25. Recuperação do cromo contido nas cinzas provenientes da incineração de resíduos sólidos das indústrias coureira e calçadista visando a obtenção de cromato de sódio (VI)
O processo de transformação da pele em couro envolve uma seqüência complexa de reações químicas e processos mecânicos, no qual o curtimento representa fundamental estágio, por propiciar à pele características como qualidade, estabilidade hidrotérmica e excelentes propriedades para uso. O sulfato básico de cromo trivalente é o agente curtente pr

26. Polímeros biodegradáveis - uma solução parcial para diminuir a quantidade dos resíduos plásticos
The large use of plastics has generated a waste deposit problem. Today plastic wastes represent 20% in volume of the total waste in the municipal landfills. To solve the disposal problem of plastics methods have been employed such as incineration, recycling, landfill disposal, biodegradation and the use of biodegradable polymers. Incineration of plastic wast

27. A incineração de resíduos sólidos: análise custo benefício do incinerador de resíduos sólidos do P-sul-DF
The object of his preposition is to analyse the benefit and costs of the solid waste incineration. The conceptual frame is about the economy of the welfare, the analyses of benefit cost and the management of the solid waste. The only option of treatment of the special wastes in Distrito Federal is the solid waste incinerator in Ceilândia, and it was one of

28. Avaliação de indicadores biológicos de exposição para As, Be, Cd, Hg, Ni, e Pb em trabalhadores de incineradores de resíduos de serviços de saúde / Evaluation of biological indicators of expousure for As, Be, Cd, Hg, Ni and Pb in workers of medical wastes incineration
The biological occupational exposure indices of workers in medical waste incineration plants is evaluated. Arsenic, beryllium, cadmium, mercury and nickel (urine samples) and lead (blood samples) are studied. The measured indices are compared with (a) the limits imposed by Brazilian law, (b) limits established by American Conference of Industrial Governmenta

29. A destinação dos resíduos sólidos domiciliares em megacidades: o caso de São Paulo / Household waste management in megacities: the case study of São Paulo
The extreme complexity of the solid waste management in mega cities like São Paulo is caused not only by the great amount of waste the city generates, but also by its huge urban area.The two existent sanitary landfills located in the outskirts of the city of São Paulo namely Bandeirantes and São João receive twelve thousand metric tons of urban sol

30. The utilization of crisp code in hybrid reactor studies
One of the main applications of the Hybrid Reactors (ADS - Accelerator Driven System) is the incineration of transuranics (TRU) by fast neutrons that emerge from a spallation source in a sub critical reactor waste burner [1, 2]. For this application, an accurate description and prediction of spallation reaction is necessary, including all the characteristics

31. Influência do material e volume do porta-amostra na determinação termogravimétrica do teor de cinzas em mel
The results suggest that the two variables studied are significant and that they may be independently optimized. The material of the sample holder interferes with the incineration process only due to the amount of heat transfered. The sample holder volume aids diffusion of the atmosphere to the honey sample, minimizing the foaming effect. According to the re

32. Análise sistemática de reagentes e resíduos sem identificação
This work presents a detailed routine applied to the identification of unknown chemicals and wastes. 786 specimens were analyzed during 20 months. Unknown materials fell into three basic classes: (i) commercial chemicals without labels or illegible ones; (ii) laboratory synthesis products; (iii) used solvents (including mixtures). Uranium and thorium were re

33. Identificação multivariavel de um processo de incineração de residuos liquidos utilizando modelos nebulosos Takagi-Sugeno / Multivariable identification of liquid residue incineration process using Takagi-Sugeno fuzzy models
This work is concerned with the problem of multivariable identification of liquids residues incineration process that is a complex part of utilities unit in BASF SA. Company, located in Resende-RJ. For future works, we intend use this identification in an intelligent controller design. The choice of this process was motivated by the potential of improvement

34. Degradation of dioxinas and furanos policlorados for ligninolíticos basidiomecetos fungos and its application in biorremediação process. / Degradação de dioxinas e furanos policlorados por fungos basidiomicetos ligninoliticos e sua aplicação em processo de biorremediação.
Polychlorinated dibenzo-p-dioxins and polychlorinated dibenzofurans (PCDD/Fs) are compounds produced as by-products, unintentionally, in industrials processes and combustion processes. Municipal solid waste incineration is one major source these compounds. The isomers with chlorines substituted in the 2,3,7,8 positions are thought to cause risks to human hea

35. Plasma processing of municipal solid waste
In this paper a review and assessment of the Hot Temperature Plasma Processing of Waste is presented. The environmental advantage of this method over incineration is clearly demonstrated. The present technology of Plasma Arcs and the Modern Plasma Torches Applications are also shown. An Assessment of the Heavy Duty Gasification Combined Cycle Turbines, Gasif

36. Role of alloying elements and carbides in the chlorine-induced corrosion of steels and alloys
The high temperature corrosion of steels and Ni-base alloys in oxidizing and chloridizing environments is of practical interest in relation to problems in waste incineration plants and power plants using Cl containing fuels. The behaviour of the most important alloying elements Fe, Cr, Ni, Mo, Mn, Si, Al upon corrosion in an oxidizing and chloridizing atmosp
