This paper studies fired clay bricks made by using waste pomace from wine industry as an additive in brick production. The aims are both, studying bricks properties and showing a new way of pomace recycling. Several test specimens were made by using different percentage of additive. These samples were subjected to the corresponding assays in order to determine the maximum additive percentage to be added according to standards. It has been confirmed that the amount of pomace that might be added is limited to 5%, whereby brick's water absorption and compressive strength comply with standards. Therefore masonry structural requirements are preserved at the same time that collaterally a better insulation of the buildings enclosure is achieved by reducing its thermal conductivity up to 25%.
