Abstract

The construction industry is under pressure to address climate change and resource scarcity, leading to a growing interest in emerging biobased materials. This research focuses on microbial bricks through a life cycle assessment (LCA) based on ISO 14042 standards and CML2001 impact categories, examining various environmental criteria across a defined system boundary: Manufacturing. The findings highlight the positive potential of biobased materials in contributing to a greener supply chain management for the construction industry, even more than clay that we know as an earth (green) material. The biggest differences lay in the use of fossil fuels, electricity, transportation, and the assembly process. By addressing challenges and leveraging opportunities, these materials can lead to a more resilient and ecologically conscious sector, in alignment with the sustainable development goals (SDGs) defined by the United Nations (UN). The aim of this study is to stimulate additional dialogue and cooperation among academic and industrial participants to promote sustainable advancements in construction materials and manufacturing methods, transcending mere superficial green initiatives.
