1. BIODIESEL SYNTHESIS FROM WASTE COOKING OIL USING A VARIETY OF WASTE MARBLE AS HETEROGENEOUS CATALYSTS
Abstract The research article is based on biodiesel synthesis by the transesterification of waste cooking oil with methanol in the presence of heterogeneous catalysts prepared from different marble. Eight samples of marble were successfully converted into potential catalysts by calcination. The thermal treatment of waste marbles at 300oC-1000oC converted the

2. An Environmentally Friendly Procedure to Obtain Flavonoids from Brazilian Citrus Waste
Currently, most food waste is used as animal feed and this process does not take advantage of the available chemical composition. A Brazilian example is the citrus fruit processing wastes (CFPW), which have begun to draw attention due to their biological importance. In order to access the main compounds of this matrix, an efficient and environmentally friend

3. Chemical waste generated in laboratories of UNICAMP management inventory and evaluattion / Residuo quimico gerado em laboratorios da UNICAMP : inventario e avaliação de seu gerenciamento
The chemical waste has emphasize among the generated waste types due, many times, to its high hazard degree. In this work an inventory of chemical waste active generated in laboratories of four UNICAMP Units was realized. It was inventoried and valuated the chemical waste generation from analysis realized in laboratories that more generate waste in Units sel

5. Valorização de resíduos industriais como fonte alternativa mineral : composições cerâmicas e cimentíceas
This present work describes studies of valorization of wastes as alternative raw materials. Different industrial wastes, based on the SiO2-Al2O3-CaO system and classified as non-hazardous, were selected: Al-rich anodizing sludge, sludge from the filtration/clarification of potable water, sludge generated in ornamental stone-cutting processes, and foundry san

6. Manejo de resíduos de laboratórios químicos em universidades - estudo de caso do departamento de química da UFSCar.
The universities have a basic role in a formation of a citizen, in other words, they are centers of science, technology and knowledge that affect all the society. However, the universities, through their activities of research, learning and extension, ending up by generating wastes potentially hazardous, such as the chemical laboratories. However they cannot

7. Pharmacological activity from extracts obtained of lumber residue / Atividade farmacologica de extratos obtidos a partir de residuos madereiros
The knowledge about the use of medicinal plants is, innumerable times, the only therapeutic resource for several communities; and to search new bioactive compounds from Brazilian biodiversity is one strategy with positive economic and social consequences. Additionally, part of the tropical forest is explored for lumber and wood based products, generating ann

8. Biosintese da biotina a partir de residuos da batata
The presence of biotin in lakes, rivers and sea and the difficulty in obtaining biologically active biotin by chemical synthesis motivated the search for new methods of synthesis. At present biotin can be obtained by fermentation with Esporoboromyces. In this bibliographic investigation the possibility of production of biotin in facultative lagoons receiving

9. Biodegradation of 1,2,3-Trichloropropane through Directed Evolution and Heterologous Expression of a Haloalkane Dehalogenase Gene
Using a combined strategy of random mutagenesis of haloalkane dehalogenase and genetic engineering of a chloropropanol-utilizing bacterium, we constructed an organism that is capable of growth on 1,2,3-trichloropropane (TCP). This highly toxic and recalcitrant compound is a waste product generated from the manufacture of the industrial chemical epichlorohydr
