Solid Waste Selective collection programs Please, could someone give make some corrections? Thanks in advance. ----------------- According to the Brazilian National Solid Waste Policy, recycling is part of the final adequate destination of waste. In order to be recycled waste goes through the following stages: selective collection, sorting and recycling. In order to get efficiency it is fundamental that waste generators segregate their waste into recycling fractions, organic fractions and tailings. Therefore, considering the importance of adequate segregation of waste by its generators, the general aim of this research is to analyze the behavior of Maringaenses people concerning selective collection and to analyze operational aspects of that collection. Operational and economic aspects of selective collection, including individual recyclable waste pickers, recyclable waste pickers cooperatives and merchants of recyclable waste were described. In order to analyze the population behavior a questionnaire was applied to a probabilistic sample of 384 households. In order to analyze operational aspects of recyclable waste collection interviews with two selective collection managers, seven waste pickers cooperatives and six individual recyclable waste pickers were carried out. In order to describe economic aspects of recycling, a questionnaire was applied to waste pickers cooperatives, individual recyclable waste pickers and merchants of recyclable waste. Results indicate that: the main difficult to segregate recyclable waste at households are lack of regularity of selective collection; trust in the selective collection program is fundamental to its success; time and effort required to segregate recyclable waste are the main barriers to the existence of an active participation in the selective collection program; participants and non-participants of the selective collection program have similar difficulties to participate actively; currently total amount of recyclable waste represents 12% of the total amount of recyclable waste that could be collected; expansion of recyclable waste sorting at cooperatives depends on more cooperatives and merchants of recyclable waste; location policy of recycling points should avoid places with no flow of people and lack of local promotion; income in recyclable waste cooperatives is similar to income of individual recyclable waste pickers; cooperatives have different physical and economic efficiencies. Suggestions for future research are proposed.
