The aim of the paper was an assessment of the effect of a commercial biopreparation, a liquid bacteria composite intended for improvement of biowaste processing efficiency, on the course of aerobic biostabilization process of the undersize fraction (waste separated from mixed municipal solid waste) mixed with municipal sewage sludge, as well as an assessment of the quality of initially obtained stabilized waste. Presented research comprised analyses of raw materials and mixtures used in the process and the waste obtained after 2 stage process (2 week intensive phase in a bioreactor and 6 week second phase - maturation in the compost pile). Moisture content, organic matter, C and N contents, C/N ratio and pH were analysed. Moreover, the number of parasites and microorganisms in waste was estimated. The process temperature was monitored. On the basis of conducted analyses it was stated that the biopreparation tested does not fulfil its basic role, so it should not be used in sewage sludge and municipal solid waste hygienization process. Physicochemical analysis indicated an insufficient progress in the properties of treatment waste. The number of all investigated microorganisms increased considerably after aerobic biostabilization process, despite the added biopreparation, which according to its manufacturer’s declaration was supposed to reveal antimicrobial effect. Moreover, presence of a large number of live parasite eggs was found in all analysed samples, which makes environmental application of the tested biowaste impossible.
