The results of the study regarding utilization of the waste gypsum formed as a by-product during the production of the magnesium sulphate from dolomite have been presented. The use of this waste have been proposed for the production of granulated multi-component fertilizers containing 25% N; 8% S; 14% CaO and 3.5% MgO. In the process of fertilizer production, the urea which will be bounded with the calcium and magnesium sulphate from the waste in the form of adducts of CaSO4 . 4CO(NH2)2 and MgSO4 . CO(NH2)2 . 3H2O will be the source of nitrogen in the fertilizer. It has been stated on the basis of the laboratory tests that the fertilizer with the assumed composition can be obtained by means of granulation of the raw material pulp, along with the dried and ground product return. The possibility of the production of the fertilizer with good physical properties according to the assumed concept has been confirmed in the pilot scale.

The results of investigations on a possible utilization of waste products formed during the production of commercial and food inorganic salts are presented. Application of wastes in the production of compound fertilizers was suggested. The work covered a full research cycle starting from laboratory tests and ending on the production implementation. Fertilizer formulas were developed on the basis of laboratory tests. A possible production of fertilizers of suggested compositions was tested on a pilot plant scale. The compound fertilizer production with the use of waste raw materials was implemented in Chemical Company Alwernia S.A. It reduced the amount of wastes directed to industrial waste site.

Przedstawiono wyniki badań nad możliwością zagospodarowania kilku produktów ubocznych przy produkcji nawozów wieloskładnikowych. Badania obejmowały pełny cykl, począwszy od badań laboratoryjnych a na wdrożeniu produkcji kończąc. W wyniku przeprowadzonych badań opracowano formuły nawozów, które można wytwarzać na bazie produktów ubocznych powstających w ZCh ALWERNIA SA. Wdrożenie produkcji nawozów wieloskładnikowych pozwoliło na zmniejszenie strumieni kierowanych na zakładowe składowisko odpadów.

Research results concerning the possibility to utalization a few by-products from the production of mulicomponent fertilizers were presented. Tests included the full cycle starting from laboratory tests and finishing on implementing the production. As a result of tests carried out fertilizers formulae possible to be produced on the basis of by-products coming from ZCh ALWERNIA SA are worked out. Implementing the production of mulicomponent fertilizers allowed to reduce streams pointed to the company landfill site.
