14. Plastic packing final destination / A reciclagem das embalagens plásticas de óleo lubrificante e a gestão ambiental: um modelo a ser construído
The final destination, after use, of plastic packaging with motor oil residues is one problem worldwide. The polymer resistance to biodegradability and the residual oil contamination represents a great environmental risk. The final destination of plastic packaging is an ethical and legal claim in the comp anies. This work presents a review of a waste managem

15. 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

16. Desenvolvimento de blocos confeccionados com escória proveniente da reciclagem do aço / Development of blocks made with slag from steel recycling
This reasearch aims at evaluating the use of slag from steel making in the production of self-supported blocks for masonry. The largest residual volume generated from the steel making process is the slag, which is used for cement production and paving of roads. There is a lot of researches and papers issued about such subjects. However, the use of slag to ma

17. 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

18. Influência da substituição do agregado miúdo natural por agregado reciclado fino em propriedades de argamassas e concretos
Construction and demolition waste (CDW) recycling has been a good alternative to reducing the impact caused by the consumption and high demand of raw materials for civil construction. In this sense, it has been tried to incorporate those wastes in the production of concrete and decrease strength mortar, what would increase its potential use. This study was d

19. Characterization of the urban solid residues of the Maceió-AL city. / Caracterização dos resíduos sólidos urbanos da cidade de Maceió-AL.
This work presents and argues the characterization of the urban solid residues generated in Maceió-AL, by means of laboratory and field assays, searching to contribute for operational improvements in the system of urban cleanness of the city. The residues had been collected monthly from routes previously defined, in the period of one year, in eight differen

20. Treatment of industry wastewater from a plastic containers (containing originally lubricant oil) recycling industry : biological and physical-chemical process / Tratamento de efluentes de uma industria de reciclagem de embalagens plasticas de oleos lubrificantes : processo biologico e fisico-quimico
In the present work, the treatment of the wastewater originated in a plastic container (containing originally lubricant oil) recycling industry was investigated. The purpose of this work was to study the individual efficiency to treat the industrial effluent, mixture of the plastic container washing process wastewater and sanitary wastewater, by activated sl

21. Reuso de agua em industria de reciclagem de embalagens plasticas : aspectos economicos e ambientais em modelo de escala real / Water reuse on plastics recycling pack industry : economical and enviromental aspects in real scale model
The discussion about technical, economical and environmental feasibility of water reuse in industrial process has been a constant concern. This thesis purposes a simplified alternative for waste water treatment seeking reuse in a plastic recycle industry. The water, in this case, is a prime component because it is the main element for the debris and impuriti

22. Development and evaluation of a biosafe automatized system for treatment, recycling and discarding of clinical microbiology residues / Desenvolvimento e avaliação de um sistema automatizado biosseguro para o tratamento, reciclagem e descarte de resíduo de microbiologia clínica
In Brazil, daily, 2.3 tons of potentially contaminated cultured medium with microorganisms are discarded. The RDC 306 resolution from the Brazilian National Health Department rules out that residue must be treated prior to discart in order to reduce microbial load. Two methods were developed to evaluate the sensitivity, efficiency and ideal concentration of

23. SÃntese e caracterizaÃÃo de membranas de acetato de celulose, obtido do bagaÃo de cana-de-aÃÃcar, e blendas de acetato de celulose com poliestireno de copos plÃsticos descartados
In the present dissertation, the synthesis and characterization of cellulose acetate membranes as well as cellulose acetate and polystyrene blends, were studied. Recycled materials were used to produce the blends. Cellulose acetate (CA) was produced from sugarcane bagasse, and waste plastic cups were used as polystyrene (PS) source. Blends, produced with dif

24. Effluent treatment from recycling plastics industry, using a anaerobic compartmented and cultivable bed / Tratamento de efluente de industria recicladora de plasticos utilizando reator anaerobio compartimentado e leitos cultivados
Os plásticos fazem parte dos resíduos sólidos urbanos, que devido ao grande volume gerado, tem causado entre outros fatores, impactos ambientais e redução da vida útil dos aterros. Uma das propostas básicas apresentada pela Agenda 21 para gerenciamento dos resíduos sólidos, é a reciclagem dos materiais, que apresenta importantes benefícios, como r
