This study aims to evaluate the feasibility of obtaining energy from waste biomass. The potential of waste biomass from aromatic plants, left after the production of essential oils, was assessed. The calorific value, ash content, volatile compounds, and moisture content were determined. Elemental analysis of the waste biomass was conducted to measure the C, H, N, and S contents. The results indicate that residual waste has significant potential as a quality feedstock for solid biofuel production. Compared to coal, the calculated emission factors demonstrate a reduction in CO and CO2 emissions by up to 30%, NOx by up to 80%, SO2 by up to 99%, and dust by up to 67%, depending on the waste used. When selecting suitable waste for energy production, it's essential to balance calorific value and emission factors. If energy efficiency is the priority, lavender, tansy, and thyme waste may be preferred. However, for sustainability and lower environmental impact, common sage waste could be the better choice. It's important to consider the specific context, including regulations and energy needs, when making a final decision.
