Gerenciamento dos resíduos passivos do laboratório didático de microbiologia da UFC: um estudo de caso

Abstract

The management liabilities chemical residues is an issue that is currently gaining increasing importance. This is due to the fact that once performed incorrectly (handled and disposed incorrectly) can compromise the natural resources such as water, soil and air. Chemical residues include several products as reagents past due or in disuse; waste from practical classes and research projects. Thus, their presence and accumulation are common in laboratory environments and thereby mainly at universities. It is therefore of fundamental importance to the presence of a residue management program within universities. An example of a waste management program in operation and which was established in 2005 at Universidade Federal do Ceará(UFC) is PROGERE- UFC( Programa de Gerenciamento de Resíduos) Therefore, this study was done: "Management of Educational Laboratory liabilities residues Microbiology UFC: a case study", which was carried out in the current Annex to LAMAB (Laboratório de Microbiologia Ambiental) and in partnership with the PROGERE -UFC. Previously, this was a teaching laboratory of Microbiology, which was transferred to a new block and in that this site was attached search. During the teaching laboratory transition for attachment research, it was found the presence of several disorganized passive materials and stored incorrectly mode. Thus, with the guidance of PROGERE, this material was inventoried and organized into boxes according to the chemical incompatibility observed in FISPQ's (Ficha de Informação de Segurança de Produto Químico) or MSDS (Material Safety Data Sheet), tables provided by PROGERE and by consulting of Plano de Gerenciamento de Resíduos Sólidos( PGRS) of Embrapa( Empresa Brasileira de Pesquisa Agropecuária). In addition, it was separated in identified reagents and chemical residues and those which there were labeled necessity. 20 boxes were inventoried in total, being identified reagents and 5 of residues( boxes 16-20), totaling 237 passive materials. Identified reagents were registered in PROGERE reagents bank and some residues were neutralized (For example Sodium hydroxide and Hydrochloric Acid). This case study was important and reached their goals, since it results in a better management of these chemical residues, providing traceability and dispose of some waste.
