This submission deals with an identifications od environmental aspects and their
environmental assessment of gray cast iron foundry operations using the LCA method, with emphasis on the use of waste materials. Casting with its outputs has a significant impact on the environment. This type of industry is dependent on the amount of natural resources, raw materials and energy that are consumed and used. Method of Life Cycle Assessment (LCA), is one of the management techniques. For this method are created a series of standards ISO 14040:2006 and ISO 14044:2006. Foundry is a typical ferrous metal foundry with a production capacity exceeding 20 tones/day. System boundaries shall be as set gate to gate. The overall results of the impact assessment gives an overview of the overall environmental impact of the production of 1 ton casting of gray and ductile iron. These results show that the greatest impact on the desired category and group impacts have processes associated with melting of metals on the opinion melting shop and 64.59%. This effect is mainly due to the intensity of the main extraction and processing of raw materials. Important role and contribution of foundry Hronec is its action-recovery of scrap metal. Recovery of scrap metal in the melting process 1 t casting represents mitigate smelter by 49.6%, thus foundry Hronec contributes significantly to saving so demanding entry, such as pig iron. With this contribution we are highlighting the factors that most contribute to the burden pos. Unit processes in the foundry production are the main contributors to the
consumption of resources. This research may serve as the basis for further research on the impact of foundry industry on the environment.
