Chemical waste management in academy: multivariate analysis as planning tool

Abstract

The waste management in a university requires actions like collection, classification, segregation and treatment or final disposal for waste generated by teaching, researching and extension activities. The Chemical Waste Management Program (CWMP) of Federal University of Lavras recorded its activities during 2010 and 2011, identifying the types of collected waste according to the origin, volume and treatment, throughout the months of each year. All these data were interpreted using multivariate analysis as tool, on mode Principal Component Analysis (PCA), aiming to define strategies for the Laboratory of Chemical Waste Management (LCWM) operation logistic, responsible for the CWMP. The logistics of waste collection and treatment was defined based on departments and types of waste received, identifying the place and type of waste collected each month. Thereby, it was possible to define an operation strategy for CWMP, optimizing the chemical waste management in the academic environment.
