Quali-quantitative Assessment of Solid Waste Generated at Ifgoiano- Rio Verde

Abstract

Abstract On a university campus, the diversity of types of waste is substantially relevant, as there are theoretical and practical classes, laboratory and field tests, maintenance of furniture, utensils and installations, in addition to a pulsating community that uses the campus space intensively for much of its day, including its food. In view of the above, this study aimed to carry out a qualitative and quantitative inventory of the solid waste generated on the premises of the Instituto Federal Goiano - Campus Rio Verde, using the methodological procedures suggested by NBR 10004/2004 with adaptations for the campus. Nine collection points were evaluated, listed from one to nine, three of which were voluntary drop-off points (PEVs), identified as 1, 5 and 7. The remaining six were distributed around the campus in areas close to laboratories and classrooms. The evaluation period ran from February to October 2022, with two monthly collections, always on days before the municipal public service's known collection times. The research was divided into two stages, the first of which was to apply questionnaires assessing consumption and waste generation, surveying the type of material generated, the frequency of disposal, the destination of this material and forms of packaging for segregation. This was followed by a gravimetric survey of nine identified and mapped collection points. The aim was to identify the profile of waste-producing agents, the amount generated, segregated and sent for recycling, what is sent to the municipal landfill and its possibility of recovery. A total of 5,008.34 kg of solid waste was collected, of which 23.4% was thermoplastics, 11.8% cardboard, 13% food waste, and 28.9% was collected at voluntary drop-off points by recycling cooperatives. The study also found that at points 2, 3, 6 and 8, the volumes of thermoplastics and cardboard are higher than those disposed of at the PEVs, demonstrating that although there is a perception of the importance of recycling, it is still deficient. projecting for one year based on the amount found, in the area used by the Campus, an amount of 0.22t/inhab/year of solid waste generation was obtained
