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.”

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

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.
