TYPES OF ENVIRONMENTAL TECHNOLOGIES

cleaner production ET (CPET)

vs

end-of-pipe ET

slide5

End-of-pipe ET vs clenaer production ET

  • End-of-pipe ET: correction of pollution: sewage treatment, air, noise and waste.
  • Cleanerproduction ET (CPET): pollution prevention at source, to minimize resource consumption (cleaner production, recycling / substitution of materials)
  • Major economic and environmental advantages of TPL
  • The EMS (EMAS, ISO 14001) encourage the use of TPL (+ info)
  • Obstacles to the TPL:
    • Legislation that promotes the use of TA end of line
    • Difficulty of implementation
    • Difficulty in assessing the environmental improvement
    • Lack of initiative from the company
  • Changing trend:
    • 20th century: end-of-pipe dominance
    • 21st century: CPET predominance (≈ eco-innovation)
