AbstractThe paper presents the results of research aimed at evaluating the possibility of usingselected tree leaf species to produce solid biofuels. The possibility of production of qualitative solidbiofuels from urban tree leaves meets the expectations of the municipal sector. Collection of treeleaves in urban areas is very often necessary for road safety reasons, the need to collect biomass richin dust and pollution as well as biomass infested with pests. The production of solid biofuels fromtree leaves allows for effective management of this raw material with energy recovery. The performedresearch indicates such a possibility, and the obtained ash is used as a soil improver. The conductedresearch showed that the biomass of leaves of five tree species used in the experiment can be a sourceof raw materials for production of qualitative biofuels. The obtained pellets were characterized byproperties comparable to those of classical wood pellets. The lower heating value of the obtainedpellets ranged from 14.5 to 15.5 MJ·kg−1. Physical properties of the obtained pellets described bybulk density (BD 600–660 kg·m−3), mechanical durability (DU 90–96%), moisture (Mar10–12.5%)indicate that these products can be used in existing combustion equipment. Preliminary analysis ofthe obtained ashes (determination of ash melting point, bulk density) indicates that they should notcause difficulties in ash removal systems from the combustion chamber.
