Project description
Mineral wool finds a second life in novel construction products
Mineral wool (stone wool and glass wool) is a non-metallic inorganic fibrous product formed by spinning or drawing molten stone or silica and binding it with resins and oils. Despite being the most widely used form of insulation in the EU, it is generally not recycled at a building's end-of-life. As the construction and demolition sectors move towards a more circular economy, revalorising mineral wool is an important step. The EU-funded WOOL2LOOP project is developing technologies to achieve that, including on-site in situ analyses and smart demolition, improved pre-treatment for smaller particles and novel processing methods, leading to new cement based building material products such as concrete, pavement slabs, building facade elements and acoustic panels.
Objective
Mineral wool within construction and demolition waste (CDW) is considered largely unrecyclable. It is formed at a rate of 2.5 Mt/year and although it is only 0.2 % of total CDW, it requires disproportionally large space due to low density. The WOOL2LOOP project aims to close this material loop by introducing novel technology and value chain to CDW sorting, pretreatment, and processing. The quality of sorted mineral wool is upgraded by comparing and combining the following approaches: pre-demolition audit, robotized demolition and sorting, novel on-site analysis with time-gated Raman spectroscopy, and smart demolition practices. Pre-treatment involves logistical considerations and milling of the mineral wool waste to sufficiently small particles. Processing utilizes alkali-activation (i.e. geopolymerization) technology to convert reactive silica and alumina of the mineral wool into new building material products. Alkali-activation in this context is a completely new approach and it enables to diversely adjust the resulting material properties. Therefore, a broad selection of products were selected for WOOL2LOOP, ranging from relatively low to high value products: hollow core and pavement slabs, facade elements, acoustic panels, dry concrete, floor screed and 3D-printing equipment, for instance. All the required technologies and product manufacturing cases will be demonstrated in large-scale pilots with a wide geographic coverage within the EU. The consortium includes several leading large construction material enterprises and innovative SMEs to cover the whole value chain. Safety, health, environmental, and economic aspects are considered throughout the project. According to the preliminary calculations, there is a strong business potential in the WOOL2LOOP concept. Finally, the constantly increasing landfilling costs (approx. 250 M€ for mineral wool in the EU) create a clear economic driver for the project.
