This study investigates the potential of Australian desert sand as a partial replacement for river sand in concrete production and evaluates the performance of specimens confined with fibre-reinforced polymer (FRP) using a multi-scale experimental approach. Replacing 50 % of river sand with desert sand led to a slight reduction in compressive strength but improved tensile properties, which were attributed to a denser concrete matrix and reduced porosity. Microstructural analyses, including scanning electron microscopy (SEM) and micro-XCT, revealed significant decreases in pore size and volume for desert sand concrete (DSC), thereby enhancing the material compactness. FRP confinement provided a slightly greater strength enhancement for desert sand concrete (DSC) compared to normal concrete (NC), although strain enhancement was lower for DSC due to differences in the internal microstructure. Furthermore, existing FRP confinement models developed for NC demonstrated adequate accuracy in predicting the stress-strain behaviour of FRP-confined DSC, indicating no need for a new stress-strain model. These findings highlight the potential of desert sand as a sustainable alternative for concrete production.</div></div>","PeriodicalId":22097,"journal":{"name":"Sustainable Materials and Technologies","volume":"45 ","pages":"Article e01503"},"PeriodicalIF":8.6,"publicationDate":"2025-06-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144482405","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The biogenic CO₂ sequestration associated with camelina cultivation played a key role in reducing the overall greenhouse gas (GHG) emissions resulting from CMM's production. Results showed that replacing dichloromethane with greener solvents alternatives, such as 2-methyltetrahydrofurane (Me-THF) and hexane, adressed not only environmental, health, and safety concerns but also improved yields by up to 9 %. The study also indicated the significance of recycling alternative solvents, demonstrating significant reductions in the environmental impacts, particularly in ozone and fossil fuel depletion categories. Despite variations in scenarios using alternative solvents, the minimum selling price (MSP) remained steady at approximately $61 per kg, maintaining competitiveness with petroleum-based alternative while offering a lower environmental footprint. The MSPs were primarily influenced by fluctuations in raw material prices and total capital investments, with only a moderate reductions observed as production scales up from 1.6 to 105 kton per year. Notably, this study demonstrated the viability of biobased monomers as alternatives to petroleum-based butyl acrylate, with a 23 % reduction in GHG emissions attributed to CO₂ sequestration during camelina cultivation. Additionally, solvents recycling significantly reduced most environmental impacts, achieving a 70 % and 12 % decrease in ozone depletion and fossil fuel depletion categories, respectively.

First, Cu nanopillars (∼160 nm in diameter) are self-assembled on Cu foil through a galvanic displacement reaction. These pillars are subsequently transformed into edge-split Cu(OH)₂ nanoneedles as thin as ∼30 nm by ammonia-assisted electro-oxidation in an aqueous electrolyte.

This hierarchically porous, ultrafine architecture markedly enhances electrochemical kinetics. As a result, the CuO nanoneedle anodes exhibit excellent rate capability and cycling stability, delivering specific capacities of 973 mAh g⁻¹ at 0.2 A g⁻¹ and 663 mAh g⁻¹ at 5 A g⁻¹. When paired with activated carbon cathodes, the LIC devices demonstrate outstanding rate performance, achieving an energy density of 110.1 Wh kg⁻¹ at 2C and retaining ∼40 % of their capacity at an ultrafast rate of 60C.

Despite their potential, significant challenges remain in developing a dyeing method that is zero-effluent, economical, industrially feasible, and eco-friendly.

The dyeing performance and colourfastness properties of the fabrics dyed by various sustainable dyeing methods have been compiled and compared. Supercritical carbon dioxide (scCO₂) and decamethylcyclopentasiloxane (D5) have emerged as the two most promising green alternative dyeing media.

Conversely, scCO₂-based dyeing is primarily suitable for dyeing polyester fibres with disperse dyes but is unsuitable for dyeing cotton, wool and other fibres as the dyes used in their dyeing are not soluble in scCO₂ medium.

This study compares the mechanical performance and environmental impact of primary and recycled high pressure die casting AlSi10MnMg (EN AB 43500) alloy under as-produced and heat-treated conditions. Samples were extracted from a die-cast automotive component and subjected to annealing and an optimized T6 heat treatment to balance strength and ductility.

This similarity justifies the comparable mechanical behavior of the primary and recycled alloy, characterized by limited ductility in the as-produced condition, often insufficient for safety-critical structural components. Heat treatments significantly improved ductility, increasing it by 40–50 % after annealing and nearly doubling it after T6 due to the fragmentation, spheroidization, and coarsening of the eutectic Si. However, the microstructure change reduces strength by a third after annealing and by 20 % after T6, ultimately influencing the final fracture mechanisms.
