Environment
According to the corporate Environmental Policy, as specified by the Company’s ISO 14001:2004-certified Environmental Management System, adherence
to and compliance with all regulations and requirements which refer to environmental issues and concern its operations is a core commitment for METKA S.A.
Management of natural resources
The activities of METKA S.A. concern the manufacturing and assembly of products, i.e. they involve the use of complex materials/products such as turbines, power
generators, pumps etc. for incorporation in its products, and the use of more simple materials/products, such as merchant bars (beams, pipes, steel plates, axles,
cast parts etc.) for manufacturing (cutting, welding, processing, hardening) in its industrial facilities or in those of its subcontractors. The manufactured products
are then taken to the project construction sites, so that assembly/erection of the final product (e.g. a power plant) can take place.
Thus, METKA S.A. does not manage primary natural resources, but instead manages semi-finished or finished products in accordance with the detailed plans/
blueprints and procedures for each project, which specify with great accuracy all materials to be used, their manufacturing method and their precise position and
operation. These plans/blueprints are the Company’s know-how, which conforms to the latest developments in the respective fields of expertise.
Energy consumption & conservation
According to the Environmental Policy of METKA S.A., the Company’s efforts focus on a number of initiatives which were reported in detail in the Sustainability
Report 2010. These initiatives are carried out throughout the year and involve the application of practices for the rational use and conservation of energy. The
table below lists in summary the relevant actions taken in 2011 and the energy savings that these helped achieve.
