Podmínky a možnosti využití odpadních materiálů pro rekultivace území.

Abstract

The aim of this thesis is to choose convenient improvement material as a mixture of available industrial waste materials. The waste materials are produced by metallurgical and chemical industry and power engineering. There was chosen always one “example material” produced by each of above-mentioned industry. Regarding to the specific physical and chemical conditions the improvement material must be in compliance with then, as the first step, there were chosen waste materials mixed in a laboratory owned by OKD, Doprava, akciová společnost in Ostrava Zárubek. Then, as the following step, there were, out of already prepared mixtures, chosen four samples with different mixing ratio and their physical features were tested during operational test. Then, there were chosen only two out of four original samples that underwent chemical analysis and the analysis results were compared with limits specified in valid legislation 294/2005 Sb., Annex 10 and 12. Above-mentioned process was used for choosing the most convenient mixture of waste materials that would be suitable for recultivation. The only mixture of waste materials that is in compliance with predefined conditions is the one consisting of Prestab and stabilized ash with mixing ratio 1:1,5.
