Resíduos de coco, acerola e caju para produção de carvão ativado

Abstract

With the growth of industrial activities and population, also increases the amount of generated waste which causes environmental problems. In Brazil, a major producer of goods in the agricultural industry, the problems caused by the accumulation and improper disposal of solid waste are large. From this problematic, mechanisms that encourage the reuse and recycling of waste are created. It is seeking to develop new technology of alternative raw materials that are produced activated carbon from coconut waste, barbados cherry and cashew. Primarily, the collection of fiber-to-dry coconut and cake/shells from barbados cherry and cashew for later preparation of this material by impregnation with ZnCl2, chemical activation and conducting an evaluation test coal efficiency. The result, within all samples, was an activated carbon where the application in the water sample collected from the Capibaribe River (near Chico Science tunnel), Recife, presented a decrease in turbidity in 97.3% using treatment with 25% fiber- coconut + 75% cashew.
