Resumo
In Brazil, plaster recycling has been growing since the change in resolution 307 of the National Council of the Environment (Conama), which since 2011 classifies plaster as a recyclable product. Thus, the industries generating this type of waste are responsible for properly targeting them. The main ways to recycle plaster are: reuse for soil repair in the agricultural industry and calcination, therefor, the waste can be reused again in the civil industry. This work studied the temperature for calcination and the contamination of the residues of the production of plaster angles, to verify the feasibility of recycling with a lower possible energy consumption and, also for the use of these particles as dispersed phase in new composites. For this, XRD, FTIR tests were carried out and the grain size obtained after the plaster recycling was determined.
