The construction industry strives for climate neutrality by 2045-2050 with a focus oncollaboration, innovation, and efficient use of resources to reduce greenhouse gasemissions and promote sustainable construction methods. This degree project from theBuilding Engineering program at Halmstad University investigates energy efficiency andoptimization of the asphalt manufacturing process, especially heat storage in silos, incollaboration with Skanska Industrial Solutions.The study applies qualitative methods, including interviews with experts and visits to anasphalt plant in Sperlingsholm, Halmstad. The theoretical framework includes sustainabledevelopment, sustainable road networks, hot mix asphalt (HMA), and design andmaterials for heat storage silos.The research methodology included data collection, interviews, field visits andsimulations with COMSOL Multiphysics to analyse temperature changes and comparedifferent silo design options. Autodesk AutoCAD was used to create 2D drawings.The results emphasize energy efficiency and sustainability in asphalt manufacturing, withthe potential to reduce greenhouse gas emissions through optimized silo design andinsulation. Specifically, the implementation of heat storage silos shows a significantreduction in oil consumption and 𝐶𝑂2 emissions. The study further recommends researchfor validation and improvement in real production environments and contributes withinsights into sustainable construction methods, underscoring the need for technologicalinnovation to meet the environmental challenges in the construction industry.
