What is LCA?Life Cycle Assessment (LCA) is an environmental assessment tool for evaluation of impacts that a product (or service) has on the environment over the entire period of its life – from the extraction of the raw materials from which it is made, through the manufacturing, packaging and marketing processes, and the use, re-use and maintenance of the product, and on to its eventual recycling or disposal as waste at the end of its useful life

3. Introduction to EcoDesignProduct Design is a critical determinant of a manufacturer’s competitivenessNational Research Council, USA: estimates that 70% or more of the costs of product development,manufacture and use are determined during theinitial design stagesBad design leads to inefficient use of resourcesand excessive wasteTrade Barriers using environmental aspects(packaging / hazardous substances / product recyclability etc.)

14

What is EcoDesign?EcoDesign is a design approach that leads to a profitable balance between ecological and economical requirements when developing products.The total life cycle of a product is the basis on which EcoDesign builds its strategies. From cradle to grave, environmental issues are considered for each stage the product goes through.

15

What can be achieved with EcoDesign?

Considerable reduction in environmental load (e.g., 30-50% or higher) – often feasible in short termSaving of materials and energyReduction in wasteInnovative product designConsiderable reduction in costs

• A win-win situation – benefits for both business and environment• Through a number of small steps - rather than a single large breakthrough• Take only a little logical thinking on familiar products

4. Pilot Project: Eco-compressor

Collaborative project between government and industry strategic partnerSigning an cooperative agreement between MTEC and SUE (KPC) on August 27, 2003As a pilot project of the NETH program of GMTAP

24

Demonstration Project to Produce Prototype of a more Environmental Friendly Compressor

Redesign partsCast iron parts

25

Expected Output of Pilot Project

• A good demonstration project for Thailand that combines both LCA and EcoDesign into one project.

• Creat a group of core researchers who have practical experience in LCA and EcoDesign.

• The production processes of motor case + cylinder & piston + slider are expected to be reduced ~50% by changing from “Casting” to “Sintering”. Reduce energy, resources,and environmental impacts from the production.

• Developing strong relationship among MTEC & private company & Japanese counterparts (e.g. JETRO, JODC)

26

Current SituationEco-Design Part

o JODC-Expert dispatch: Mr.Akira Arai, visit 3 times (7-11 June 04, 22-26 Nov 04, 7-11 Feb 05)
