Gerenciamento dos resíduos sólidos orgânicos da UFGD através da compostagem

Abstract

One way to solve the problems related to the organic solid waste is the management and the management of those. Composting represents a viable and promising alternative, as it enables the reuse of these residues, besides generating organic fertilizer at the end of the process, which has various applications. The objective of this study was to identify is viable to use compost in the treatment and management of organic solid waste generated in the campus of Federal University of Grande Dourados (UFGD), Dourados, Mato Grosso do Sul. The experiment was done in the Social Technologies Incubator and solidarity of the Federal University of Grande Dourados (ITESS / UFGD). The windrow composting was drawn up using the same methodology as used in the Federal University of Santa Catarina (UFSC), (and tested earlier in UFGD, however, in another weather station) called thermophilic composting in static windrow with natural aeration. The mounting of the windrow was performed using small tools such as shovels, hoes, scale, and organic waste such as food scraps from the University Restaurant (RU), waste animal houses, such as rat and rabbit bed, campus grass clippings, biological inoculant and dry branches. Before daily replacement of organic material, the temperature of the windrow was measured in order to ensure the occurrence of its gradual increase. The experimental windrow drawn up UFGD proved the efficiency of thermophilic composting process in static piles with natural aeration for the treatment of organic solid waste generated in Campus, showing it a great alternative to the allocation and proper treatment of these materials, besides being a process easy to use and low cost.
