We propose a five-step (D5) digital circular workflow that integrates these digital innovations towards reuse, validated through real-world case studies. We assessed a variety of digital tools for enhancing the reuse of construction materials, including digital product passports, material classification assisted by artificial intelligence (AI), reality capture, computational design, design inspired by generative AI, digital fabrication techniques, extended reality, and blockchain technology. Using action research through a multiple case study approach, we disassembled several buildings that were set for demolition and subsequently designed and executed construction projects using the salvaged materials. Our findings indicate that digital transformation for detection, disassembly, distribution, design, and finally deployment significantly support the application of circular economy principles. We demonstrate the potential of the proposed workflow for industry implementation and scalability.","PeriodicalId":471646,"journal":{"name":"npj Materials Sustainability","volume":" ","pages":"1-15"},"PeriodicalIF":0.0,"publicationDate":"2024-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11530372/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142570907","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}

The addition of clay accelerates hydration kinetics and promotes the formation of more cross-linked calcium–(sodium) alumino silicate hydrates (N-A-S-H and C-(N)-A-S-H). This contributes to early strength and a 25% reduction in total shrinkage after 60 days. Although ACC promotes higher carbon sequestration and increases 1-d compressive strength by 13%, it leads to severe decalcification of 25S-AAM after 365 days of natural exposure, resulting in coarsening of the pore structure in the mesoporous size range of 10–100 nm. Due to a relatively low Ca/Si ratio, 25S-AAM is more adversely affected by natural carbonation during the 365-d exposure period than the control (without clay). In summary, ACC is not recommended for earth-based AAM products especially if they are applied for outdoor constructions.","PeriodicalId":471646,"journal":{"name":"npj Materials Sustainability","volume":" ","pages":"1-21"},"PeriodicalIF":0.0,"publicationDate":"2024-10-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.com/articles/s44296-024-00040-w.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142377234","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}

We hypothesised that soil pH has a greater impact on the development of Al-organomineral complexes in volcanic soils compared to non-volcanic soils, in the latter, the silt and clay fractions play a crucial role. Soil pH >4.5 strongly influenced the formation of Al-organomineral complexes in volcanic soils, while an increase in allophane content led to a decrease in SOC. Ultisols with more crystalline clays, such as halloysite and disordered kaolinite, the pH had a weaker impact and there was no effect on non-volcanic soils. Instead, a positive correlation (R2 = 0.63, p < 0.01) was found between silt and clay and SOC in non-volcanic soils, supporting our second hypothesis. Soil pH played a significant role in the interplay between Al-organomineral complexes and allophane formation, while crystalline mineralogy has a direct effect on SOC levels in non-volcanic soils.","PeriodicalId":471646,"journal":{"name":"npj Materials Sustainability","volume":" ","pages":"1-7"},"PeriodicalIF":0.0,"publicationDate":"2024-09-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.com/articles/s44296-024-00038-4.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142174393","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}

However, the intricate nature of lignin and the ensuing complexity of its aggregation behaviour, coupled with the plethora and diversity of techniques used, still requires systematic attempts to unify the scattered and at times contradictory data. This effort attempts to enumerate the various parameters affecting self-assembly phenomena of lignins by critically considering the science behind its solvation behaviour in organic solvents, in aqueous media, and its eventual self-assembly in forming nano-systems. Finally, knowledge gaps that cause present limitations and potential future efforts, are identified so as to arrive at a thorough comprehension of these phenomena.","PeriodicalId":471646,"journal":{"name":"npj Materials Sustainability","volume":" ","pages":"1-9"},"PeriodicalIF":0.0,"publicationDate":"2024-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.com/articles/s44296-024-00037-5.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142160307","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}

These polymers comprise natural building blocks, such as amino acids and glycans, which ensure their true environmental benefits at the end of their lifecycle. For example, cellulose is a highly sustainable material with many excellent properties, including renewability, biodegradability, and versatility in its functionality. It can be used in various forms, such as textiles, packaging materials, and building insulation. Here, we studied advanced cellulosic materials produced by blending or creating bi-composites with biomanufactured proteins inspired by squid ring teeth (SRT). Biomanufactured proteins can be synthesized in larger quantities, have a controlled production process, be modified to create desirable variants, and their production can be scaled up or down. Specifically, we engineered recombinant SRT proteins to have high electrostatic charge, induce crystallinity, and provide polar hydroxyl groups, which enhances cellulosic materials’ triboelectric response. The triboelectric voltage of blend triacetate and cellulose fibers increased by 72–108% and 49–57%, respectively, with a protein content of 10% wt. Furthermore, coating proteins on cellulosic fibers to create bi-composite fibers is a highly effective method for doubling (200%) the triboelectric performance. This finding has important implications for developing sustainable triboelectric materials and producing advanced materials using biomanufacturing.","PeriodicalId":471646,"journal":{"name":"npj Materials Sustainability","volume":" ","pages":"1-11"},"PeriodicalIF":0.0,"publicationDate":"2024-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.com/articles/s44296-024-00035-7.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142123439","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}
