This paper presents the results of research which is part of studies carried out under the project POIG.01.01.02-00-015/09 "Advanced Materials and Technologies", one of the aims of which is to introduce new, environment-friendly, inorganic binders to the production of castings from non-ferrous metals. The paper presents the results of research on the management of waste moulding sands prepared according to the new technology, including their multiple reclamation and management of post-reclamation waste. Studies of multiple reclamation are a continuation of the preliminary research described earlier. The programme of the studies described in this paper also included validation of the results under industrial conditions.

One of the factors that contribute to the development of foundry moulding technology is environmental protection. The related challenges are effectively satisfied by a new inorganic binder that has been designed for castings made of non-ferrous metal alloys. This article presents in a concise way the test results, showing the ecological character of the new binder at the stage of making moulds, pouring them with metal and cooling of castings, indicating the possibilities for an economic re-use of waste materials formed during practical application of this technology. The results were compared with the results obtained on the sands with organic binders. Studies were carried out under the project POIG.01.01.02-00-015/09 "Advanced materials and technologies."
