This report, prepared by Arup and StopWaste, explores the potential of various biogenic building materials that can be used in industrialized construction to support low carbon and circular economy solutions in the buildings sector. The research focuses on renewable plant-based materials that sequester and store carbon and can biodegrade back into the earth.

The report provides brief summaries of a wide range of materials, including straw, bamboo, fire-risk wood, hemp, agricultural byproducts, and more. It then dives into detailed technical information on the four materials identified as having the highest potential: straw, bamboo, fire-risk wood, and hemp. For each of these materials, the report covers carbon storing capacity, material description, current manufacturers, technology readiness levels, and specific product applications.

The research highlights the opportunities these biogenic materials present for sustainable construction in California and beyond, as well as the challenges and support needed to scale their adoption in the market. With new regulations like AB2446 incentivizing the use of biobased building materials, this report provides timely insights for the buildings industry to meet carbon reduction goals through regenerative material solutions.
