Evaluation of Invasive Herbaceous Plants Utilization for the Production of Pressed Biofuel

The present article focuses on pressed biofuel preparation from invasive herbaceous plants, and the quality indicators properties were analyzed determined. Two plants chosen for this research: giant knotweed (Fallopia sachalinensis) Sosnowsky’s hogweed (Heracleum sosnowskyi). For a control, pine wood biomass was utilized. After harvesting drying, plant chopped milled later into cylindrical pellets briquettes. research results pellets’ briquettes’ physical elemental showed that density of (moisture 5–8%) reached 1145.60–1227.47 kg m−3, average briquettes 615.60–867.31 m−3. determined critical compressive strength ranged 420 N to 676 N, disintegrated under significantly greater force 783 1219 N. variation in pellet with changes their moisture content also investigated. lower caloric value varied 15.9 MJ kg−1 18.6 kg−1. Harmful gas emissions during burning tested evaluated determined, they sufficiently low did not exceed permissible values. Finally, it can be stated all biofuels produced met most important requirements solid used special boilers.
