Abstract

Different operations, such as fleshing, trimmings, cuttings and chips from hides, causes leather industry in being one of the most environmental пїЅunfriendlyпїЅ sectors. Moreover, the treatment of sewage waters brings up also the problem of mud which is related with the appearance of biodegradation process of organic waste, followed by the emission of greenhouse gases, especially methane and nitrous oxide. All these wastes also imply a terrible smell and a strong land contamination. The large quantity of wastes, but also their variety led to a continuous process of developing new ways to treat and solve these problems by their recovery technically, economically and environmentally. In order to follow the general trend of energy recovery and the possibility of using in the system, there are distinguished two options: animal fat and biogas resulted from wastewater treatment and sludge discharged. One of the most favorable technological solution is the anaerobic digestion that decomposes a part of the organic matter contained in the tannery sludge and solid waste, by biogas production.
