Analise da gestão dos resíduos sólidos produzidos no restaurante universitário do CDSA sob a perspectiva da economia circular.

Abstract

The paper presented here analyzes the management of solid waste at the CDSA University Restaurant from the perspective of the circular economy. The research aims to evaluate how waste is managed, identify opportunities for reuse, and propose strategies to minimize waste, promoting sustainable practices aligned with the National Solid Waste Policy (PNRS). The methodology adopted was an exploratory and descriptive case study, with data collection based on daily weighing of waste over a three-month period. The data were organized and analyzed to identify patterns and propose improvements. Recommended circular practices include recycling and the allocation of organic waste for pig feed. The results showed that, over three months of monitoring, the average daily waste was 7.47 kg, representing 4.85% of daily food production. Although these values are averages, there were significant peaks that suggest the need for operational improvements. The analyses highlighted variations in waste levels in different periods, with the months of July to September presenting a higher volume of waste (172 kg), while between September and October there was a reduction to 157 kg, influenced by the decrease in academic activity due to final exams. The study indicated that the implementation of circular practices, such as the use of waste for pig feed, is viable and can generate environmental and economic benefits. The practice of allocating organic waste to pig farming has proven to be effective in reusing materials and reducing environmental impact, highlighting the potential for replicating these strategies in other institutions. In conclusion, the results suggest that, despite some control over waste, there is room for optimization. It is recommended that awareness campaigns and improvements in process management, such as adjustments to menus and continuous monitoring, be implemented to further reduce waste and promote sustainability in the university environment.
