Agricultural biomass has great bioenergy potential due to its availability, and it is a carbon-free energy source. During biomass incineration, biomass ash is formed, which is still considered as a waste without proper disposal and management solutions. Various biomass ash utilization options were investigated, mainly concerning engineering issues (the mechanical characterization of newly produced building materials or products), and there is a lack of knowledge of environmental issues arising from this "waste" material utilization in civil engineering practice. The main aim of this research is discussion of a different agricultural biomass characteristics as a fuel, the impact of agricultural biomass ashes (ABA) on the mechanical properties of stabilized soil with a particular emphasis on the environmental impacts within this kind of waste management. The results of this study indicate improved geotechnical characteristics of low-plasticity clay stabilized by lime/ABA binder. In addition to mechanical characterization for materials embedded in road embankments and subgrades, appropriate environmental risk assessment needs to be performed, and the results of this study indicate that the amount of ABAs added to the soil for roadworks should not have adverse effects on the soil fauna in the surrounding environment.
由于农业生物质的可得性，它具有巨大的生物能源潜力，并且是一种无碳能源。在生物质焚烧过程中会形成生物质灰，在没有适当处置和管理解决方案的情况下，它仍被视为一种废物。对各种生物质灰的利用选项进行了研究，主要涉及工程问题（新生产的建筑材料或产品的力学特性），而对于土木工程实践中这种“废物”材料利用所产生的环境问题缺乏了解。本研究的主要目的是讨论作为燃料的不同农业生物质特性、农业生物质灰（ABA）对稳定土力学性能的影响，并特别强调这类废物管理中的环境影响。本研究结果表明，用石灰/ABA粘结剂稳定的低塑性粘土的岩土特性得到了改善。除了对路堤和路基中材料的力学特性进行表征外，还需要进行适当的环境风险评估，本研究结果表明，道路工程中添加到土壤中的ABA量不应对周围环境中的土壤动物群产生不利影响。
