The search for technical and economic feasibility of waste recycling in the production chain of construction, come meet the changing industry needs to promote an integrated economic growth to social and environmental needs. The increasing consumption of plasterboard sheets carries with it the problem of the generation of gypsum waste, where the lack of research and incorrect disposal just allocating the waste generated, in most cases, to landfills, or irregular dumps without control or estimate of volume. This work through the adoption of a recycling process, comprising the steps of grinding and calcining the residue of plasterboard sheets, determined the physical and mechanical properties of recycled gypsum from the drywall sheets. The results showed the feasibility of recycling, because after rehydration was possible to mold solid specimens using only the gypsum waste. After more specific studies it is clear that certain percentage can be reincorporated as a raw material in the production process of plasterboard sheets, plasterboard or plaster moldings, demonstrating that it is possible to recycle a product that today is merely discarded in the environment. |
