SUMMARY:

Modern polymers are versatile materials, they reach a wide range of applicability, they are resistant and low cost, which makes plastic indispensable for human development, since modern society is marked by before and after its discovery. They have magnificent characteristics that have led them to be used in practically all consumer goods. However, the improper disposal of post-consumer plastic waste generates environmental pollution, since recycling is not always viable nor is there adequate management of the final disposal of this waste. Environmental pollution from plastic waste affects the entire land surface and marine environments,
directly impacting human health. If on the one hand we have a growing world population highly lacking in materials, on the other we have finite sources of non-renewable natural raw materials, creating the need to develop more efficient and sustainable materials, especially in the field of civil construction. The application of plastic waste as a construction material appears as a possibility to reinsert it into the production chain within the circular economy model aiming at socioeconomic development and sustainability. Therefore, we sought to develop a sustainable brick, replacing materials such as clay and concrete, with a polymeric composite of polymeric waste, such as polyethylene (PE), polypropylene (PP), etc., and construction sand. In the study, the
polymeric waste and sand were processed in an intensive mixer in different proportions, after melting, molding and demolding, the specimens were tested for their mechanical properties of resistance to variation, water absorption and hardness. Infrared, thermogravimetric and scanning electron microscopy characterization analyses were performed. The polymer-ceramic composite bricks demonstrated equal or superior performance to traditional bricks in the trained periods, and can be an alternative and innovative material, providing sustainability, avoiding environmental impact and contributing to the circular economy.
