Assessment of the technical potential of agricultural and industrial residues and by-products for bioenergy use

Bioenergy can be produced from a range of feedstocks and utilised for production of renewable electricity, thermal energy or transportation fuels. Using feedstocks that have been grown on agricultural land has caused concerns over the negative environmental impact due to indirect land use change. Consequently, feedstocks such as agricultural and industrial residues and by-products are receiving increasing policy support from the European Union. The main objective of this work is to elaborate a method for assessment of the technical potential of available agricultural and industrial residues and by-products for bioenergy production. This method takes into account residues and by-products which occurs during the three stages from farm to table: food production, processing stage and human consumption. Those stages were analysed for five sectors: fruits, vegetables, cereals, industrial crops and animals. When estimating the potential of available residues and by- products, the residue-to- product ratios were used. In order to quantify the technical potential of mentioned feedstocks, their current use was subtracted from the total available amount. Spatial distribution was also taken into account, by calculating the technical potential of residues and by-products for the NUTS-3 regions. The presented method is demonstrated on the case study for the Republic of Croatia. The technical potential for all of the residues and by-products that appears in above-mentioned sectors are calculated and graphically shown for each of the 21 NUTS-3 regions. Technical potential varies significantly between the regions, putting those regions with higher technical potential in the position to be more suitable for installing bioenergy production entity.
