Mycelium as a building material: current status and development perspective

Résumé

Bio-based materials as the alternatives to the current energy-intensive building materials represent a new trend in the construction industry, to replace concrete or insulation sections. In this context, mycelium is recently introduced as the base material of novel net-zero-energy insulation composites, which reduce embodied and operational energy of buildings. This review aims to present and discuss the current development status of mycelium composites and to envision the prospective roadmap of its evolution in the building industry. Outcomes of this study indicate that mycelium’s environmental footprints and embodied energy is significantly lower than traditional building materials and even some of its bio-based peers. Furthermore, due to its great insulation capacity, it offers a reliable capacity to be the alternative for traditional carbon emissive insulation materials, especially in severe climates, in which case insulation is indispensable. Mycelium’s hygric capacity is reported higher than other insulation materials in water absorption. In addition to the beneficial subsequent moisture buffering, there are also some challenges in shrinkage and durability, which are reviewed. There are numerous processing and fabrication methods for composites, each of which could affect the resulting physical properties that are discussed throughout different studies. Cutting-edge projects on the usage of growing organism in building materials are cited as the last part of this review.
