Analysis of gravimetric composition and proposal of a solid waste management plan at a restaurant in the municipality of Iguatemi/MS, Brazil

Abstract

After the implementation of the National Solid Waste Policy (PNRS), instituted by Federal Law No. 12.305/2010, public and private institutions, along with society, became part of the solid waste management chain waste, being mandatory proper destination of solid waste from their current activities so the disposal could minimally impact environment. The objective of this work was to analyze the gravimetric composition of solid waste generated in a restaurant, located in the municipality of Iguatemi, in the state of Mato Grosso do Sul. The solid waste was collected during 06 days (from Monday to Saturday), it was weighted and performed gravimetric composition of solid waste. It was observed that the restaurant generates an amount of 79.10 kg of residues per week, 65.30 kg represented by organic matter, 6.80 kg by aluminum, 3.45 kg by paper, 2.15 kg of PET bottles, 0.75 kg of plastic, and 0.65 kg bottle caps. Of the total waste, about 80% is represented by wet waste (organic material) and 20% by dry waste (other materials). After analyzing the activities of the site and the current disposal of waste, one of the most viable solutions would be to raise the awareness of the members of this establishment about the importance of the separation of solid waste, with binary separation between dry and wet residues being purpose of facilitating the collection and final disposal, as well as composing organic material.
