Resumo
One of the major barriers of the selective collection projects has been the amount of waste arising from the sorting processes carried out by waste picker cooperatives. In this sense, this work is based on the qualitative and quantitative study of the generated waste in five cooperatives of recyclable pickers studied in the city of Goiânia, Goiás State, Brazil. In order to estimate the amount of waste that goes in to the cooperatives and are considered rejected, it was concluded that the specific weights were respectively 36.5 kg/m3 and 65.2 kg/m3. Regarding the rejected pile, most of the discharged materials can be characterized as potentially recyclables, among which, the percentage of plastics reaches a rate of 38%. Given the current scenario of the recyclable market, taking into account those commercially profitables (thermoplastics and mixed papers), such index reached about 40% of the rejected wastes, about 22% of all waste discharged in cooperatives. Against the recyclables are 15.2% of organic and 13.5% of rejected wastes. Analyzing, in general context, it was observed that most of the wastes that arrive (54.6%) are from rejected materials, either due to poor quality of materials, lack of market for recycling or low market value.
