Launch of the Al2SiBuild project

Neo-Eco is proud to be part of the Al2SiBuild project which began in 2026 and will last for a period of 3 years.

🔍 What is Al2SiBuild?

Al2SiBuild aims to accelerate the development and adoption of geopolymers and alkali-activated materials as sustainable alternatives to Portland cement-based concrete. The goal: to significantly reduce CO₂ emissions and energy consumption in the construction sector by demonstrating the potential of low-carbon concrete made from local and circular resources.

The project is structured around 4 strategic axes:

🌐 Create a cross-border network of expertise

♻️ Identify and promote the use of raw materials available in the FWVL region

🧪 Develop geopolymer/alkaline activated concrete binders and concretes

🏗️ Test their feasibility by creating industrial prototypes of building elements.

🎯 Neo-Eco's role in this project

As a partner in this project, we will contribute our technical and industrial expertise to ensure the successful development of these materials. Our main role will be to:

• The identification and characterization of secondary raw material deposits;

• The development of valorization processes to transform these flows into high-performance eco-materials;

• The creation of local circular economy loops by connecting waste producers and construction companies;

• Technical support for regional businesses to adopt these new construction solutions.

💡 Total project budget: €2.83M including €1.7M from the FEDER fund

📅 Durée : 2026-2028 

🤝 Partenaires : INISMa-CRIBC (BCRC) / CWOBKN, Buildwise, UMONS Recherche, Innovation & Entrepreneuriat, Universiteit Gent, IMT Nord Europe, Centrale Lille, Neo-Eco, and Materia Nova.

The project is also supported by GreenWin, Circular Concrete Center, CD2E, Cluster Cap Construction, Envirobat Grand Est and TEAM 2
