Urban Solid Waste Management in Caxias Do Sul/Brazil: Practices and Challenges

Abstract

Abstract:Solid waste management is becoming a challenge for the cities' authorities in developing countries mainly due to the rapid economic growth and population increasing. In cities of the developing world, the informal sector plays an important role in the management of urban solid waste. This work examines the participation of scavengers in an integrated municipal solid waste management system. The paper is based on direct field observations, interviews with scavengers and characterization of the urban solid waste generated in Caxias do Sul. The partnership between municipal government and local scavengers were also evaluated as well as the contribution of the scavengers in the urban solid waste management system. The study reveals that it is necessary to realize a campaign for improving the waste segregation at source. The infrastructure of the scavengers associations need to be improved and finally the scavengers need to be more deeply involved in the policies associated with the urban solid waste management system adopted in the city.

Percepción ciudadana sobre el sistema de recolección de desechos sólidos mediante ecotachos en el barrio San Alfonso, cantón Riobamba

“…Además, se conoce que sólo el 19,8% de municipios de la región poseen planes de Gestión Integral de Desechos Sólidos (GIDS), y que únicamente el 2,2% cuentan con programas formales de reciclaje, otorgando los municipios esta responsabilidad al sector informal, como una alternativa de generación de ingresos, aunque la mayoría de veces, en condiciones precarias e insalubres (CNC, 2019, p.12). Debe señalarse además que, como refieren Poletto et al (2016), la labor de los recolectores debe visibilizarse aún más en la elaboración de la política pública relacionada con la gestión de los desechos sólidos en las ciudades, sobre todo en las naciones en desarrollo.…”

Policy Implementation of Solid Waste Management by The Environmental Office of Bekasi Regency

“…Today, one of crucial issue that should be addressed by an ideal policy is solid waste management, an inseparable part of environmental issues. Solid waste management is an effort to manage solid, used objects, either organic or non-organic waste, including plastic, metal, and paper, as well as household and industrial waste, through various processes (Nnaji, 2015;Pires, Martinho, Rodrigues, & Gomes, 2018;Poletto, De Mori, Schneider, & Zattera, 2016;Rajesh, 2019;Vyas, 2010;Yetis et al, 2015).…”

An application of the augmented ε-constraint method to design a municipal sorted waste collection system

“…The rise in world population and the associated increase in urbanization have put pressure on the management of Municipal Solid Waste (MSW), which is regularly associated with various environmental, social and economic problems (Poletto et al, 2016;Troschinetz & Mihelcic, 2008). These problems intensify in developing countries, due mainly to budgetary and technological restrictions.…”
