RESUMO

The generation of chemical waste in industry is very high, therefore the effluent discharge has been monitored by environmental inspections with greater intensity, to avoid environment contamination. The volume of waste generation is very small in universities, but the diversity is too large, what makes the treatment more difficult. Nevertheless, there are a growing number of universities concerned to establish management programs for their wastes. These initiatives include environmental care, concerning to give a good example for their graduated professionals and a continuous quality control program. The Chemical Waste Management Program (CWMP) implemented at CENA/USP from 2001, is permanent and requires constant innovation and improvement, as each year new projects are being implemented, resulting in the generation of wastes that werent cause for concern. However, chemical wastes treatment initiatives in the Isótopos Estáveis Laboratory started in 1999. In this context, this dissertation aimed to: 1 - quantify and qualify the laboratory waste conditions and the behavior of the population responsible for the waste generation at CENA/USP, 10 years after the CWMP implementation; 2 solve CWMPs problems that are not still resolved for the treatment of some wastes, developing treatment methods for chrome, acetonitrile and to propose adjustments to the problems from the program evaluation; 3 - extend the chemicals knowledge used in the CWMP routine, in a practical and didactic way to a State High School students from Piracicaba-SP, such as: chemicals identification, chemistry safety, recycling and reuse. In general, the waste generators were well-informed and willing to promote the program principles, but showed the need for greater disclosure of program actions. However, two non-conformities were found in the effluent discharge, in which were taken the appropriate actions. Methods for chemical precipitation, chromium inertization and treatment through acetonitrile alkaline degradation were established. The extension works contributed to teach chemistry to first-year students of a State High School in Piracicaba-SP and for the staff involved in the project, which was composed mostly of post-graduation students who tried this experience as well
