| Abstract Scope |
Natural fiber-reinforced cementitious composites have been investigated as sustainable alternatives for reducing the environmental impact of construction materials. However, their sustainability depends not only on renewable raw material use, but also on processing, durability, transportation, end-of-life scenarios, and performance during service. This study reviews literature addressing the environmental assessment of cementitious composites incorporating natural fibers and lignocellulosic residues. Studies related to circular economy, life cycle thinking, carbon footprint reduction, resource efficiency, and replacement of conventional materials were analyzed. The reviewed literature indicates that natural fibers can reduce reliance on non-renewable resources, valorize agro-industrial residues, and contribute to lower-impact building products. Nevertheless, short service life, intensive chemical treatments, moisture-related degradation, and limited standardization may reduce environmental advantages. Therefore, sustainability assessment should integrate mechanical performance, durability, local availability, processing requirements, and end-of-life options to support the responsible development of natural fiber-reinforced cementitious composites. |
