Glass manufacturers: how are they environmentally responsible?

Basic sheet or ‘float glass’ manufacturing requires furnace temperatures of up to 1500°C and is thus a highly energy intensive process. Large quantities of raw materials – including silica, soda, magnesium and calcium

are required and the process used for smelting them results in carbon dioxide and other gaseous emissions.

Environmentally responsible glass manufacturers, in association with Glass for Europe, are applying new best practices and technologies to reduce their environmental impact.
Using recycled glass, or ‘cullet’, in the basic float glass making process reduces both raw materials needed and energy consumption. The added environmental benefits of using cullet in manufacturing means that energy consumption and CO2 emissions are reduced – and that less used glass is sent to landfill sites.
