“…Wastewater is composed of a variety of components as well, including water, organic compounds, inorganic materials, sulfide, heavy metals, and nutrients, such as phosphorous and nitrogen, all of which can be valorized after recovery. The field of wastewater treatment processes applied in practice or under ongoing research and development is vast [26,27]. A review of the methods available to recover and valorize individual wastewater components is not within the scope of this article and is available elsewhere [20,28,29].…”

“…The specific wastewater treatment technologies and their combination need to be carefully evaluated and adapted to the local situation, taking into consideration the economic, geographical, social, and technical parameters [26,27]. A very broad set of wastewater treatment options are found in practice, and a one-size-fits-all solution is not to be expected for the advanced recovery of nutrients from wastewater [26]. High variations in the composition of wastewater streams and case-specific economic viabilities of This example introduces a promising vision for the proposed concept of a multifunctional wastewater management strategy.…”

A wastewater refinery is a multifunctional solution that combines different technologies and processing schemes to recover a spectrum of valuable materials from municipal or industrial wastewater. The concept of wastewater refinery introduces a new perspective on wastewater treatment and management. It aims at making the most of wastewater constituents by co-producing different worthful outputs, such as water, energy, nitrogen, sulfide, and phosphorous. This can turn the treatment of wastewater from a major cost into a source of profit. The wastewater refinery approach is well aligned with the concept of the circular economy. A case study on Qatar’s wastewater revealed the potential recovery of significant quantities of valuable resources embodied in the country’s wastewater. Valorization of organic constituents and the recovery of nitrogen, phosphorus, and sulfide should be given priority. To facilitate the adoption of the wastewater refinery concept, research is required to explore technical and economic bottlenecks.

“…In order to avoid the expensive cost of treating colors, wastewater is frequently discharged directly from textile manufacturers. Globally, it is predictable that 280,000 tons of textile dyes are emitted annually as industrial effluent (Kyzas & Matis, 2020; Yin et al., 2019). Malaysia was the world's 15th largest manufacturer of cotton fibers in 2008, and it was Asia's ninth largest exporter in 2011, with more than RM 10 billion in exports.…”

“…Long‐term exposure to any sort of water pollution is detrimental to human and animal health because it can result in immune suppression and severe poisoning. Furthermore, because it is expensive to treat and prevent contaminations, the negative effects on the environment, notably the imbalance of food webs, would eventually stimulate the economy (Kyzas & Matis, 2020; Zolkefli et al., 2020).…”

As a crucial ingredient for human and animal survival, clean water also contributes significantly to a nation's ever‐expanding economy. However, the availability of clean water has deteriorated as contaminants, such as dyes, have a significant detrimental effect on the pure and clean main waters. Coffee residue with micro‐ and macropores is a potential biosorbent for the removal of synthetic dyes from aqueous solutions. This study aims to determine the efficacy of adsorption of synthetic colors by coffee dregs. Using the Central Composite Design (CCD), the impacts of four adsorption factors (contact time, pH, starting concentration, and adsorbent dosage) were investigated (CCD). For the percent elimination of Remazol brilliant blue R (RBBR) and Remazol brilliant violet 5R, quadratic models were created (RBV‐5R). The ideal adsorption conditions consisted of a pH of 3, a dosage of 5 g of adsorbent, an initial concentration of 10 mg/L, and a contact period of 30 min for RBBR and 60 min for RBV‐5R, resulting in a removal of 49.98% and 93.8%, respectively. The experimental and projected values for RBBR were 96.57% and 95.2% for RBV‐5R, respectively, demonstrating high agreement with minimal errors. The Langmuir isotherm model fit the equilibrium adsorption data of the two selected dyes the best. In addition, the pseudo‐second‐order kinetic model was able to better characterize the experimental data with good respective regression coefficients.
