Development of GHG Emissions Curves for Bio-Concretes Specification: Case Study for Bamboo, Rice Husk, and Wood Shavings Considering the Context of Different Countries

Bio-concretes are receiving special attention in recent research as an alternative for climate change mitigation due to their low carbon footprints. Different bio-based materials can be used, e.g., wood shavings, bamboo, rice husk, and coconut. However, various methodological parameters influence the footprint of materials, especially bio-concretes, like biogenic carbon, amount dry matter, rotation period bio-aggregates, type cementitious materials. It is important have easier ways estimating using data easily available. This aims evaluate (1) different mixtures three bio-concretes (wood bio-concrete - WBC, bamboo BBC husk RBC), (2) development GHG emissions curves specification based on available (such density, biomass content, compressive strength). Based experimental data, was performed Life Cycle Assessment (LCA) methodology. In order extend findings this study, context following four countries evaluated: Brazil, South Africa, India, China. addition, replacement Portland cement Supplementary Cementitious Materials (SCMs) evaluated hypothetically. The results show that increase content by SCMs leads a radical decrease life cycle emissions. percentage critical factor reducing footprint. WBC better parameter. presented useful way estimate adapted other kinds countries.
