1.1 What are Bio-Based Building Materials?

Bio-based materials are renewable resources that originate from biological sources. Unlike fossil-fuel-derived materials, they are part of a natural carbon cycle, meaning they absorb carbon dioxide during their growth. When responsibly sourced and processed, they have a significantly lower environmental impact. Key characteristics include:

• Renewability: They can be grown and replenished within a human lifespan.
• Low Embodied Energy: Less energy is consumed during their production, transportation, and construction compared to traditional materials.
• Carbon Sequestration: As plants grow, they absorb carbon dioxide from the atmosphere. When used in buildings, this carbon is stored, helping to mitigate climate change.
• Improved Indoor Air Quality: Many bio-based materials are non-toxic and breathable, contributing to healthier indoor environments.
