Waste management strategies such as anaerobic digestion and composting produce bio-based fertilizer products that could be applied to agricultural soil. Although multiple modelling software tools are available to simulate the environmental effect of fertilizer application to the soil, these models do not allow specification of emerging bio-based fertilizer types. Moreover, mathematical process models exist that allow optimizing the operational settings of waste management processes in order to produce an optimal bio-fertilizer quality adjusted to the local market needs. If an integrated tool would be available that couples process modelling to watershed modelling, the valorization chain could be simulated as a whole, i.e. the bio-fertilizer type and composition could be adjusted to the local watershed and environmental impacts of bio-based fertilizer production and application could more easily be assessed and controlled. The availability of such integrated tool may as such allow for improved decision and policy making regarding bio-fertilizer production and application with environmental benefits as a result.

整合资源回收过程和分水岭模型,以促进有关生物肥料生产和应用的决策

厌氧消化和堆肥等废物管理策略产生了可用于农业土壤的生物基肥料产品。尽管可以使用多种建模软件工具来模拟肥料对土壤的环境影响,但是这些模型不允许指定新兴的生物基肥料类型。而且,存在数学过程模型,该数学过程模型允许优化废物管理过程的操作设置,以便产生适应当地市场需求的最佳生物肥料质量。如果可以使用将流程建模与流域建模相结合的集成工具,则可以整体上评估价值链,即 可以根据当地分水岭调整生物肥料的类型和成分,更容易评估和控制生物基肥料生产和应用对环境的影响。这样的集成工具的可用性可以允许改进关于生物肥料生产和应用的决策和政策制定,从而具有环境效益。
