14. Influence of SEBS-MA and SBS compatibilizers on properties and morphology of blends of polystyrene/rubber residue (SBRr) from the footwear industry
Abstract The reuse of rubber waste is very important today, both to reduce the harmful effects on the environment, and to reduce the cost of new material development. Considering that most of the studies reported in literature refer to the reuse of tire waste, this article aims to evaluate the influence of styrene-butadiene-styrene (SBS) and styrene-(ethylen

15. CURRENT-VOLTAGE CURVES FOR TREATING EFFLUENT CONTAINING HEDP: DETERMINATION OF THE LIMITING CURRENT
Abstract Membrane separation techniques have been explored for treating industrial effluents to allow water reuse and component recovery. In an electrodialysis system, concentration polarization causes undesirable alterations in the ionic transportation mechanism. The graphic construction of the current voltage curve is proposed for establishing the value of

16. The Recycling of Sugarcane Fiber/Polypropylene Composites
Mechanical recycling is utilized to reuse waste and obtain other plastic products via the reprocessing of a material in industrial equipment. Natural fiber composites have become more popular in recent years; however, these composites' mechanical behavior remains less well-understood than single polymers’ behavior after recycling. Therefore, the objective

18. Projeto industrial para aeração automática de leiras de compostagem orgânica / Industrial project for automated aeretion of organic composting piles
Composting is a safety environmental alternative to reuse and treat organic wastes produced by human-beings. Although decomposition naturally happens, the handling of some factors, such as oxygen level, temperature, moisture content and pH, can alter the process speed, accelerating microbial activity. Aeration is a crucial practice during the composting proc

19. 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

20. A web service application to support distributed manufacturing
Manufacturing as an industrial activity that starts with the conceptual project and ends with proper material disposal or its reuse has evolved from a centralized to a distributed process. The several components of the process are distributed according to space and time. This evolution was possible due to the support of information technology, which allows m

21. Tratamento da água de purificação do biodiesel utilizando eletrofloculação
Biodiesel was created as a solution for a great economic and enviromental problem of petroleum, a resource with sustainable characteristics. But its production still needs optimization, because it uses a lot of water and generates a large volume of this residue, which appears improper to disposal without correct treatment. This work propose an economic, viab

22. Elaboración de recubrimientos cerámicos mediante proyección térmica por combustión a partir de residuos sólidos industriales
Ceramic coatings were elaborated onto carbon steel substrates by oxy-fuel thermal spraying process from catalysts waste used in petroleum refining. The adhesion and micro-hardness Vickers were evaluated according to ASTM C633-01(2008) and ASTM C1327-08 standards respectively, with adhesion values varying between 2,9 and 17,7 MPa and values of microhardness V

23. Aproveitamento de membranas de osmose inversa descartadas da indústria para o reuso da purga de torres de resfriamento
Reverse osmosis plants use new membranes to produce demineralized water. After a period of three to five years, the membranes are replaced by news ones due to levels of treatment which are not suitable for production of water with the desired characteristics. This process generates a lot of rejected modules causing an environmental problem. The present work

24. Reúso de água na indústria química - estudo de caso de uma unidade produtiva de nitrocelulose. / Wastewater reuse in the chemical industry - study case of a nitrocellulose unit.
O recurso água é de primordial importância para a vida, para a sociedade e para os processos industriais. A redução da disponibilidade de água, devido ao aumento de sua demanda, à poluição das bacias hidrográficas e à escassez de fontes limpas, pressionam os órgãos reguladores a elaborar leis que restrinjam seu consumo, a criar normas que contro
