Informative research from the Norwegian University of Science and Technology (NTNU) and SINTEF Energy Research assessing 15 #decarbonization options for the #cement industry including changes in fuel use, clinker substitution, and carbon capture and storage (#CCS). Conclusion: "The combination of decarbonization options based on CCS and alternative fuels (CombOxyCCS+RDF, CombOxyCCS+Bio and CombOxyCCS+H2) is projected to achieve near-to-full decarbonization and a net-zero European cement industry (from 96% to 108% emissions reduction). In particular, a full deployment of the bio-based combination delivers negative emissions." #decarbonisation #cementindustry #carboncapture #ccus #concrete Otávio Cavalett Marcos Watanabe Mari Voldsund Simon Roussanaly

Material Evolution has developed a manufacturing process to produce low carbon cement from industrial waste. Concrete is the second most used material in the world after water, and cement equates to about 8 per cent of global CO2 emissions

The companies that have agreed to work towards accelerating the rate at which the cement industry is decarbonised, have also agreed to focus on carbon capture as their main technology drive. The decarbonisation of this industry is so important because of the necessary process of heating limestone which produces unavoidable carbon emissions. The process of creating cement requires the ability to perform the task of heating limestone, which means the manufacturing process of cement, a necessary material, is guaranteed to emit carbon dioxide. This is why carbon capture is a very important technology when it comes to bringing the cement industry to a point where it is able to achieve net zero, through reducing as much of the unavoidable emissions as possible. The article below highlights how the global drive towards a carbon neutral future and the improvements which lots of companies are looking to make, does not mean that processes which society relies on have to be stopped because it produces carbon. Projects like these effectively prove that finding ways around these solutions to make necessary processes better for the environment is an option, one which many companies are looking into.

New carbon capture project 🌱 In 2024, environmental considerations are top of mind across a range of industries. As a company, we’ve helped many of our clients develop durable solutions over the years, ranging from bio-ethanol installations and green ammonia tank parks to biomass conversion and dedusting installations. But did you know you can also count on Geldof for all your carbon capture needs? 💡 According to a study by the IPCC, carbon capture technology could play a significant role in reducing greenhouse gas emissions over the course of the current century. Many vital industries are struggling to find viable alternatives to fossil fuels, but they can still meet their short-term emissions targets by sequestering and storing their excess CO2. There are even innovative efforts being made to convert the stored carbon dioxide into useful products like concrete, certain polymers or fuel. 🎯 One such carbon capture project – the largest project on this scale in the Netherlands - was recently launched by Yara Sluiskil. We are honored to announce that they are entrusting Geldof with the design and production of all 7 horizontal storage tanks, each with a volume of 2.250 m³ and a total weight of 382,5 tons/piece. The storage tanks will be prefabricated in 3 parts in our workshop (BE) and shipped to our partner Mammoet Westdorpe (NL). There, the separate parts will be assembled, pressure tested, blasted and insulated, before being transported by road to their permanent location. 💚 Thanks again to Yara Sluiskil for the confidence they’ve given us. 🔔 Be sure to like and subscribe for future project updates – and who knows, maybe we’ll also have the green solution for you? #greensolutions #storagetanks #sustainable

Greener World @zeroemissioncement #greenworld #zeroemissioncement Creating a green world with zero-emission cement is an ambitious yet essential goal for mitigating climate change and promoting sustainable development. Achieving this involves several key strategies: 1. **Innovative Technologies**: Developing and deploying new technologies that reduce or eliminate CO2 emissions during the cement production process. This includes carbon capture, utilization, and storage (CCUS) technologies that capture CO2 emissions from cement plants and either store them underground or repurpose them for other industrial uses. 2. **Alternative Materials**: Utilizing alternative raw materials that produce less CO2. For example, using industrial by-products like fly ash, slag, or silica fume in cement production can reduce the carbon footprint. 3. **Energy Efficiency**: Improving energy efficiency in cement manufacturing processes. This can be achieved through modernizing equipment, optimizing operations, and adopting energy-efficient practices. 4. **Renewable Energy**: Powering cement plants with renewable energy sources such as wind, solar, or biomass instead of fossil fuels. This transition can significantly reduce the carbon emissions associated with cement production. 5. **Carbon-Neutral Fuels**: Using alternative fuels derived from waste materials, such as municipal solid waste, tires, or agricultural residues, which can help to reduce greenhouse gas emissions. 6. **Product Innovation**: Developing new types of cement that have a lower carbon footprint. For instance, geopolymers or other novel cementitious materials that require less energy to produce and emit less CO2. 7. **Circular Economy**: Embracing circular economy principles by recycling and reusing materials. For example, reclaiming and recycling concrete from demolished structures can reduce the demand for new cement. 8. **Policy and Regulation**: Supporting and advocating for policies and regulations that promote the adoption of low-carbon technologies and practices in the cement industry. 9. **Industry Collaboration**: Collaborating with other stakeholders, including governments, non-profits, academia, and other industries, to share knowledge, resources, and innovations that drive the transition towards zero-emission cement. By implementing these strategies, the cement industry can significantly reduce its environmental impact and contribute to a more sustainable and green world.

Check out our last work on the use of recycled polyvinyl butyral (PVB) for the preparation of separators for Li-ion batteries! 🔋 PVB is a random ter-polymer normally used as interlayer into laminated safety glasses for the automotive industry and for architecture. At the moment, most of the post-consume PVB is incinerated or landfilled and just 9% is repurposed. Indeed, the recycling process of this polymer presents several difficulties, like glass residues, impurities and lack of the original optical properties. The European SUNRISE Project aims to find new smart ways to separate the fraction which could be still used in the glass sector from the fraction that cannot be utilised anymore, repurposing it in other innovative sectors. In this perspective, the battery field could be a brilliant option 🔋💡and in this article we explore its use as separator. Thanks to my colleagues and to the project partners for the nice collaboration!

Staying power: wear protection solutions in Energy from Waste plants: Changing attitudes and regulations are making efficient, long-lasting operation more important than ever for Energy from Waste plants (EfW). Martin Trenk, Head engineer for Boiler coatings and EfW applications at Castolin Eutectic, explains. To fulfil the role of baseload in the power generation mix, thermal power plants must prioritise consistent power output. Maintaining consistent operation and output is a particular challenge for EfW plants, whose fuel – municipal waste – does not necessarily always yield the same amount of energy per tonne. The last thing an EfW plant operator wants, while closely monitoring and finely calibrating the boiler temperature and turbine speed, is an unplanned stoppage. Yet many EfW plants do contend with frequent stoppages, both planned and unplanned, to replace worn parts or to mitigate emissions. With the European Union tightening its rules around burning municipal waste, EfW operators need to prove their plants can be efficient and play their assigned role in their nations’ power systems. It’s a question of industrial sustainability. https://lnkd.in/eVwjTFma #news #pr #magazine #advertising #b2b #bannerad #magazine #newsletter #emailcampaigns #engineering #automation #manufacturing
