Abstract
Two new recycled gypsum boards are proposed which have a better environmental performance due to the fact that they are made of traditional materials and new recycled ones derived from biomass (waste generated during the extraction of olive pomace) and the coal combustion produced in power plants. Before using these wastes as raw materials, they have been submitted to chemical analysis and the panels made of them have been tested to prove their mechanical, thermal and fire performance. Subsequently, the new recycled panels have been implemented in a traditional facade solution to verify their functional and thermal feasibility. Finally, the results obtained show that the panels made of biomass ashes have a better mechanical and thermal performance than those made of coal ashes and that they can provide a sustainable alternative to the traditional facade materials due to its lower environmental impact based on the reduction of raw materials consumption and industrial waste. The new materials comply with the specifications of Spanish Technical Building Code in the region evaluated

Con el fin de establecer un proceso de reutilización de residuos procedentes de la combustión de biomasas en construcción, al no existir una legislación específica en España que establezca que ensayos y límites deben cumplir los materiales de construcción que incorporan residuos, se ha optado por seguir los pasos establecidos en la legislación holandesa
Acumulados según se indica en el ensayo NEN 7345 de los paneles, cuyo objetivo es simular el lixiviado de componentes inorgánicos en materiales conformados y monolíticos en función del tiempo
