The current publication summarizes the main results of the lignocellulosic biofuel research carried out within the project Sustainable Raw Material Management Thematic Network–RING 2017. In the first part of the paper, we explore the different type of currently available biomass residues potential and summarized for each Hungarian county. In the next part, we identify the main factors that significantly influence the sustainable raw material supply of a lignocellulosic biofuel production plant and investigate the additional feedstocks, which may be useable in the future. The results show a large amount of available biomass residues with more than 330 PJ energy potential. Particularly, the amount of generated agroresidues is outstanding, almost half of which can be used for energy production. However, the collection, storage and utilization for biofuel production of agroresidues is less developed than for woody material.
