Solid Waste Management Versus Materials Management
Quote from John Skinner SWANA Newsletter, June 13, 2013 More than ever, solid waste managers need to make the transition from the waste disposal business to a resource management industry. They need to recognize that they are suppliers of raw materials and not only disposers of discarded wastes.
The Residential Collection Mix: 1992: Newspaper Glass bottles and jars Aluminum cans Soda bottles Milk jugs Steel cans Then and Now 2013 All of the 1992 list, plus: Magazines and office paper Mixed paper OCC All #1 and #2 plastic bottles Other plastic containers Aerosol cans Gable tops & aseptics Bulky rigid plastics (sometimes)
Estimated Per Household Generation Tons of solid waste: 1.04 (2,080 lbs) Recyclables: 0.35 T (700 lbs) Food waste: 0.21 T (420 lbs) Bulky waste 0.077 T (154 lbs) Leftover solid waste: 0.403 T (806 lbs) Leftover Solid Waste, 38.8% Food waste, 20.2% Recyclables, 33.7% Bulky Waste, 7.4%
Which of these things are waste?

Key Trends Declining and changing waste stream Growing secondary materials economy Technological advancements Economic volatility Resistance to tax and fee increases Tighter fiscal situation Demand for more services
Responding to the Trends Efficiency Cost Effectiveness Local government solid waste/recycling managers should seek to maintain and deliver services that maximize public value. Key examples: Solid Waste Automation, routing, reduction of disposed tons Careful capital planning of landfill assets Recycling Automation, routing, participation, material mix, new materials Access to MRFs and stable and fair MRF relationships

Efficiency
Bins The Evolution of Curbside Single Stream Recycling w/carts Collection Three Cart System: Garbage, Recycling, and Composting Difference in Performance: Average Bin-based program: 247/household/year Average Cart-based programs: 445/household/year
The Convenience Center of the Past and Present Glass Mixed Paper Cardboard Plastics Aluminum & Steel Can Bin Trash Compactor Office Swap Shop & Oil Shed Newspaper Scrap Metal Cooking Oil & Electronics Bulky Trash Trash Pre-Crusher
The Convenience Center of the Future: Single Stream Using Compaction
Internal Hub and Spoke: Moore County Doubling of recycling tons 75% reduction in travel time Repurposing of containers Use of compactors = Single stream convenience collection = Single stream transfer station Transfer out to Pratt MRF in Fayetteville.
Improving Efficiency: Hubs & Spokes Transfer of Recyclables = good candidates for transfer = transferring county = accessible single stream MRF
Other Collection Activities Cooking Oil Recycling Carpet Recycling Mercury Lamp Collection Electronics HHW Oil and oil filters

Measures Measurement extremely important Key measures Cost per ton (SW and Recycling) Cost per household (SW and Recycling) Lbs per household served (SW and Recycling) Set-out rate (Recycling) Participation rate (Recycling)
More important to Reduce costs than make money
Vision of the Materials Management in NC Recycling and organics diversion on par with garbage (or better). Material flows are optimized. NC economy is more competitive because of efficient access to recovered materials. Long term dependence on landfills and associated liabilities are minimized.
