Currently, the production of concrete accounts for 8 % of global carbon emissions. Therefore, alternatives to concrete must be developed, to reduce its use in the future. New construction materials will help to facilitate a green transition as envisioned in global climate initiatives. Materials such as lignin are ideal, as they can be implemented with little additional cost to manufacture construction materials. We introduce a novel material, lignin-based biopolymer-bound soil composite (BSC), which is similar to other BSCs using other types of biopolymers. In addition, a design methodology is presented, which allows the manufacture of lignin-based BSCs with tailored characteristics. Two kinds of lignin — hydrolysis lignin and alkali lignin — were investigated, with five mix designs developed for each type of lignin. The lignin-based BSCs were found to have compressive strength ranging from 1.6–8.1 MPa, which allows them to be implemented in non-structural construction applications. Ultimate compressive strength, density, and other parameters were measured, leading to the development of design relationships for lignin-based BSC. The design relationships presented in this study will help introduce lignin-based BSC as a sustainable form of construction.</div></div>","PeriodicalId":100254,"journal":{"name":"Cleaner Materials","volume":"14 ","pages":"Article 100279"},"PeriodicalIF":0.0,"publicationDate":"2024-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142746266","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}

This paper is the first to investigate the critical interface between demolishers and producers. In particular, demolishers are crucial for the potential to valorize reclaimed construction wood as they are the gatekeepers of the materials. We apply an existing framework, conceptualized through a systematic literature review, to the case of a Danish shed producer and their collaboration with demolishers. Our data foundation includes qualitative data from semi-structured interviews with industry stakeholders and quantitative financial data on conventional as well as selective demolition. Through the analysis of material, information, and financial flows of reclaimed wood, this paper identifies inhibitors to these flows and reveals that producers can address the majority. Since responsibilities for reprocessing, transportation, and storage require clarification, making agreements for (1) reprocessing and (2) transportation, potentially facilitated by (3) a digital platform can support the producer in overcoming these inhibitors. Even though we show that selective demolition can be financially attractive for demolishers, our findings call for additional supportive regulation of tender practices. Further, we coin the concept of reversed value proposition as RLSC necessitate a reversed understanding of value creation. Overall, this paper contributes empirical evidence to the existing framework, extends it by adding inhibitors and flows, and suggests an extension with platform thinking to support the implementation of RLSC.</div></div>","PeriodicalId":100254,"journal":{"name":"Cleaner Materials","volume":"14 ","pages":"Article 100276"},"PeriodicalIF":0.0,"publicationDate":"2024-11-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142706613","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}

Integrating thermochromic properties into asphalt could provide a sustainable solution to mitigate UHI while maintaining the necessary mechanical performance. This research reviews the literature, scientific advances, gaps, and future perspectives on thermochromic (TCM) asphalt mixtures through bibliometric analysis and systematic review. The analysis highlights that thermochromic asphalt has recently gained significant scientific interest, with an increasing number of publications from 2013 to 2023. Notably, Hunan University in China has emerged as a leading contributor to thermochromic-related publications. The findings identify the wet method as a prevalent form of thermochromic functionalization, with 4–6% TCM content considered most suitable for thermal performance. Adding TiO<sub>2</sub> improves optical characteristics due to its high reflectance in the Near-infrared solar spectrum. Studies using TCM binders typically show asphalt mixtures with better resistance to rutting and cracking, likely due to enhanced thermoregulation. The key knowledge gaps identified include the lack of consistent procedures across studies, the feasibility of scaling lab-based methods to field applications, and the need for experiments to assess their impact on road safety, surface characteristics, and the durability of thermochromic properties over the pavement’s service life. This review highlights the promise of TCM for urban heat management and emphasizes the importance of additional research to achieve the ideal balance between thermal and mechanical properties.</div></div>","PeriodicalId":100254,"journal":{"name":"Cleaner Materials","volume":"14 ","pages":"Article 100273"},"PeriodicalIF":0.0,"publicationDate":"2024-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142434000","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}
