Efetividade da coleta seletiva solidária para alunos de graduação da UTFPR - Londrina: aspectos ambientais e de sensibilização

Abstract

Universities are considered large generators of solid waste; therefore the implementation of the SWMP is required (Solid Waste Management Plan), in order to guide the actions regarding the management and disposal waste. Moreover, according to regulation 5.940/2006, federal public institutions must necessarily implement the Joint Selective Collection (JSC), ensuring the separation of recyclable waste at source, which involves awareness raising for continuous and permanent training of individuals aware and responsible for their citizens obligations. In UTFPR Campus Londrina JSC has been held since 2012. Thus, the objective is to evaluate its effectiveness from the aspect of segregation of recyclable waste and awareness of the student community. Therefore, it performed the physical characterization (gravimetric composition and specific weight) of recyclable waste generated in the institution over a month and the quality assessment of discarded materials. Furthermore, to assess the community's awareness of the JSC, 321 undergraduate’s students responded to an online questionnaire that included questions that sought to identify the students' knowledge about the JSC and its importance attached to this work, the form of participation of students the proposed actions as well as the most effective strategies in the process of awareness and a knowledge test as to the allocation of recyclable waste generated in the Campus. It was observed that the prevalence of generating recyclable waste by weight is paper and that there are still challenges to be overcome in the item source separation, due to the percentage of waste type waste observed. The specific weight data showed higher standard deviations, which indicates the need for on-site survey of this parameter for the purpose of packagers sizing projects and waste shelters, for example. As for the quality of recyclable waste produced by Campus noticed that the washing practice before disposal is underachieved, which implies odor problems and vector attraction. It was observed that the JSC is well known and appreciated by the students, especially the daytime courses. Among the strategies used to raise awareness solidarity actions received greater emphasis in terms of efficiency and compliance. As for the knowledge test, 52% of students who answered the questionnaire had more than 70% accuracy.
