What if the very product that drives 7% of all the Earth's hashtag #GHG emissions also held the key to reducing human impact on the climate? The cement industry (and thus, concrete) is responsible for a huge slice of global CO2 emissions because of the way it is made today which not only requires significant heat input, but also releases embedded carbon from the raw materials. As this McKinsey & Company article discusses, industry is working on solutions intended to reduce, neutralise and even embed carbon emissions through a selection of novel approaches. Some hashtag #startups have tackled the problem from the perspective of capturing and storing emissions through hashtag #CCUS, whereas another approach is through the chemical enhancement of concrete mixes through hashtag #admixtures which reduce the need for cement. The top of the pyramid, in our opinion, is the use of Supplementary Cementitious Materials hashtag #SCM which fundamentally changes the chemistry of the process to reduce emissions and, ultimately, to embed more Carbon than is emitted. The most exciting of these business models provides the opportunity to supply concretes that use waste products and to embed, permanently, airborne CO2 through the curing process. This provides developers with a potential new income stream from Carbon offsetting credits alongside meeting development targets and reducing the human burden on the planet. What's the downside? Time... 2023/4 has shown us that changes in our climate can happen even quicker than feared. So here it is, an industry that can employ millions of people, create sustainable buildings and infrastructure and permanently embed CO2. Jump on board the hashtag #greenconcrete industry now as it teeters on the edge of exponential growth and watch this space to see how AIMS INTERNATIONAL UK hopes to help propel the most promising growth stories in the sector to greatness. Who knew that hashtag #concrete could be so exciting? https://lnkd.in/eh3kwmqj

This is a sector that's about to get a whole lot more exciting, alongside #climatetech more generally, we can see specific technologies like this reaching critical mass in terms of investment to commercialise and make them the new normal.

UP FOR A PIONEERING CHALLENGE 🪨💡💭👷👷♀️🏆: A pioneering international programme has launched, bringing together tech start-ups and leading cement manufacturers in the pursuit of net zero. Innovandi Open Challenge 2024 is run by the GCCA – Global Cement and Concrete Association (GCCA), the industry's leading international body, which is focused on helping the global cement industry reduce its emissions and ultimately achieve net zero concrete.    Applications are being encouraged from start-ups from around the world interested in working on developing carbon capture use and storage for low-carbon cement and concrete. Innovative technologies are sought, which include process integrated and end-of-pipe CO2 capture and use, and help prevent carbon from being emitted into the atmosphere.🌍♻️💚Thomas Guillot Claude Lorea Simon Thomson Andrew Minson GCCA India - Global Cement and Concrete Association, India #cement #concrete #innovation #technologies #sustainability #netzero

Cement is a critical ingredient for concrete – the most used material in the world behind water. Concrete is difficult to replace and cement production is emissions heavy, leaving the industry and its investors exposed to transition risks. Robeco's proprietary decarbonization model looks as listed cement company's strategies, quantifies their climate risks and provides an early signal for cement's transition-ready leaders.

The utility of cement as a construction material is undoubted, forming the foundation of our buildings and cities. However, producing cement comes at a significant cost to the environment. The Wall Street Journal highlights some of the decarbonization technologies available to the cement industry including our AI-powered software solution, Delta Zero. "Small improvements can add up to a sizable emission effect. “A 2% of fuel saving translates to tens of thousands of tons of carbon per plant being saved,”Aidan O'Sullivan" Yusuf Khan #cementindustry #decarbonization #ai https://lnkd.in/e6A7_uDW

Did you know that 7% of all GHG emissions comes from cement production? Lets have a look at how the cement industry is leveraging innovative technologies such as AI-driven efficiency improvements, solar-powered cement production, and alternative materials to reduce its carbon footprint while meeting the demands of construction. Lets have a look at the prominent industry movers and shakers: 1) Carbon Re, a startup, is using AI and machine learning to optimize fuel usage in cement production, reducing waste and emissions. 2) CEMEX, a major cement producer, is collaborating with Synhelion to produce clinker using solar energy, eliminating fossil fuel combustion. 3) Synhelion aims to add carbon capture technology to absorb CO2 emissions released during the cement production process. 4) Heidelberg Materials is building a carbon capture and storage facility to capture emissions from cement production, partnering with Shell, Total, and 5) Partanna, a startup, is creating an alternative cement that avoids traditional clinker-making, using brine and waste products from steel production. This process also absorbs CO2. 6) Partanna's cement is as strong as traditional cement and becomes stronger when exposed to seawater, making it suitable for sea walls and flood defenses.

Partanna features in the The Wall Street Journal's deep dive on reducing carbon emissions in cement production with Yusuf Khan "Delaware-based Partanna, avoids using portland cement as a binder and instead relies on natural chemistries. Co-founded in 2020 by former National Basketball Association player Rick Fox, the company uses a combination of brine from desalination plants and waste products from steel production called slag to create a new form of cement."

Huge improvement: 40% less cement to make a concrete product with the same, or even better features 🔥 Today Carbonaide is happy to launch the first commercially available products with Rakennusbetoni- ja Elementti Oy that utilize our precision curing technology, originating from VTT's research. With this kind of results, the launch is even more fun! The first products work as an excellent example of how that precious, captured #CO2 is put to its best use. The majority of its decarbonization effects come in fact from the utilization of CO2 and carbon removals are just a happy extra feature. But vital - and permanent. This describes our technology quite nicely: we are not just pushing new ingredients to the concrete mix but improving efficiency. In other words: Making more with less. Check more info on our press release. Now let's decarbonize the rest 💎 https://lnkd.in/daPV_R68

Cement is a critical ingredient for concrete – the most used material in the world behind water.

"To achieve the goal of a climate-neutral Switzerland by 2050, strategies and processes with a negative CO2 balance are necessary. These so-called negative emission technologies (NET) are intended to counterbalance the remaining "hard-to-avoid" emissions in 2050 and should help ensure that we eventually achieve net zero. As one of the main emitters, the construction sector has a particular obligation. About 8% of global greenhouse gas emissions are caused by cement production. At the same time, initial efforts are emerging to use the construction sector, with its massive consumption of resources, as a possible carbon sink. What sounds paradoxical will succeed if we start "building with CO2"—or rather, using carbon to produce building materials and thus removing it from the atmosphere in the long term. For such visions to become reality, a great deal of research is needed—such as is currently being done at Empa's Concrete & Asphalt lab. A team led by Pietro Lura is developing a process for integrating biochar into concrete." #biochar #concreteproduction #co2
