water reuse within a circular economy context
Cascading works best under proximity, in other words when consecutive uses are located close to one another and with technologies working in synergy [71]. Dzidic, P.; Green, M. Outdoing the Joneses: Understanding community acceptance of an alternative water supply scheme and sustainable urban design. So Paolo, Brazil: Water Scarcity and Water Reuse Seminar, November 2018. Especially in low- and middle-income countries, rapid urbanization has created various water-related challenges, including degraded water quality and inadequate water supply and sanitation infrastructure, particularly in expanding peri-urban and informal settlements. Only about 60 percent of LACs population is connected to a sewerage system, and only about 3040 percent of the regions wastewater that is collected is treated. 5 city-wide circular water strategies flagged by UNESCO 10.1016/s0015-1882(18)30329-x . xYUH&% A session on circular economy approaches was convened on Wednesday August 28th. 0000460994 00000 n [12]); it is mainly used to refer to either eliminating inefficient uses or reducing water use. In. Overall, Rethink can be considered an overarching strategy that gives shape and content to all CEW strategies while creating synergistic links between them [35, 36]. Water and circular economy: a white paper. The circular . Share your water technology stories with us A taxonomy of circular economy indicators. In this study, the system boundaries are those delimited by any natural or artificial system in which water is managed for economic purposes because the CE is an economic model.

In any sector, the CEW offers novel opportunities for innovation, governance, business models and water management together with new views on engineering and technological solutions (e.g. 0000462023 00000 n This interpretation fits in with the meaning of Reuse for products in common CE practices where, for example, the same object (such as a rental tool) is reused by different people. By developing consistent terminology and a clear focus on strategies relating to the CEW, this study aims to integrate past and future studies and facilitate the transition towards sustainable water management. 0000459490 00000 n While the benefits are largely recognised and are fundament to help achieve a Circular Economy, it remains mostly unexploited with the uptake continuing to remain low. Wastewater treatment frees scarce freshwater resources for other uses or preservation. The opinions expressed in this publication are those of the authors only. In the few cases, Avoid is mentioned (e.g. Watari, T.; McLellan, B.; Giurco, D.; Dominish, E.; Tezuka, T.

Sustainability Science, pp 117, Kakwani NS, Kalbar PP (2020) Review of circular economy in urban water sector: challenges and opportunities in India. Like Avoid, Replace is not an easy strategy to implement because water is a relatively cheap resource with unique physicochemical and biochemical properties.

Water Reuse within a Circular Economy Context (Series II). Research 293: Water Reuse in the Context of the Circular Economy - EPA This process starts with the water itself (which can be used for agriculture, industry, and even human consumption), followed by nutrients (nitrogen and phosphorus) and energy generation. The CEW does also embrace traditional, socially innovative and nature-based solutions [29,30,31,32] as long as those solutions close loops, use water efficiently, prevent waste or maintain water quality for long periods. Available online: Marsh McLennan. Bellver-Domingo, A.; Hernndez-Sancho, F. Circular economy and payment for ecosystem services: A framework proposal based on water reuse. The possibility of adding additional CE strategies was considered based on the verification of case studies and discussions with several experts and practitioners in the sector. At both sessions, findings of the initiative were presented and feedback from participants provided. Design/methodology/approach By nature, water has multiple purposes, and it can always be repurposed (e.g. In: Wilhite D, Pulwarty RS (eds) Drought and water crises: integrating science, management, and policy. The initiative included multiple consultations and workshops with stakeholders working on wastewater management projects in the LAC region. Circ Econ Sustain 1(3):9951018, Article Except for Rethink, which is considered a stand-alone and overarching strategy, the strategies have been allocated to three categories: decreasing, optimising and retaining. 0000406443 00000 n Google Scholar, Van Hullebusch ED, Bani A, Carvalho M, Cetecioglu Z, De Gusseme B, Di Lonardo S, Zeeman G (2021) Nature-based units as building blocks for resource recovery systems in cities. endobj mud and proteins) [78,79,80]. Water and the Circular Economy. This approach included specific material flows: water, food, phosphate, waste, electricity and heating. For the paradigm shift to happen, incentives are needed to encourage sustainable wastewater investments that consider reuse and resource recovery and promote circular economy principles. It also requires the development of approaches in which the water output from a process can constitute an input for another process in an environmentally sustainable, socially and economically viable manner. We opt for the term Avoid because it evokes the ideas of renouncing and preventing water use at the same time. Two sessions on wastewaterPublic Private Partnerships in Wastewater and Business Models to Foster Wastewater Reuse and Resource Recovery in Wastewater Treatment Plantswere co-convened with CAF, to facilitate discussions with governments and the private sector on the challenges and opportunities associated with promoting wastewater reuse and recovery. Its equipment uses captured CO2 to dye textiles in a process which uses no water. exhaust hot water in steelmaking). xref Replace is similar to Avoid because both imply renouncing water.

Living organisms, wastewater treatment and industrial processes need minimum amounts of water to function. Circular Economy of Water: Definition, Strategies and Challenges - Springer This aspect is facilitated by the fact that water is in flux and is required in most if not all human activity. As such, this study identifies three main challenges normative, governance and implementation that require further research and attention of policy makers to facilitate the transition to a full CEW. /StructParents 0 Del Borghi, A.; Moreschi, L.; Gallo, M.

Furthermore, population growth, economic development and changing consumption patterns have dramatically increased water demand, resulting in mounting tensions over water supply [3,4,5]. 0000538984 00000 n For 2023 RAI Amsterdam.

The Flemish vision follows the line established by the EU Circular Package and the new Circular Economy Action Plan that aims at emphasising the reuse of water and the contribution of the bio-economy to a circular economy. 0000417153 00000 n Furthermore, water is easily available due to a large network of infrastructures that have been built and maintained over a long time. /MediaBox [ 0.0 0.0 612.0 792.0 ] /MarkInfo << /Marked true >> Water itself can be recovered during Recover processes. It is clear that even though there are countries with wide experience in the area of CE in the water and wastewater sector, its implementation is insipient, and there is a lack of understanding concerning the need to work on consensual indicators to facilitate its application in a more comprehensive way. One of the key advantages of adopting circular economy principles in the processing of wastewater is that resource recovery and reuse can transform sanitation from a costly service to one that is self-sustaining and adds value to the economy. We provide a wide array of financial products and technical assistance, and we help countries share and apply innovative knowledge and solutions to the challenges they face. Nevertheless, there are several examples of water-free solutions such as water-free toilets based on vacuum flush, vacuum pumps in industry, dry wash sprays or atmospheric-plasma technologies for clothing [40,41,42,43].

It is being pursued with greater policy focus, in Europe and elsewhere, including for water. 0000464989 00000 n Furthermore, it also encouraged local plans to disconnect the rainwater collection and install green roofs in new construction. Accordingly, we provide the definition of the CEW as an economic framework for reducing, preserving and optimising the use of water through waste avoidance, efficient utilisation and quality retention while ensuring environmental protection and conservation.
