Integrated Waste Management

• Interconnected / Interdependent System
• More Source Reduction Less Recycling
• More Recycling Less Conversion
• More Recycling Less Incineration
• More Recycling Less Disposal
• More Conversion Less Incineration
• More Conversion Less Disposal
• Conversion Feedstock is Systems Dependent

Conversion Technology (CT)

• CT Feedstock is basically MRF Residual that is
  currently Disposed
• Processing of MRF Residue into CT feedstock
  results in additional recycling or feedstock(s)
  for secondary manufacturing
• CT feedstock is leftovers from source reduction
  and recycling programs

Feedstock Management includes additional
processing of MRF Residuals (Optimizing CT
Feedstock)

Feedstock Management (Preprocessing)

• Preprocessing includes Materials Receiving and
  Storage
• Preprocessing involves additional removal of
  hazardous and non-processible materials
• Preprocessing involves additional recovery of
  recyclables
• Preprocessing includes feedstock storage and
  materials handling

Compatibility with Recycling

• From Systems Standpoint, Conversion Technology
  Compatible with Recycling
• If Conversion Technology occurs AFTER waste
  reduction and recycling programs,
• Conversion Technology creates additional
  potential for recovery (e.g., more metals
  recovery, etc.)
• Conversion Technology is last step before
  disposal / incineration
• Conversion Technology Reduces Landfill Disposal
