ABOUT THE EPDThis Environmental Product Declaration (EPD) contains the realfacts from a Life Cycle Assessment (LCA) and provides informationthat can be used in order to put into perspective differentsteel 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 solutionsthat affects the total environmental impact of its products.Celsa Steel Service AB is certified according to ISO 14001, andworks for a sustainable development of the environment. Thisdedication motivates a quest to minimize material and energyuse, but also to seek possibilities to increase the efficiency and reduceheavy work and unhealthy environments for people workingwith reinforcement. The company, as a part of CELSA Group,has the safety as the first priority and the company has incorporatedsafety in all its daily activities.For the products delivered by Celsa Steel Service, the upstreamprocesses that include the scrap processing and the steelworks is the dominating emitter. Apart from the upstream processes,the environmental burden is dependent on transportationdistances, efficient logistics, the level of prefabricationwith minimum material use, and efficient installation at theconstruction site. Construction sites have the potential to bemore sustainable by limiting the number transports, handle materialsmore efficiently, and implement routines to reduce wastes.Material for the production of reinforcement steel comes fromthe group’s steel and rolling mill in Mo i Rana, Norway. Celsa Nordichas during many years invested in new technology, not only toconform to, but to exceed environmental demands in Norwegianlegislation. All these investments have together a major impactin the production of more environmentally friendly reinforcementsteels 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 millin northern Norway. The use of hydropower reduces indirect emissionsand the water used in the processes is naturally sourcedfrom immediate surrounding water magazines without any energyinput for retrieving it. The water is available in the processesbut is also generating electricity in the industrial park beforereaching sea level.Celsa Nordic has been an environmental pioneer in Norway by:• Producing its first environmental report according to NS-ENISO 14001 already in 1996• Becoming one of the first mills in Europe to get the EMAS markin 2010.• A 100 % scrap based production, being the largest recyclingcompany in Norway.• Reducing mercury emissions as well as primary and secondarydust emissions, recognized by the Norwegian Climate andPollution Agency (Klif).“We take into account the environmental,social and economic consequences of the strategicdecisions we make in all our daily tasks”Celsa Steel Service – EPD – SWE3

It isdue to emissions of SO 2, NO xand NH 3, which are therefore includedin the Acidification Potential (AP) indicator, expressed asSO 2-eq.Ozone depletiondegradation of the stratospheric ozone layer, which blocks theultra-violet component of sunlight, by means of highly reactivecompounds originating from chlorofluorocarbons (CFCs) or chlorofluoromethanes(CFMs). The substance used as a reference forthe ODP (Ozone-Depletion Poten-tial) is trichlorofluoromethane,or CFC-11.Greenhouse effecta phenomenon whereby infra-red rays emitted by the earth’s surfacefollowing solar heating are absorbed by molecules present inthe atmosphere and reemitted in the form of heat, causing globalwarming 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 higherdegree of infra-red absorption, such as methane (CH 4), nitrousgas (N 2O) and chlorofluorocarbons (CFCs), which are expressedas a function of the degree of absorption of CO 2(g CO 2).Eutrophicationthe enrichment of watercourses with nutrients, which causes imbalancesin aquatic ecosystems due to overdevelopment as theresult of a lack of nutritional limitations. Eutrophication Potential(EP) mainly covers phosphorous and nitrogen salts, and is expressedas PO 43-eq.Photochemical ozone creationthe production of compounds which, by the action of light, areable to promote an oxidation reaction that leads to the productionof ozone in the troposphere. The POCP (Photochemical OzoneCreation Potential) indicator mainly concerns VOCs (Volatile OrganicCompounds) and is expressed as equivalent weight of ethylene(g C 2H 4).Next generationswill bene fit fromtoday’s responsibleconsumptionCO 2countsCelsa Steel Service – EPD – SWE8
