Industrial production of any contemporary product could be organized according to the requirements of environmental protection and capability of sustainable development of national economics. Contemporary aspects of development strategy of any country are rational and thrifty utilization of natural resources, application of waste less technologies in the limits of capability. Both industrial as well domestic wastes is possible to apply skilfully in order to create new materials. Among the broad range of inorganic mineral raw materials, used in Latvian national economy, clay of different geological origin, sand and gravel of different composition, as well the limestone, dolomite and gypsum could be outlined. The range of known inorganic industrial waste is relatively broad: metallurgical slag and waste of metal processing residues, multialkali glass, etching refuse, electro filter dust, furnace ash, and the remnants of burned domestic waste. In Germany and Sweden the domestic waste is industrially incinerated in high temperature furnaces, the obtained thermal energy is utilized in municipal household, but the inorganic remains – deposited. It is time for application both of existing natural resources as well as the recyclable materials in a skilful way. Research carried out by us have proved it: the chemical and mineralogical composition as well the thermal properties of industrial waste mentioned above have been detected, and different compositions for glass-ceramic materials elaborated, in order to apply them for the replacement of natural rocks and minerals. Several methods for the elaboration of glass-ceramics have been developed. By applying powder technology and one-step thermal treatment until 1400o C, composite materials have been obtained, with the chemical and physical properties corresponding to inert glass-ceramic materials. The aim of mentioned studies is to obtain materials applicable for second time, useful for domestical, industrial or civil engineering purposes: finishing tiles for interior and floor, building or decoration materials or road covering. According to the tested functional properties of the obtained materials, they correspond to the criterions defined in the building material standards of Latvian State.
