Reaproveitamento de resíduos da indústria têxtil em massa cerâmica: estudo de caso

Abstract

According to CONAMA Resolution No. 01 of 01/23/86, pollution can be defined as any change in the physical, chemical and biological properties of the environment resulting from human activities that, directly or indirectly, affect health, the safety and well-being of the population; social and economic activities; the biota; aesthetic and sanitary conditions and the quality of environmental resources. Residue can be termed as any material left from a production, which is no longer useful, and which is normally discarded and treated as unwanted by several companies. According to ABNT NBR 10.004/2004 on the classification of solid waste, it is the result of industrial practices, which may present characteristics of combustibility, biodegradability, and that, when in contact with certain materials, suffers contamination, and may assume toxic properties. In Brazil, the concern with discarded products is still incipient, and there is a lack of facilitating mechanisms for textile reuse and recycling processes. Consequently, a large part of these are destined for sanitary landfills, dumps and incineration. Therefore, the use of waste from the textile industry, as the sludge that is decanted in the decantion tank of the Effluent Treatment Station, in the application in the ceramics industry for incorporation in ceramic mass for the production of block can be made possible by replacing one or more raw materials of the original composition for a waste, keeping the production process the same as it was normally used in order to maintain the properties of the original product while preserving its original quality.
