MYTILINEOS HOLDINGS SUSTAINABILITY REPORT
2015
8.3 Energy
The total consumption of energy at the Group’s industrial plants
in 2015 stood at 35,954.58 TJ. This quantity was obtained from
non-renewable sources only and posted a 12.9% increase com-
pared to 2014, mainly due to the increased participation of the
thermal power plants of Protergia in the wholesale electricity
market. The consumption of electricity rose by 3.9%, while the
consumption of energy from fuels (mainly natural gas) rose by
16.5%.

* From Non-Renewable Sources
The percentage of the use of recycled materials in the imple-
mentation of projects in the EPC Projects Sector in 2015 stood at
34%

G4-EN2
. Additionally, a key criterion in the design stage of
the projects that METKA is carrying out as an EPC Contractor is
the maximum possible use of recyclable materials. The compa-
ny’s requests for proposals and the contracts with suppliers of
materials and equipment contain a specific clause regarding their
compliance with the requirements of the ISO-14001 International
Standard, specifically referring to the prohibition of using envi-
ronmentally hazardous materials and the obligation to make the
maximum possible use of recyclable materials.
In the
Energy Sector
, the raw material used in the Group’s power
plants is natural gas, which cannot be recycled and is not a re-
newable source.
G4-EN2
In 2015, the consumption of natural gas at
the thermal power plants of Protergia grew by 54.1% compared to
2014, due to the increase in the production of electricity.

Of the 471.98 tonnes of total weight of materials used and incorporated in the end products, steel (in the form of plates, merchant bars or other project
materials) accounted for approximately 400.93 tonnes. Around 40% of the EU’s total steel production comes from electric arc furnaces, in which steel is
