and services to the Finnish concrete construction industry. The
production sites in Åminnefors and Espo are situated close by the
most active and populated construction areas in Norway, minimizing
transportation distances.
Celsa Steel Service has the expertise to provide advice and
assistance for the reinforcement of concrete and offers products
and services that serve to reduce workplace execution times
through efficient planning and adequate logistic solutions.
Celsa Steel Service is the largest manufacturer of concrete reinforcing
products in Finland. Products range from cut and bend,
mesh, BAMTEC ® , to an extensive production of prefabricated reinforcement
elements (special welded products).

ABOUT THE EPD
This Environmental Product Declaration (EPD) contains the real
facts from a Life Cycle Assessment (LCA) and provides information
that can be used in order to put into perspective different
steel sourcing. For Celsa Steel Service the EPD is a document that,
together with the environmental report from Celsa Armeringsstål,
shows a company investing in technology and technical solutions
that affects the total environmental impact of its products.
Celsa Steel Service AB is certified according to ISO 14001, and
works for a sustainable development of the environment. This
dedication motivates a quest to minimize material and energy
use, but also to seek possibilities to increase the efficiency and reduce
heavy work and unhealthy environments for people working
with reinforcement. The company, as a part of CELSA Group,
has the safety as the first priority and the company has incorporated
safety in all its daily activities.
For the products delivered by Celsa Steel Service, the upstream
processes that include the scrap processing and the steel
works is the dominating emitter. Apart from the upstream processes,
the environmental burden is dependent on transportation
distances, efficient logistics, the level of prefabrication
with minimum material use, and efficient installation at the
construction site. Construction sites have the potential to be
more sustainable by limiting the number transports, handle materials
more efficiently, and implement routines to reduce wastes.
Material for the production of reinforcement steel comes from
the group’s steel and rolling mill in Mo i Rana, Norway. Celsa Nordic
has during many years invested in new technology, not only to
conform to, but to exceed environmental demands in Norwegian
legislation. All these investments have together a major impact
in the production of more environmentally friendly reinforcement
steels in all stages of the production; i.e. the steel mill,
the rolling mill, and transportation.
Environmental benefits also come from the location of the mill
in northern Norway. The use of hydropower reduces indirect emissions
and the water used in the processes is naturally sourced
from immediate surrounding water magazines without any energy
input for retrieving it. The water is available in the processes
but is also generating electricity in the industrial park before
reaching sea level.
Celsa Nordic has been an environmental pioneer in Norway by:
• Producing its first environmental report according to NS-EN
ISO 14001 already in 1996
• Becoming one of the first mills in Europe to get the EMAS mark
in 2010.
• A 100 % scrap based production, being the largest recycling
company in Norway.
• Reducing mercury emissions as well as primary and secondary
dust emissions, recognized by the Norwegian Climate and
Pollution Agency (Klif).
“We take into account the environmental,
social and economic consequences of the strategic
decisions we make in all our daily tasks”

PRODUCTS
Celsa Steel Service works in close relationship with its customers
with the detailing, fabrication and deliveries of reinforcement.
The production involves cutting, bending, and welding of custommade
reinforcement products for all types of concrete constructions.
The EPD considers reinforcement steel made out of hot rolled
products, transformed into straight ribbed bars, cut and bend,
mesh, and combinations of these (special welded products).

CATEGORIES OF IMPACT
2 Acidification
a phenomenon whereby atmospheric precipitations have a lowerthan-normal
pH value, which can cause damage to forests and
crops, and to aquatic ecosystems and manufactured items. It is
due to emissions of SO 2
, NO x
and NH 3
, which are therefore included
in the Acidification Potential (AP) indicator, expressed as
SO 2
-eq.
4 Ozone depletion
degradation of the stratospheric ozone layer, which blocks the
ultra-violet component of sunlight, by means of highly reactive
compounds originating from chlorofluorocarbons (CFCs) or chlorofluoromethanes
(CFMs). The substance used as a reference for
the ODP (Ozone-Depletion Poten-tial) is trichlorofluoromethane,
or CFC-11.
1 Greenhouse effect
a phenomenon whereby infra-red rays emitted by the earth’s surface
following solar heating are absorbed by molecules present in
the atmosphere and reemitted in the form of heat, causing global
warming of the atmosphere. The indicator used here is the GWP
(Global Warming Potential), which covers emissions of carbon dioxide,
the main greenhouse gas, and other gases with a higher
degree of infra-red absorption, such as methane (CH 4
), nitrous
gas (N 2
O) and chlorofluorocarbons (CFCs), which are expressed
as a function of the degree of absorption of CO 2
(g CO 2
).
3 Eutrophication
the enrichment of watercourses with nutrients, which causes imbalances
in aquatic ecosystems due to overdevelopment as the
result of a lack of nutritional limitations. Eutrophication Potential
(EP) mainly covers phosphorous and nitrogen salts, and is expressed
as PO 4
3-
eq.
5 Photochemical ozone creation
the production of compounds which, by the action of light, are
able to promote an oxidation reaction that leads to the production
of ozone in the troposphere. The POCP (Photochemical Ozone
Creation Potential) indicator mainly concerns VOCs (Volatile Organic
Compounds) and is expressed as equivalent weight of ethylene
(g C 2
H 4
).
