In the Construction & EPC Projects sector, our
activities concern mainly the manufacturing
and assembly of products, i.e. they involve the
use of complex materials/products such as tur-
bines, power generators, pumps etc., togeth-
er with more simple ones such as merchant bars
(beams, pipes, steel plates, axles, cast parts
etc.) for manufacturing (cutting, welding,
processing, hardening) in our industrial facil-
ities or in those of our subcontractors. The
manufactured products are then transported
to the customer’s facility / construction site,
where assembly/erection of the final product
(e.g. a power plant) takes place.
Our subsidiary METKA S.A. does not manage
primary natural resources, but instead manages
semi-finished or finished products, in accor-
dance with the detailed plans/drawings and
procedures for each project, which specify with
great accuracy each material which will be
used, its manufacturing method and its exact
position and operation. These plans/drawings
and procedures represent the company’s
know-how, which conforms to the latest de-
velopments in the respective fields of expert-
ise.
The percentage of the use of recycled mate-
rials in the implementation of projects during
2013 stood at 28.8%.
**
Additionally, our requests for proposals and
contracts with suppliers of materials and
equipment contain a specific clause regarding
their compliance with the requirements of the
ISO-14000 International Standard, specifically
regarding the prohibition of using environ-
mentally hazardous materials and the obli-
gation to use recyclable materials to the high-
est possible degree.
In the Energy sector, the raw material used in
our thermal power plants is natural gas,
which cannot be recycled and is a non-re-
newable material.

n the Metallurgy & Mining sector, during
2013 we used more than 2.1 million tons
of raw materials (on dry basis) to produce
aluminium. Recycled materials or alternative
raw materials (by-products and waste dis-
posals from other industries) are not used for
the time being in the aluminium production
process to lower the consumption of raw ma-
terials.

The lime furnace did not operate during 2013.The quantity required for the production process was purchased from an external supplier.

Of the 320 tons of total weight of materials used, steel in the form of plates or merchant bars accounts for approximately 230 tons. Around 40% of the
EU’s total steel production comes from electric arc furnaces, in which steel is produced from 100% recycled raw material (scrap). Thus, the recycled steel used
in our projects is estimated at 92 tons (40% of 230 tons).
