RESUMO
A composição gravimétrica de um aterro de resíduos sólidos (RS) é uma informação básica para o monitoramento e avaliação de projetos ambientais. A obtenção dessa informação é dificultada pela inexistência de procedimentos padrões de amostragem, pela heterogeneidade dos RS e pela forma de disposição desses resíduos ou tipo de aterro, entre outros fatores. Esse trabalho teve como objetivo determinar se há diferença entre a composição gravimétrica de materiais aterrados em um lixão e em um aterro controlado, além de avaliar se essa composição varia com a profundidade de amostragem. Constatou-se pouca diferença na composição gravimétrica dos RS entre os aterros. No aterro controlado predominou a massa pastosa (41,2 por cento), enquanto que no lixão houve maior teor de plástico filme (35,0 por cento). A composição dos resíduos aterrados não variou com a profundidade de amostragem.
ABSTRACT
The gravimetric composition of solid waste (SW) landfill is basic information for environmental monitoring and projects evaluation. The lack of standard procedures for sampling, the inherent heterogeneity of SW and the different disposal techniques of such wastes or type of landfill, among other factors, have imposed certain limitations to obtain data about landfill gravimetric composition. The objective of this work was to evaluate the difference between the gravimetric composition of SW collected from an open dump and from a controlled landfill and to evaluate if this composition changes with depth of sampling. There was little difference between the SW collected in the two types of landfills. In the controlled landfill pasted mass (41,2 percent) was the major component, while in the open dump the plastic film (35,0 percent) was the most common material. The SW composition did not change with the sampling depth.
