Abstract: This thesis is a part of a leather wastewater management project, carried out by the company TEKNOLOGIAKESKUS KETEK Oy. The aim of the project is to find out effective treatments of the sludge coming out of tanneries' wastewater treatment plant. This thesis investigates the feasibility of using high chromium content tannery sludge as feed for a biogas plant. \n \nThe method used to treat sludge in this thesis is anaerobic digestion. All analysis and lab-scale digestions were carried out in reference to the Finnish SFS standards. Besides, the target plant which might be able to treat the sludge, all the cost for transporting and bringing the sludge to the target biogas plant, as well as the legislative issues were taken into account. \n \nIt was proven that treating the sludge by anaerobic digestion is technically and economically feasible, but the legislative barriers are still difficult to cover. Therefore, further investigation are required in order to solve the problem of high metal concentration in the sludge sustainably.
