  1. Single Stream & Beyond California Roundtable May 23, 2005 Sacramento, California Donna Perala City of San Jose

  2. A Little About San Jose . . . • 11th Largest City in US • 945,000 Residents • 200,000 SFD Households • 3,200 MFD Complexes • 90,000 MFD Households Citywide Diversion (preliminary) for 2003: 59%

  5. This Past Year . . . • Service is meeting performance standards • Missed collections at minimal levels • Routes completed by required times • Other services completed on time • Haulers have identified problems with contamination in some areas of the City • Pay-as-you-throw system can encourage residents to put extra garbage in recycling cart • 96-gallon recycling cart may provide contamination opportunities

  6. 4-Sort System vs. Single Stream Comparisons (SFD Tons) 4 - Sort Startup Year 2 % Change FY01-02FY02-03FY03-04FY01-02 to 03-04 Garbage 176,659 167,558 162,939 -7.8% Recycling 86,172 110,915 107,815 25.1% Residue 6,749 33,262 16,614 146.2% SFD Diversion 30.2% 27.9% 33.7% 11.5% Total Diversion w/ MFD & YT 45.0% 43.9% 49.5% 10.0%

  7. San Jose’s Single Stream Challenges • Trade-off for collection efficiencies and convenience = highercontamination • Some Rejected Paper Shipments • Highest and Best Use goals compromised

  8. San Jose’s Single Stream Challenges • Outreach and education to targeted audiences more critical than ever • Business model challenges & opportunities

  9. Business Model Case Studies • Business Model #1 • Collection contractor owns and operates MRF • Business Model #2 • Collection contractor subcontracts processing

  10. Business Model #1 Owner Operated • Contractor has incentive to maximize diversion because: • Gets contract extension ($$$) if meets 35% diversion requirement • Receives bonus payment if achieves over 40% diversion • Stays within Permit and avoids solid waste fees if under 10% residual

  11. Business Model #1 (cont’d.) Owner Operated • Contractor pays $35 / ton to dispose of residual • Contractor motivated to invest in new processing technology and even pay to divert material • 03-04 Average Residue: 7.6% • 03-04 SFD Diversion: 41.6%

  12. Business Model #1 (cont’d.) Owner Operated Innovations include: • MFD Compostable Pilot introduced in 2003 to meet 35% MFD diversion requirement • Installed optical plastic sorter last year • Plans to install optical paper sorters to clean up loads • Pays to recycle hard-to-market commodities

  13. Business Model #2 Processing Subcontracted • Subcontractor has minimal incentive to maximize diversion because: • No direct relationship with the City, so not involved in many contract issues • Hauler, not processor, would receive bonus payment if Sub achieves over 40% diversion • Sub now has Solid Waste Facility Permit so no LEA problems if over 10% residual

  14. Business Model #2 (cont.d) Processing Subcontracted • Subcontractor does NOT pay for disposal of residual • Subcontractor has minimal incentive to invest in new processing technology or look for innovative ways to divert material • 03-04 Average Residue: 17.3% • 03-04 Diversion: 31.6%

  15. Solutions tried so far…. Outreach • Over $2M spent on transition outreach • Over $350,000 / year spent on on-going outreach • Annual hauler outreach requirements • Door-to-door outreach in 2003, visiting 2,000 households in targeted areas

  16. Solutions tried so far…. Enforcement • An average of 360 Non-Collection Notices per month are issued by haulers • Cart upsize policy in place, but emphasizing outreach and education first

  17. What Have We Learned? • Contract incentives help make Single Stream work • take great care when reviewing terms of any subcontracts - take great care to maintain control of materials stream

  18. What Have We Learned? • Outreach and education play a vital role in transitioning to Single Stream and beyond • Consider offering a 64-gallon recycling cart as default size rather than a 96!

  19. Is It Worth It? All-in-all ….. Single Stream is still worth the trade-offs • Fewer worker injuries; reduced labor costs • Participation and diversion have increased • Tonnages of recyclable materials collected have increased • Updated technology and on-going education will help address quality issues
