WM/RAA in California

WM/RAA is California’s largest recycler of MSW

WM/RAA operates approximately 24 Recycling
facilities in California

Of those 11 do Single Stream processing

RAA Markets over 500,000 tons per year from
California not including glass

WM/RAA has invested over $25 Million in SS
technology in California

A vast majority of our residential recycling customers
are serviced with single stream collection

Diversion is King
•
•
Residential

Historic - 25% recycling / 75% disposal

Current Goals - 75% recycling / 25% disposal
Commercial

Historic - Grade Specific (OCC, SWL, SOP)

Current - Grade Indifferent – Commercial
Single Stream Processing
Diversion is King


Higher participation rates (participation rates)
–
convenience
–
simplicity (potentially fewer restricted materials)
Higher recovery rates (lbs/hh/mo)
–
higher participation
–
more materials in programs
–
reduced scavenging
Diversion is King
•What do our numbers show?
 Based
on a survey of California managers
we estimate 20-30% increase in volume
after switching to SS
 Northwest USA
- Tons collected in Skagit and Snomish
County (125,000 HH’s) show tonnage
increases of between 7 and 36% after
converting to SS
Diversion is King
•What do others numbers show?
 Dallas,
Tx (pilot program)
- 6 lbs/HH/Mo vs 54 lbs/HH/Mo
- 25% participation vs 74% participation
 Brooklyn Park & Hennepin Recycling Group
(41,000 HH)
- BP 40 lbs/HH/Mo vs 49 lbs/HH/Mo
- BP 46% participation vs 72% participation
- HRG 36 lbs/HH/Mo vs 47 lbs/HH/Mo
- HRG 50% participation vs 71%
participation
Safety is Key Driver
 Key
Concerns
– Safety of our workers
– MSW workers – third deadliest occupation
in Florida (1993-1997)
– Almost 50% of all MSW workers might
expect to suffer muscoskeletal or dermal
injuries each year
Safety is Key Driver
 Reduced
collection safety risks (twisting,
sprains, cuts, etc.)
+
 Reduced MRF safety risks (cuts, etc.)
+
 Reduced TRIR (both collection and
processing)
+
 Reduced employee turnover
=
 Lower workmen’s comp costs
Efficiencies and Economies

Optimize fleet utility
— Increase payloads
— Reduce drive-times

Improve safety

Increase opportunities
— Commercial Single Stream
— Multi-family
Efficiencies and Economies
•
MRF Equipment
 Capital
intensive ($1MM to $6MM for equip)
 Increase production (30 – 40 tph throughput)
 Auto-assist separation (screening, optical)
•MRF Operation
 Improve
safety (TRIR reduction)
 Improve presentation of material for sorters
 Improve flexibility & market access
Processing Challenges
 Increased residue levels
• Typical 2-stream MRF has about 4% residue (blended value of fiber and container residue)
• Typical single stream MRF has 6-8% residue
• What we are doing: can reduce to less than 4 % with no sort glass and no sort plastic technologies

Glass breakage
• Typical commingled containers has 50-60% glass breakage
• Typical single stream has 60-90% depending on vehicle and compaction ratios
• What we are doing: can minimize effect with optical sorting and better screening

Quality control of collected materials in fully automated routes
• What we are doing: Use manual or semi-automated routes and using route checkers
Processing Challenges
“The quality of the product going to market. We’ve got to make
sure that what’s going into the bales is meeting the specs of the mills.”
RAA President Pat DeRueda at Waste Expo commenting on
the biggest challenges recycling faces.
Summary of Benefits

Increased diversion through improved participation &
lbs. per set-out

Reduce unit costs (time per stop, trucks on street, &
processing costs per ton)

Greater employee safety

Improve aesthetics & convenience

Making residential recycling economical and
sustainable

“Securing” and growing the residential fiber stream
