| Abstract | |
The research centers simply cannot dissemble that in the development of their activities are also generated significant amounts of wastes. This attitude is contrary to the role played by them in society, as they must do research with respect to the environment. Thus, this study aimed to establish a plan for waste management generated in the APTA Center South Pole. Therefore, previous surveys involving the characterization of active and passive wastes, as well as their sources, contributed to guide the actions taken, mainly for the segregation, recycling or treatment proposals, comprising laboratory chemical waste, pesticides and solid wastes. The passive inventory related to pesticides resulted a list of 104 active ingredients, among which 16 with ban proposal, restrictions or banned, stored in inappropriate conditions. Moreover, 55% was represented by expired products. This inventory was the basis for planning a new warehouse for the storage of these products. In the active inventory related to laboratory chemical wastes was observed the generation of wastes containing metals such as chromium and copper, and acid or alkaline solutions. The chemical precipitation technique employed for removal of metals given to treatment efficiencies exceeding 99.9%, allowing meet the limits established by CONAMA Resolution n° 357/2005 at a low treatment cost. The results of the Waste Collection Program were also satisfactory. Its implementation began with the application of a structured questionnaire to the APTA Center South Pole community, which had a participation rate of 91%. The waste diagnosis showed that are produced 6.8 kg day-1 on average of solid wastes, representing a daily per capita production of 151.3 g. The largest waste fraction, in % by weight, is related to organic wastes. An Environmental Education event was attended by over 50 participants, who evaluated it as excellent (80%). The indicators used to evaluate the program demonstrated that there was a reduction in total waste generation of 42% and 57% per capita and, the replacement of one-way plastic drinking cups for mugs received adherence of all the community. Moreover, the paper generation and the consumption of disposable products were reduced by 57% and 100%, respectively. Within the Program, a system for producing deionized water was also developed, which had a production capacity of approximately 7200 L of water with excellent quality (0.9\'mü\'S cm-1). The achievements of the WMP are promising and demonstrate that it has provided immeasurable environmental gain. Finally, it stands out the importance of continuous support by APTA Center South Pole board for the maintenance and constant improvement of the WMP (AU) | |
