Lotte Engineering & Construction (Lotte E&C) announced on November 12 that it has developed a CO2-injected floor mortar technology, which has been applied for the first time at construction sites. This development is a result of collaboration between Lotte E&C and Halla Cement, aiming to significantly contribute to reducing carbon emissions in the construction industry. The "CO2-injected floor mortar" technology involves capturing high concentrations of carbon dioxide produced during industrial processes and injecting it into mortar mixes.
Utilizing this technology increases the mortar's density, enhances its strength by about 5%, and reduces cement usage by 3%. Consequently, this effectively reduces carbon emissions, generating an environmental impact equivalent to planting approximately 11,360 thirty-year-old pine trees when applied to a 1,000-unit apartment complex. This technology was developed as part of a national project supported by the Ministry of Trade, Industry and Energy and the Korea Institute of Energy Technology Evaluation and Planning.
The research involved various entities, including Lotte E&C, Halla Cement, and Eugene Corporation, alongside academic institutions like Seoul National University and Pukyong National University, as well as research institutes such as the Korea Limestone Research Institute, the Ceramic Research Institute, and KCL. Following quality verification through testing conducted in August this year, Lotte E&C began implementing this technology on-site. "Starting with the application of the CO2-injected floor mortar technology, we plan to extend carbon reduction technologies in the concrete sector as well," an official from Lotte E&C.
"We aim to establish ourselves as a leading company in carbon-neutral technology within the construction industry.".
