Descripción del proyecto
Un proceso de mineralización de la madera bioinspirado y resistente al fuego
La madera, aunque renovable, es combustible, lo cual plantea un reto en la construcción. Los ignífugos tradicionales, aunque eficaces, suelen ser tóxicos y se filtran al medio ambiente. La mineralización de la madera, un método alternativo, puede resultar cara e implica el uso de productos químicos nocivos. La mineralización inducida por microbios ofrece una solución sostenible, pero los hongos, en comparación con las bacterias, siguen estando poco explorados en este sentido. El equipo del proyecto MICRO-INSERT, financiado por las acciones Marie Skłodowska-Curie, pretende colmar esta laguna utilizando hongos como portadores de carbonato cálcico para mineralizar la madera, creando nuevos materiales híbridos orgánico-inorgánicos con propiedades mejoradas, entre ellas una mayor resistencia al fuego. Este proceso fomentará el diseño de materiales sostenibles y la circularidad. El equipo del proyecto facilitará la transferencia de conocimientos mediante el establecimiento de una sólida red de investigación, la organización de actos y la tutoría de jóvenes investigadores.
Objetivo
Wood is the only renewable construction material and holds great promise for sustainable built environments of the future. However, its combustibility is a major limitation. The drawback of using traditional fire and flame retardants is the toxicity and volatility of some of their components and the loss of chemicals by leaching, leading to poorer performance. Mineralisation of wood offers a green alternative, but current strategies often require a costly technical setup for supercritical gases or the use of harmful chemicals to achieve the deposition of minerals deep inside the wood structure. Biologically induced mineralisation is a widespread phenomenon occurring in all kingdoms of life. In recent years, microbially induced calcium carbonate (CaCO3) precipitation has been proposed as a potential solution to address many environmental and engineering issues related to the enhancement of inorganic materials (protection of concrete, soil consolidation). However, the potential for using fungi has received relatively little attention compared to bacteria. The MICRO-INSERT project will investigate the feasibility of using fungi as CaCO3 carriers to develop a novel bioinspired mineralisation process for biobased building materials. Wood as a highly porous, three-dimensional organic scaffold will be mineralised to create hierarchically structured organic-inorganic hybrid materials with novel properties, including improved fire resistance. The proposed bioinspired treatment incorporates ideas for sustainable materials design, circularity, reduction of toxicity, and lowering the negative impact on the environment. The MICRO-INSERT project will stimulate innovation and knowledge transfer between the host and ER by building a solid research network, organising events, mentoring young researchers, and managing projects. The ER will gain research and scientific skills and acquire a new set of competencies to reach professional maturity and independence after the fellowship.
