New Recycle System on Discarded Florescent Lamp by using low Temperature Thermal Treatment with some Modifide.

摘要

We succeeded removing 99 pencent mercury from mercury-polluted sediment by using low temperature thermal treatment (Minamata bay sediment Hg 200 mg/kg.drywt). In this time, to develop the new recycle system for discarded florescent lamp, we used low temperature thermal treatment with some modified. As a result, mercury content in the discarded fluorescent lamp as waste was removed more than 95 pencent and the value of leaching test was less than 0.005mg/L by using our technology. The recycle system which is used our technology is operating as practical use in Japan now.
