CONCLUSIONCONCLUSION End-of life management should be made a

priority in the design of new electronicproducts.

There exists an urgent need for a detailedassessment of the current and futurescenario including quantification,characteristics, existing disposal practices,

environmental impacts etc. Model facilities employing environmentally

sound technologies and methods forrecycling and recovery are to be established.
