Evaluating the Structural and Environmental Performance of Bio-Based Construction Materials for Green Buildings

Numerous circular start-ups engaged in the bio-construction sector develop novel substances and building goods, such as plant-based insulation supplies, bio-bricks, thermo-acoustic insulating sheets, screeds, and materials. They employ local agricultural products, like hemp, and by-products, including wheat straw, rice straw, rice husks, and food scraps, as substitutes for traditional construction supplies, goods, and procedures. In some instances, these goods are accredited with a Declaration of Environment or by the accreditation unique to bio-construction materials, providing several advantages, including technical, aesthetic, ecological, health, social, and comfort benefits. This research delineates the identified Construction Supply Units (CSUs)functioning in the bio-construction sector, detailing the features of their operations and the bio-materials and goods they provide. The findings of the literature study on ecological information on certain bio-materials and goods are provided and analysed. This information will be instrumental in advancing subsequent phases of the comprehensive research, specifically the Life Cycle Assessment (LCA) of the bio-construction materials and goods from the chosen CSUs. The present study has provided preliminary findings from visualizing the building industry, qualitative interviews, and literature reviews.
