Summary

To shape a common solution to challenges with low crop yields, proper protein supply and insufficient climate mitigation capacity, biorefining of protein feed from grassland crops for monogastric animals (including human) is introduced to the organic production system. Bio-refining using mechanical and natural fermentation techniques are compatible with the organic principles and standards. Crop yields from Danish field trials with alfalfa, clover and grass-clover mixtures demonstrate average yields around 12 tons dry matter per hectare yielding on average 700 kg extracted protein per hectare and 3000 to 6000 m3 methane per hectare. With these yields the profitability of biorefining of organic protein feed is calculated and shows a positive economic result, especially when used as wet-feed saving the cost for drying. But it should be noticed that economy is sensitive to changes in yields and prices.
