Abstract
For recovery of fluorescent material and Hg from burnt-out or non-functioning fluorescent lamps, the ends of the gas discharge vessel are removed and the fluorescent material and Hg are blown out in at least blowing-out procedure with a gaseous medium loaded with fluorescent material and opt. Hg. A venturi arrangement can be used for supply of the gas, which can be that from the previous blowing out operation. Type of fluorescent material can be determined optically before the initial blowing out.
