HHW Collection in Tacoma

what we will cover
What we will Cover
  • Background on Tacoma HHW Programs
  • The Evolutionary process of HHW Collection in Tacoma
  • What we learned along the way
  • What our future challenges will be
tacoma hhw collection
Tacoma HHW Collection
  • The stadium years
    • 1987 through 1990
    • Collection Events at Cheney Stadium
    • 462 customers at first event
    • Last event two sites over multiple days
    • 1990 event - 1817 Participants
what did we learn
What did we learn?
  • The early events in Tacoma were:
    • Very expensive $60.00 – 90.00/participant (Operations only!)
    • Very stressful
    • Used a lot of staff
    • Not sustainable over the long haul
landfill superfund issues
Landfill Superfund Issues
  • If we implement an “effective” HHW program, we can keep our last remaining cell open
  • Used our HHW experience to develop a fixed facility with small scale mobile collection system
tents parking lots
Tents & Parking Lots!!
  • 1990 – 1994
    • Temporary fixed facility (tents and trailers)
      • All Waste handling under tents
      • Serve Tacoma residents only
    • Mobile facility
      • All sites in Tacoma
      • Accept HHW in field, transport back to facility for processing and shipping
      • Two weeks per event
what did we learn part 2
What did we learn (part 2)
  • Fixed facility had most impact
    • Steady increase in use and volume
    • Open 7 days per week
    • Technicians became extremely efficient with poor facilities
mobile facility
Mobile Facility
  • Mobile facility – unsatisfactory response
    • Some locations too close to fixed facility
        • Response rate evaluation
    • Hours of fixed facility more convenient
    • Low participation = inefficient & inefficient
    • Direct mail was effective and controllable
a permanent home
A Permanent Home!
  • New facility in 1994 - What did we learn (part 3)
    • Facility used at a fraction of capacity
    • Technicians much more efficient = more down time
      • Need more customers or less open hours
    • Still doing collection events with Pierce County – large 1 day events
    • Interlocal Agreement with County
cooperation helps efficiency
Cooperation helps Efficiency
  • Interlocal Agreement
    • Increased use of facility by over 50%
    • County reimbursements pay for their share of operations, plus capital and some overhead
    • Facility more efficient and cost effective
    • Eliminate large collection events for good, start “Satellite” program
satellite program
Satellite Program
  • Designed and built by the Technicians
  • Base facility is a modified rolloff
  • More secure, easier to move, environmentally safer
  • 3 days per week
satellite program1
Satellite Program
  • Careful site selection – balance population of the target area and availability of service for that area
  • Average 30 customers per day
  • Approx. $25.00 per customer – Ops only
big picture lessons
Big Picture Lessons
  • Continued evaluation is critical – doesn’t need to be a big process
  • It is the employees and not the facilities that make the program
  • Partners that pay are nice!
big picture lessons the obvious
Big Picture Lessons (the obvious)
  • Facilities/Service
      • Location
      • Space – build as much capacity as you can afford
  • Operators need to be involved with facility and equipment purchases
      • Material flow, safety
      • Applicability of equipment
the challenges ahead
The Challenges Ahead
  • Integrating the HHW collection program with sustainability
      • How do we fit in with promoting less toxic material, less chemical use, behavior change
  • Product Stewardship
