“…After breaking, the raw scoria pieces were weighed, and cathode and anode pairs with similar masses were formed. The characterization of the raw iron slag has already been reported in previous work by Bragagnolo et al (2018), and the main constituents of the material are presented in Table 1.…”

The Indigo Blue dye is widely used in the textile industry, specifically in jeans dyeing, the effluents of which, rich in organic pollutants with recalcitrant characteristics, end up causing several environmental impacts, requiring efficient treatments. Several pieces of research have been conducted in search of effective treatment methods, among which is electrocoagulation. This treatment consists of an electrochemical process that generates its own coagulant by applying electric current on metallic electrodes, bypassing the use of other chemical products. The objective of this work was to evaluate the potential use of iron slag in the electrocoagulation of a synthetic effluent containing commercial dye Indigo Blue and the effluent from a textile factory. The quantified parameters were color, turbidity, pH, electrical conductivity, sludge generation, phenol removal, chemical oxygen demand (COD), and total organic carbon (TOC). The electrocoagulation treatment presented a good efficiency in removing the analyzed parameters, obtaining average removal in the synthetic effluent of 85 % of color and 100 % of phenol after 25 min of electrolysis. For the effluent from the textile factory, average reductions of 80 % of color, 91 % of turbidity, 100 % of phenol, 55 % of COD, and 73 % of TOC were measured after 60 min of electrolysis. The results obtained demonstrate the potential of using iron slag as an electrode in the electrocoagulation process in order to reuse industrial waste and reduce costs in the treatment and disposal of solid waste.

The generation of large amounts of ash from sugarcane bagasse by its producing countries is becoming a worldwide-problem. Its irregular application, such as in fertilizers, contaminates soil and water, causing a great environmental problem. Studies show it is possible to apply ash in some specific areas, such as replacement of portland cement, replacement of clay, as an adsorbent, in the treatment and stabilization of soils, in the pavement of road asphalt, among others. The objective of the present article is to evaluate which are the most promising areas for the use of sugarcane bagasse ash. The work was developed with a bibliographic search, using the bibliometrics technique. The results obtained show that it is possible to use ash in several different areas. However, having a detailed study of the characteristics of the ash obtained is important, because they are directly related to the regions and climates where sugarcane is cultivated, besides its granulometry, collection time the ashes in the boilers, pHs, curing time, etc. In conclusion, results can be very different for the same application area, depending on the properties of the ash obtained.
