1. Integração do processo de cristalização de frutose por adição de antissolvente
Fructose (C6H12O6) is a monosaccharide with increasing industrial interest, and with some advantages over other sugars, facts that have motivated many studies about its production from its aqueous solution, by crystallization. Fructose crystallization occurs, in general, with the addition of ethanol as anti-solvent, aiming the reduction of its solubility and

2. Caracterização cromatográfica de compostos orgânicos presentes nos resíduos sólidos provenientes de indústria de reciclagem de papel e sua aplicação na produção de briquetes de carvão vegetal
Recycling of paper in industrial scale has become an established practice worldwide. In this work, organic compositions of three different kinds of sludge generated in recycle paper industry were studied, and the incorporation of one of those sludge in briket was also investigated. The characterization of organic compounds in sludge samples and briket was pe

3. Stabilization of electric-arc furnace dust in concrete
Electric-arc furnace dust (EAFD) is a by-product of steel production and recycling. This fine-grained material contains high amounts of zinc and iron as well as significant amounts of potentially toxic elements such as lead, cadmium and chromium. Therefore, the treatment and stabilization of this industrial residue is necessary. Concrete is a well-known suit

4. Estudo do potencial de utilização do resíduo da extração de esmeraldas na fabricação de cerâmica de revestimento / Study of the potential use of waste from the extraction of emerald in the manufacture of ceramic tile
Companies involved in emerald mining and treatment represent an important area of industrial development in Brazil, with significative contribution to the worldwide production of such mineral. As a result, large volumes of emerald waste are constantly generated and abandoned in the environment, negatively contributing to its preservation. By the other side t

5. GestÃo e caracterizaÃÃo dos resÃduos sÃlidos da Lubnor/PETROBRAS: estudo de caso / Management and characterization os solid waste Lubnor/PETROBRAS: a case study
The situation of solid waste in Brazil is worrying, especially with regard to final disposal, as the increase in the wasteâs generation was not followed by a growth of infrastructure. The environmental issue, with the onset and worsening of environmental problems become more important to humans. Most of these problems is due to industrial waste origin, as m

6. Influência do lodo de ETE na massa para fabricação de cerâmica vermelha
The WTP produce many kinds of residue on your treatment stages, but the sludge is the more problematic from the final disposition point view. The actual rate of residue production deriving from technological evolution and the crescent population needs prevents the subtle equilibrium generation between consumption and recycling/reuse, creating problems of pol

7. Effect of the replacement of kaolin by kaolin residue on the production of ceramic / Estudo do efeito da substituição de caulim por resíduo de caulim na fabricação de cerâmica de revestimento
Companies involved in kaolin mining and treatment represent an important area of industrial development in Brazil, significantly contribution to the worldwide production of such mineral. As a result, large volumes of kaolin residue are constantly generated and abandoned in the environment, negatively contributing to its preservation. In this scenario, the ob

8. Influência do lodo de esgoto na nodulação e no desenvolvimento do Caupi (Vigna unguiculata "L" Walp)
The intense urban growth, production of domestic and industrial residues has been increased, mainly sewage sludge. This residue has high amount of pathogenic organisms and heavy metals. The viable alternative for this residue destination is its use in agriculture improving the chemical, physical and biological soil characteristics. Allied of the capacity of

10. Avaliação do comportamento fisico-quimico-mecanico de misturas cimento-cinza-casca de arroz por meio de corpos-de-prova cilindricos e placas prensadas
The recycling is an effective tool to minimize environmental impact that is caused by human civilization. The utilization agricultural residual for rural construction is an efficient way for retain or reduce carbon emission to the atmosphere. However, the present-day techno logy is not enough to be a satisfactory level. A part of the residue is not consumed,

11. Aproveitamento de Lodo de Estação de Tratamento de Água em Cerâmica Vermelha
The water treatment stations (WTA) have been researching solutions for the recycling of the residue generated in the water treatment process this residue is called WTA mud. Presently, the adopted solutions are the releasing of the residue into sanitary landfills or into the sewer system. The red ceramics presents an enormous potential to contribute for the s

12. DEVELOPMENT OF FLOW CHART FOR THE IMPROVEMENT OF WASTE CONSTRUCTION / DESENVOLVIMENTO DE FLUXOGRAMA PARA BENEFICIAMENTO DE RESÍDUOS DA CONSTRUÇÃO CIVIL
Any human activity is by nature generating of residues. The industrial activies are one of the great generators of residues, be solid, liquids or gaseous, which should be correctly management seeking to minimize costs and reduction of the potential generation in environmental impacts. In agreement with the law 6.938/81, that establish the National Politics o
