“…The circular economy concept has found applications in nutrient cycling and inputs in the agri-food industry ( Verger et al, 2018 ; van der Wiel et al, 2020 ; Billen et al, 2019 ). According to Razon (2018) , nitrogen-based fertilizers produced from available atmospheric nitrogen release toxins to the atmosphere during production, but can be prevented through the adoption of new technologies for ammonia production, which successively constitute the major raw material for urea.…”

“…Human waste management currently focuses on nutrient removal rather than on recycling (Coppens et al 2016;Theobald et al 2016;Verger et al 2018). Legislation in Germany obliges WwTP as of 2032 to recover all P and recycle this to agriculture (Heidecke 2018).…”

“…To implement technological measures, a shift in farm practices is required to allow the replacement of inorganic NPK fertilizers (Hanserud et al 2016;Verger et al 2018). However, in the future increasing extraction costs for phosphate rock might give incentives to replace it with bio-based fertilizers (Cordell et al 2009).…”

Regions with intensive agriculture often encounter environmental problems caused by nutrient excess of agro-food-waste systems that have become increasingly linear over previous decades. In this study, nitrogen (N), phosphorus (P), potassium (K) and carbon (C) flows in the whole agro-food-waste system of district Cleves in Germany were quantified simultaneously using substance flow analysis. Moreover, nutrient use inefficiency hotspots were identified to establish options to improve nutrient self-sufficiency as a first step towards nutrient circularity. Data on mass flows and nutrient contents was acquired for the year 2016 from stakeholders, statistical databases, literature and modelling. Organic C was included for flows with potential as organic fertilizer. Results show that animal production drives the nutrient flows in the export-oriented district, with feed import, manure application and losses from housing and manure storage accounting for 40, 45 and 60% of all N, P and K flows, respectively. In particular agriculture is responsible for N losses, with 150 kg N lost ha−1 agricultural land. Crop production surplus and with that soil accumulation of P and K are 515 t and 4100 t respectively. Stoichiometry of N:P:K:C in the different organic materials does not allow direct application and meeting crop requirements without exceeding demand of especially P. Processing of biomass is therefore required. Based on mass, especially manure holds potential for processing into bio-based fertilizers. To improve nutrient cycling and soil C conservation, being an important element for a sustainable agricultural sector, local balances between crop and animal production need to be considered.

“…Biowaste metabolism and nutrient recirculation is a recurring theme in the literature on urban metabolism. It relates to early studies on urban metabolism, the emergence of modern chemistry in the 19th century, as well as concerns about the spoliation of soil fertility led by the missed recirculation in agriculture of human and animal wastes which were in turn polluting the cities (Barles, 2005;Verger et al, 2018;Esculier et al, 2018). Such concerns occupy a prominent role in contemporary debates on sustainability and the circular economy (Cordell, Drangert, White, 2009;Kampelmann, 2016;Lehec, 2018).…”

Given that many voices have argued in favour of combining insights on urban metabolism from different disciplinary angles, there seems to be no lack of general willingness to engage in interdisciplinary research on urban metabolism. Instead, we argue, the central problem lies in the nitty-gritty and mundane practicalities of working across research teams, departments and temporalities. In this paper, we offer a detailed description of an interdisciplinary collaboration that has occurred in practice: a joint effort on the study of potential transition scenarios regarding the metabolism of biowaste in the city-region of Brussels. This interproject collaboration involved four different research teams from three faculties and two universities, each with a specific set of expertise and interests. Biowaste metabolism and nutrient recirculation is a recurring theme in the literature on urban metabolism. It relates to early studies on urban metabolism and concerns about the depletion of soil fertility and different forms of pollution. The paper describes each research project point of departure in order to allow readers with different disciplinary backgrounds to apprehend the distance that separated the projects before they decided to work together on the urban biowaste metabolism. Furthermore, we present moments of convergences that helped to bring these research processes together. Finally, we offer a critical reflection, suggesting both enabling factors and limits of the inter-project collaboration on biowaste metabolism in Brussels. Titre (FR): Conditions et concepts pour la recherche interdisciplinaire sur le métabolisme urbain-le cas d'une collaboration inter-projets sur les biodéchets à Bruxelles Résumé (FR) Étant donné que de nombreuses voix se sont prononcées en faveur de combiner différents angles disciplinaires sur le métabolisme urbain, le problème central de la recherche interdisciplinaire sur le métabolisme urbain n'est pas à trouver dans le manque de volonté des De plus, nous présentons des moments de convergence qui ont permis de rapprocher ces processus de recherche. Enfin, nous proposons une réflexion critique, revenant à la fois sur les facteurs favorables et les limites de la collaboration entre projets sur le métabolisme des biodéchets à Bruxelles.
