NATIONAL ECONOMIC DEVELOPMENT AND ROAD INFRASTRUCTURE





ROAD INFRASTRUCTURE VS. ECONOMICAL STRENGTH





A CHANGING BUSINESS LANDSCAPE
  • Need to support population growth and rapid economic development
  • Environmental focus being shifted from pollution prevention to “Sustainable Development”


BASF ECO-EFFICIENCY ANALYSIS
A Decision Tool for Sustainable Development





BASF ECO-EFFICIENCY ANALYSIS

Goal:

To offer customers the best possible alternatives with the least environmental impact at the best cost.

The analysis focuses on:
  • Optimum performance
  • Raw material and energy consumption
  • Recycling and disposal
  • Ecological and economic advantages


“CRADLE TO GRAVE” EVALUATION




ECO-EFFICIENCY ANALYSIS Part 1:
Environmental Impact





ECO-EFFICIENCY ANALYSIS Part 2:
Economical Consideration





BASF ECO-EFFICIENCY ANALYSIS
  • Introduced by BASF in 1996

  • Has been used to identify opportunities for improving the ecological and economic profile of more than 100 different products and processes


Example of BASF Eco-Efficiency Analysis
  • Indigo Dye Production and Dyeing Process
    • Indigo from Plants
    • Indigo from Biotechnological Process
    • Indigo from Electrochemical Process


Energy consumption of Indigo dyeing




Ecological Fingerprint of Indigo dyeing

CONCLUDING REMARKS
  • Eco-efficiency Analysis provides integrated assessment of preventive maintenance technologies.

  • Microsurfacing appears to have the least environment impact with competitive costs among the three alternatives studied.

    • less materials being used

    • less transportation

    • lower emissions

  • Further improvement in microsurfacing technologies could lead to significant cost and environmental advantages
