In glass-making, water is used for cooling; most of our plants operate with closed loop systems and so only require top up. Water used for washing glass in plants needs to be of very high purity, so water is treated and then reused. We minimize our water consumption by working with suppliers to recycle water and to install advanced water treatment facilities. This reduces water consumption and the use of treatment chemicals.
Across the Group, water consumption can vary considerably according to process and product demands as well as water quality. Approximately two cubic meters are required to manufacture one tonne of float glass and approximately 90 liters are required to process each square meter of automotive product. We withdrew a total of 20.9 million cubic meters of water in 2016. Our Group risk assessment shows that our largest water consuming sites are located in countries that do not have water supply issues.
