Different vegetable waste materials (beetroot leaves, turnip leaves, yellow beans, onion waste), commonly found in Central Poland were tested for estimation of energy efficiency while methane fermentation process. The results showed that the biggest green mass of vegetable waste harvested from field was related to the highest water content. In contrary, the higher methane production from 1 Mg of tested biowaste was obtained in case of the materials with the highest dry mass content (yellow beans and onion waste, 28.03 and 44.33 m3 Mg-1). Although the onion waste was the lowest fermented substrate, however the energy yield for this material is visibly the highest (4435 kWh ha-1) among all tested ones.
