Increasing ecological constraints linked with economic advantages have induced the recycling of cullet predominantly in the container glass industry as well as the recycling of filter dust in various branches of glass production. The recycling of cullet originating from non-returnable glass packaging was introduced more than 20 years ago, whereas the recycling of filter dust originating from waste gas treatment was started only recently. The transition from employing basically constant raw materials to utilizing increasing amounts of recycled glass as the major batch material and the introduciton of filter dust as an additive have imposed new challenges on glass melting.
