“…To increase the collection of waste and perform anaerobic digestion, collaboration with green space service companies may be also necessary. The collection is highly dependent on the season, and supply is assumed to be available around 180 days per year [49]. Moreover, a good differentiation between lawn cutting and pruning scraps is needed to avoid a high lignin concentration.…”

Background: The anaerobic digestion process is well studied and developed since the last 50 years, notably for farming implementation. Furthermore, the international energy agenda has shifted in favor of renewable resources. In this context, anaerobic digestion has been highlighted as a valuable source of green energy. At urban scale, since the 2000s, some eco-friendly districts and cities tried to integrate this process as valorization treatment, with different approaches and results. The objective of this study is to provide a feedback from these anaerobic digestion projects at urban scale. Methods: To construct this paper, 15 international projects of urban waste valorization were selected and studied. Three of these projects are developed to describe the different elements and processes implied in these valorization systems. Thus, in situ and ex situ anaerobic digestions are described with functional implementation and units in development or abandoned. Once the leading steps and main parameters on waste management system identified, the discussion is performed to compare the operational systems implemented in the 15 cases studies. The analysis takes processes and biological parameters into account in addition to social, financial, and ecological elements available. The achievements and limits of case studied linked to their context, bringing advice and recommendations. Results: From these real cases and projects, we highlighted relevant information for further urban waste valorization system. Among others, the most frequent organic deposits produced at urban scale are identified, as well as the typical quantities generated. Collection, storage, and pretreatment processes were investigated to provide information about how they are conducted in situ and ex situ. Concerning some technical points, CSTR and UASB configurations are also identified as predominant reactors used to lead wet AD process at urban scale, due to practical aspects and characteristics of feedstock. Concerning the digestate, nutrients contents make it an interesting fertilizer for agricultural valorization. To its stabilization, the composting process is mainly deployed after anaerobic digestion of urban waste. The valorization of biogas produced with in situ urban AD is generally performed with CHP unit, due to the small quantity of methane. When the valorization is operated ex situ, processes are in link with local users' needs and energy transition policy.

“…Moreover, broader public support may be built when multiple stakeholders related to particular functions share support for a MLU development [48,54]. Finally, CUM and MLU are seen as ways to reconnect communities with their surrounding environment [6,54,55], e.g., reconnecting food production and consumption with restaurants using products from their own rooftop farm [45].…”

Cities pose environmental challenges but also offer possibilities to close material and energy loops and connect multiple societal and ecologic services. This article reviews and brings together the literature on two important new research directions that address urban sustainability by integrating functions or material flows: Circular Urban Metabolism (CUM) and Multifunctional Land Use (MLU). We focus on challenges to MLU and CUM and strategies to facilitate their realization. The review shows that although MLU and CUM differ in what they integrate, they face partly similar integration challenges. In both fields, the collaboration between actors related to particular functions (water safety, recreation), high investment costs and uncertainties about costs and benefits, and legislation that hampers integration are identified as challenges. In both fields, strategies are proposed to facilitate the collaboration between actors. However, other challenges and strategies are specific. Whilst MLU scholars mostly highlight socioeconomic aspects of realizing integration, CUM scholars focus more on technical aspects. We find limited cross-fertilization between both fields so far. To stimulate discussion and knowledge exchange, we introduce 'integration of urban functions' as a shared idea for a sustainable urban system. To find further solutions for integration challenges, we propose conceptualizing MLU or CUM initiatives as processes of change, which requires connecting across previously separate 'worlds' and changing previously established monofunctional ways of working.

“…Subsurface qualities were exploited. The urban design of Lanxmeer is based on the concept of permaculture, this concept is also used to derive the application of the technical systems (van Timmeren, Sidler, and Kaptein 2007). The project is illustrative of the Reversed Engineering with Nature concept; trade-offs and synergies are found between the categories of civil constructions, water, energy and soil and implemented as a continuous system that runs through the surface and subsurface.…”

“…An example of urban development allowed in an area set aside for water extraction is Lanxmeer (Culemborg, the Netherlands) where strict measures for the spatial layout and public space design, together with regulations governing water use and discharge are intended to safeguard water quality ( Figure 6). Permaculture concepts underlie Lanxmeer's design for adopting natural processes as a core strategic element within the planning process (van Timmeren, Sidler, and Kaptein 2007).…”

The subsurface is a technical space, the "engine room of the city, " that incorporates the vital functions of water and energy supply, communication systems, sewers and drainage. Natural systems too -crucial for stable, dry, cool and nature inclusive cities -are also largely dependent on the quality of the subsoil. The subsurface is critical in an era of climate and demographic changes, the energy transition and economic uncertainty and constraints. However, due to the domain's current segregation and a weak urban design and planning connection, crucial design potential, benefits and innovations, remain unexploited. This paper first introduces an innovative systems approach, the System Exploration Environment and Subsurface (SEES), to recognise the subsurface as an "underarching" domain for urban planning and design. The physical impact of the subsurface on the surface quality is described for the categories: civil constructions, water, energy and soil/ecology. After setting understanding of the surface and subsurface as one united space, the paper will go into using the SEES as knowledge brokerage tool, integrating the subsurface artefacts into the design process and how the concept of Reversed Engineering with Nature is useful to uncover synergies between subsurface technologies, new urban maintenance regimes and scripts for design.
