FOSSIL FUELS CONSUMPTION EVALUATION IN BLAST FURNACE TECHNOLOGY BASED ON DIFFERENT LIFE CYCLE IMPACT ASSESSMENT METHODS

Non-renewable resources management is one of the key issues of sustainable development. Therefore it is important to implement methods for assessing of the materials and fuels use in industrial processes. In this paper evaluation of fossil fuels consumption in blast furnace technology based on different life cycle impact assessment methods was presented. In order to evaluate the consumption of resources was used four life cycle impacts assessment methods: Ecoindicator 99, Cumulative Energy Demand, Cumulative Exergy Demand and ReCiPe. Different scenarios of using waste plastics as alternative fuels to reduce consumption of fossil fuels was presented. Life Cycle Assessment (LCA) analysis was carried out in accordance with standard EN ISO 14040: 2006, by four phase: goal and scope definition of LCA, inventory analysis LCI (Life Cycle Inventory), impact assessment LCIA (Life Cycle Impact Assessment) and interpretation. In order to perform LCA analysis was used SimaPro 7.3 software.
