Pyrolysis is considered as an effective and alternative way to treat organic waste and to obtain pyrolysis fuels as well as biochar. The latter may be used for different purposes in industry and agriculture, including use as a long term fertilizer. Biochar, after pyrolysis, is obtained in the form of powder; however from practical point of view it is better to use pelleted or granulated biochar since it significantly enhances biochar?s filed distribution. In our study we compared the efficacy of granulated and pow...

Woodchip material is one of the most promising fill media for denitrifying bioreactors. Woodchip denitrifying bioreactors are used for nitrate reduction in the outlets of drainage systems, shallow groundwaters, etc. Despite their overall positive effect, undesirable leaching of organic compounds from the fill medium can occur during a bioreactor?s start-up phase. The released organic compounds can cause oxygen depletion and some of them can have a toxic effect on biota. The paper presents the quality of leachates ...
