Abstract

Added energy value from application of fish industry co-streams for biogas production and use of substrates for soil fertilising is discussed in the paper.
The analysis of added value of fish co-streams was done by comparing two different scenarios. Scenario 1 represents the system of the fertilisation of arable land intended for summer barley growing and Scenario 2 – arable land is fertilised with a digestate of mixture of fish co-streams and cattle manure after anaerobic digestion.
The farm system corresponding 600 milking cows producing 12000 t/year of manure having 600 ha of cultivated land has been used and the mass of fish waste is estimated to be 2400 t per year.
The energetic evaluation has been performed including direct and indirect energy inputs for all technological operations and processes.
Results of the study suggest that fish waste used for biogas production and soil fertilization generates additional energy value for the farm.
