1. Selecting chemicals for separation of ABS and HIPS in WEEE by froth flotation
Abstract The feasibility of using common chemicals to separate plastics from waste electrical and electronic equipment (WEEE) by froth flotation is investigated. Plastic waste is one of the WEEE polluters and a separation is necessary to recycle it. The most common plastics in electronic industries are acrylonitrile-butadiene-styrene (ABS) and high impact po

2. 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

3. 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

4. IONIZING RADIATION EFFECT STUDY BY ELECTRON BEAM ON ULTRA HIGH MOLECULAR WEIGHT POLYETHYLENE VIRGIN AND RECYCLED INDUSTRIAL / "Estudo do efeito da radiação ionizante por feixe de elétrons sobre o polietileno de ultra alto peso molecular virgem e reciclado industrial"
Ultra High Molecular Weight Polyethylene (UHMWPE) is an engineering plastic which has several applications, chiefly, in specific areas of the industry and medicine. UHMWPE can be even for other applications such as: port fenders, current guide, bucket coating, silos and gutters, plugs, pulleys and surgical prosthesis. This range of applications is due to the

5. DIAGNÓSTICO DO CANAL DE DISTRIBUIÇÃO REVERSO NA RECICLAGEM DOS RESÍDUOS PLÁSTICOS: POLIESTIRENO E POLIETILENO TEREFTALATO / DIAGNOSIS OF THE REVERSE DISTRIBUTION CHANNEL IN RECYCLE OF PLASTICS RESIDUES: POLYSTYRENE AND POLYETHYLENE TEREPHTHALATE
O acelerado desenvolvimento tecnológico tem provocado uma obsolescência precoce dos produtos. Com o aumento dos produtos com vida útil cada vez menor, cresce o número de resíduos gerados e chega-se ao esgotamento da capacidade dos sistemas tradicionais de disposição de resíduos. Com isso, alternativas são estudadas para a destinação final dos bens

6. Estudo da reprocessabilidade do polietileno de baixa densidade
During the last 30 years, plastics have played an important role in the lifestyle of the society and many benefits in the quality of life can be attributed to then. But with the environmental issue associated with its application, it becomes priority for the society to study the recycle of those materials. In this work, the objective was to process several t

7. Reforma catalitica do n-octano visando a produção de aromaticos
Catalytic Refonning is a process of great interest to the petrochemical industry for the production of aromatic compounds that are raw material to the manufacture of plastics, elastomers and resins. The catalytic refonning reaction of n-octane was studied in a Berty type reactor with internal recycle aiming on the maximization of xylenes and ethylbenzene. A
