INSEE ECO Plus+ is a green cement launched by Siam City Cement (Bangladesh) Limited in 2024. Siam City Cement (Bangladesh) has secured the EBL Climate Change Action Award for its innovative approach to green manufacturing in Bangladesh. It is specifically engineered to withstand the aggressive salinity and corrosive soil conditions of Bangladesh’s coastal regions. By reducing clinker content to approximately 45–50 per cent through the integration of industrial by-products like slag and fly ash, the product achieves a 46 per cent lower carbon footprint than traditional Ordinary Portland Cement. It directly supports national climate commitments and global sustainability goals. Despite its low-clinker formulation, it provides superior durability, high surface resistivity, and enhanced chloride resistance. INSEE ECO Plus+ ensures a longer structural lifespan for infrastructure without compromising on compressive strength. Validated by rigorous scientific testing and technical partnerships, INSEE ECO Plus+ represents a transformative shift toward climate-smart construction and circular economy principles in the Bangladeshi market.
