“…In the specific context of membrane technology, most of the analyses have been focused on the usage phase, analysing the implementation of the membranes in applications such as desalination or wastewater treatment [155][156][157][158][159], whereas, a lower number of studies have been devoted to the analysis of the EoL membrane management stage. However, the directive 2008/98/EC on waste already included the life cycle perspective and the Life Cycle Thinking considerations within the principle of extended responsibility of waste management from the side of manufacturers [11].…”

It is estimated that Reverse Osmosis (RO) desalination will produce, by 2025, more than 2,000,000 end-of-life membranes annually worldwide. This review examines the implementation of circular economy principles in RO technology through a comprehensive analysis of the RO membrane life cycle (manufacturing, usage, and end-of-life management). Future RO design should incorporate a biobased composition (biopolymers, recycled materials, and green solvents), improve the durability of the membranes (fouling and chlorine resistance), and facilitate the recyclability of the modules. Moreover, proper membrane maintenance at the usage phase, attained through the implementation of feed pre-treatment, early fouling detection, and membrane cleaning methods can help extend the service time of RO elements. Currently, end-of-life membranes are dumped in landfills, which is contrary to the waste hierarchy. This review analyses up to now developed alternative valorisation routes of end-of-life RO membranes, including reuse, direct and indirect recycling, and energy recovery, placing a special focus on emerging indirect recycling strategies. Lastly, Life Cycle Assessment is presented as a holistic methodology to evaluate the environmental and economic burdens of membrane recycling strategies. According to the European Commission’s objectives set through the Green Deal, future perspectives indicate that end-of-life membrane valorisation strategies will keep gaining increasing interest in the upcoming years.

“…Eco-architecture involves a wide range of aspects, is the intersection of multiple disciplines and types of work and is a comprehensive systematic project that requires the attention and participation of the entire society. It takes the balanced interaction between human society and the natural world as the starting point of development and takes man as a member of nature to re-understand and define the position of himself and his manufactured environment in the world [32]. Eco-architecture cannot be achieved by just a few architects, nor can it be accomplished overnight [29].…”

With the advancement of human science and technology, the continuous increase in the construction and functional improvement of campus buildings and school teaching infrastructure cannot avoid adverse impacts on the overall environment. Therefore, sustainability assessments of buildings are indispensable for the sustainable development of the surrounding region. The main goal of the sustainable design of campus buildings is to reduce the depletion of key resources, such as water and energy, as well as to lower carbon emissions; this, in turn, creates a safe and effective campus environment. Comprehensive assessments of campus buildings have become critical to achieving national and regional sustainability. Therefore, this study compiles a set of building construction indicators suitable for a framework for high school campus architecture and ecological development in Taiwan, conforms these indicators to climatic characteristics, and considers an evaluation model for sustainable building concepts. This research uses the Fuzzy Delphi Method (FDM) and the Fuzzy Analysis Hierarchical Procedure Method (FAHP) to gather data using expert questionnaires. We examine three relevant factors: (1) the main factor, campus space architecture, is the most important measure of sustainable buildings; (2) the second factor is the campus ecological environment; (3) the third measure of the sustainable campus buildings is a healthy environment. The top 20 elements of the sustainable campus building evaluation index were obtained through FAHP analysis, with an overall cumulative weight value of 81.06%. This research may provide a resource allocation reference for government bodies or the construction industry, assisting them in building sustainable buildings in the future.

“…Aljuwaisseri et al [9] investigated the impacts of intake water salinity and turbidity on the environmental impact. Researchers have addressed varying desalination process scenarios, including different gain ratios [19], multiple energy sources [10], [20], [21] and different capacities [22]. The effects of using renewable energy sources in DPs and their associated impacts on environmental loads have also been addressed within LCAs [19], [20], [23].…”

Sustainable water production is one of the top five challenges facing humanity within the upcoming decade; for arid regions, this challenge is aggravated. In this research, we evaluate the fastest growing technology in water treatment, reverse osmosis (RO), for both municipal wastewater treatment and seawater desalination to combat the challenges of water scarcity and climate change. We conduct a life cycle assessment (LCA) to evaluate the environmental impacts of municipal wastewater treatment and seawater desalination for a consistent functional unit using ISO 14040/44 standards. The modeling concept adopts a cradle-to-gate consequential paradigm. The life cycle inventory is based on field data collection from one of the largest wastewater RO plants worldwide, as well as reports, literature and ecoinvent database processes. The life cycle impact assessment is conducted on both the characterized and normalized levels using the ReCiPe method. The results are intended to assist policy-makers in better managing water resources. The study is applied to Kuwait but has wider repercussions.
