Abstract. To address the current demand for materials with good mechanical performance for construction applications that are environmentally friendly, the improvement of the mechanical properties of gypsum plaster using recycled cellulose obtained from multi-layer waste containers is investigated. Gypsum is an important material in construction that is used as a retardant agent for setting concrete, plaster and bonding material. Gypsum is also used for prefabricated panels, which are good for flame resistance. Multilayer carton (i.e. Tetra Brik®) is an important part of municipal solid waste; however, it is not recycled in large volumes due to the complexity of its recovering. In recent years, new methods have been developed to recycle multilayer carton, which includes the hydropulping process. This method allows recovering the cellulose, which can be used as reinforcement for plaster made of gypsum. In this work, a composite material based on gypsum reinforced with recycled cellulose, which is obtained from multilayer carton containers using the hydropulping process, is investigated. Gypsum/cellulose plaster samples were fabricated at fiber concentrations of 0%, 1%, 2% and 3%, in weight fraction. Flexural tests performed on the plaster showed an improvement of the mechanical properties with low proportion of cellulose (<4%) when compared to plain gypsum plaster. These results show that recycled cellulose/gypsum plaster is an interesting option for construction applications with improved flexural strength.
