is this a lasting trend
Is this a lasting trend?
  • Cradle to Cradle
    • Book published in 2002
    • GreenBlue started about same time
    • Formed Sustainable Packaging Coalition.
  • Wal-Mart Scorecard, California Waste Initiative
  • Changes in Society –
    • Energy Costs?
    • Global warming?
    • Increasing global population?
    • Throw-away society?
  • Obama Administration – Green Initiatives
sustainability
Sustainability
  • Definition: Is beneficial, safe & healthy for individuals and communities throughout its life cycle.
  • Terminology
    • Green, Environmentally Friendly or Degradable (OUT)
    • Specific Claims (IN)
      • Biodegradable or Compostable
      • Recycleable, Recycle content, Lightweight, Reduced, Reuseable
      • Information on how to dispose of package.

myths and reality
Myths and Reality
  • Myth
    • Sustainable packaging costs more.
  • Reality
    • Yes, if
      • using a new material or process that costs more initially
      • using return/wash/reuseable
    • No, if
      • source reducing
      • pallet-cube efficiency
      • light weighting
      • reusable in closed loop system
sustainability1
Sustainability
  • Myth
    • Degradability Claims
  • Reality
    • Yes, if
      • Meets ASTM 6400
      • Aerobic, Anaerobic or Marine?
    • No, if
      • Goes to Landfill
      • Can contaminate recycle stream
      • Can’t separate degradable component from non-degradable
sustainability2
Sustainability
  • Myth (Issue)
    • Food vs. Fuel vs. Package Debate - Ethanol
  • Reality
    • Less than 5% of petroleum is used for plastic, only a portion of that is used for packaging
    • Less than 0.5% of world’s corn needed to make biopolymers if all plants currently available were running at full capacity.
    • Ethanol to produce fuel doesn’t significantly affect fuel prices
    • Corn is a commodity, price controlled crop
sustainability3
Sustainability
  • Myth (Issue)
    • Recycling – limited to only PE and PET
    • Foods cannot be contained in pkgs with recycled content
  • Reality
      • Higher demand for RPET and RPE but others can also be recycled.
      • Recent pkgs. with recycled content:
conflicts
Conflicts
  • Convenience can lead to over-packaging
  • Technology – RFID & EAS
  • Active Packaging
  • Infrastructure
metrics
Metrics
  • Carbon Footprint
  • Carbon Offsetting
  • Wal-Mart SVN
  • SPC
  • LCA
  • UN – Kyoto Protocol
  • SPC – ComparativePackaging Assessment (COMPASS)
  • Calif. Integrated Waste Mgmt Initiative
  • DSD – Green Dot
  • LCI database
  • GHG calculator
  • EPA
  • Organizations that provide certifications
current approaches
Current Approaches
  • Landfill – still number one way to handle waste
  • EPA Hierarchy
  • Composting and Biodegradables
    • more common in UK and Europe
    • ability to handle the volume?
design guidelines
Design Guidelines
  • Does the design reduce disposal cost?
  • Does package clearly communicate disposal information?
  • Can the package be separated, recovered, recycled cost effectively using current methods?
  • Can package be made of renewable materials?
design guidelines1
Design Guidelines
  • If incinerated, effects on quality of air, water or soil?
  • Consider consequences of down gauging too much.
  • Avoid mixing materials whenever possible or make it easy to separate materials.
design guidelines2
Design Guidelines
  • Involve entire supply chain
    • can alternative energy sources be used for production or shipping?
    • reduce overall environmental impact during manufacturing, transportation, disposal and recovery.
  • Work with product development
  • Quick fixes and Long term solutions need to be considered

Why should military food suppliers be concerned about sustainability?
  • Solid Industry Trend
  • Can have a positive impact on business
  • Can save $ and give companies a leading edge.
