Pollution Prevention Pays (3P)
•Pollution Prevention Pays (3P) program in 1975. ▫Goal - eliminate or reduce sources of
pollution in 3M products and processes
•10,000 3p projects since 1975. ▫Prevented > 3.8 billion lbs of pollution ▫Saved > $1.7 billion in their first year.

Water Reduction• Background
▫Two processes Process A
Extrudes resin to form very thin nylon or polyester fibers
Process B Extrudes resin to form
vinyl or Nylon/polyester webbing material
▫Significant opportunity to improve water management
