📄 Abstract（原文）
The construction sector is a major contributor to global carbon emissions, with cement production alone responsible for 5–8% of anthropogenic emissions. To address this, we introduce a new version of biopolymer-bound soil composite which we term, Engineered Biopolymer Composite (EBC), a cement-free building material that combines lignin and methyl cellulose to create a structural material with compressive strength comparable to concrete. EBC achieves compressive strength up to 25 MPa—representing up to a 400 % improvement over previous lignin-based biopolymer soil composites. These improved material properties are attributed to improved intermolecular interactions, esterification of lignin, and increased particle-to-particle contact due to increased pre-compaction. EBC is carbon-negative, sequestering biogenic carbon in construction applications, and is cost-competitive with conventional concrete. These findings demonstrate EBC’s potential as a sustainable, high-performance material for structural and non-structural construction applications.
