The study deals with the reuse of Polyurethane (PU) obtained from a kitchen sponge added to plaster for use in civil engineering. The kitchen sponge is an item widely used by the population in their daily lives, generating a significant accumulation of waste. Thus, from the analysis of the properties of the kitchen sponge, it was seeking possible reuse of the kitchen sponge using it as an aggregate in plaster. The objective is to evaluate the properties of the material and consequently the search for an alternative of reuse of the waste to reduce the impact of the waste on the environment from the disposal. The methodology is composed of the collection of kitchen sponges already used, the processing, its application as an aggregate to gypsum and water, the preparation of plates for the tests and the evaluation of the properties. In general, the mixture presents significant results, highlighting excellent impact resistance and maintaining characteristics of the plaster, such as its pick time and compressive strength.
