Green cut material is a potential source of renewable energy which is not fully exploited through conventional energy recovery systems. A new energy conversion process, the integrated generation of solid fuel and biogas from biomass (IFBB), which includes mechanical separation after hydro-thermal conditioning, was investigated. Ash softening temperature and lower heating value of the solid fuel were increased through the IFFB process in comparison to the untreated raw material. The net energy yield of IFBB at 40 °C conditioning temperature ranged between 1.96 and 2.85 kWh kg(-1) dry matter (DM) and for the direct combustion between 1.75 and 2.65 kWh kg(-1) DM. Conversion efficiencies for the IFBB system were 0.42-0.68 and for direct combustion 0.42-0.63. The IFBB system produces storable energy from material which is nowadays not used for energy conversion.
绿色切割材料是一种可再生能源的潜在来源，但尚未通过传统的能源回收系统得到充分利用。本研究开发了一种新的能源转换工艺，即生物质的固体燃料和沼气综合生成（IFBB），该工艺包括水热处理后的机械分离。与未经处理的原料相比，IFFB 工艺提高了固体燃料的灰软化温度和低位热值。在 40°C 调理温度下，IFBB 的净能量产率在 1.96 和 2.85 kWh kg(-1)干物质（DM）之间，而直接燃烧的净能量产率在 1.75 和 2.65 kWh kg(-1) DM 之间。IFBB 系统的转换效率为 0.42-0.68，直接燃烧的转换效率为 0.42-0.63。IFBB 系统可以从目前未用于能源转换的材料中产生可储存的能源。
