“…Modern cities have mainly followed centralized approaches to organize waste management, as well as other resource management systems such as for energy and water [37]. Drivers of centralized approaches include economies of scale and transport costs [38].…”

“…It has been suggested that partial decentralization of biowaste management can better support the transition from linear to circular systems, and shift perspective from 'waste' management to a wider resource management approach [45]. Nevertheless, the authors of [37] characterized the current scientific literature on technologies for decentralized biowaste treatment 'fragmented and incomplete'. To begin filling this gap, they classified and compared decentralized options for urban biowaste treatment (including AD) through extended material flow analysis (EMFA).…”

“…For example, according to [54], decentralized systems consist of small-scale AD plants that are approximately '75 m 2 (15 m × 5 m) to accommodate all the equipment and the required space around'. In contrast, the authors of [37] describe decentralized treatment systems as: 'A class of treatments that encompasses relatively small facilities capable to metabolize less than approx. 10 tonnes biowaste/year'.…”

The potential contribution of decentralized approaches in implementing biowaste recovery systems has attracted interest in urban policy making and scientific research. Although the scientific literature on the topic is rapidly increasing, it is still limited and scattered. A comprehensive overview of current scientific knowledge is thus needed to support future research on decentralized options for biowaste recovery systems. Anaerobic digestion (AD) is a mature biowaste treatment technology that recovers energy and nutrients, and can close urban resource loops. Through a scoping literature review, this paper investigated decentralized AD and its potential contribution in implementing urban biowaste recovery systems. We identified opportunities and challenges for planning of decentralized AD, and concluded that these mainly concern: (a) digestate management; (b) the potential for local circularity with product valorization in outlets such as urban agriculture; and (c) the development and application of decision support tools. The findings highlighted the need to enhance scientific evidence on the impact of decentralized AD in different urban contexts. Results from published studies were highly context-specific, making it difficult to draw general conclusions. This study can support the transition to integrated planning of AD and wider urban biowaste recovery systems. Such planning must include a comprehensive analysis of configuration approaches.

“…Since 2016, the LOUISE_ECO team has developed spatial analysis and scenarios' construction in three studies commissioned by the Brussels Environment agency on the questions related to biowaste management. These studies have respectively focussed on the scope of decentralised biowaste treatment (Bortolotti, Kampelmann, De Muynck, 2018); the estimation of potential biowaste production and collection in the Brussels region (Bortolotti et al, 2018a); and the feasibility of building and operating an industrial biowaste treatment plant within the regional administrative borders (Bortolotti et al, 2018b).…”

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.

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.
