Reducing raw material costs and minimizing the emission of greenhouse gases are emerging needs for industries, especially in civil construction, due to their predatory and unsustainable production chain. The research replaced part of the polyurethane matrix with polyvinyl chloride residues and added trihydrated alumina and cement to act as a flame-resistant thermal insulator in civil construction. Tests of water absorption, density, mechanical compression, flammability, thermal conductivity, thermogravimetry and scanning electron micrograph were performed to characterize the composites, and finally emission of carbon dioxide equivalent and production costs. The results point to good mechanical resistance, flammability, thermal stability and considerable thermal conductivity, in addition to reducing raw material costs by up to 51.49% and reducing carbon dioxide equivalent emissions by up to 49.24%. As a conclusion, the possibility of using the material in civil construction was identified, thus minimizing the impacts of waste disposal and CO2 equivalent emissions, including waste in a new life cycle, contributing to a less predatory and socio-environmentally-friendly industry.
