Bioethanol Production Potential and Other Biomass Energy Properties of Invasive Reynoutria, Solidago, and Spiraea Plants

Due to the threat posed by spread of invasive plant species, there is an urgent need develop effective methods eradicating and managing their biomass. The aim study was examine selected plants in terms use for energy purposes find out whether they can be a raw material production second-generation biofuels. First, chemical compositions were determined. higher heating value (HHV) lower (LHV) also calculated. High values value, ranging from 18.490 MJ∙kg−1 19.900 MJ∙kg−1, indicate possibility using biomass (combustion). All investigated species subjected process obtaining ethanol. This included alkaline pretreatment with 1% sodium hydroxide, followed simultaneous saccharification fermentation (SSF) process. highest ethanol yield per ha obtained at 2.6 m3∙ha−1 Reynoutria × bohemica remaining showed below 2 m3∙ha−1. conducted research allows conclusion that studied promising bioethanol.
