REACH is an European Community regulation, which aims to improve the protection of human health and the environment from the risks that can be posed by chemicals. All chemical substances within the European Community (EC) territory in quantities of more than 1 Mg P.A. have to be registered by manufactures or importers, which have to submit to ECHA dossiers about each substance. The last mentioned refers to both natural as well as synthetic substances. Good example of this type of substances are zeolites. This paper presents the aspects of REACH regulation in case of zeolites production. Zeolites are crystalline, micro porous, hydrated aluminosilicates that are built from an infinitely extending three dimensional network of [SiO4]4- and [AlO4]5- tetrahedral linked to each other by the sharing of oxygen atoms. Zeolites, thanks to their sorptive and ion-exchange properties, have a great potential in their application e.g. water and wastewater treatment (removal of ammonium ions, heavy metals, oil-derivative contaminants, radioactive compounds), adsorption processes etc. Zeolites are natural minerals (chabazite, phillipsite, mordenite, clinoptilolite) but majority of zeolites used commercially are produced in synthetic processes. Natural zeolites are a substance within the meaning of REACH regulation as a consequence of mentioned substance definition given in 3rd Article of regulation. The problem of synthetic zeolites is closely connected with status of waste in the meaning of Waste Framework Directive and REACH regulation.
