Abstract
Introduction. Universities with chemical analysis laboratories manage, of course, chemical
substances and make diverse operations that generate residues which are, in most of the cases,
dangerous for human health and the environment.
Objective. To achieve an adequate segregation of the residues generated in the Environmental
and Sanitary Engineering laboratory of the University of the Cauca.
Materials and methods. In order to establish this new classification alternative, several activities
were done, among them a wide bibliographical research and an analysis of experiences,
activities developed in the laboratory, clarity in the moment of the segregation, easiness of
recovering and reuse of waste, among others.
Results. the outlined alternative classifies and gathers the chemical waste inside the laboratory
in groups and subgroups according to each practice or laboratory activity to be developed
during the semester.
Conclusion. the outlined alternative allows gathering, in an appropriate way, the residuals generated
in laboratory practices, allowing its easy recovery and potential reuse. It also facilitates
to identify dangerous and not dangerous residues and, with the application of this alternative,
several useful assets have been recovered such as: copper sulphate, potassium chromate,
ethanol, disinfectant solutions, saline solutions, acid- base solutions, silicon dioxide, manganese,
dioxide and sulphur.
