The Indaver Relight facilities in Doel, Belgium, treat all mercury-containing lamps which are collected selectively in Belgium, half the fluorescent lamps, low-energy light bulbs and other gas discharge lamps collected in the Netherlands and a third of those collected in France. All together it accounts for around 30 million lamps a year. Up to 95% of the lamps is recycled, especially glass and metals which, cleared of mercury, are reused in the manufacture of new lamps or in the metal recycling industry. A fine example of the closed loop.
