Our efforts regarding the rational
management of raw and other ma-
terials focus on the identification and
specification of suitable methods,
which will allow our subsidiaries to al-
so use recycled materials in process-
ing and manufacturing of their prod-
ucts. The maximum possible use of re-
cycled materials in our production
processes will help reduce demand for
virgin materials, maintain the level of
mineral resources and reduce total op-
erating costs in our Group. Today, the
percentage of the use of alternative
raw materials in MYTILINEOS Group,
especially in aluminium production
and in construction, does not exceed
20%.
On the other hand, a particularity of
the Energy sector is that the raw ma-
terial used to drive our electricity
production plants is natural gas,
which cannot be recycled and is not
a renewable source.
During 2012, a total of 2.37 million
tons of raw and other materials were
used to produce the Group's end
products, down by 5.2% from the
quantity used last year. The largest part
of this quantity came from the mining
activity and involved the consumption
of bauxite in aluminium production.
