Possibility for Production of Biogas from Manure in Bulgaria

The permanent consumption increasing of energy, foods, techniques and other goods and serviced worldwide leads to the intensifier of their production and to the constant market expansion. In turn, the processes taking place in some of these productions are responsible for the deterioration of the quality of the environment. Over the last decade, science and industry have followed the environmental policies and one of the developing approaches is being the use of by-products as raw materials for new production. The waste to energy technologies meets the requirements both of sustainable managing of wastes and energy production by sources with zero carbon footprint. Typical for this technological approach is its local application and in this study is performed an overview analysis of the possibilities for utilization of livestock manures in systems for production of biogas in Bulgaria. Based on the statistical data for number, and type of farm animals in the country for 2020, their localization, and the potential for gas production of their manure, the calculations were made. The obtained results are presented by regional division and it was estimated that total 1142 installation with 500 kWh capacity could be realized in the investigated farms plants. The obtained results are promising and they are prerequisite for further technological and economic investigations of this waste to energy technology
