Vietnam: Trung Hieu Development Corporation has secured a five-year contract to use Betolar’s alkali-activated slag and fly ash-based concrete additive Geoprime. Trung Hieu Development Corporation plans to source the materials for Geoprime from local industrial side streams. Dow Jones Institutional News has reported that the move will eliminate 80% of raw materials CO2 emissions across its 120,000t/yr-worth precast concrete production capacity.

Betolar's Head of Asia Juha Pinomaa said "Vietnam is the world's third largest cement producer and fourth largest cement consumer, with 85Mt/yr. We estimate that the Vietnamese market represents significant commercial potential for us in the coming years due to the huge potential for cement replacement.” He concluded “We can promote the local circular economy and accelerate Vietnam's sustainable development efforts by directly offering cement-free alternatives. The Vietnamese steel and energy industry generates large amounts of steel slag and fly ash as side streams, which can be used for Geoprime-based concrete."

US: Switzerland-based Sika is starting up production at a new concrete admixtures plant at Stafford in Virginia that opened earlier in 2022. The 3950m2 facility has a production capacity of 50,000t/yr and two mixers with a capacity greater than 27,000l each. The unit is intended to serve markets in the Northeast and Mid-Atlantic regions along with the company’s existing concrete admixtures plant at Fairless Hills in Philadelphia.

Christoph Ganz, Regional Manager Americas said "This investment allows us to significantly expand our production capacity while creating the best possible conditions for continued growth in the North American market. Our concrete admixtures satisfy the construction sector’s most demanding requirements and make it possible to produce higher-performance, resource-saving concrete. Sika admixtures enable the realisation of critical infrastructure projects, are used in state-of-the-art high-rise construction, and help increase sustainability in megacities."

Germany: HeidelbergCement has joined EPEA’s Heidelberg Circular City Building Material Registry pilot project. The initiative uses EMEA’s Urban Mining Screening digital registry, which is able to estimate the composition of buildings based on building data. HeidelbergCement says that it will enable it to source construction and demolition waste for circular economic use in building materials production. This will support its ReConcrete 360° recycled concrete CO2 reincorporation project, among other projects. The initiative will turn Heidelberg into Europe’s first Circular City.

“Full circular economy and sustainable construction are central elements of our climate strategy,” said HeidelbergCement chair Dominik von Achten. “We are focusing on the life cycle assessment of our product concrete, including the processing of demolished concrete, and returning it to the construction cycle. By 2030, we want to offer circular alternatives for half of our concrete products.” Von Achten concluded “Together with the city of Heidelberg, also a pioneer in the area of climate protection, we want to use the Circular City project to demonstrate the enormous potential of concrete recycling for future urban construction.”

Finland: Betolar has patented a method for producing binder from the by-products of metal extraction. The method uses metallic effluent, sludge and dregs generated by the bioleaching of ores.

Chief innovation officer Juha Leppänen said “The ability to produce new solutions for the utilisation of sidestreams is essential to the functioning of our ecosystem. Betolar has a rapidly growing patent portfolio considering its age. We have already obtained approved patents for five inventions of ours.” He added “Waste materials, such as gypsum sludge, can also be used in other construction applications which will be of great value to Betolar's business in the future.”
