“…These researchers also proclaim that organizations should work towards creating a more sustainable supply chain. Saad et al [155] state that strategic relationship management is the maintenance and development of engagement that is sustainable and continual by an organization with its customers and suppliers. Accordingly, the current inquiry makes an original contribution since it proved a significant relationship between environmental sustainability and personal relationships and gifts, which assists in narrowing the knowledge gap of inquiries that mandated further investigation on sustainable environmental procurement practices and decision-making [17][18][19][20][21][22][23][24][25][26][27].…”

“…Environmental sustainability is of mutual benefit to all stakeholders, which can be facilitated by closer relationships and small gifts. There is a dearth of inquiry that examines parallel sustainability and risk management issues [103], so this result added to the TBL framework and limited sustainable B2B procurement discourse in this regard [155][156][157][158][159][160].…”

The recent COVID-19 pandemic, and subsequent invasion of Ukraine by Russia, has demonstrated to the world the volatile and fragile nature of global supply chains. Hence, this study is based on research gaps that propose new sustainable business-to-business (B2B) procurement/supplier models that consider different factors across industries and uses the triple bottom line (TBL) framework as the theoretical underpinning. The study used a quantitative methodological approach and convenience sampling to survey 445 organizations in a B2B procurement context in South Africa. The data were analyzed via structural equation modeling. The inquiry revealed that service quality was important to determine access to personnel and environmental sustainability, which had a favorable influence on personal relationships and gifts and, in turn, positively influenced relationships with salespeople and management. Culture, employment equity, and affirmative action positively affected Black Economic Empowerment status which had a favorable influence on the preference of suppliers’ salespeople. Several other positive associations were revealed, which resulted in a unique theoretical supplier preference contribution to the TBL framework. The study also provides organizations with a number of practical benefits stemming from the associations between the new sustainable B2B procurement/supplier constructs that are important as value-added business activities in an African developing economic context.

“…Recently, Saad et al [133] reported the technoeconomic analysis and process modeling of the electrocoagulation and the electrocoagulation-membrane (ECM) system for the removal of the dyes. The techno-economic feasibility of the newly developed ECM system and EC alone was studied using John's Macintosh Project (JMP) software.…”

“…The ECM system was 40 % cheaper in comparison to the EC at 1 V voltage and 1 g of NaCl electrolyte with 1.079 million MYR total cost. However, the EC standalone process is 82.07 % cheaper than the photocatalytic process, with a total cost of 0.325 million MYR [133].…”

The textile industry utilizes numerous chemicals ranging from solvents to resins and caustic soda to bleach, having a harsh environmental impact. A large amount of colored dye in wastewater is released. Non-biodegradable heavy metals and chlorine accumulate in organs of marine and terrestrial life, leading to various diseases. So, there is an urgent need to treat textile wastewater. Up to date, techno-economic analyses of all electrochemical processes have not been reviewed for textile wastewater treatment. In this review, the focus is on the tertiary treatment methods, mainly on electrochemical treatments, i.e., electrocoagulation, electro-Fenton, electrooxidation, photoelectrochemical (PEC) process, and solar electrophoto-Fenton process (SPEF) with their mechanisms and techno-economic analyses. SPEF treatment was found to be advantageous in terms of efficiency and economic perspective as it utilizes solar energy instead of electrical energy and the cost of the PEC process can also be recovered by the generation of hydrogen.

“…Different industries such as leather, pharmaceutical, paper, etc. use large amount of water and produce wastewater containing many organic and inorganic pollutants (Chen et al , 2022; Mahmoodi 2013a, 2013b; Njuguna and Schönherr, 2022; Saad et al , 2022; Xu et al , 2022). For that reason, a variety of physical, biological and chemical processes are implemented for removing dye from wastewater (Kadirvelu and Fathima, 2022; Kalidason and Kuroiwa, 2022; Mahmoodi and Mokhtari-Shourijeh, 2008, Mahmoodi and Arami, 2009; Oke and Mohan, 2022).…”

Purpose Environmental issues and lack of drinking water have forced researchers to find some alternatives to wastewater treatment. Because dyes are used in a variety of industrial applications such as textile and pharmaceutical, wastewater of these factories leads to several environmental problems. Using catalysis under ultraviolet-irradiation (photocatalysis) is one of the cases that is used in wastewater treatment. The purpose of this work is the photocatalytic degradation of dye (Reactive Red 198) and pharmaceutical (tetracycline) using MIL-53(Fe) and MIL-100(Fe). Design/methodology/approach In this work, Reactive Red 198 (RR198), an anionic dye and tetracycline as a pharmaceutical are tested with two catalysts, MIL-53(Fe) and MIL-100(Fe). Catalyst synthesis method and characterization were discussed by X-ray diffraction, scanning electron microscopy and Fourier Transform Infrared analyses, and their results are described in detail. Findings Dye concentration varies among 15, 20, 30 and 40 mg/L for MIL-100(Fe) for which the removal percent is 97%, 94%, 89% and 58% and for MIL-53(Fe), dye concentration increases from 20 to 40, 60 and 80 mg/L, the removal percent of which is 98%, 88%, 75% and 50%. Pharmaceutical degradation by MIL-53(Fe) and MIL-100(Fe) was 75% and 80%, respectively. Originality/value Photocatalytic degradation of RR198 and tetracycline using MIL-53(Fe) and MIL-100(Fe) was not studied in detail.
