In Spain, Universitat Politècnica de Catalunya researchers have developed and patented a type of biological concrete that supports the natural, accelerated growth of pigmented organisms. The material, which has been designed for the façades of buildings or other constructions in Mediterranean climates, offers environmental, thermal and aesthetic advantages. The material consists of a conventional carbonated concrete and a magnesium phosphate cement that are layered to provide a space for the growth and development of certain biological organisms, to be specific, certain families of microalgae, fungi, lichens and mosses. The resulting façades regulate thermal conductivity, absorbs and reduces atmospheric CO2, and adds a unique architectural color and texture to buildings.
