Towards net-zero with fast-growing biobased construction materials

Abstract

This review aims to bridge knowledge gaps in the use of biobased building materials in construction by critically analysing available scientific literature. We seek to inform stakeholders, promote sustainable practices, identify adoption barriers and highlight the opportunities provided by fast-growing biobased materials to achieve net-zero built environments. Through this review, we identify bamboo, hemp, straw, and mycelia as critical materials with substantial potential for carbon capture and storage. To achieve the net-zero built environment it will be necessary to create intersectoral synergies, specially between agricultural, forestry and construction. Our results indicate that the broad adoption of biobased materials is hindered by concerns related to durability, fire safety, cost, and standardized construction regulations. Nevertheless, these materials offer plenty of opportunities to valorize their local character and associated environmental services like their carbon storage potential. Thus, providing the foundation for the development of local regenerative intersectoral value chains.
