• We pump underground water to keep our quarries in good condition and use water to transform our minerals. The Group encourages the operations to reduce consumption, increase recycling and control the quality of water discharged.
• Our activities produce relatively small quantities of industrial waste. This is because minerals are mainly converted by mechanical (e.g. grinding) and physical (e.g. density separation) processes.
• Fuel use is the main source of CO₂ emissions in the physical transformation of minerals. The Group aims to improve its energy efficiency and it is looking for ways to replace fossil fuels with alternative energies.
• Oxides of nitrogen (NOx) and sulfur dioxide (SOx) are also emitted from the combustion of fuel in our conversion processes. Controls on the emissions of these materials are becoming stricter in many countries. We intend to be proactive with respect to those controls.
• The surface area affected by mining is kept to a minimum and it is continuously restored whenever possible. In addition to the compensating measures taken, quarries offer many opportunities to enhance biodiversity, especially through their end-of-life remediation.
