we came to this workshop because we care about
“We came to this workshop because we care about….
  • safety of our employees
  • improving bottom-line profits
  • protecting the environment
  • compliance with environmental regulations
“If we don’t know what our environmental expenses are, it will be very difficult to reduce and eliminate them”
tangible environmental expenses
Tangible Environmental Expenses
  • Off-site hazardous waste transporting
  • Landfill fees
  • On-site waste water pretreatment
  • On-site monitoring and testing
intangible environmental expenses
Intangible Environmental Expenses
