Biogas resources in industrial production of pork

Abstract

The article analyzes the use of renewable sources of energy – biogas in the European Union and Ukraine. It is shown that the agro-industrial sector of Ukraine, producing a significant amount of organic waste, potentially has the resources to produce biogas and can replace 2.6 bln m3 PG/year. The contribution of organic waste in industrial production of pork can be 0.32 Mt of fuel. The authors believe that the main barrier to the implementation of bioenergy systems in industrial production of pork in Ukraine are large capital investments and operating costs as well as suboptimal substrate for fermentation parameters. Strategieses to ensure the reduction of capital investment and implementation of technologies of using sewages from the industrial production of pork to obtain renewable energy should be promoted more strongly. The technological process includes separating sewage, sediment compaction, resulting in a thin layer of its subsequent methane fermentation to produce biogas, electricity and heat. It is shown that the proposed approach can reduce capital investment at 30%.
