In recent years, the area sown with lavender has increased in Bulgaria, which is then processed to essential oils by steam distillation. Plant residues after the steam distillation process are a major environmental problem and, at the same time, a valuable source of biofuels. Thus, the processing of lavender waste solves the problem of environmental pollution and generates energy that can be used for various purposes. This paper analyzes the possibilities for obtaining energy from lavender biomass. The processes of direct combustion and pyrolysis with their advantages and disadvantages are analysed and the yields of the obtained products are predicted by analytical calculations. For the purposes of this study, an experiment was conducted to determine the pyrolysis products of lavender straws and their quantitative ratios, which were compared with analytical calculations. The results show that the energy obtained can ensure the implementation of the steam distillation process and the residual energy can be used for other purposes.
