Production of high protein supplementary feed from landfill gas

The article describes the problem of feed protein deficiency. The main sources of the methane for the biomass production are considered. The chemical composition, the haprin main characteristics and its production technological scheme are presented. The solid municipal waste volume disposed of annually at the landfills is estimated. The quantitative characteristics of atmospheric pollutant emissions from the JSC "Polygon" landfill (Vladimir region) are presented. It is proposed to use landfill gas as the main raw material in the haprin production. The haprin amount obtained during the operation of the JSC "Polygon" landfill was calculated. The economic benefits of this production were estimated © The Authors, published by EDP Sciences, 2020.
