Abstract
The business case for circular economy in water management perspective has gain relevance in the recent times. By 2030, it is estimated that 160% of global total available water will be required to satisfy demand of anthropogenic-related activities and increasing waste-related water will be produced. Gaps on the conceptual framing of water reuse within supply chain management are clearly emerging and the demand for decision support systems helping at assessing effective water consumption in industrial setting is pressing. Despite the numerous local initiatives towards wastewater resource usage, barriers remain for its implementation in practice. Through a systematic review of previous studies in this field, the barriers towards the uptake of wastewater use in agriculture were classified according to the PESTEL (political, economic, social, technological, environmental and legal) framework. Alongside political and legal support, it is identified that for an economically and environmentally sustainable scheme for incentivising the deployment of feasible technologies, there is also a need to gain acceptance for wastewater usage in society in order to enhance the deployment of existing technological solutions. Addressing these factors in tandem can aid the development towards a circular economy for wastewater.
Highlights
Circular economy is one of the most important paradigms emerging in the research of industrial activity, focusing on a system for industrial and commercial activity which is Circular Economy and Sustainability (2021) 1:413–433 regenerative and restorative at the same time [1]
To shed light on the potential path for water reuse implementation under circular economy understandings, the analysis presented in this paper addresses the research questions:
A circular economy approach to water reuse be positioned as a concept to help solve the water resource crisis by linking circular economy as a political aim with one which can be delivered through action [3, 5, 6]
Summary
Circular economy is one of the most important paradigms emerging in the research of industrial activity, focusing on a system for industrial and commercial activity which is Circular Economy and Sustainability (2021) 1:413–433 regenerative and restorative at the same time [1]. The European Commission drafted the ‘A Resource Efficient Europe’ action plan referred towards the integration of water resources to be included into measurements of resource efficiency and called for a step towards the collection of statistics that record the efficient use of abstracted water [4, 8, 9]. This is in response to projections of increased water stress and shortage, and it is estimated that by the year 2030, more than 160% of the total available water volume in the world will be required to satisfy global water requirements [10]. This calls for more inventive and currently unconventional methods for utilising water more effectively
