🌍Did you know? Although fibre cement can be energy-intensive to manufacture, its minimal weight contributes to the overall low energy requirements for the building. This makes it one of the most environmentally friendly facade cladding materials, with a lifespan of over 50 years, low maintenance requirements, and 100% recyclability after.   Reducing the carbon footprint of fibre cement facades can be significantly enhanced by focusing on recyclability and the creative use of residual materials. Advances in recycling technologies increasingly enable the recycling of fibre cement. By breaking down used fibre cement into its raw components, these materials can be reused in new production, reducing the need for new raw materials and the CO2 emissions associated with extraction and processing.   Using recycled materials in fibre cement production minimizes waste and reduces the environmental impact of disposal. Efficient collection and processing systems for spent fibre cement products can further streamline this recycling process. Additionally, promoting the use of recycled content in new fibre cement products supports a circular economy.   Overall, improving the recyclability of fibre cement facades will contribute to reducing their carbon footprint by decreasing raw material demand, energy consumption, and waste sent to landfill, resulting in more sustainable building practices. #fdb #dijkstra #sustanibility #recycling #carbonfootprint #fibrecement #facade #facadedesign #facadeengineering

October is Circular Economy Month! We’re incredibly excited by the circular qualities of cement and concrete. Whether it's recycled aggregates being used underneath a road, or a concrete building being re-used, concrete plays an essential and increasing role in the circular economy. #circulareconomy

You might not think it, but the concrete industry is one of the largest contributors to CO2 pollution 🏙️ Cement production alone generates around 2.5 billion tonnes of carbon dioxide (CO2) per year—about 8% of the global total. So - it's super important that we find a suitable alternative to concrete to protect the future of our planet. Our Smartawood™ recycled plastic lumber is a great sustainable alternative to using concrete, timber, metal, and virgin plastics. Are you considering durable alternatives to concrete, timber and metal that not only require zero maintenance, but are carbon negative? Find out more about the benefits of using Smartawood™️ on our website. #Lumber #RecycledPlastic #SustainableMaterials #Concrete #Construction

🏢✳️A Review on the Recycled Utilization of Solid Wastes in Building Materials: The substantial generation of solid wastes globally from sources including households, industries, commercial activities, and construction demolitions raises significant environmental cpncerns. Utilization of these wastes in making building construction materials can reduce the magnitude of the associated problems. When these waste products are used in place of other conventional materials, natural resources, and energy are preserved, and expensive and/or potentially harmful waste disposal is avoided. Recycling which is regarded as the third most preferred waste disposal option, with its numerous environmental benefits, stands as a viable option to offset the environmental impact associated with the construction industry. This review the results of laboratory tests and important research findings, and the potential of using these wastes in building construction materials with a focus on sustainable development. Research gaps, which includes; the need to develop standard mix design for solid waste-based building materials; the need to develop energy efficient method of processing solid waste use in concrete; the need to study the actual behavior or performance of such building materials in practical application and the limited real life application of such building materials have also been identified. Research is being proposed to develop an environmentally friendly, lightweight building block from recycled waste paper, without the use of cement, and with properties suitable for use as a walling unit.

Over 3 billion tonnes of construction and demolition waste are produced globally every year, and how we deal with it is changing. As part of our signature GREENKEY SOLUTIONS, S/CRETE technology makes possible concrete recycling on an industrial scale. With its unique selective grinding technology, we can efficiently separate and reuse the components of waste concrete to reduce energy dependency and water consumption while minimizing carbon emissions. This patented process brings a new opportunity to achieve a truly circular economy in the cement industry. Our goal for selective concrete recycling is outlined in detail in this technical article, available for download here: 🔗 https://lnkd.in/dfTmyvv4 #concreterecycling #sustainableconstruction #circularity #cementinnovation Article by Dr. Martin Reformat & André Trümer published in Global Cement Magazine, September 2024 issue.

Our mission: closing the loop! Cement and concrete are high-quality and much needed building materials that require a lot of energy to produce. This makes it all the more important to utilise their full potential and strengthen circularity along the entire value chain. As a next step towards our circularity and carbon reduction targets, we have now commissioned an innovative recycling plant for selective separation at the Heidelberg Materials production site near Katowice, Poland: The first-of-its-kind facility features a proprietary crushing mechanism that enables sophisticated separation and sorting capabilities to fully recycle demolition concrete and substitute virgin materials in concrete production. By also recovering recycled concrete paste (RCP), our patented ReConcrete process combines circularity with decarbonisation. RCP can then be used as an alternative raw material in clinker production or as an alternative cementitious material. In addition, it can absorb and permanently bind CO₂.

This could solve one of the biggest issues in climate: Recycling old cement. I know it doesn't sound so sexy, but: 1. Concrete (from cement) generates 8% of global CO2 - that's more than any nation besides US and China 2. Cement making is super energy-intense - Impossible to recycle, virgin, with fossil fuel use 3. Now scientists have found a way to solve this: - Using processes from steel recycling, r-cement is born This does not add any significant costs to concrete or steel production and heavily cuts emissions from both concrete and steel. That's what we need: Innovation at a massive scale. Profitable. Using waste as a resource. Big thumbs up for this one! 👍 Hit follow for more circular news ♻️ Repost to celebrate this win #circulareconomy #climatechange #construction

Concrete is fundamental to our modern world, but its production is a significant source of CO2 emissions. The reuse of old cement could be a ‘game changer’ for reducing the carbon footprint and cost of concrete used in the construction industry. Let's champion sustainable innovation and build a better future, one concrete step at a time. #Sustainability #LowCarbonConcrete #GreenBuilding #ClimateAction #CircularEconomy
