Problems of environmental protection are nowadays one of the top priorities in a policy programme adopted by the European Community. Reducing the negative impact of the domestic foundry industry on environment should result from complex and long-lasting activities, targeted not only at modernisation of the dust collecting units, but also at searches and implementation of alternative, innovative and more pro-ecology oriented means and techniques of casting manufacture. Reducing to minimum the level of emissions escaping to the environment should be considered at all stages of the casting manufacturing process. In this study, the discussion was restricted to the process of the manufacture of moulds and cores for piece production of the heavy castings. The environmental impact of the technology of making moulds and cores in sands with chemical binders, used most often in piece production of large castings poured from iron alloys, was highlighted. As an alternative technology of mould preparation for the piece production of castings, the ecological and economic aspects of the full mould process were presented.
