Touches On Many Other Sectors Such As Textile Presentation Transcript

  • 1. Greening the Supply Chain “ Pollution Prevention for Product Systems” John O. Sparks U.S. Environmental Protection Agency Design for the Environment Program
  • 2. Extraction conversion Unsustainable Product Life Cycle Material Flows & Life Cycle Concepts Discharges to air, land, water in all stages Stuff Dispose Manufacturing Use
  • 3.
    • 12,000,000 new cars/light trucks made annually
      • about 20,000 parts per unit and most are out-sourced
    • Total finished product is 24,000,000 tons
    • Estimate about 3 lbs. non-product output per lb. of finished product
      • cleaners, lubricants, scrap, process sludges, etc.
      • could be much higher if process waters included
    • Non-product output approximately 72,000,000 tons
    • Most in the suppliers facilities
    • auto company & public ultimately pays for waste .
    OEM Supply Chains Example:Auto Assembly Impact
  • 4. Material Flows & Life Cycle Concepts GSC Vision :Sustainable Product Life Cycle Fewer discharges to air, land, water in all stages End-of-life Disassembly Assembly & Manufacturing Use Servicing Repair Inputs Dispose Re-manufacturing & Recycling Design
  • 5. Environmental Impact Potential: 4 Workshops
    • Reduced Electricity Demand:
      • 1, 880,000 – 1,915,000 kWh annually
    • Reduced CO 2 Emissions:
      • Transport related reductions
      • 149,800 – 150,200 lbs. annually
    • Reduced Transport Fuel Use:
      • 21,990 – 22,080 gallons annually
    • Reduced Solid Waste Disposal:
      • 278,000 – 319,000 lbs. Annually
    • Additional environmental opportunities:
      • Paint disposal reduction
      • Steel scrap reduction
