This paper aims to develop a generic roadmap for setting up strategies for nutrient recovery from digested waste (digestate). First, a guideline-based decision-tree is presented for setting up an optimal bio-based fertilization strategy as function of local agronomic and regulatory criteria. Next, guidelines and evaluation criteria are provided to determine the feasibility of bio-based fertilizer production as function of the input digestate characteristics. Finally, a conceptual decision making algorithm is developed aiming at the configuration and optimization of nutrient recovery treatment trains. Important input digestate characteristics to measure, and essential factors for monitoring and control are identified. As such, this paper provides a useful decision-support guide for wastewater and residuals processing utilities aiming to implement nutrient recovery strategies. This, in turn, may stimulate and hasten the global transition from wastewater treatment plants to water resource recovery facilities. On top of that, the proposed roadmap may help adjusting the choice of nutrient recovery strategies to local fertilizer markets, thereby speeding up the transition from a fossil-reserve based to a bio-based circular nutrient economy.
本文旨在制定一个通用路线图，用于制定从消化废物（沼渣）中回收养分的策略。首先，提出了一种基于指南的决策树，用于根据当地农艺和监管标准制定最佳生物基施肥策略。其次，提供了指南和评估标准，以确定根据输入沼渣特性生产生物基肥料的可行性。最后，开发了一种概念性决策算法，旨在配置和优化养分回收处理流程。确定了需要测量的重要沼渣特性输入，以及监测和控制的关键因素。因此，本文为旨在实施养分回收策略的废水和残渣处理设施提供了有用的决策支持指南。这反过来可能会刺激并加速从污水处理厂向水资源回收设施的全球转型。除此之外，所提出的路线图可能有助于根据当地肥料市场调整养分回收策略的选择，从而加速从基于化石储备的经济向基于生物基的循环养分经济的转型。
