Iron technology leader Saint-Gobain PAM UK, part of leading international materials company, Saint-Gobain, has further demonstrated its environmental commitment through several major investments at Holwell, near Melton Mowbray, including one which has seen CO2 emissions from its cupola furnace – the biggest of its kind in the UK – fall dramatically.
The previous installation of a dry bag filter system has meant particulate emissions have been reduced by 99 per cent from the cupola furnace. As a result, emissions are now less than 0.3kg per tonne of castings, while the company has reduced site water use by 63 per cent and electricity by 9 per cent, and completely eliminated the use of caustic soda previously employed for cleaning the wet filtration system. The move also brings a reduced risk to permitted drainage discharge points.
