RESUMO

The furniture industry plays an important role in the economy of Brazil. In 2004 exportations reached US$ 940,57 millions, according to the ABIMOVEL (Brazilian Association of Furniture Industries). Nevertheless, some of these industries have a high pollution potential, mainly generating solid residuals. The greatest furniture industry center of the Minas Gerais State, located in Ubá, has been working to find integrated environmental solutions. Many industries do not yet have any kind of environmental management and their residuals many times are being disposed off directly on the environment, disregarding the impacts cause by these actions, and neglecting the economic potential of these residuals. Thus a qualitative and quantitative survey of the residuals generated in the Furniture Center of Ubá was made to help their management. Based on this survey, this work analyzed the economic viability of the establishment of an integrated unit of the management of the residuals, called central in this work, together with a Residual Stock, with the identification of the various alternatives of operation and management that meet the conditions of the region where this center is located. The economic viability analysis was made based on the prevision of incomes and expenses of the business, the following items being evaluated: profitability, rentability, time of investment return, balance point, net present value (VPL), internal return rate (TIR), benefit/cost relation (B/C) and equivalent periodic benefit (B(C)PE). Three alternatives were analyzed: in the alternative 1, the Central is responsible for the transportations, uses the electric power of the power plant of the region, the meals are prepared and served by third parties, the class I residuals are sent to be burned by third parties, the class II residuals are disposed off in class II embankments of third parties, the workmanship workshop is used by destituted communities, and, finally, seven briquette markers with a productive capacity of 1.5 ton per work hour were used. In the alternative 2, the electric power is replaced by steam power, and in the alternative 3, besides the steam power, the central has trucks for the transportation of the residuals to be processed. It was concluded that it is viable to establish the three alternatives analyzed, and the profitability varied from 32.00% to 47.85%; the rentability varied from 2.62% to 4.87% and the time of investment return varied from 19.87 to 37 months. The smallest TIR found was of 37.49% and the greatest was of 58.62%; and the VPL was greater than zero for the three alternatives, being the smallest of them equal to R$5,851,762.26. The B/C was greater than 1 in all the cases and the (B(C)PE), that represents the remuneration (annual) of the capital, was of more than R$900,000.00 for the three alternatives analyzed.
