15 CONCLUSION pure manure plants are profitable according of Investment, methane/electricity and costs for manure plants on base of manure and energy crops are not profitable energy crops 40 per ton manure mist energy crops plants are profitable at 75 kwe according of Investment and methane/electricity manure mist plants are profitable at 50 or 75 kwe according of Investment and methane/electricity, perhaps a storage for digestate is not necessary
