As part of a comprehensive evaluation of the use of Sida hermaphrodita (hereafter referred to as Sida) biomass as a solid biofuel, a life cycle assessment (LCA) according to ISO 14040/14044 was carried out by means of a suitable cradle-to-gate system design. The supply and use of chips, pellets and briquettes was studied by internal and external comparisons to show competitiveness and improvement options. The results show fewer differences within the Sida process chain designs but larger distinctions to compared alternative biofuels such as wood or Miscanthus pellets. A major finding is that Sida process chains cause lower environmental impacts in comparison with alternative biofuels. The study identified hot spots within the Sida process chains and starting points for further improvement. A sensitivity analysis of important parameters, such as specific yield or heating values was performed. Because there are no similar investigations on the environmental impact of Sida used as a biogenic solid fuel to date this manuscript presents first results. So far, the results indicate that Sida provides a more sustainable option for the use of biomass in combustion processes in relation to environmental impacts.

作为使用Sida hermaphrodita（以下简称Sida）生物质作为固体生物燃料的综合评估的一部分，根据ISO 14040/14044进行了生命周期评估（LCA）。门系统设计。通过内部和外部比较研究了切片，颗粒和团块的供应和使用，以显示竞争力和改进方案。结果表明，Sida工艺链设计中的差异较小，但与木材或芒草等替代生物燃料相比，差异更大颗粒。一个主要发现是，与替代性生物燃料相比，Sida工艺链对环境的影响较小。该研究确定了Sida工艺链中的热点和进一步改进的起点。对重要参数（例如比产率或发热量）进行了敏感性分析。迄今为止，由于尚未有关于将Sida用作生物固体燃料的环境影响的类似研究，因此该论文提出了初步结果。到目前为止，结果表明，Sida为燃烧过程中与环境影响相关的生物质的使用提供了一种更可持续的选择。
