Sažetak (engleski)

The aim of this study was to analyse specific greenhouse gas emissions savings for a variety
of agricultural residues, industrial by-products, and municipal biowaste. One of the most viable
alternatives to fossil fuels is bioenergy, particularly biogas produced by the anaerobic digestion
of renewable feedstocks. The revised Renewable Energy Directive (D 2018/2001) recognizes that
biogas production from agricultural residues, livestock production, and industrial by-products is an
acknowledged greenhouse gas mitigation technology in cases where their use results in a certain level
of specific greenhouse gas savings. This study delivered values for the maximum transport distance
of agricultural residues and industrial by-products to achieve the greenhouse gas (GHG) emissionssaving requirement defined by Directive 2018/2001. It analysed the greenhouse gas emissions
reduction for numerous feedstocks for which Directive 2018/2001 has not defined the default and
typical values but which could be used as sustainable substitutes for currently dominantly used
maize silage in biogas production. The results obtained in this work define the maximum transport
and distribution distance for which biogas produced from considered feedstocks achieved required
specific greenhouse gas emissions savings (80%), compared with fossil fuel comparator. The obtained
results can be used as the constraints in the optimisation of the biomass supply chains for the
feedstocks considered in this work.
