Reciclagem de resíduos sólidos urbanos em Florianópolis/SC: um estudo de caso

Abstract

This study pondered what benefits the recycling of municipal solid waste provides for the city of Florianópolis, State of Santa Catarina. To estimate the value of economic, social and environmental benefits of recycling was used the methodology of environmental valuation indicated by Motta (2006 ), which estimates the Social Net Benefit of Reuse (SNBR) obtained with the recycling of key materials in the waste collected, steel, aluminum, paper, plastic and glass. Despite the high cost of selective collection in the city, essential program for waste recycling, it was shown that recycling generates many benefits and economic gains in Florianópolis. The average SNBR estimated for market price is R$ 806,98/t, on the other hand, the average SNBR that reflects the true opportunity cost is equal to R$ 447,92/t. With the estimate of the benefit generated per tonne of each material was possible to verify the potential of recycling in Florianópolis. The potential benefits of recycling of steel, aluminum, paper, plastic and glass in 2012 were estimated at R$ 32 million, demonstrating the gain that the society would have in Florianópolis if all waste liable to recycling sent to the landfill were directed for recycling. However, only 13%, R$ 4,2 million of this amount is currently performed by recycling waste collected by separate collection and sorted by the recyclers associations present in Florianópolis. The study is divided into four chapters dealing, respectively, the theoretical framework, the concept and issues related to municipal solid waste, the methodology used and the information on municipal solid waste in Florianópolis with the results analyzed.
