1. Diesel-Like Biofuels Production Using Fatty Waste
According to the waste-to-energy (WTE) valorization and circular economy principles, the use of waste oil and grease (WOG) for obtaining biofuels shows the tendency towards sustainability, makes the interest in green chemistry, and the development of environmentally friendly processes grow. Three different fatty wastes (from the fat trap of a sewage station,

2. THE SUCCESS OF THE BRAZILIAN ALCOHOL PROGRAM (PROÁLCOOL) - A DECADE-BY-DECADE BRIEF HISTORY OF ETHANOL IN BRAZIL
ABSTRACT The National Alcohol Program (Proálcool) was a strategic policy of the Brazilian government to replace petroleum-based fuels with alcohol (ethanol). Based on the review, we can choose the 1960s as a start point for a leap in development. Over the 500 years of sugarcane history in Brazil, the crop enters the second decade of the 21st century with ex

3. Microstructural, thermochemistry and mechanical evaluation of self-reducing pellets using electric arc furnace (EAF) dust containing zinc for Waelz process
ABSTRACT The increment of recycling of steel using electric arc furnace and the tendency to coat of steel products with zinc, in order to prevent corrosion, has increased the proportion of galvanized scrap used worldwide in the recent years. Approximately 10 to 20 Kg/t of cast steel is generated in casting arcs. These collected dusts electric arc furnace (EA

4. L-(+)-Lactic acid production by Lactobacillus rhamnosus B103 from dairy industry waste
ABSTRACT Lactic acid, which can be obtained through fermentation, is an interesting compound because it can be utilized in different fields, such as in the food, pharmaceutical and chemical industries as a bio-based molecule for bio-refinery. In addition, lactic acid has recently gained more interest due to the possibility of manufacturing poly(lactic acid),

5. Avaliação técnica e econômica para aproveitamento da biomassa caprina em biodigestores no Semi-Árido Baiano.
The exhaustion of some fossil energy sources, caused by the increasing demand in the last years, as well as the worldwide consciousness about the environment issues, has brought a continuous quest for new sustainable means of production. In this new context, the biogas technology represents a real possibility of generating clean energy and, at the same time,

6. Estudo da influência de pré-tratamentos de dois resíduos lignocelulósicos (bagaço do pedúnculo de caju e casca de coco) utilizados como substrato na indução à síntese de enzimas celulolíticas
Nowadays generation ethanol second, that t is obtained from fermentation of sugars of hydrolyses of cellulose, is gaining attention worldwide as a viable alternative to petroleum mainly for being a renewable resource. The increase of first generation ethanol production i.e. that obtained from sugar-cane molasses could lead to a reduction of lands sustainable

7. Biodegradação de polietileno tereftalato (PET) por fungos ligninoliticos / Biodegradation of polyethylene tereftalate by ligninolytic fungi
In 1977, polyethylene terephthalate (PET), a plastic derived from petroleum, started to be used as raw material for packaging material and engineering plastics. However, under an environmental point of view, the use of plastics is considered problematic because of their high durability and high volume when present in domestic and industrial solid wastes. Thi

8. Avaliação da remoção de sulfeto de hidrogênio do gás natural em uma coluna de absorção
Natural gas, although basically composed by light hydrocarbons, also presents in its composition gaseous contaminants such as CO2 (carbon dioxide) and H2S (hydrogen sulfide). Hydrogen sulfide, which commonly occurs in oil and gas exploration and production activities, besides being among the gases that are responsible by the acid rain and greenhouse effect,

9. Estudo de reatores eletroquímicos para remoção de Cu2+ , Zn2+, Fenol e BTEX em água produzida
The production of water has become one of the most important wastes in the petroleum industry, specifically in the up stream segment. The treatment of this kind of effluents is complex and normally requires high costs. In this context, the electrochemical treatment emerges as an alternative methodology for treating the wastewaters. It employs electrochemical

10. Rhizospheric microorganisms and arbuscular mycorrhiza in soil from a petrochemical waste landfarming system. / Microbiota RizosfÃrica e Micorriza Arbuscular em Solo de "Landfarming" de ResÃduos PetroquÃmicos.
In the petroleum industrialization a great volume of different toxic residues is generated. Because of these waste environmental hazards they need to be adequately treated before final disposition in the environment. These wastes are usually treated by landfarming systems, but this technique has only relative success, since it doesn t completely remove all c

Hydric balance in the Paulinia s refinery and alternatives for water reuse : establishment of an auxiliary tool for the hydric resources management / Balanço hidrico na refinaria de Paulinia e alternativas para reuso de agua : construção de uma ferramenta auxiliar para o gerenciamento dos recursos hidricos
In the last years the shortage of water has been theme of discussions not only in scientific works but also in politics, media and civil society areas, due to the consciousness-raising to this problem worldwide. In Brazil, the metropolitan area of Campinas is among the ones that experience more deeply this kind of problem (DEA = 278.9 3m/year.inhabitant), wh
