South Africa: Saudi Arabia-based ACWA Power and Industrial Development Corporation of South Africa (IDC South Africa) have partnered to explore the development of green hydrogen infrastructure opportunities in South Africa. Together, they will aim to accelerate the country's transition into a green hydrogen economy across industries including cement production. ACWA Power projected the potential value of developments at US$10bn.
South Africa is committed to achieving net zero CO2 emissions by 2050.
ACWA Power's vice chair and chief executive officer Paddy Padmanathan said "As a company that is driving the energy transition, ACWA Power is proud to work closely with the IDC, with whom we share a robust working history, and today we are delighted to take our collaboration further. I am confident that our expertise in developing mega-scale green hydrogen projects in other geographies will enable us to successfully create a new avenue of sustainable energy generation - one that will pave the path to further progress.”
Spain: Brazil-based Votorantim Cimentos' Córdoba, Niebla and La Araña cement plants in Andalusia are at the centre of a planned Euro1bn decarbonisation project by the company. Votorantim Cimentos will publish details of its plans, which include renewably powered green hydrogen and biofuels production, in early 2023.
Votorantim Cimentos Europe, Asia and Africa CEO Jorge Wagner said "We need agility with the administration, because the investments are stratospheric and long-term. We want to obtain subsidies, taking advantage of European funds." He concluded "We have the opportunity to carry out a very beautiful project in Andalusia and beat the Americans."
Spain: Cementos Portland Valderrivas plans to make Euro6m-worth of investments in its Alcalá de Guadaira cement plant in Seville. The funds will go towards the construction of a refuse-derived fuel (RDF) line to help reduce the plant's petcoke consumption, as well as the renewal of the plant's mining licence for its quarry.
Ciments Calcia commences Euro285m Airvault cement plant upgrade
17 October 2022France: Heidelberg Materials' subsidiary Ciments Calcia has laid the foundation stone for its construction of a Euro285m CO2 emissions-reducing upgrade to its Airvault cement plant in Nouvelle-Aquitaine. Ciments Calcia first published its plans for the installation of a new 4000t/day production line to replace both existing lines at the Airvault plant in 2021, with commissioning scheduled for mid-2024.
Germany-based ThyssenKrupp secured the order to supply a 1200t/hr double-shaft hammer crusher, a longitudinal blending bed, a 370t/hr Quadropol QMR² 45/23 vertical roller mill, a 10,000t raw materials tangential blending silo, a single-string, five-stage Dopol cyclone preheater with integral calciner for alternative fuels (with the possibility of conversion to oxyfuel), a Polytrack clinker cooler, a solid recovered fuel preparation line and dedusting systems for the project.
Golden Bay Cement uses 80,000t of waste in EcoSure reduced-CO2 cement production to date
17 October 2022New Zealand: Fletcher Building subsidiary Golden Bay Cement has co-processed 80,000t of waste in production of its EcoSure reduced-CO2 general-purpose cement at its Golden Bay, Whangarei, cement plant. The plant has achieved a coal substitution rate of 50%. It has processed various waste streams, including 3 million used tyres. EcoSure cement generates CO2 emissions of 699kg/t of product, 20% less than its imported alternatives, according to Golden Bay Cement. Fletcher building CEO Nick Traber said that this figure is 'simply our starting point.' The company's next target is to achieve a 30% CO2 reduction by 2030.
Traber said "We needed to think outside the box, or rather the cement bag to be more precise. The challenge was around what enhancements we could make to our manufacturing processes at our Golden Bay cement works in order to improve the plant's sustainability. We quickly realised that consuming used tyres and wood waste as alternative fuels was a win-win. When we started with the idea in 2015, we were aiming to replace 15% of coal with end-of-life tyres. Fast forward to 2022, and our rate of coal substitution is now at 50%, which has obviously delivered further reductions in carbon emissions, as well as helping to offset increased coal costs."
FLSmidth secures Euro150m sustainability-linked loan
13 October 2022Denmark: Nordic Investment Bank (NIB) has granted a 150m loan to FLSmidth to support technological developments for the growth of sustainability in the cement and mining sectors. The supplier said that the loan tracks three core sustainability indicators: FLSmidth's ratio of partners with SBTi-certified science-based targets, FLSmidth’s own Scope 1 and 2 CO2 emissions and its products' Scope 3 impacts.
Chief financial officer Roland Andersen said “With our MissionZero pledge, we are fully committed to developing technologies and solutions that will enable the mining and cement industries to move towards zero emissions by 2030. As sustainability is an integral part of everything we do, it is only natural for us to also link our financing to our sustainability ambitions. This is a first step in this direction, and we are very pleased with the long-term commitment provided by NIB."
Science-Based Targets Initiative reviews Heidelberg Materials' emissions reduction targets
12 October 2022Germany: Heidelberg Materials has reaffirmed its 2030 CO2 emissions reduction targets and submitted them to the Science-Based Targets Initiative (SBTi) for review. These include a reduction in Scope 1 emissions per tonne of cementitious material of 47% between 1990 and 2030. The initiative will now ensure that the targets conform to a 1.5°C climate change scenario.
Heidelberg Materials chair Dominik von Achten said “We have been actively supporting SBTi’s efforts to develop a 1.5°C roadmap and impactful criteria for the cement industry. With the industry's most ambitious CO2 reduction targets and a steadily growing portfolio of CCUS projects, we are eager to continue leading the way.”
India: Four UltraTech Cement cement products have received Environmental Product Declaration (EPD) certification. UltraTech Cement's ordinary Portland cement (OPC), Portland pozzolana cement (PPC), Portland slag cement (PSC) and Portland composite cement (PCC) all successfully underwent lifecycle assessment studies in line with EPD requirements.
The Aditya Birla subsidiary said that 70% of its cement sales consist of blended cement. It offers over 70 different GreenPro certified products across its range.
Betolar launches Geoprime concrete products in India
11 October 2022India: Finland-based Betolar has launched its first concrete products manufactured using Geoprime on the Indian market. Geoprime is an additive designed for use in cement-free concrete production with ash and ground granulated blast furnace slag (GGBFS). The new concrete product range consists of precast blocks, paving slabs and tiles, and is currently on display at World of Concrete India in Mumbai, Maharashtra.
Betolar's India managing director Abhishek Bhattacharya said "We are happy to introduce our first products to our customers for the Indian markets. We have now moved from laboratory tests into the production phase, and can show concretely how well this solution works. It is great to hear the feedback from the concrete industry in the region to our sustainable solution. Decarbonisation of the concrete industry is a very current and important topic."
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."
