule November – May (cold) reduces hauling costs
Users make the best site monitors and program cheerleaders
Contamination remains extremely low; 2 sites no longer lock their bins
Tonnage has increased steadily since start-up (hard data for years 1-4)

Getting the word out
WLSSD’s Drop Site Program
In a perfect world…
• Cheaper hauling costs• More drop site locations• Better bins & trucks• Frequent cleaning• No maggots in July
But it works…
• Human scale that folks appreciate• Fulfills need – manageable size• Room to grow – we determine the rate• Many requests to add sites• Loop is closed locally
