The paper gives an insight into the possibilities to use Latvian mineral raw materials as a base or additives for the development of ceramic materials (ecomaterials) with different application aspects, including showing the possibility of optimizing the technological processes of these materials towards the reduction of their firing temperature, thereby reducing the release of harmful gaseous effluents into the environment. The results of the works that are reported in the period were obtained from 2007 to 2017. The following studies are reviewed and analyzed: the use of untreated clay for the sealing of waste deposits; the use of partly dehydrated clay for sorption of Cr3+,6+, Zn2+ a nd C u2+, which have formed in galvanic processes; the development of porous high temperature ceramics from mixes of mineral raw materials and synthetic additives that provide a sufficient gas phase formation in the firing process and consecutively to form pores in obtained ceramic material; the use of illite clay additives to reduce the temperature of sintering of high temperature dense mechanical and thermally durable ceramics, as well as technological processes that ensure the production of porous, heat-insulating ceramic materials at reduced temperatures (geopolymer method).
