  • Carbon Footprint Assessment of a Novel Bio-Based Composite for Building Insulation
    Item type: Journal Article

    This research explores the carbon removal of a novel bio-insulation composite, here called MycoBamboo, based on the combination of bamboo particles and mycelium as binder. First, an attributional life cycle assessment (LCA) was performed to define the carbon footprint of a European bamboo plantation and a bio-insulation composite, as well as its ability to remove CO2 along its lifecycle at a laboratory scale. Secondly, the Global Worming Potential (GWP) was estimated through a dynamic LCA with selected end-of-life and technical replacement scenarios. Finally, a building wall application was analyzed to measure the carbon saving potential of the MycoBamboo when compared with alternative insulation materials applied as an exterior thermal insulation composite system. The results demonstrate that despite the negative GWP values of the biogenic CO2, the final Net-GWP was positive. The technical replacement scenarios had an influence on the final Net-GWP values, and a longer storage period is preferred to more frequent insulation substitution. The type of energy source and the deactivation phase play important roles in the mitigation of climate change. Therefore, to make the MycoBamboo competitive as an insulation system at the industrial scale, it is fundamental to identify alternative low-energy deactivation modes and shift all energy-intensity activities during the production phase to renewable energy.

    Indoor humidity significantly affects building occupants’ comfort, health, and well-being. Ideally, indoor relative humidity levels should stay within 40–60% to prevent respiratory irritation and the spread of mould and viruses. Conventionally, HVAC systems are used for indoor humidity control, but they have considerable environmental impact due to both the embodied emissions in the machinery and emissions during their operation. This study explores an alternative approach using low-carbon, hygroscopic, 3D-printed panels that regulate indoor humidity passively. Two types of panels are considered: one developed by ETH Zurich using a superhygroscopic geopolymer composite with a gyroid-based geometry, and the other designed by Politecnico di Torino using a hygroscopic clay composite with a multi-layered geometry. These designs enhance moisture buffering by exposing a large surface area of the materials to indoor air. Experimental results and tentative modelling approaches are discussed, comparing simulations with measured outcomes. This work highlights the need for accurate modelling strategies for representing the hygroscopic behaviour of 3D-printed components with complex geometries, using conventional dynamic hygrothermal simulation tools.
  • Identification of the two parameters controlling compressive strength of earth materials at dry state

    Earth is a non-standard material with composition linked to its geological past. Therefore, it can be seen as a resource with high variability, leading to a high range of earth material properties. This variation in its properties makes it difficult to master as raw materials for construction at an industrial scale. As an answer to this statement, this research aims to identify key parameters that help mitigate the impact of the fine fraction composition on the final properties of earth component. The research is conducted on known binders made with a constant ratio of different clays and quartz silt. It is shown that the compressive strength of fully dried earth binder is controlled by the dry density and the clay activity defined by the methylene blue value. The results obtained are promising for developing an optimized mix design strategy for poured earth application.

  • A multi-stakeholder engagement framework for material-building-city synergy through circular transformation
    Item type: Journal Article
    Bostancı, Hafize Büşra; Tanyer, Ali Murat; Habert, Guillaume (2024)
    Sustainable Cities and Society
    Scholars, industrial stakeholders, and governmental institutions are developing the circular economy paradigm. However, the emergence of multiple perspectives has challenged its implementation. As the industry that is the biggest contributor to the negative impacts on the environment, the construction industry stakeholders are paving the way for more sustainable as well as circular and regenerative construction by considering all actors in the system. Yet, the construction industry has a complex supply chain that requires clear strategies and stakeholder engagement across materials, buildings, and cities for efficient flows in the supply chain. Nonetheless, there is a need for improvement in the engagement of construction stakeholders for circular transformation. Therefore, this study aims to develop a multi-stakeholder engagement framework through circular transformation to guide the decision-makers for circular city governance. It has identified critical success factors by considering the construction stakeholders. The framework includes strategies at the micro (material), meso (building), and macro (city) scales to strengthen the material-building-city synergy. It's a significant step toward advancing circular city governance by bridging the gap between theoretical understanding and practical implementation and establishing a robust engagement for material-building-city synergy. The study employs a systematic literature review to extract strategies and natural language processing to analyze the strategies by topic modeling and defines critical success factors for multi-stakeholder engagement at multiscale. The outcome introduces the REVERT framework, bridging resource, envisagement, validation, entity, regulation, and technology, to facilitate a seamless transition by material-building-city synergy advancing circular city governance.
  • Effect of sulfidic mine tailings used as mineral admixtures on the hydration of common and alternative cements
    Item type: Journal Article
    Pires Martins, Natalia; Helser, Jillian; Plötze, Michael; et al. (2024)
    Materials and Structures
    In this work, we investigate the use of pyrite-rich tailings from an operational mine as mineral admixture in different cement matrices [Portland cement, calcium aluminate cement (CAC), and calcium sulfoaluminate cement (CSA)]. Hydration and microstructure changes were studied on cement pastes produced with a 30 wt% replacement of cement with tailings, up to 200 days. Based on our results, the effect of the tailings on the hydration of Portland cement is limited to a physical effect, and no sulfide-induced degradation is observed. In the CAC and CSA pastes, minor mineral phases present in the tailings chemically react, leading to changes in the mineral phase composition of CAC and CSA hydrated pastes. In addition, in all cement pastes studied, and more effectively in the CSA pastes, most of the metal(loid)s contained in the tailings were safely immobilized. Cement chemistry notation: C: CaO; A: Al2O3; F: Fe2O3; S: SiO2; S̅: SO3; c: CO2; H: H2O.
