Indonesia: Cemindo Gemilang says that its subsidiary Merah Putih Beton has begun injecting CO2 captured using direct air capture (DAC) into its ready-mix and precast concrete products. The producer said that the method enables it to produce concrete using 18% less cement. The Koran Jakarta newspaper has reported that Cemindo Gemilang obtained the DAC technology under licence from its Canada-based developer. It deployed it following six months of trials in late 2023 – early 2024.
Cemindo Gemilang’s commercial director, Surindro Kalbu Adi, said “In the future, we will implement a lot of new technologies. The goal is that our Red and White brand products will be better and the quality of buildings will be even better.”
Saint-Gobain Construction Chemicals’ CHRYSO Quad Lab wins Tarmac 2023 Innovation Challenge
03 June 2024UK: Saint-Gobain Construction Chemicals has won Tarmac's 2023 Innovation Challenge with its CHRYSO Quad Lab, a digital admixture optimisation tool. CHRYSO Quad Lab analyses sand prior to mixing, aiding in the reduction of the cement content of concrete.
Tarmac’s procurement manager, capex and sustainability, Mark Lewis said "Circularity within the materials industry is crucial to reaching net zero and reducing our impact on the environment. To achieve our sustainability ambitions, we know that collaborating with our suppliers is key to developing innovative new ideas and solutions.”
Australia: Local authorities in Isaac, Queensland, have received an application for the planned US$664m Lotus Creek wind farm, including the construction of three temporary ready-mix concrete batching plants to supply the project. The plants will supply 55,000m³ of concrete for the footings of 46 turbine towers. Each one will operate successively as construction progresses over a period of two years. The Lotus Creek wind farm originally secured planning permission in late 2022.
Colombia: Cemex Colombia has announced the launch of its 40% reduced CO2 Vertua mortar.
The company said "Vertua aims to enable builders to adapt the sustainable features of their projects through its five specific and measurable attributes: lower carbon emissions, energy efficiency, water conservation, recycled materials and design optimisation."
Global: The Global Cement and Concrete Association (GCCA) has announced new collaborations between global cement manufacturers and technology start-ups, focusing on the development of low carbon concrete. Four start-ups—EnviCore in Canada, Queens Carbon and Chement, both in the US and NeoCrete in New Zealand—were part of the 2023 GCCA Innovandi Open Challenge and have now partnered with cement manufacturers. These partnerships aim to reduce the carbon footprint of concrete.
The startups will receive access to industry plants, labs and networks to fast-track their technologies. They will also demonstrate their progress on 6th June 2024 in Bangkok, Thailand, during the GCCA's CEO and Leaders Conference. The association continues its efforts under the 2050 Net Zero Concrete Roadmap, with 29 new start-ups shortlisted this year to work on carbon capture, utilisation and storage (CCUS) technology.
US: St Marys Cement won three national awards at the Slag Cement in Sustainable Concrete Awards 2023. The producer won the awards for supplying its slag cement for the construction of Wixom Assembly Park in Wixom, Michigan; of 333 North Water in Milwaukee, Wisconsin, and of Excellerate Manufacturing in Appleton, Wisconsin.
UK: Heidelberg Materials UK has opened a new circular materials hub at its Appleford depot in Oxfordshire. The site will recycle construction waste for use in low-CO2 building materials. The move advances the company’s strategy to conserve natural materials and support the circular economy.
Recycling managing director James Whitelaw said “Recycling, reusing and reducing the use of primary raw materials is crucial to reaching net zero. Our network of recycling hubs will allow us to provide the most sustainable products to our customers through circularity and innovation to enable building more with less.”
Spain: Bio-Ecomatter, a company based in Extremadura, has launched a new sustainable mortar product without cement or sand, using agro-industrial waste as raw material. This product was developed by founders Carmen Tristancho and Lorena Rodríguez, along with Juanjo Tejado and Marisa Carmona from the Institute of Ornamental Rocks and Building Materials.
Bio-Ecomatter's product composition remains confidential. Beyond reducing reliance on traditional materials like cement, it promotes environmental sustainability by utilising agro-industrial waste. Carmen Tristancho, who heads the innovation department at an environmental engineering firm in Badajoz and co-created the product, revealed that the mortar includes hydraulic lime and agro-industrial waste. The mortar reportedly has a 40% higher performance than standard mortar and is half the density. It has the same texture and workability as conventional mortar, with a formula that minimises carbon emissions and lessens reliance on non-renewable raw materials.
The project, while not aiming to replace traditional mortar, introduces alternative sustainable construction methods. Bio-Ecomatter's product won the sustainable construction award from Metabuilding, an EU-funded project supporting SMEs in the construction sector. Tristancho reveals they are also working on projects using recycled plastic moulds filled with their Bio-Ecomatter mortar.
Tristancho said "We are women in a field very centred on cement and sand, so introducing a new material in construction can be met with scepticism."
World: Investment firm Insight Partners has forecast a composite annual growth rate (CAGR) of 3.3% in the global green cement and concrete market between 2023 and 2030. This will result in a total value of US$990m in 2030, compared to US$806m in 2023. Regionally, the firm expects the sharpest growth in South and Central America, with a CAGR of 10% to US$7.9m in 2030. North America is expected to grow at a rate of 5.4% annually, to US$190m, followed by Europe, at 4.5% to US$226m, Middle East and Africa, at 2.9% to US$13m, and Asia-Pacific, at 1.4% to US$553m. In 2023, Asia-Pacific commanded a 61% share of the global market. Europe’s share was 20% and that of North America was 16%.
US: Terra CO2 has begun full-scale trial production of concrete without cement using its novel supplementary cementitious material, Opus Zero. The SCM consists of ground, heated glass spheres made from silicate rock.
Chief scientific officer DJ Lake said “Opus Zero represents a pivotal moment in our journey towards sustainable cement and concrete. Of the very few non-carbon-capture solutions to decarbonising cement, with none proven at scale, Opus Zero stands above the rest for being inherently cost-efficient, practical and scalable for the industry. Today, Opus Zero represents a zero-clinker cement that can be produced with abundant feedstock around the world, does not require opening new mines to scale, and aims to seamlessly fold into the current industry landscape.”
