Hot-rolled reinforcing steel for concrete in bars and coils
Alfa Acciai group comprises several well-established companies specialized
in various areas of the production of steels for reinforced concrete, a
guarantee of products and services qualifying the Brescia-based group as an
excellent business partner in a wide range of sectors, first and foremost in building
construction.
Being involved in the entire steel production chain, with an integrated system
upstream and downstream of the parent company, the Alfa Acciai group is able
to meet its customers’ operating requirements to the full and guarantee a superior
standard of quality at all stages of the production process.
1. alfa acciai Group
ALFA ACCIAI, the Brescia-based
parent company, is one of the largest
eAf steel mills in italy. there are a steel
shop department with 2 eAf (electric
arc furnaces), 2 lf (ladle furnaces)
and 2 continuous casting machines (10
lines). the hot rolling department is
equipped with 3 rolling mills for rebars,
coils and wired rod; the cold rolling one
with 12 cold rolling mills 5 welded mesh
machines.
ACCIAIERIA DI SICILIA, is the only
steel mill operating in Sicily, based in
catania. High production capacity, state-
of-the-art technology and a wide range
of products have earned the company
a good position in the european steel
making industry and help it make good
use of its strategic location for serving
south Mediterranean markets.
this ePd is specifically about steel
bars and coils for concrete produced in
catania plant.
ThySSEN SONNENBERg RECyCLINg, in Bottrop, germany, is run
as a joint venture and has become one
of world’s leading companies producing
and selling ferrous and non-ferrous scrap
(www.tsr.eu).
FERROBERICA is the largest company
in italy involved in the pre-shaping and
laying of reinforcing steel for all kinds
of structural work, for roads, railway,
and maritime infrastructures, as well as
public, industrial and civil buildings. the
company handles the final stage of the
group’s production chain and guarantees
a high standard of quality for the end
users, i.e. leading building contractors.

2. thE product
hOT-ROLLED REINFORCINg STEEL FOR CONCRETE IN BARS AND COILS
this ePd refers to con-
struction products hot
rolled structural steel bars
and wire produced at Ac-
ciaierie di Sicilia plant
placed in catania (italy),
with electric arc furnace
route starting from post
and pre consumer steel
scraps. the homogeneous and repeatable mechanical
features of steel guarantee excellent performance in any
type of construction and geographical area, since they
have high ductility.
ePd reference products have a chemical composition in
compliance with national regulation of destination coun-
tries where they are sent. in general, the main materials
of the final product are: iron > 96%; alloy elements (e.g.
manganese, silicon, carbon) 2% c.a.; other elements (e.g..
copper, nickel, chromium), complementary to 100%.

methodology
the environmental burden of the prod-
uct has been calculated according to Pcr
icMQ-001/151 (rev. 0) construction prod-
ucts and construction services and en
15804:20142.
this declaration is a cradle to gate with
options ePd type, developed within the
ePditaly Programme and based on the
application of life cycle Assessment
(lcA) methodology3 to the whole life-cy-
cle system.
in the whole lcA model, infrastructures
and production equipments are not taken
into account.
Hot rolling steel bars at plant level, were
described by using specific data from
manufacturing facility (catania, italy)
for year 2014.
customized lcA questionnaires were
used to gather in-depth information about
all aspects of the production system (for
example, raw materials contents and
specifications, pre treatments, process ef-
ficiencies, air and water emissions, waste
management), in order to provide a com-
plete picture of the environmental burden
of the system from raw materials supply
(A1) to transport (A2) and Manufacturing
(A3).
the use phase and end of life were not
considered according to en:15804 and
Pcr 2012:01, while transport to final des-
tination was considered (A4).

from catania (in the South of italy) final products are delivered to many national (73% of the total sold product) and international areas such as Algeria (around 25%), Malta and tunisia.
the means of transport used to deliver steel bars and coils are truck and freight ship. on average, finished product is transported for 78 km by road and 313 km by ship.

the detailed environmental performance (in terms of use of resources, pollutant emissions and waste generation) is presented for the three phases, Upstream, core and
downstream and related sub-phases (A1-A2-A3-A4).
the numbers reported in the following tables are the outcome of rounding. for this reason total results could slightly differ from the sum of contributions of the different phases.

9. additional informationother environmental characteristics of acciaierie di sicilia plant are:
1. Acciaierie di Sicilia reinforcing steel in bars and coils production capacity is around
500,000 t per year. the main peculiarity is that ferrous scrap is mainly collected from
Sicily (about 90%).
2. in the recent years Acciaierie di Sicilia has committed to improve the environmental
performance of its production process with different measures, installing:
- a new off-gas filtering system in August 2010;
- a new suction hood, integrated with the installation of activated carbon input in feb-
ruary 2012.
Both systems guarantee enhanced environmental performance in terms of atmospher-
ic emissions: this new system has a filtering surface of 12,000 m2 and, with the inno-
vative impulse cleaning system, can achieve minimal emission levels, well below the
legal threshold.
3. Acciaierie di Sicilia has installed radiometric monitoring instruments (that use the
best available technology) to prevent radioactive-contaminated material or sources,
dispersed in the scrap or other materials, entering the factory.
the instruments are strategically positioned to monitor the entry of all the materials
used in the melting cycle and all other incoming materials. As well as monitoring of
the material on all incoming vehicles, the company carries out continuous in-process
monitoring by means of spectrometric analyses of the heat samples, thus guaranteeing
the absence of radiation contamination of the steel.
in accordance with general ePditaly requirements, the lcA study used specific, gener-
ic and other generic data. this last data are contributing to the environmental indicators
less than 10%.
