Allwood Cement #production causes 7.5% of global #anthropogenic CO2 #emissions, arising from #limestone decarbonation and #fossilfuel #combustion. Current #decarbonation strategies include substituting #Portland clinker with supplementary materials, but these mainly arise in emitting #processes, developing alternative #binders but none yet promises scale, or adopting carbon capture and storage (#CCS) that still releases some emissions. However, used #cement is potentially an abundant, decarbonated #feedstock. Here the authors show that recovered cement paste can be reclinkered if used as a partial #substitute for the #lime – #dolomite flux used in #steel #recycling nowadays. The resulting #slag can meet existing #specifications for Portland #clinker and can be blended effectively with #calcinedclay and #limestone. The process is sensitive to the #silica content of the recovered #cementpaste, and silica and #alumina that may come from the #scrap, but this can be adjusted easily. They show that the proposed #process may be economically competitive, and if powered by emissions-free #electricity, can lead to zero emissions cement while also reducing the emissions of #steelrecycling by reducing #limeflux requirements. The global supply of #scrapsteel for #recycling may treble by 2050, and it is likely that more #slag can be made per unit of steel recycled. With #materialefficiency in #construction future global #cement requirements could be met by this route. The article link is here: https://lnkd.in/dx6RDay67

#Plastic was one of the great innovations of the 20th century #Liquid wood could soon supplant the chemical in terms of everyday usefulness. #Liquid wood is derived from wood pulp-based lignin and can be mixed with a number of other materials to create a strong, non-toxic alternative to petroleum-based plastics. #Preparation of Liquid Wood from Paper By-Product. #Liquid wood is a biopolymer thermoplastic composite that is manufactured from substances derived from wood (lignin). #However, the material is still little known as a valid substituent for thermoplastic polymers with high environmental impact. #The cellulose industry separates wood into its three main components – lignin, cellulose, and hemicellulose. #The lignin is not needed in papermaking #However, People mix lignin with fine natural fibers made of wood, hemp or flax and natural additives such as wax. #From this, they produce plastic granulate that can be melted and injection-moulded.

A concrete paper to clear all doubts! 🪨 A good read for all the carbon removal nerds out there. Especially for anyone involved in CDR Standards, CDR buyers, LCA experts and National Standard Organisations. We need a strong alignment to scale up this technology to the next level! Reach out to ecoLocked or the European Biochar Industry Consortium (EBI)(or to me) if you have questions, remarks, feedback or want to learn more!

Food for thought in this article by Hannah Ritchie for Sustainability by Numbers. In it, she discusses some of the international innovations working to decarbonise cement. Ritchie focuses on 3 innovation themes: 1. Use less cement 2. Capture the CO2 3. Find a new process for making cement Would you agree with Ritchie or do things differently? https://lnkd.in/gPeSs8Tm #racetonetzero #netzerotransition #buildingprogress #constructionprogress #concrete #cement

This aluminium scrapS may come from a variety of sources, including old aluminium products, industrial scrapS, construction and demolition materials, etc. Recycled aluminium materials have a lower production cost and environmental impact while maintaining the original aluminium properties.

Vinyl siding continues to lead the way in sustainability with its zero-waste manufacturing, resource efficiency, and long product life cycle. It also plays a crucial role in reducing carbon emissions and water use. But did you know vinyl siding is also termite-resistant, as recognized by Polymeric Exterior Products Association (PEPA)? Another reason why vinyl siding is a top choice for eco-friendly building materials. https://lnkd.in/guXaCPgV

Slag: A Greener Alternative to Base Scrap 🌿 In the steel production industry, managing byproducts effectively is crucial for sustainability. Slag offers a more eco-friendly alternative to base scrap, providing significant environmental benefits when processed and utilized correctly. Why Slag is More Eco-Friendly than Base Scrap ❓ 🔺 Resource Efficiency: Slag recycling and reuse minimize the need for virgin raw materials, conserving natural resources and reducing environmental degradation from mining activities. 🔺 Lower Carbon Footprint: Processing slag requires less energy compared to base scrap, resulting in lower greenhouse gas emissions. This contributes to a reduced carbon footprint for steel production. 🔺 Waste Reduction: Utilizing slag in construction and other industries helps divert it from landfills, reducing waste and its associated environmental impacts. Slag can be used as aggregate in concrete, road construction, and other applications, promoting a circular economy. 🔺 Reduced Environmental Contamination: Slag can immobilize contaminants and heavy metals, preventing them from leaching into the environment. This makes slag disposal and storage less harmful compared to untreated base scrap. Sustainable Practices in Slag Management ✅ 🔺 Advanced Recycling Technologies: Implementing cutting-edge recycling technologies ensures that slag is processed efficiently, maximizing its reuse potential and minimizing environmental harm. 🔺 Eco-Friendly Applications: Encouraging the use of slag in eco-friendly applications, such as cement production, can further enhance its environmental benefits. Slag-based cement has lower carbon emissions compared to traditional Portland cement. 🔺 Monitoring and Regulation: Strict monitoring and regulation of slag processing can prevent environmental contamination and ensure safe handling practices. This includes proper management of leachates and emissions. Let's embrace slag as a key component in our journey towards a more sustainable and eco-friendly steel industry! 🏭 🌳 #metallurgy #slagprocessing #environmentalimpact #sustainability #steelproduction #greensteel #ecofriendly #smartscrap #slag #slagmanagement

♻ New recycled cement miracle discovery made by Cambridge University! ☁ Concrete is the second-most-used material on the planet, after water, and is responsible for approximately 7.5% of total anthropogenic CO2 emissions. ⚡ Researchers at the University of Cambridge have developed a process for recycling cement which could allow the production of low-emission concrete at scale. The method, which the scientists describe as “a miracle”, uses the electrically-powered arc furnaces used for steel recycling to simultaneously recycle cement. The Cambridge researchers found that used cement is an effective substitute for lime flux, which is used in steel recycling to remove impurities and normally ends up as a waste product known as slag. But by replacing lime with used cement, the end product is recycled cement that can be used to make new concrete. The researchers say the process, according to the journal Nature, does not add any significant costs to concrete or steel production and significantly reduces emissions from both concrete and steel, due to the reduced need for lime flux. 👉 What are your thoughts on this?
