Table 6 Composition and net calorific values of biomass from rushes compared to other common biomass-based fuels

From: The energy potential of soft rush (Juncus effusus L.) in different conversion routes

Kind of biomass Crude ash (% DM) Volatile matter (% oDM) C-fix (% oDM) Hi(wf) (MJ kg DM−1) Hi (MJ kg FMw15−1) Hi (kWh kg FMw15–1)
