This paper considers the design of RWH systems under long-term uncertainty in precipitation and demands. In this work, we formulate and solve a multi-objective stochastic optimisation problem that allows explicit trade-offs under uncertainty, maximising system efficiency and minimising deployment cost. We use the yield after spillage (YAS) approach to incorporate the physical and operational constraints and the big-M method to reformulate the nonlinear minmax rules of this approach as a mixed-integer linear programming (MILP) problem. By posing a risk averseness measure on efficiency as a conditional value at risk (CVaR) formulation, we guarantee the designer against the highest demand and driest weather conditions. We then exploit the lexicographic method to effectively solve the multi-objective stochastic problem as a sequence of equivalent single-objective problems. A detailed case study of a botanical garden in Amsterdam demonstrates the framework’s practical application; we show significant improvements in system efficiency of up to 15.5% and 28.9% in the driest scenarios under risk-neutral and risk-averse conditions, respectively, compared to deterministic approaches. The findings highlight the importance of taking into account multiple objectives and uncertainties when designing RWH systems, allowing designers to optimise efficiency and costs based on their specific requirements without extensive parameterisation.</div></div>","PeriodicalId":74689,"journal":{"name":"Resources, conservation & recycling advances","volume":"26 ","pages":"Article 200254"},"PeriodicalIF":5.4,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143844768","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study addresses these gaps by employing System Dynamics Modelling (SDM) to capture a more nuanced understanding of the heterogeneity of decommissioned panels. The findings reveal significant discrepancies between projections from conventional static models and those generated by the developed model, underscoring the need for more adaptive forecasting methods that account for temporal variations and the evolving characteristics of decommissioned panels.

It assesses supply chain risk (two stages: mining, processing) and economic importance for twelve materials representing infrastructure, battery, specialty, and other materials. Our analysis reveals distinct regional differences: China faces greater supply risk at the mining stage, primarily due to its reliance on imported raw materials for certain minerals, while the United States experiences higher supply risk at the processing stage, stemming from limited domestic processing capabilities. The EU and Japan exhibit higher supply risks overall than both the US and China, largely because of limited domestic production capacities. Japan has the highest number of materials—eight out of twelve—with both high supply risk and economic importance. Materials with the greatest difference in criticality among regions are rare-earths and aluminum at the processing stage, where processing bottlenecks and concentration of processing facilities heighten supply risks, and lithium, nickel, and cobalt at the mining stage, due to geographic concentration of mining activities and rising demand driven by battery production. These findings highlight the necessity for region-specific strategies to address supply chain risks, such as diversifying import sources, investing in mining/processing infrastructure, and stockpiling.</div></div>","PeriodicalId":74689,"journal":{"name":"Resources, conservation & recycling advances","volume":"25 ","pages":"Article 200250"},"PeriodicalIF":5.4,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143091895","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Thus, for the first time, this paper is aimed at developing a cost-effective, green, and novel technology for the extraction of oil from date pits using protic ionic liquids. The date pits of eight distinct varieties were structurally characterized, determining their composition of oil (7.6–10.9%), carbohydrates (80.8–84.6%), protein (4.8–8.8%), and ash (1.1–1.7%) based on dry biomass. The quality of oil across these date pits was found to be comparatively similar and well-suited for biofuel production, with oleic, lauric, myristic, and palmitic acid being the most abundant constituents. The screening of six unique protic ionic liquids indicated that Triethylammonium dihydrogen phosphate [TEA][H<sub>2</sub>PO<sub>4</sub>] exhibited the highest oil extraction of 91.3 mg/g biomass (84% of total oil) from Majdool dates. The investigation of process parameters disclosed that temperature significantly affected oil extraction performance, whereas the reaction duration's impact was found to be minor. The recycling and reuse of [TEA][H<sub>2</sub>PO<sub>4</sub>] for the extraction of oil from Majdool date seeds throughout four cycles were promising in terms of performance stability, thereby promoting process viability.

The objective is to determine a gypsum mixture, incorporating the maximum amount of waste, with suitable mechanical properties, workability and consistency for industrial replication. The research studies the physical and mechanical properties of the new products. During the manufacturing phase of the new plasters, it is reported that citric acid needs to be added to the mixtures to ensure good workability and to delay the setting time. Without pre-calcination, gypsum mortars with recycled ceiling tile show a 7 to 10 % reduction in bulk density, compared to the reference plaster. Only two of the four samples tested meet the mechanical requirements, with strengths 35 and 60 % lower than those of the control mixture.

This can be explained by sludge's composition that consists of more than 80% by mass of the elements: silicon, aluminum, iron and calcium. It should be noted that the predominance of these elements is related to the type of input used in water purification and the characteristics of the raw water collected. The mineralogical composition of WTPS is seasonally predominated by quartz and kaolinite.

Hence, this study aims to develop a framework that shows how training can influence project designers’ attitudes and behaviour towards the optimal use of PwRC through two research questions: (a) what are the factors that influence to change the attitude and behaviour, (b) what are the existing theories and models that support the attitudes and behavioural changes, using a systematic literature review. The review found that changing attitudes and behaviour towards the optimal use of PwRC is influenced by psychological factors, although economic and sociological factors do also have an impact. Of these psychological factors, attitude, knowledge, perceived behaviour control, and subjective norms are more frequently examined. From the economic factors, economic benefits and from sociological factors, collaboration and communication are the primary considerations. The review also suggests that the theory of Planned Behaviour and the Extended Theory of Planned Behaviour are the most widely used theories in this respect.
