The Potential of Digitalization to Promote a Circular Economy in the Water Sector

Abstract

The current amount of data coming from all kinds of devices together with the incessant increase in computing capacity is revolutionizing almost all existing sectors, and the water sector is no exception. The monitoring of urban water cycle infrastructures makes it possible to generate a large amount of data, this information, previously processed, helps to increase the efficiency of the processes carried out in these infrastructures, from catchment to purification and subsequent discharge. This information, in addition to improving internal aspects such as the operation and maintenance of the infrastructures, allows them to be linked to multiple other variables in other sectors, making new technological approaches and more effective management strategies possible. A practical example is wastewater treatment plants. From the perspective of the circular economy, these infrastructures are capable of producing a large amount of resources, which, if properly managed, can reduce the pressure on conventional resources. In this sense, digitization allows the integration of the different market players, thus optimizing the supply and demand of these resources and ultimately advancing the practical application of the circular economy. This paper reviews the potential of digitalization in the urban water sector and proposes numerous practical examples to accelerate the transition towards economic, social, and environmental sustainability.

Digital economy and carbon emission: The coupling effects of the economy in Qinghai region of China

“…The concept of the digital economy has materialized at the intersection of rhetoric and reality, establishing itself as a pivotal model. Recognized as a principal catalyst for economic expansion, it has engendered “far-reaching regional consequences on businesses, employment, and people," inducing transformative economic perturbations [ 55 ]. Particularly in developing nations, the digital economy holds substantial potential for invigorating economic progress, fostering heightened labor and capital productivity, reducing transactional expenses, and facilitating streamlined access to global markets [ 56 ].…”

Bibliometric Analysis of Research Trends in Water Management Aimed at Increasing the Sustainability of the Socio-Economic Development of a Region

“…The possibilities of reducing the water intensity of GRP are most often considered by researchers when substantiating the feasibility of using closed-loop business models to increase the sustainability of regional development [44,45]. To a greater extent, the possibilities of treated wastewater reuse are considered in relation to solving the problems of increasing the sustainability of regional agriculture functioning [46][47][48] and the urban sector [49]. The recommendations contained in scientific articles are aimed at overcoming a significant number of organizational, economic, technical and social barriers that is necessary for the implementation of business models for water reuse.…”

Circular Economy Approaches in the Palm Oil Industry: Enhancing Profitability through Waste Reduction and Product Diversification

“…The model of the circular economy offers a revolutionary framework to directly confront these challenges. By endorsing the reduction, reuse, recycling, and regeneration of resources, the circular economy strives to detach economic growth from the consumption of resources and the deterioration of the environment [6][7][8]. The utilization of this method is not solely a tactical reaction to the ecological predicaments linked with the manufacture of palm oil, but also a chance to bolster economic endurance and societal inclusiveness within the sector [9][10][11].…”
