Abstract: This paper evaluates the economic feasibility of a gypsum recycling plant in the Metropolitan Region of Curitiba, located in southern Brazil. The objective is to study this type of project behaviour on the Brazilian economic scenario, as all the production of gypsum powder concentrates at the Northeast of Brazil, around 3,000 Km far from south. This new market of recycling plants could diversify productive activities, could increase local incomes and taxes to municipality through construction waste materials. Knowing that a kilogram of virgin gypsum powder costs in average U$ 0.128, we studied seven possibilities to reach the economic feasibility of a recycling plant. The first four simulations varies selling prices and the three others simulations varies production. Besides that, we studied the possibility to sell the final product to neighbour states that have higher prices. The results indicate that the average selling price does not consolidate the company neither competes with the prices in the neighbour states. In order to make it feasible the product needs higher prices, which would need other economic arrangements, partnerships and new ideas to this sector that we discuss further.

Keywords: gypsum; plaster; recycling; economic feasibility.
