This contribution deals with those aspects of the application of natural microporous materials (NMM), which are projected for a millennial horizon of environmental protection. Thought the NMM possess excellent sorption properties, their natural physico-mechanical form usually limits their application in technological processes, such as packed-bed columns. However, due to their thermal and radiation stability, compressive strength, steadiness towards the freezing/ thawing and wetting/ drying cycles, they have received increasing interest in the long-term hazardous waste treatment both in situ and plant performance. To improve mechanical properties of crystals, solid carriers such as cellulose and carbon, or binders such as organic polymers, are applied. Artificial formation of composities and both inorganic and organic complexes of NMM is applied for: (1) field barriers (mortars and grouts), (2) reagents and organic coating supports, (3) granules, pellets and column packings, (4) additives to cementitious fixation matrices, and (5) ceramics and glass formulations.
