Recognition of human excreta as a resource, rather than as waste, has led to the emergence of a range of new and innovative nutrient recovery solutions. Nevertheless, the management of human excreta remains largely rooted in current sanitation and wastewater management approaches, which often makes nutrient recovery an add-on to existing infrastructures. In this paper, we argue that framing human excreta management as a resource recovery challenge within waste management obscures important trade-offs. We explore the factors that would be brought to the fore by reframing human excreta management as part of food and farming systems. We find that such a reframing would accentuate (at least) six aspects of critical importance that are currently largely overlooked. Recognizing that the proposed framing may also have its limitations, we argue that it has the potential to better guide human excreta management towards long-term global food, soil, and nutrient security while reducing the risk of compromising other priorities related to human and environmental health.

人们认识到人类排泄物是一种资源，而不是废物，导致出现了一系列新的创新性养分回收解决方案。尽管如此，人类排泄物的管理仍主要植根于当前的卫生和废水管理方法，这通常使营养物回收成为现有基础设施的附加。在本文中，我们认为将人类排泄物管理框架化为废物管理中的资源回收挑战掩盖了重要的权衡。我们探索通过将人类排泄物管理重新定义为粮食和农业系统的一部分而引起关注的因素。我们发现，这样的重新设计将（至少）强调当前被严重忽视的六个至关重要的方面。认识到提议的框架也可能有其局限性，
