“…Adsorption by natural adsorbents is an efficient and cost-effective method to recover N and P from wastewaters. Adsorbed nutrients, then, can be desorbed to be used as fertilisers [41]. Alternatively, nutrient enriched adsorbents can be applied to the soil as amendments to improve soil fertility [42].…”

The wastewater sector paradigm is shifting from wastewater treatment to resource recovery. In addition, concerns regarding sustainability during the operation have increased. In this sense, there is a need to break barriers (i.e., social, economic, technological, legal, etc.) for moving forward towards water resource recovery facilities and demonstration case studies can be very effective and insightful. This paper presents a new water resource recovery case study which is part of the Horizon 2020 EU Project “Achieving wider uptake of water-smart solutions—Wider Uptake”. The final aim is to demonstrate the importance of a resource recovery system based on the circular economy concept. The recovery facilities at Palermo University (Italy) are first presented. Afterwards, the resource recovery pilot plants are described. Preliminary results have underlined the great potential of the wastewater treatment plant in terms of resources recovery and the central role of the University in fostering the transition towards circular economy. The fermentation batch test highlighted a volatile fatty acids (VFAs) accumulation suitable for polyhydroxyalkanoates (PHAs) production. The results of static adsorption and desorption tests showed that the highest amount of adsorbed NH4+ was recorded for untreated and HCl-Na treated clinoptilolite.

“…It has a lower percentage of solids than primary sludge, with a typical value of 1% (99% humidity). Typically, SS treatment in the sludge streamline of a WWTP pursues volume reduction via thickening and dewatering, as well as a biological stabilization via digestion In the scientific literature, there are many studies that describe the current technologies applied to efficiently recover nutrients from different residual flows, including wastewater [15][16][17], human urine [18][19][20], industrial effluents [21,22], and SS [1,[23][24][25][26]. Notwithstanding the great number of existing studies on the topic of nutrient recovery, only a few are available on nutrient recovery from ADS.…”

The world is currently witnessing a rapid increase in sewage sludge (SS) production, due to the increased demand for wastewater treatment. Therefore, SS management is crucial for the economic and environmental sustainability of wastewater treatment plants. The recovery of nutrients from SS has been identified as a fundamental step to enable the transition from a linear to a circular economy, turning SS into an economic and sustainable source of materials. SS is often treated via anaerobic digestion, to pursue energy recovery via biogas generation. Anaerobically digested sewage sludge (ADS) is a valuable source of organic matter and nutrients, and significant advances have been made in recent years in methods and technologies for nutrient recovery from ADS. The purpose of this study is to provide a comprehensive overview, describing the advantages and drawbacks of the available and emerging technologies for recovery of nitrogen (N), phosphorus (P), and potassium (K) from ADS. This work critically reviews the established and novel technologies, which are classified by their ability to recover a specific nutrient (ammonia stripping) or to allow the simultaneous recovery of multiple elements (struvite precipitation, ion exchange, membrane technologies, and thermal treatments). This study compares the described technologies in terms of nutrient recovery efficiency, capital, and operational costs, as well as their feasibility for full-scale application, revealing the current state of the art and future perspectives on this topic.

“…The lack of this resource in the planet led to the development of biological and chemical processes to recover nutrients from wastewater and sludge [ 62 , 63 ]. In the review of Saliu and Oladoja [ 64 ], the authors stated the possibility of nutrient recovery from different kinds of nutrient-rich wastewater including that from agricultural practices and from industrial and municipal facilities. Additionally, the reviewed literature confirmed the viability of the recovered nutrients for reuse as fertilizer in agricultural practices, as their fertilizing effect is comparable with or is even better than commercial fertilizers.…”

Over the last few years, wastewater treatment plants (WWTPs) have been rebranded as water resource recovery facilities (WRRFs), which recognize the resource recovery potential that exists in wastewater streams. WRRFs contribute to a circular economy by not only producing clean water but by recovering valuable resources such as nutrients, energy, and other bio-based materials. To this aim, huge efforts in technological progress have been made to valorize sewage and sewage sludge, transforming them into valuable resources. This review summarizes some of the widely used and effective strategies applied at pilot- and full-scale settings in order to valorize the wastewater treatment process. An overview of the different technologies applied in the water and sludge line is presented, covering a broad range of resources, i.e., water, biomass, energy, nutrients, volatile fatty acids (VFA), polyhydroxyalkanoates (PHA), and exopolymeric substances (EPS). Moreover, guidelines and regulations around the world related to water reuse and resource valorization are reviewed.
