| The addition of a biorefinery to an organic farm was investigated, where ethanol was produced from germinated rye grains and whey, and the effluent was separated into two streams: the protein-rich solid fraction, to be used as animal feed, and the liquid fraction, which can be co-digested with clover grass silage to produce biogas. A method for ethanol production from rye was applied by utilizing inherent amylase activity from germination of the seed. Biogas potential of ethanol fermentation effluent was measured through anaerobic digestion trials. The effluent from the trials was assumed to serve as natural fertilizer. A technoeconomic analysis was also performed; total capital investment was estimated to be approximately 4 M USD. Setting a methane... |

| The organic farming community has long been recognized for its environmental awareness and has been seeking ways to reduce greenhouse gas emissions and become energy independent. In that regard, ethanol can substitute a fraction of the gasoline used by farming equipment, whereas biogas can fuel the production of heat and electricity for the farm. We investigated the addition of a biorefinery to an organic farm, where ethanol was produced from germinated rye grains and whey and the effluent was separated into two streams: the protein-rich solid fraction, to be used as animal feed, and the liquid fraction, which can be co-digested with clover grass silage to produce biogas. The effluent from the anaerobic digestion process was assumed to serve as natural... |
