Abstract
This study examines the environmental footprint of the cement industry and the potential transition toward a more sustainable and competitive operational model. Cement production is a major global source of CO₂ emissions, primarily due to limestone calcination and fuel combustion. The research analyzes emission sources, evaluates different cement types, and reviews technological and strategic solutions implemented worldwide to reduce environmental impact.
The methodology includes life‑cycle assessment (LCA), analysis of Environmental Product Declarations (EPDs), comparison of cement categories (CEM I–IV), and benchmarking of three major groups: TITAN, LafargeHolcim, and HeidelbergCement. Economic data, sustainability (ESG) indicators, and levels of adoption of innovative solutions—such as CCUS technologies and 3D concrete printing—are also examined.
Findings show that blended cement types (CEM II–IV) significantly reduce carbon footprints, with CEM III achieving the lowest emissions. Companies adopt combined strategies such as increasing alternative fuels, reducing clinker content, and implementing CO₂ capture and storage (CCS). TITAN’s “Hephaestus” project is highlighted as a large‑scale CCS initiative aiming to capture 1.9 million tons of CO₂ annually and produce low‑carbon cement.
Overall, the decarbonization of the cement industry requires technological innovation, economically viable solutions, and strategic partnerships. The adoption of low‑carbon products, enhanced circular‑economy practices, and gradual implementation of CCUS technologies form the foundation for achieving sustainability goals and climate neutrality by 2050.
