Cemex opens Tunjuelo Circularity Centre
13 December 2022Colombia: Cemex has announced the launch of the Tunjuelo Circularity Centre at its former Tunjuelo quarry near Bogotá. Having rebuilt parts of the 50m-deep quarry with demolition waste, Cemex will now work on its ecological restoration, while continuing to receive excavation waste for reconstruction of the ground. It will meanwhile divert demolition waste deliveries for recycling in aggregate production. In Bogotá, Cemex has launched an initiative for urban construction partnerships in collaboration with local authorities. It will also collect municipal solid waste (MSW) there for use in its cement production and collect its used plastic cement bags for recycling in building materials production.
Cemex’s Colombia and Peru president Alejandro Ramírez said "This is a pioneering model for Cemex in the construction materials industry globally, which we aim to position as a benchmark for circularity within the sustainable development of large cities in Colombia and the world. A piece of land that supplied materials for Bogotá's development for decades has received construction and demolition waste for its redevelopment and was transformed into a green area to the south of the city, an epicenter of the circular economy and an opportunity for urban development for the capital city of Colombia."
Fletcher Building’s concrete division joins GCCA
09 December 2022New Zealand: The Global Cement and Concrete Association has welcomed Fletcher Building’s concrete division as its first member from Oceania. Scoop News has reported that the concrete’s division’s business spans the entire concrete value chain, including 26 limestone and aggregates quarries and 80 ready-mix concrete batching plants. Its cement subsidiary Golden Bay Cement operates the 0.9Mt/yr Portland cement plant in Whangārei, New Zealand.
Fletcher Building concrete division CEO Nick Traber said "Fletcher Building firmly believes we can play a significant part in a carbon zero and circular future. Our Golden Bay EcoSure cement is one of the lowest-carbon cements in the world already, with 13 - 22% less embodied carbon than imported products. We believe having access to the global research and knowledge from the GCCA will help us improve this further and continue to lead Australasia in best practice decarbonisation of the built environment."
Thomas Gruppe acquires Opterra Zement and Opterra Beton from CRH
26 October 2022Germany: Ireland-based CRH has agreed to sell its subsidiaries Opterra Zement and Opterra Beton to Thomas Gruppe. Thomas Gruppe expects to complete its acquisition of the businesses later in 2022. Opterra Zement owns the 1.4Mt/yr Karsdorf, Saxony-Anhalt, cement plant and 0.5Mt/yr Sötenich, North Rhine-Westphalia, grinding plant, the latter of which is closed. Opterra Beton operates the Neufahrn, Bavaria, ready-mix concrete batching plant.
Thomas Gruppe said "For years, we have been pursuing a steady and long-term growth course in the field of cement and precast and ready-mix concrete. In the cement segment, our competitive position improved significantly with the purchase of the Erwitte (North Rhine-Westphalia) plant in 2017. Together with the grinding plant in Dorndorf (Thuringia), we have achieved a significantly larger area coverage in Germany, and also in the Netherlands, and benefit from synergy effects." It continued "We would like to continue on this growth course. An opportunity like the one to take over the cement plant in Karsdorf does not come often. The Karsdorf plant, with its gigantic limestone deposits, its market position of well over 1Mt/yr of cement and its experienced team, enables us better to supply our customers, and to leverage improvement potential. In addition, Karsdorf is of sufficient size for us to implement CO2 separation technology in its production of clinker for the Dorndorf grinding plant." Thomas Gruppe concluded "We are convinced that cement will become a clean building material and believe in its future."
US: The Global Cement and Concrete Association (GCCA) has signed an international partnership agreement with the American Concrete Institute (ACI). Under the agreement, the partners will collaboratively develop and disseminate information on concrete production and its use in construction, with a view to advancing best practices in sustainability.
The ACI said "ACI cooperates closely with our international partners, benefitting everyone in the global concrete community. ACI looks forward to working with the GCCA towards a future where everyone has the knowledge needed to use the latest concrete technologies effectively to meet the demands of a changing world."
Pelješac Bridge project uses Cemex's Vertua reduced-CO2 cement
21 October 2022Croatia: Cemex supplied 37,000t of cement for construction of the new Pelješac Bridge on the Dalmatian coast. Cemex says that the 2.4km-long bridge has connected Southern Croatia to the rest of the country, eliminating the need to cross in and out of Croatia over an international border when travelling by land. Almost all of the cement used in the project was Cemex's Vertua brand reduced-CO2 cement product.
Cemex's Europe, Middle East, Africa and Asia president Sergio Menendez said “Cemex has been a proud contributor to the development of Croatia, and we are very pleased to participate in one of the largest infrastructure projects in the region. Our Vertua products are designed to meet society’s demand for resilient and long-lasting buildings and infrastructure, built with a lower carbon footprint.”
Seratech's carbon-neutral cement wins Obel Award 2022
10 October 2022UK: Denmark-based architecture fund Henrik Frode Obel Foundation has named Seratech as winner of its Obel Award 2022. The award recognises architectural contributions to global development. Seratech has developed an olivine-based composite cement produced using CO2 from flue emissions, which can sequester double the CO2 of ordinary Portland cement (OPC). When used as 40% of a blend with OPC, it is able to completely offset the emissions of concrete production.
Team member Barnaby Shanks said "The beauty of the idea is that you can just use it as normal concrete. There are other carbon-neutral materials, but they can be limiting because they can only be precast, cured in a lab in special conditions and shipped elsewhere. We want people to retain the freedom to use concrete the way that they are used to. We don’t want to limit people in any way because we’ll just lessen the amount of impact we can have."
Cemex UK purchases 10 reduced-CO2 tipper trucks
01 September 2022UK: Cemex has bought 10 Volvo 460 8x4 tipper trucks for use at its Angerstein Wharf aggregates depot in Greenwich. From there, the trucks will deliver sand and aggregates all around London. The trucks’ bodies are made of lightweight aluminium, and they conform to Euro 6 emissions standards. This corresponds to 80% NOx emissions reduction and 50% particulate emissions reduction compared to Euro 5 standards.
Cemex UK fleet engineering manager Nigel Ponton said “The addition of these new trucks to our fleet will enable us to better meet customer demand, safely and efficiently. Safety is the number one focus whenever we add new trucks to our operation and these Volvos tick every box in that respect.” Ponton continued “These trucks will all be working in busy streets across London so it’s imperative we provide our drivers with the best tools possible to do the job and help protect any vulnerable road users. Moreover, thanks to the improved fuel efficiencies and enhanced payload these new Volvos are the most sustainable vehicles we’ve ever had and will help decarbonise our delivery footprint.”
Germany: Dyckerhoff’s Dillingen ready-mixed concrete plant is the company’s first unit to be awarded the R module of the Concrete Sustainability Council (CSC). The unit has been using recycled aggregates in the standardised proportions and types since August 2021 and now customers and clients can have the certified sustainable concrete counted as part of building certifications. The recycled aggregate used in the Dillingen plant comes from a recycling company in the immediate vicinity, so there are no transport costs, which, in addition to the aspect of resource conservation, also contributes to the avoidance of transport-related CO2 emissions.
