1. Sustainable Glass Foams Produced from Glass Bottles and Tobacco Residue
In this work, discarded soda-lime-silica glass bottles and tobacco residue (after oil extraction to produce biodiesel) were prepared in different formulations to obtain glass foams. The formulated compositions were homogenized and uniaxially compacted at 40 MPa then fired at 850 ºC and 900 ºC for 60 min to investigate the effects of tobacco residue and tem

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. Characterization of Vitrocrystalline Foams Produced from Discarded Glasses and Recycled Polystyrene Spheres
In this work, discarded soda-lime glasses (from glass bottles) and recycled polystyrene (PS) spheres (d50 < 300 µm) were successfully converted into vitrocrystalline foams for thermal insulation applications. Physical and chemical properties of the selected and prepared raw materials (wastes) were characterized. Batches containing well mixed glass powder (d

4. Thermal Insulating Foams Produced From Glass Waste and Banana Leaves
Abstract In this work, compositions containing transparent glass bottles and banana leaves (desiccated and crushed), with different mass fractions (30-50%), were prepared for obtaining cellular materials for thermal insulation purposes. The formulated and prepared compositions were uniaxially pressed (10 MPa) and the compact powders fired between 700 and 850

5. Blocos para execução de alvenaria de vedação empregando garrafas pet: avaliação mecânica e termoacústica
Recycling and reuse of materials is the most evident solution regarding sustainable development. One relevant aspect to this development refers to the integration of engineering to devise ways that enable the reuse of materials considered as waste, but with great potential of applicability in the building industry itself, through the generation of appropriat

6. Efeitos da história térmica nas propriedades do polímero pet: um experimento para ensino de análise térmica
Polyethilenetherephtalate (PET) is commonly used in manufacturing of beverage bottles representing a didactic appeal in thermal analysis education due to its presence in the student's day life. Additionally such polymer presents well defined thermal analytical curves and a well known thermal behavior. TGA curve is used to present the thermal stability. The t

7. AnÃlise da utilizaÃÃo de gargalos e fios de garrada pet como enchimento de torres de resfriamento
In some industrial processes, as well as in air conditioning processes, there is the need for cooling of equipments that generate heat during his operation. Usually, the fluid utilized to dissipate that generated heat is the water, due to its physical characteristics (high heat capacity, low viscosity, high thermal conductivity and high density). Besides its

11. Influence of different storage temperatures on Alicyclobacillus acidoterrestris CRA 7152 survival in hot-filled orange juice. / Influencia das diferentes temperaturas de estocagem na sobrevivencia de Alicyclobacillus acidoterrestris CRA 7152 em suco de laranja tratado por enchimento a quente.
Hot-Fill thermal treatments of orange juice are not enough to eliminate Alicyclobacillus acidoterrestris due to its high thermal resistance. Therefore the microbial control of this microorganism can only occur by adequate product storage conditions. In order to evaluate the effects of the thermal conditions of storage on germination of Alicyclobacillus acido

12. UtilizaÃÃo de materiais alternativos como Enchimento de Torres de Resfriamento
This work studies the behavior of alternative materials as packing for cooling towers. The following materials had been evaluated: vegetal sponge ( Luffa Cylindrica), coconut ( Cocos nucifera Linnaeus) fiber, curlers for hair and necks of PET bottles. In order to investigate the performance of those materials, a prototype of a cooling tower with forced circu
