Possibility for Production of Biogas from Manure in Bulgaria

Abstract

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

Analysis of the overall potential for electricity production from farm animals manure in Bulgaria

“…Agriculture and animal husbandry are one of traditional and most important industries in the Bulgarian economy. Resent years trend is for increase in number of the farm animals [5]. Detail statistics for number of livestock and poultry in Bulgaria for year 2021 is available from Ministry of Agriculture and Foods of the Republic of Bulgaria [6][7].…”

“…The number of power plants using biogas as fuel in Europe is constantly increasing and more than a half of them are in Germany. Most of them are with electrical power between 100 kW and 500 kW [5]. There are 31 power plants with total electrical power of 38.7 MW using biogas as fuel in Bulgaria according to the Agency of Sustainable Energy Development register [4].…”
