When gas is cleaned in the process of slow pyrolysis in small-scale applications, water scrubbing is the most commonly used technology. After gas cleaning the tar and water vapors are trapped in the water, which is used for scrubbing. This waste water consists of condensed water vapoEndurnýjanleg orkars and two fractions of tar (water soluble and heavy tar). The product of this slow pyrolysis process is considered waste. None of the tar fractions are adequate for direct use in co-firing technologies. First it (water soluble tar fraction) contains too much water and later in the heavy tar there is not a sufficient quantity. The percentage of tar yielded from the slow pyrolysis process is not sufficient to be distilled in order to chemically clean components for further industry use, but that is the case in fast pyrolysis. That is why it is treated as chemical waste and needs to be disposed properly, which is a costly process. In order to reduce this cost a bioremediation method of fungi tar degradation has been examined. Fungi have a more potent enzyme system and are therefore far more appropriate for tar degradation than bacteria.
