Glass or ceramic manufacturing installations use continuous fire processes (furnaces) which require the use of energy. In this respect, they can cause significant air emissions (SO2, NOx, CO2 etc.) resulting from the combustion as well as the process.
Glass industries reduce their consumption of energy and raw materials by recycling glass (cullet) and reducing melting temperatures. They can generate metal emissions into the air (notably lead). In addition, the risks associated with the presence of high temperature materials (molten glass) should be taken into account.
A sectorial monograph on the Glass Industry was written by the Ministry for Ecology, Sustainable Development and Spatial Planning.
National programme of atmospheric pollutant emissions reduction: annexes A, B and C of this programme relate to mesures relative to the reduction of sulphur dioxide (SO2) emissions, nitrogen dioxide (NOx) emissions and volatile organic compounds (VOC) emissions.
Substance strategy nationwide action: the strategy of management and reduction of atmospheric toxic emissions for health, identified as one of the main action of the national health and environment action plan (PNSE), is aimed at 6 atmospheric pollutants (benzene, monomer vinyl chloride, cadmium, dioxins, lead, mercury) and several industrial sectors, especially glass industry. Regarding facilities of the glass industry sector, a national aim has been set : emissions of lead and cadmium must be reduced by 50% between 2000 and 2010.
Glass and ceramics: these two sectors are concerned by the directive on the emissions trading scheme and the National Quota Allocation Plan (PNAQ).
