1. Manufacturing and characterization of sustainable macroporous glass foams
Abstract This work produced glass foams from soda-lime glass bottles, bentonite, and alumina by the replica method. Compositions with different contents of bentonite (5, 10, 15, and 20 wt%) were prepared and heat-treated at 800 °C. In the alumina-added compositions, 50 wt% of the bentonite was replaced by the alumina. The influences of the content of benton

2. Avaliação da energia incorporada e da emissão de CO2 em recipientes para refrigerantes: PET versus vidro
RESUMO Este artigo busca avaliar e comparar qual material (PET ou vidro) proporciona um ciclo de vida mais sustentável para os recipientes utilizados no envase de refrigerantes. Foram comparados quatro recipientes de vidro - três retornáveis e um descartável - com cinco recipientes em polietileno tereftalato (PET) - três descartáveis produzidos com mat

4. Desenvolvimento de espumas vítreas a partir de garrafa e casca de ovo
RESUMO Este trabalho tem como foco a produção de espumas vítreas a partir de materiais reciclados, fazendo uso de matéria-prima de fácil acesso local e alta incidência no mercado: garrafas de cerveja não retornáveis e casca de ovo, como agente espumante. Para tanto, investigou-se a influência da temperatura de queima, da granulometria do vidro precu

5. Preservation and evaluation of spiced chayote juice using hurdle technology
Resumo Chuchu (Sechium edule) é uma trepadeira perene da família das Cucurbitaceae que está ignorada ou subutilizada como alimento ou como uma matéria-prima na indústria de alimentos, devido ao seu gosto brando. Este gosto brando pode ser superado fazendo misturas com um substrato apropriado, como caldo de cana e algum flavorizante natural. Contudo, est

6. 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

7. 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

8. Comportamiento del residuo de vidrio molido en cementos mezcla: Estudio comparativo con microsilice
ABSTRACT Due their high content of silica in an amorphous state the glass, in theory, can behave as pozzolanic material when are finely ground. This opens up an interesting way of reusing these materials in the Portland cement industry (CP), especially considering that solid urban waste (RSU) in Argentina contains between 3 and 5% by weight of glass. This pa

9. 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

10. 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

11. ATUAÇÃO DE BENTONITE E POLIVINILPOLIPIRROLIDONA (PVPP) NA CLARIFICAÇÃO DE VINHOS ESPUMANTES / PERFORMANCE OF BENTONITE AND POLYVINYLPOLYPYRROLIDONE (PVPP) IN THE CLARIFICATION OF SPARKLING WINE
The size and persistence of the bubbles is one of the characteristics pursued by consumers of sparkling wine. The perlage is closely linked to nitrogen products, usually proteins of low molecular weight. Furthermore, bentonite and polyvinylpolypyrrolidone (PVPP) are glues used both in cleaning up the base wine and the sparkling wines, in other words, the fer

12. Culicídeos associados a bovinos de leite, no sul do Rio Grande do Sul, Brasil
The occurrence of mosquitoes in the authoring environment of dairy cattle was verified in southern Rio Grande do Sul. For collection of specimens, it was installed a Magoon trap, in which during a couple of cattle-approximately six months of age was placed. Samples were collected during 24 hours, twice a month for 12 months. After 24 hours, the cattle were r
