CONCLUSIONCONCLUSION

End-of life management should be made apriority in the design of new electronicproducts.

There exists an urgent need for a detailedassessment of the current and future scenarioincluding quantification, characteristics, existingdisposal practices, environmental impacts etc.

Model facilities employing environmentally

sound technologies and methods forrecycling and recovery are to beestablished.
