3 COMPANY PROFILE The Feralpi Group is one of Europe s leading manufacturers of steels for use in building construction. The parent company Feralpi Siderurgica, which was set up in 1968 in Lonato del Garda, near Brescia, has developed steadily over the years to form a group of industries that currently more than two million tonnes of steel and rolled products a year, and has a workforce of 15 permanent employees in Italy, Europe and North Africa. In over forty years of business, the company has branched out to foreign markets and have been able to face the challenge of an increasingly globalized steel industry. Starting from its lengthy tradition in steel manufacturing, the Group has developed according to a strategy of diversification into new products and markets, which has involved not only the internal organisation but also external transactions thanks to the acquisition of numerous enterprises operating in this industry. The Feralpi Group also operates in the field of special steels, cold working, structural steelwork, the environment and fish farming, not to mention financial activities and investments. Since its very origins, Feralpi has focused not only on producing the best steel grades for building construction but also on doing it in the most sustainable possible way, which has involved reducing energy consumption and emissions by using the latest technology available or developing inhouse new solutions covered by patents as a result of intensive innovation and research. Feralpi, an international diversified group (217) million tons 2.89 million tons 799,137 tons 1,199 million euros 64% 1, million euros Steel production Hot rolled production Cold rolled productis and derivatives Turnover Turnover abroad Employees (216) Technical investments 3

5 THE PRODUCT Rebar is the core of reinforced steel structures. Ribs provide improved adherence to the concrete. Special chemical analysis and a monitored production process give the rebar excellent mechanical properties for use in severe or harsh applications, requiring a high standard of safety for private and industrial buildings and large motorway, railway and airport infrastructures. Thanks to its ductility properties, Feralpi reinforcing steel in bar complies fully with antiseismic requirements. Declared unit for the study is one tonne of hot rolled products.

6 ENVIRONMENTAL PERFORMANCE 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 subphases (A1A2A3A4). 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 CALCULATION RULES The environmental burden of the product has been calculated according to EN 1584:214 and PCR ICMQ1/15 rev. This declaration is a cradle to gate with options EPD type, based on the application of Life Cycle Assessment (LCA) methodology to the whole lifecycle system. In the whole LCA model, infrastructures and production equipments are not taken into account. Hot rolled steel bars at plant level were described by using specific data from manufacturing facility (Lonato del Garda, BS, Italy) for year 217. Customized LCA questionnaires were used to gather indepth information about all aspects of the production system (for example, raw materials contents and specifications, pre treatments, process efficiencies, air and water emissions, waste management), in order to provide a complete 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:1584 andpcr ICMQ 1/15 rev, while transport to final destination was considered (A4). According to ISO 144 and 1444, allocation is avoided whenever possible by dividing the system into subsystems. When allocation cannot be avoided physical properties are used to drive flow analysis. Data quality has been assessed and validated during data collection process. According to EN:1584 the applied cutoff criterion for mass and energy flows is 1%. 9

From Lonato (northern Italy) final products are delivered to many national (49% of the total sold product) and international areas such as Algeria (around 6%), France and Switzerland, mentioning the main countries. The means of transport used to deliver steel bars and coils are truck and freight ship. On average, hot rolled products are transported for 297 km by road and km by ship. A4 Distribution 13
