Sažetak
Biogas production through anaerobic digestion technology offers numerous benefits as it may not onlyrecover a part of the energy contained in the biomass but also contributes to circular economy targets.Concerns about biogas production from feed and food crops raise the need for the assessment of biogaspotential produced out of biomass, which is not in competition with the other purposes, such as potentialof industrial residuals and by- products. This research presents the approach for the assessment of biogaspotential from industrial residues and by-products, by taking into consideration spatial and seasonalvariation of feedstock production. In this work, considered feedstocks are those which occur in sugar, wine, vegetable and olive oil industries. This approach was tested through the case study of two Croatiancounties. The results are presenting the spatial distribution and seasonal variation of the biogas potentialfrom residues and by-products of considered industries. The results proved the hypothesis that there is astrong need to include a seasonal aspect when defining the biomass potential viable for biogas pro-duction, due to the low annual load factor calculated for potential biogas sites, which range from 0.1 to0.24 for the case when feedstock storage is not available.
