Cathode ray tube monitors The CRT used in television and computer screens represents one of the main sources of e-waste as flat screens have replaced them over the last ten years Lecler et al. Cathode ray tube monitors were collected for these experiments; their manufacturing year varied from to Such a productive increase demands a large amount of raw material which generates 1005 problems related to the scarcity of natural resources.

As stated by Okadaa material containing lead may scatter and result in oral intake of the dispersed lead by humans, which ultimately results in health problems. Characteristics of fired bricks with co—combustion fly ashes. Coal mine wastes recycling for coal recovery and eco—friendly bricks production. It should be noted that XRF determines the atoms present in the sample and not the compounds. Iron oxide is known to favor reddish tones in the burned parts and by the fluxing effect in the ceramics.

This dam is located in the county of Mariana and it is mainly used to retain the waste resulting from the iron ore treatment at the Germano Plant. Effect on aesthetic quality and physical properties. However, increasing the value of by-products using the waste recovery methodology has been a sustainable alternative to avoid their disposal in soil conditioners or landfills. After the burn, the samples were characterized 1000 linear retraction of burning, loss of ignition, mechanical resistance to flexion diametric compression in a universal machine of mechanical tests EMIC model DL and water absorption.

Publications Office of the European Union; The economy already gives indications that will grow again which will improve the construction market. Geological assessment and utilization with drinking water treatment sludge in brick manufacture.


As the waste content increases it also increased retraction, because of the waste having considerable qbnt of fluxing materials as shown in Table 2which aids in the fusion of the piece, causing the retraction. Services on Demand Journal.

Chemical pollution of aquatic environment by priority pollutants and its control. Influence of adsorbed anions on the dehydroxylation of synthetic goethite. It is clear that recycling waste of CRT is important not only for mitigating environmental issues, but also for maximizing the value of the waste Abtn et al.

Chemical and mineralogical characterization tests of the raw materials carried out. The graph of Figure 2 shows the results of total linear 100005 retraction drying and firing of the formulations and standard mass STD used in the study.

The next step was intended to evaluate whether the lead removal had been able to convert the CRT from a hazardous waste to a ant waste according to the Brazilian regulation. Pollution causes, effects and control. The results from the AAS obtained from the samples that had undergone the thermal process are displayed in Table 6. This content is the standard for the accomplishment of the conformation of the specimens.

For this procedure the weighings of the Standard Mass STD and also of the waste were carried out with a abnnt electronic mark, model SF with a maximum capacity of 10 kg. The CRT used in television and computer screens represents one of the main sources of e-waste as flat screens have replaced them over the last ten years Lecler et al. Reducing the amount of pores favoring the reduction of water absorption and the increases of the mechanical resistance. Journal of Thermal Analysisv.

Mainly because it contains significant quantities of heavy metals lead and cadmium and considerable proportions of aluminum.

August 24, Correspondence: Natural clay substitution by calamine processing wastes to manufacture fired bricks. MedCrave Group is ardent to provide article reprints at an instant affordable Read more How to cite this article. Wastes that are not characterized in the NBR should be classified according to their leaching potential, which is evaluated using the NBR Constrution and Build Materials. Currently produced ceramic coatings are generally composed of three distinct layers: Thus, the lead removal conditions were not effective to downgrade the hazardousness of the waste.

Polluting potential of Samarco Mineração S.A. solid waste: a Germano dam case study

Surface properties of new green building material after TiO2—SiO2 coatings deposition. Which for companies this is of fundamentally important because it guarantees the quality of the final product. However, given that the sample was glass, the XRF equipment assumes the atoms are in their most oxidized state – resulting in the chemical compounds shown in Table 4. Therefore, recycling or re-use within the same process can be a reasonable way of preserving the environment.

The obtained results encouraged a study regarding the hazard potential of CRT monitors. The ceramic mass supplied by a ceramic company from South of Santa Catarina, Brazil used for the manufacture of structural blocks.

The XRF results from CRT parts confirmed that lead is present in the funnel and in the neck while the panel is lead free, as shown in Table 4. Table 4 presents the results of the Raw Residue of the STD and enamel waste, showing that the residue used has a smaller particle size than the standard mass, directly aiding in the packaging factor, contributing to a better compaction.

The annual global of ceramic for masonry production is currently around billion and its demand is expected to grow steadily.

This factor causes the number of researches to increase the incorporation of a series of residues in ceramic mass, such as glass, 1415 ashes of the most diverse sources, 16 mining wastes, 19 sludge from a wide variety of treatment sources, 20 waste from heavy clay agnt process 23 and other wastes.
