- Most of used mineral and organic sorbents are hazardous waste and, therefore, in accordance with actual law regulations must be converted thermally or deposited in the special landfill for hazardous waste. Up to now both methods are expensive and burning methods are still watch as a controversial method . The optimal solution would be sorption materials that could be used repeatedly, without the need for costly and cumbersome lanfilling. Sorbents, which due to their properties could be used repeatedly, are MSW composts generated from mixed or only organic municipal waste. In this study we have investigated the rate of degradation of motor oil on MSW waste composts from two different technologies. Comparison of degradation efficiency, was calculated in comparison to the commercial sorbents. As sorbents were used organic (Peatsorb) and mineral (EcoDryPlus) materials which are in common use and available on the market. Both commercial sorbents were different in case of pH value and amount of biogenic elements and organic matter. Composts used in experiment also were characterized with high EC value, what could be a factor of microbial activity inhibition. During the experiment the total amount of standard diesel oil available on every petrol station and individual n-alkanes with carbon chain length from C8 to C19 was determinate. For comparison additionally was determined content of C20 and C21 n-alkanes. During the experiment, there were observed more intensive oil degradation processes on waste composts in comparison to commercial sorbents. Microflora which use n-alkanes as a carbon source, ensured quick (noted after 22 days of the experiment), reduction of the amount of hydrocarbons contamination in the samples, and thus the possibility of re-use of compost as a sorbent. The observed rapid degradation process, indicates the direction of the recovery of compost waste, used previously as a sorbent for the removal of petroleum contaminants (diesel oil). Undoubtedly, this is a cheaper way than the thermal incineration or storage.
