Abstract
The selective collection of domestic solid waste occurs in a fragmented and disorganized way in most parts of Brazil, through the anonymous and precarious work of informal garbage collectors. The Brazilian law 12.305/2010 (BRASIL, 2010) meets the social need for a regulatory milestone of this waste management and makes it clear the intention to include recylable material collectors. This paper aimed to evaluate the implementation of a program of selective collection of domestic solid waste with the segregation at origin and the participation of recyclable material collectors in the assistance established by PNRS (National Policy for Solid Waste). The research strategy used was a case study of the program of selective waste collection in the city of Londrina, Parana State, Brazil. The project included document analysis, visits to the sorting units and collection areas in order to monitor the data collection process. The adverse aspects of the program were concentrated on technological and health dimensions, and the positive aspects were concentrated on environmental, social, cultural, economic and political dimensions. This article provides important data and indicators to the authorities responsible for managing solid waste, leading to reflection on the actions to be implemented, and also instruction on investments and planning actions.
Highlights
The issue of urban solid waste is one of the greatest concerns of contemporary societies and a challenge to public authorities
According to information from the CMTU selective collection coordinator, to that date the collection was available to 30,000 households in the downtown area and collected up to 4 tons/day, which represented approximately 1% of domestic solid waste generated
In June 2001, CMTU promoted the removal of informal waste collectors from landfills, encouraging them to form associations, inserting them in selective collection because an individual work system was operationally very fragile to support the program and by dividing the city into units, organized by associations, there would be an organized process of data collection with the inclusion of informal collectors
Summary
The issue of urban solid waste is one of the greatest concerns of contemporary societies and a challenge to public authorities. The growing increase in this waste production comes from a pattern of unsustainable production and consumption which, along with inappropriate handling, especially during the phase involving adequate final disposal, has caused undesirable effects, and usually irreversible, from a sanitary and. According to the Federal Sanitation Department (BRASIL, 2004), from 1989 to 2000 waste production increased 49%, exceeding 100 thousand for 149 tons of waste each day and the average population growth in the period between 1991 and 2000 was 16.43%. The waste production increase was three times higher than the population growth. From 1989 to 2000, the solid waste intended for landfill disposal exceeded 15.8%
