Increases in population and per capita consumption of energy and animal products will exacerbate nutrient losses and resource depletion, pollution levels and land degradation, further threatening the quality of our water, air and soils, affecting climate and biodiversity. A new strategic research effort is needed to reduce nutrient losses and improve nutrient use efficiency across all sectors, thereby creating the foundation for a green and circular economy that produces more food and energy while reducing environmental pollution. This project aims to provide sustainable strategies for nutrient and energy recovery from bio-waste with economic valorization of the recovered nutrient products as green substitutes for chemical fossil-based fertilizers in food production. To this end, three complementary research work packages (WP) will be executed, thereby covering holistic nutrient valorization chains: 1) Bio-based fertilizer production, 2) Process modelling for optimization, and 3) End-product formulation and evaluation. In WP1, pilot units and treatment trains of the most established nutrient recovery technologies will be implemented in order to produce raw fertilizer products from (digested) bio-waste. In WP2, new process models will be developed for nutrient recovery systems, in particular for membrane filtration. In view of optimization, predictive models will be developed for product quality characteristics as purity, particle size, fertilizer release rates. Adapted model calibration and validation methods will be devised and tested. Finally, in WP3, the quality of the produced fertilizers will be evaluated and upgraded to compositions acceptable for agricultural use according to current regulation. Nutrient use efficiencies and environmental impact of the formulated end-products will be assessed in agricultural field trials. As such, the proposed project further develops the concepts of maximally closing nutrient cycles (= waste to feed). This will open up new opportunities for sustainable and more bio-based economic growth and thus create a win-win-win situation for the environment, the society and the economy in Canada, and beyond.

能源和动物产品的人口和人均消耗的增加将加剧营养损失和资源枯竭，污染水平和土地退化，进一步威胁到我们的水，空气和土壤的质量，从而影响气候和生物多样性。需要一项新的战略研究工作，以减少营养损失并提高所有领域的养分利用效率，从而为绿色和循环经济创造基础，从而产生更多的粮食和能源，同时减少环境污染。该项目旨在提供可持续的策略，从而提供从生物废物中的营养和能源回收，并以经济价值将回收的营养产品作为绿色替代品作为粮食生产中化学化石肥料的绿色替代品。为此，将执行三个互补的研究工作包（WP），从而涵盖整体营养价值链：1）基于生物的肥料生产，2）用于优化的过程建模，3）最终产品配方和评估。在WP1中，将实施最成熟的营养恢复技术的试点单位和治疗列车，以从（消化）生物废物中生产原始的肥料产品。在WP2中，将为营养恢复系统开发新的过程模型，特别是针对膜 过滤。鉴于优化，将针对产品质量特性开发预测模型，因为纯度，粒度，肥料释放速率。将设计和测试改编的模型校准和验证方法。最后，在WP3中，根据目前的调节，将评估和升级生产的肥料的质量，并升级为可接受的农业用途。在农业现场试验中，将评估养分的效率和面积最终产品的环境影响。因此，拟议的项目进一步发展了最大闭合营养周期的概念（=饲料废物）。这将为可持续和基于生物的经济增长提供新的机会，从而为加拿大及其他地区的环境，社会和经济创造双赢的局面。
