In recent decades, urban development has resulted in the unbalanced production of plastic materials as waste, waste that can be reused as raw material for a new production cycle. This work presents a proposal for sustainable housing with the use of floors, blocks for sealing with thermo acoustic blanket and sustainable tiles. For their preparation, rotational molding and compression molding equipment was assembled. Residues of polymers and natural fibers were used to make these constructive elements. The polymers used for the development of the floor were polystyrene (PS) disposable cups; ecological blocks were modeled and processed from post-consumer polypropylene (PP) and high-density polyethylene (HDPE) packaging; tiles were molded from discarded laminates; the floors became resistant to abrasion due to the presence of babassu fibers. The blocks provided acoustic comfort by including açaí fiber blankets, the walls were assembled using blocks and a commercial product for laying and overlapping. Housing as a model for recycling materials discarded in the environment will be able to generate proper disposal, providing income, increasing the life cycle of these materials, producing ecological products in civil construction and meeting at least four of the Organization's Sustainable Development Goals-SDGs of the United Nations.
