Caracterização de resíduos líquidos na produção de painéis de fibra de madeira de média densidade

Abstract

This study aimed to characterize the liquid effluent from a secondary processing plant wood paneling, medium density established in the state of Paraná, with a processing capacity of 300 000 m³ / year, accomplished through analysis of the life cycle of the process, based on environmental legislation in the country, which characterizes and sets the parameters for release and disposal of wastewater prescribed according to the National Council on the Environment, through Resolution No. 357 of 17 March 2005 taking into account the mapping chain through flowchart of steps inherent in the object of this study and description of the main activities of the process beyond the identification of inputs and outputs. The average water consumption in factories panels average density is approximately 0.20 m³ / m³ produced. However, there is a consensus in the industry, there is a strong environmental pressure to reduce water consumption, thereby underscoring the importance of this study.
