We are happy to share our latest book chapter titled "Properties of concrete containing polyethylene terephthalate and artificial lightweight aggregates: a case study" in the book "Reuse of Plastic Waste in Eco-efficient Concrete" https://lnkd.in/dGGkf9eM Artificial lightweight aggregates (ALWAs) produced by using waste materials are a suitable alternative to natural aggregates. This work proposes a multicriteria decision model to select the ALWAs through an experimental process. The integrated mechanical (crushing test), environmental (life cycle assessment), and economic (life cycle costing) analysis was carried out for ALWAs to choose the most suitable aggregate. These ALWAs were used to create light concrete (LC), and a portion of the ALWAs was replaced with recycled polyethylene terephthalate (PET). Thank you to all our co-authors Jehangeer Raza, Narinder Singh, Ph.D., Ilenia Farina, Ph.D.

#SodiumLignosulphonate SLS For construction chemical,concrete admixture Water Reducing Agent: It is widely used as a water reducing agent in concrete admixtures. It enhances the fluidity of concrete without increasing water content, improving workability and reducing water requirements. Binder: Sodium lignosulfonate acts as a binder in various applications such as pelletizing, where it helps in binding fine particles together to form pellets. This property is particularly useful in industries like agriculture and pharmaceuticals. Dispersant: It serves as an effective dispersant in industries such as ceramics, where it disperses solid particles to prevent agglomeration and improve the consistency of slurries and suspensions. Adhesion: In addition to binding, it also provides adhesive properties, making it useful in applications where adhesion strength is required, such as in the production of animal feed pellets. Environmentally Friendly: Sodium lignosulfonate is derived from natural lignin, which is a byproduct of the paper industry. It is biodegradable and poses minimal environmental impact compared to synthetic alternatives. Cost-effective: It is relatively inexpensive compared to other additives with similar functionalities, making it economically viable for various industrial applications.

🌍♻️ Did you know that paper sacks can support the European cement industry in going #circular? Thanks to their performance and high #efficiency, paper sacks are widely used for #cement and other building materials. Three billion paper sacks were placed on the European market in 2023. However, few of them are currently collected and recycled – a great potential for change. In our recent article in World Cement, we explain why and how #recycling paper sacks can contribute to the European cement #industry’s path towards a circular #economy and its net-zero target. 💪 #sackkraftpaper #kraftpaper

A good use of plastic waste materials is by using in building materials!
PLASTIC Recycling building material ------------------------ Plastic fine particulates along with sand, aggregate and mineral admixture has been explored to develop building materials by adopting an Inovative Rock forming process. ■ The process is cement free Shareing below a casting of concrete mix specimen incorporated with Plastic fines which after atmospheric and water curing attains about 20Mpa crushing strength on 28days. ■The Plastic particulates are embedded in rock forming silicate matrix. However more experimental work is required to optimize the process for making high strength road application concrete and also effect of plastic particulates in the reaction process and also the product durability.

Screening Handling - disposing of the solids removed by the inlet screening. Screening is the initial step in wastewater treatment, designed to remove large, solid objects that could damage equipment or hinder the overall process. Common solids removed through screening include: * Large debris: Sticks, stones, branches, and other natural materials. * Household items: Rags, diapers, wipes, sanitary products, and plastic items. * Industrial waste: Metal scraps, food waste, and other industrial byproducts. * Organic matter: Leaves, grass clippings, and other plant matter. These materials are typically captured by metal bars or screens with varying spacing depending on the desired level of filtration. SAVECO Environmental Limited SAVECO® WAMGROUP®

Let's not sugarcoat it… 🙅 Living in the past is not going to inspire innovation or help us drive our industry forward! In years gone by, PU concrete with antimicrobial additives has been touted as the industry gold standard for food & beverage applications, marketing health benefits. Research by International Living Future Institute and the development of the Living Building Challenge (LBC) Red List has overturned this old-hat thinking! Beyond antimicrobials marketed with health benefits, phthalates and VOCs make the list of harmful substances. What is the Red List & what is its purpose? 🤔 🔍 Identifies materials that pose serious health and environmental risks 🚫 Advocates for the complete phase-out of harmful substances 🍃 Serves as a crucial tool in aiming for sustainable materials 🔁 Evolves with each new version of the LBC Standard Learn more about the Red List, its future impact on manufacturing in the construction industry, and how Vebro Polymers' new vebrocrete polyurethane concrete range complies here: https://lnkd.in/dbMmg-5H #innovation #resinflooring #foodflooring #puconcrete Robert Gray Rebekah Jones Mark Verinder FCA Jon Morris Claire Schofield Mark Ingram Linsey Caroline

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!
Our very own Riccardo Ambrosini has co-developed a new European Biochar Industry Consortium (EBI) position paper on the permanence of biochar storage in concrete. This is a topic that is absolutely crucial to understand in detail as we must ensure the longevity of carbon removal. 🪨 𝐇𝐢𝐠𝐡𝐥𝐢𝐠𝐡𝐭𝐬: ◾ A significant part of the carbon in biochars produced over 550°C is structurally equivalent to inertinite, a highly stable part of the earth’s crust. ◾In concrete, inertinite biochar becomes an inseparable part of the cement matrix. The only risk of reversal, i.e., a re-release of emissions, emerges if it is subjected to extremely high temperatures. Note that heat-based clinker recycling is in discussion but is only one of many methods being researched to obtain clinker from used concrete. ◾Most concrete material is recovered at the end-of-life, either for use as recycled aggregates or downcycled for use as a filler, such as in roads ◾None of the established recycling methods for concrete reach very high temperatures, meaning that the carbon storage will endure 𝐅𝐮𝐥𝐥 𝐩𝐚𝐩𝐞𝐫 𝐥𝐢𝐧𝐤 𝐢𝐧 𝐜𝐨𝐦𝐦𝐞𝐧𝐭𝐬 ⬇️ Matt Mallory, Olivia Thierley, Julian Cortes, Anna J.

Siniat’s metal framing products are a good example of “#circular products” and the closed loop usage model. End-of-life refers to the end of a product’s life cycle. In the case of building products, this stage is often the #deconstruction of the building it was installed in. According to the 2018 National Waste Report, we know that an average of 90% of the metal products produced in Australia are recycled at end-of-life by factories that produce new steel that then goes back into the loop. Siniat uses BlueScope steel with 25% #recycled content to make our products. We have also made significant progress in the reduction of the scrap we generate on site, with 50% less waste compared to 2016. All on-site waste we generate in the manufacture of our metal products is recycled. #Circularity is one of the pillars of the Etex Road to Sustainability 2030, and an important part of our sustainability strategy. To find out more the life cycle of Sinat products and their environmental impact, download our Environmental Product Declarations (EPDs) for plasterboard and metal framing from our website https://lnkd.in/gTFZYcb9.
