The report covers many areas of water reuse, from basic principles to application and case studies. The authors declare no conflict of interest. From those contributing to the OECD Survey, four cities including Amsterdam, Rotterdam, Barcelona Metropolitan Area and Paris and Flanders as a region have incorporated water and sanitation into their circular economy initiatives. This study has reviewed (a) projects conducted in the context of the collective research programme Water in the Circular Economy (WiCE), an initiative of the Dutch and Flemish drinking water utilities and KWR Water Research Institute, and (b) case studies conducted in the context of NextGen, a research project funded by the European Unions Horizon 2020 Research and Innovation Programme under grant agreement No. In. /TrimBox [ 0.0 0.0 612.0 792.0 ] [23,24,25,26,27]). These articles were complemented with circular water solutions taken from 22 cases, 10 from Nextgen, a European-funded research project, and 11 from Water in the Circular Economy (WiCE), a research programme of the Dutch and Flemish water utilities and KWR, with partners from the water authorities, regional and local governments, industry and academia. Explorethe technical reports and other background materialthat inform the main report. xYUH&% The normative, governance and implementation challenges should be urgently considered by policymakers and decision-makers at large. As such, a key challenge in todays world is to ensure enough water for use across all sectors, while respecting environmental flows, and doing so sustainably [6,7,8]. KEY POLICY MESSAGES This policy brief captures the key messages from: UNESCO and UNESCO i-WSSM. Wastewater is and should be considered a valuable resource from which energy and nutrients can be extracted, as well as an additional source of water. Given that we restricted our search to Scopus and Google Scholar, using other databases could have altered the current result. UNESCO said the Flanders region had created different spaces for stakeholder collaboration with a "strong technical innovation approach". In this paper, we will adopt the term circular economy of water (CEW). >> Finally, water has several natural entry points (including rivers and aquifers), and it follows numerous streams in human and natural systems [1, 19, 20]. xref However, it cannot be a strategy because it exceeds the defined boundaries of the CE system. 0000568295 00000 n We found that many authors in their writings do not differentiate between the terms recycled, reclaimed, and reused. Despite the growing interest in the CEW, broader research efforts remain sparse.

Companies are being supported, as part of a 2017 "Circular Flanders" programme to close water loops and demonstrate projects that could be scaled-up to benefit the local communities. Moreover, new legislation should encompass international agreements to allow the promotion and development of transboundary CE strategies and solutions. 0000465997 00000 n 0000565787 00000 n McGraw-Hill, 1561 1567 (pp 13541383 of the PDF electronic version). 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.

Water reuse from a circular economy perspective and potential risks 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. The report highlights the findings and conclusions from technical background reports, from in-depth analysis of several case studies, and from the feedback received during workshops and seminars with main stakeholders. Read the full reportto find out more about the four key actions. To move toward the ideal utility of the future, facilities must be designed, planned, managed, and operated effectively and efficiently. Wastewater can boost crop yields without harm if pathogens, salts, and other pollutants are removed. Restore is a CE principle and an important action for the functioning of natural systems [37]. Ferronato, N.; Torretta, V. Waste Mismanagement in Developing Countries: A Review of Global Issues. In addition, we must highlight the fact that the wastewater was discussed as a whole, when it is known that there are several types of wastewaters and that the level of treatment differs from one type to another. 0000460846 00000 n Normative aspects should consider enabling mechanisms such as a system of incentives and benefits for implementing CEW initiatives such as nutrient Recover or the use of disincentives like taxation to discourage wasteful linear processes.

For The purpose of the report is to share the knowledge created and the conclusions from the initiative with stakeholders and practitioners involved in wastewater planning, financing, and management (including water utilities, policy makers, basin organizations, and ministries of planning and finance) to encourage a paradigm shift in which the value proposition of wastewater in a circular economy is recognized. Rgener, F. (2021). Its equipment uses captured CO2 to dye textiles in a process which uses no water. If you continue to navigate this website beyond this page, cookies will be placed on your browser. When reused, water can have the same quality/value as in previous uses or and this is more frequently the case the quality may not be as high (this is therefore a case of the downcycling of water). 0000411843 00000 n Sridhar, R.; Sachithanandam, V.; Mageswaran, R.

Hughes, S. Authority Structures and Service Reform in Multilevel Urban Governance: The Case of Wastewater Recycling in California and Australia. [27]), treatment is what differentiates Recycle from Reuse. In recent years, some industries such as the paper industry and dyeing industries have progressively adopted recycling solutions in response to water pricing and environmental regulation [64]. Woodhead Publishing, pp 117142, Chapter These solutions have been applied in several contexts, such as space stations, brewery facilities or wastewater recycling from showers, washing machines and dishwashers. Given the level of heterogeneity of research in this sector, it will be useful to bring the studies together to better understand when, what, and where articles have been published, and which results are most relevant for decision-making. Kunz, N.C.; Fischer, M.; Ingold, K.; Hering, J.G. Share your water technology stories with us Provided by the Springer Nature SharedIt content-sharing initiative, Over 10 million scientific documents at your fingertips, Not logged in 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. The purpose of this study was to carry out a systematic review of the CE in the water and wastewater sector. CAS In. All articles published by MDPI are made immediately available worldwide under an open access license. Rationalising water use (e.g. ( x m p . 0000419411 00000 n The Circular Water Economy | SpringerLink Future urban development requires approaches that minimize resource consumption and focus on resource recovery, following principles of the circular economy. Two hospitals in the city, including the Franciscus Gasthuis general hospital and the Erasmus University Medical Center are already actively engaged in this process. A great deal ofapplied research has been published, but the theoretical understanding of the CEW is still developing, and the terminology is employed ambiguously. Cascading combines multiple CE strategies (such as Recycle, Reuse and Recover) even in the water sector (see, e.g. Towards circular economy - a wastewater treatment perspective, the ; Clarke, M.; Devereaux, P.J. This ranges from using alternative resources such as rainwater and groundwater, right through to promoting a water saving culture, from cisterns to wells and irrigation channels. In practice, Avoid is rarely applicable because it is usually difficult to stop using water. For example, Repair, Refurbish and Remanufacture are strategies for manufactured products, while Repurpose refers to the use of discarded products to make new ones. 512 0 obj organic matters, chemical elements, biochemical compounds) and the retention or generation of energy. Water is a focus for UNESCO as one of the Sustainable Development Goals, as Goal 6 is Ensure access to water and sanitation for all. The initiative included multiple consultations and workshops with stakeholders working on wastewater management projects in the LAC region.
