1. Composites based on low-density polyethylene combined with PETcoated SBS paperboard shavings
ABSTRACT In this study, polymer composites comprised of shavings of SBS paperboard coated with polyethylene terephthalate (PET) and recycled low-density polyethylene (LDPE) were obtained. The tensile properties, flexural strength, impact resistance and water absorption were determined according to the standards published by the American Society for Testing a

2. Compatibilization of recycled polypropylene and recycled poly (ethylene terephthalate) blends with SEBS-g-MA
Abstract The compatibilization of recycled PP/PET blend with high and low concentration (20 and 5 phr) of elastomer functionalized by maleic anhydride (SEBS-g-MA) was achieved. Recycled polypropylene from plastic industry and recycled PET from post-consumer bottles was used. PP/PET blends: 80:20 w/w, 50:50 w/w and 20:80 w/w were prepared in an internal mixe

3. Recycling assessment of multilayer flexible packaging films using design of experiments
AbstractThe viability of recycling post-industrial packaging waste, compounded from multilayer laminated PET-PE films, for production of polymer blends with good physico-mechanical performance is analyzed. Initially, several PET-PE model-blends were prepared from fresh polymers and were compounded with different formulations, based on design of experiments (

4. Mechanical properties of recycled PET fibers in concrete
Fiber-reinforced concrete represents the current tendency to apply more efficient crack-resistant concrete. For instance, polyethylene terephthalate (PET) is a polyester polymer obtained from recyclable bottles; it has been widely used to produce fibers to obtain cement-based products with improved properties. Therefore, this paper reports on an experimental

5. Alternativas para o Reaproveitamento de Rejeitos Industriais de Poli(tereftalato de etileno) Reciclado / Alternatives for recycling of industrial wastes of recycled poly (ethylene terephthalate)
The production of nonwoven fabrics (NWF) by extrusion process from recycled poly(ethylene terephthalate) (PET) is an interesting way for polymer recycling used by industry which to allow conciliate economic viability with environmental benefits. However, during extrusion step, a fraction of material is lost due to equipment clogging or others factors, leadin

6. Fracture mechanics of polymer mortar made with recycled raw materials
The aim of this work is to show that industrial residues could be used in construction applications so that production costs as well as environmental protection can be improved. The fracture properties of polymer mortar manufactured with recycled materials are investigated to evaluate the materials behaviour to crack propagation. The residues used in this wo

7. Methodology to detect the presence of recyled PET in PET food package / Metodologia para detectar a presença do PET reciclado em embalagens PET para alimentos
Recently, Brazil recorded mechanical recycling of the poly (ethylene terepththalate), PET, the highest in the world, corresponding to about 53 wt %. This success in the recycling industry is due to the wide range of its applications, from textiles to packaging for the food industry. The recycled food-grade packaging could be mixed with virgin resin and repro

8. Evaluation of the feasibility of reintegrating post-consumer PET into production / Avaliação da viabilidade de reintegração de resíduos de PET pós-consumo ao meio produtivo
Entre os materiais presentes nos resíduos sólidos domiciliares, os resíduos poliméricos pósconsumo representam cerca de 27% do volume total da coleta convencional, segundo Matos (2006), com o agravante da degradação lenta, comprometendo a vida útil dos aterros sanitários e poluindo o meio urbano. Dos resíduos poliméricos, destaca-se o Poli (tereft

9. Processamento de compósitos de poli (tereftalato de etileno) reciclado reforçado com fibras de vidro
In this work, flake and post-condensed PET composites of different glass fiber contents (0, 20, 30 and 40%) were prepared. Tow kinds of fibers were employed: one fiber having an amino silane-based surface treatment and another one having an epoxi silane-based surface treatment. The composites were extruded in a single-screw extruder with a barrier double-fli
