13. Efeito da composição e tamanho de partículas de resíduos de pinus nas propriedades de compósito de polipropileno / Composition and particle size effects on polypropylene composite properties
Wood pallets manufacture process at a company at Campinas region generate 100 tons per day of woodflour (Pinus sp), which are currently used for burning in industries of the region contributing to the global warming. The aim of this research was evaluated the effect of formulation and size woodflour (Pinus sp) in properties of polypropylene composite. It was

14. 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

15. 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

16. Characterization and exploitation of piston ring chips in the rectification process a new recycling proposal
The rough grind machine operation in metallic material produce a sub product with the followings components such as: metallic residue, small parts come from the resin grinds, diatomaceous earth material (filter material) and soluble oil in water for tools cooling. According [HU1UH] from ABNT, this sub product is toxic, not inert material, aggress the environ

17. Benefícios sociais e ambientais do coprocessamento de pneus inservíveis: estudo de caso na cidade de João Pessoa-PB
The useless tire is a residue that must be managed correctly until its final disposal as well as its collection and storage must be done adequately. Therefore, if it is inadequately disposed of, it can cause damages to the environment and to public health. In March 2005 the city of João Pessoa, initiated a program called Programa Nordeste Rodando Limpo - No

18. 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

19. Análise de propriedades térmicas e mecânicas de compósitos de argamassa e resíduo de borracha
Although already to exist alternative technique and economically viable for destination of used tires, quantitative data on properties of constructive elements that use the rubber waste as aggregate still are restricted. In the present work, the waste proceeding from industry of retreading as material for manufacture of composite destined to the production o

20. Enviromental diagnosis of the management and destination of the the construction &demotition waste (CDW) : analysis of the builders associatede to the SINDUSCON/RN and companies active collectors in the town and companies active / Diagnóstico ambiental da gestão e destinação dos resíduos da construção e demolição (RCD): análise das Construtoras Associadas ao SINDUSCON/RN e empresas coletoras atuantes no município de Parnamirim - RN
Surveys carried out in many Brazilian cities have shown that the CDW Construction and Demolition Waste, in some cases, represent more than 50% of the mass of urban solid residue. Municipalities have struggled to manage in an effective way huge quantities of CDW generated every day and solve the problem of the illegal dumping in an inadequate area, which comp

21. Characterization of ground SBR scraps from shoe industry
Expanded poly(butadiene-co-styrene) (SBR), a residue of the shoe industry of Rio Grande do Sul, is a crosslinked material. For further utilization in recycling and reclaiming processes this residue was ground under ambient conditions. The obtained powder (SBR-r) was physically, thermally and chemically characterized and the results were analyzed as for its s

22. 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

23. Co-pirólise de polipropileno pós-consumo com gasóleo / Co-pyrolysis of polypropylene residues with gas-oil
In this study, the process of co-pyrolysis of polypropylene (PP) residues with gas-oil was evaluated, varying the temperature and the amount of polypropylene fed to the reactor. The co-pyrolysis is a promising route to minimize the environmental impact caused by the inadequate disposal of plastics, preventing its accumulation in landfields and giving a bette
