Germany: The Ministry for Economy and Climate Protection has presented HeidelbergCement with its German Climate and Environment Innovation Prize (IKU) for its ReConcrete-360° concrete recycling process. The process retrieves hardened cement paste from waste demolition concrete for use in place of limestone in clinker and cement production. The recycled material can also bind CO2 to act as a carbon sink.
Global research and development Wolfgang Dienemann said “With ReConcrete-360°, we have succeeded in developing a limestone substitute from demolished concrete that also allows us to use the carbon-containing exhaust gases from cement production. A small revolution with a big impact: In Germany alone, the CO2 savings potential of this process is 10Mt/yr. The IKU award underlines that we can be proud of our pioneering innovation.”
Mexico: Cemex aims for more than 50% of its sales cement and concrete to consist of Vertua reduced-CO2 products by 2025. In the first quarter of 2022, Vertua concrete accounted for 31% of Cemex’s concrete sales, while Vertua cements accounted for 34% of its cement sales.
CEO Fernando Gonzalez said “The ultimate objective of our Future in Action programme is to provide our customers with net-zero carbon products and solutions. Our Vertua products are an important step in this direction, designed to meet society’s demand for resilient and long-lasting buildings and infrastructure built with a lower carbon footprint.”
Poland: The Building Research Institute has issued environmental product declarations (EPDs) for Cemex Poland’s Vertua Classic and Vertua Plus concrete products.
Materials director Michał Grys said “For us, product certification is another important step towards sustainable construction and a sustainable future. EPD declarations provide our clients with additional confirmation of the properties of products offered by Cemex Poland. They also improve their chances of obtaining LEED or BREEAM certificates for their investments.”
