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. Influence of lubricant oil residual fraction on recycled high density polyethylene properties and plastic packaging reverse logistics proposal
Abstract To recycle post-consumer HDPE contaminated with waste lubricating oils, companies include prior washing and drying in the process. This consumes large amounts of water and energy, generates significant effluent requiring treatment. This study assesses lubricating oil influence on HDPE properties to evaluate the feasibility of its direct mechanical r

3. Reciclagem do lixo de informática: uma oportunidade para a química
Recycling and sustainable development are increasing in importance around the world. In Brazil, the new National Policy on Solid Wastes has prompted discussion on the future of electronic waste (e-waste). Brazil generates the greatest amount of e-waste among Latin American countries. Nevertheless complete recycling, including end processing of e-waste, does

4. 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

5. 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

6. 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

7. Reciclagem de fios e cabos elétricos. / Recycling of wires and eletrical cables.
The electro-electronics industry follows increasing the amount of scraps annually generated. For this reason it is necessary to recycle, so that it prevents the waste of raw materials and not renovable natural resources. The majority of the electro-electronic products do not receive any treatment after use and is disposed in municipal landfills together with

9. 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
