The article describes the quality parameters of the selected elements of biomass as a potential ecological biofuel. Several selected elements of a type of biomass were tested to determine the calorific value, humidity, content of sulfur and amount of ash produced in burning process. The concept of biomass and the legal aspects of its combustion are described. The research of biomass samples revealed that they may be turned into a high-energy, ecologically solid biofuel. Production of biofuel from the tested biomass does not require any additional binders. Studies have shown that the tested material can also act as a component of composite pellets. The quality parameters of such pellets can be determined with the composite calculator that is described in this article. The article also describes the technical aspects of the pellet production line, which should be applied to produce good-quality pellets from the tested types of biomass.
