Quality-Quantitative Identification of Dangerous Waste From FOB-Usp: Waste Management

Abstract

Hazardous waste is defined by the Environmental Protection Agency of the United States (EPA) as any waste that because of its quantity, concentration, physical, chemical or infectious characteristics, may cause or significantly contribute to increased mortality, serious irreversible or incapacitating reversible diseases, or pose a present substantial or potential hazard to human health and the environment when improperly managed. Aiming to comply with the laws, the Bauru Dental School (FOB) in 2003, installed its first Laboratory of Chemical Waste (LRQ). However due to increased demand and new waste generated, there was the need to build a new laboratory. Therefore, this study conducted a qualitative and quantitative survey of hazardous waste generated in different sectors of the FOB, Hospital for Rehabilitation of Craniofacial Anomalies (HRAC) and Prefecture of Campus, beyond its current mode of handling by responsible. This survey was conducted through a questionnaire. After analyzing the data, we saw that were generated 433 liters of waste in 2013, mainly: developer liquid, fixer liquid, alcohol, ethylenediaminetetraacetic acid (EDTA), xylene and formaldehyde. In addition, we found the key points for a better management of waste. This work was important to quantify and qualify the hazardous waste on the USP campus of Bauru. The implementation of a specialized laboratory in management and treatment of waste on campus, for the recovery of these, beyond to proper disposal, is important for both environment and people.
