    Population growth and industrial and urban development have contributed to the increase in waste generation, including gypsum. Gypsum is obtained by heating the raw material, gypsum, to approximately 140°C to 160°C, followed by grinding. The speed at which the reaction occurs results in a large amount of material being wasted. Following a modification of CONAMA Resolution No. 307, gypsum became category B, waste that can be recycled or reused, making gypsum waste recycling mandatory and viable. Due to few tax incentives and the high cost involved, construction waste often ends up being deposited in inappropriate locations. This study aims to diagnose the generation of gypsum waste in construction companies in the city of Manaus, evaluate the technical characteristics of recycled gypsum produced on a pilot scale, and propose a new applicability for the ecological construction production chain. The results indicated that recycled gypsum exhibited technical properties comparable to conventional gypsum, reinforcing the feasibility of its reuse in civil construction.
