Composição gravimétrica dos resíduos sólidos domiciliares de Fortaleza/CE dispostos no aterro sanitário de Caucaia/CE

Abstract

There were realized field trials during the second half of 2009, in an operating cell of the landfill that receives solid waste from Fortaleza/CE. Supported by a platform scale with capacity up to 150Kg, a 12m² canvas and a 100L barrel, the samples were removed after the arrival of the truck in the landfill attendance and consequent eviction of the newly waste collected. Worked up with ten different samples (12.5, 50, 75, 100, 125, 150, 250, 300, 500 and 750Kg). The results show that, on average, 47.5% (by weight) of solid waste deposited in landfill are organic materials, 14.2% are paper / cardboard, 8.7% are plastic film, 7.0% are hard plastic (including PET), 6.4% are others (diapers, sand, Sanitary Pad, Styrofoam etc.), 3.3% are metals, rags are 3.2%, 3.0% are rubber, 2.6% are packaging tetrapak, 2.2% are wood and glass are 2.1%. These data show the great wastage by part of the population in Fortaleza and, on the other hand, represent a whole scenario of social, economic and environmental possibilities, as most of the selected waste has the potential for composting and recycling (saving natural resources, creating new jobs, damaging less the environment and building new social values).
