Descripción del proyecto
La lana mineral obtiene una segunda vida en nuevos productos de construcción
La lana mineral (lana de roca y lana de vidrio) es un producto fibroso, inorgánico y no metálico compuesto por sílice o piedra fundida esbozada o hilada que está unido con resinas y aceites. A pesar de ser la forma de aislamiento más utilizada en la Unión Europea, generalmente no se recicla al final de la vida útil de un edificio. A medida que los sectores de la construcción y la demolición avanzan hacia una economía circular, la revalorización del mineral de lana representa un paso importante. El proyecto WOOL2LOOP, financiado con fondos europeos, desarrolla tecnologías para lograrlo, como demoliciones inteligentes y análisis «in situ» y presenciales, tratamientos previos mejorados para partículas más pequeñas y nuevos métodos de procesamiento, lo cual lleva a nuevos productos de cemento basados en materiales de construcción, como hormigón, bloques de pavimento, elementos de fachada para edificios y paneles de insonorización.
Objetivo
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.
