We work to reduce our environmental impact and use natural
resources efficiently through the adoption of management systems
for the main environmental aspects of our activities. - 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 ma
