Avaliação do gerenciamento de resíduos sólidos: estudo de caso em obra portuária no município de Paranaguá/PR

Abstract

The civil construction industry is one of the biggest consumers of natural resources and is the biggest generator of Urban Solid Waste (USW) in Brazil. Because it is in a marine environment and due to its magnitude and high production of CW, port works have polluting potential and can aggravate environmental degradation. By knowing the rate of waste generated, creating a waste management strategy and establishing the logistics for collecting or reusing materials, it is possible to modernize the construction industry and reduce the generation of CW. This research critically evaluated the management of CW in port construction. To this end, a follow up of 20-month was carried out on the management of the CW at Porto Dom Pedro II, in Paranaguá – PR. The port construction solid waste management process was characterized in terms of agents involved, origin, type, quantity, generation rate, reuse and destination. The waste screening process was verified through the segregation, packaging, reuse and disposal of waste. It was found that even with lectures and training on the subject, the correct segregation of waste was dependent on inspection. The working conditions that generated the greatest amount of solid waste in the construction and the proportions of CW reused in the staking construction process were verified. At the end, indicators for waste generation were defined and opportunities for improvement in the management process were proposed, which can serve as an instrument for the management of waste from future port works.
