Tiivistelmä
The purpose of this thesis was to evaluate the economic value of manure in the Ostrobothnia region. The study starts with the introduction of manure management concept and discusses the importance of it. Then the aspect of manure as a fertilizer is
explored as well as the value addition chain which involves processing it using aerobic co-digestion.
The next part deals with specific data regarding manure in Ostrobothnia. The data contains the number of livestock according to breed and the manure production with their respective nutrient content and biogas potential. This is followed by mathematical
models for evaluating the manure value in different scenarios.
First scenario is using the manure as a fertilizer without any treatment. In this case, the value is compared to commercial fertilizer even though the nutrient solubility rate is
low. The other scenario is using anaerobic digestion to treat the manure before using the digestate as fertilizer. This has multiple benefits including improving the soluble nitrogen, renewable energy production and emission savings.
