Faced with the global discussion about the development of new alternative energy sources, this work tries to contribute to the understanding of the introduction of biodiesel in the energy market, identifying the barriers in the social logic, economic and productive in different spaces, rural and urban. Based on the guidelines of the National Biodiesel Production and Use Program (PNPB), it intended to accompany the implementation of public policies in relation to family farmers settled in the Pontal, located in the western region of São Paulo. In parallel, we will analyze the organizational structure and logistics of the production of biodiesel in the city, although it does not dependent on agricultural production and it is not a target of public policies, it takes advantage of the demand created by PNPB when it comes to increasing the amount of biodiesel blended with mineral origin diesel. The activity examined in the urban space is the collection of used frying oil held by Ecosanta Biofuels, a company located in the town of Maua, São Paulo metropolitan region. The monograph aims to broaden our understanding despite the urban-rural issue regarding the obstacles and opportunities in expanding renewable energy

Biodiesel is a reality in Brazil, due to the National Program of Biodiesel Production and Use (PNPB), which became mandatory in 2008 in adding 2% biodiesel in all diesel sold in a blend known as B2. The agribusiness sector responded to the federal program, facing many difficulties in biodiesel production, which highlights the supply of raw material. Problems related to biodiesel production were mainly the shortage of vegetable oil, because of demand from domestic and foreign markets, and rising prices of raw materials available for production, making this biofuel production economically feasible, even in Brazil, where agricultural production costs are among the most competitive in the world. The crambe is a specie that has aroused the interest of Brazilian producers due to oil content, hardiness, and mechanized cultivation, mainly for being a winter crop, it becomes one more option for farmers in this period. In addition, you can compose systems of crop rotation as well as being used as ground cover in winter. The aim of this study was to evaluate the potential for productive and cost of production of crambe, conducted in no-tillage system, to compare these parameters with other oil crops such as sunflower, canola and soybean. The trial was conducted in the agricultural year 2008 at the Experimental Farm Lageado belonging to the Faculty of Agronomic Sciences - UNESP, located in Botucatu - SP. The estimated yield was 1.507,05 kg ha-1, resulting in a production of 561,94 liters of oil per hectare. The cost of installation and conduct of crambe per hectare was R$ 875,87, resulting in a cost of R$ 1,56 per liter of oil, the lowest cost among the oilseed crops analyzed.

Considerando que o Brasil detém uma vasta gama de matérias-primas para produção de biodiesel, e também que há a possibilidade de produção em pequena escala, prima-se por estudos de cunho econômico a partir de metodologias de fácil execução. O objetivo do trabalho foi demonstrar uma metodologia e sua aplicação para avaliação dos custos inseridos dentro do processo produtivo e de utilização do biodiesel. A metodologia foi aplicada a biodieseis originários de óleo de soja, girassol, frango e sebo bovino, dos quais se avaliaram economicamente os custos fixos e variáveis para conversão química dos óleos e gorduras em ésteres metílicos, em uma planta de produção experimental. Os custos de produção para cada uma das quatro citadas são distintos em função do valor inicial por litro de cada uma. Também fora avaliado o custo específico e o consumo específico de cada um dos biodieseis, a fim de determinar a diferença em relação ao óleo diesel comercial. No estudo de caso, os resultados mostraram vantagens para o óleo diesel, tanto no custo quanto no consumo. Comparando-se os biodieseis, o de sebo bovino apresentou-se com o menor custo de produção e o menor consumo.

The National Neonatal Screening Program (NNSP) set up in all Brazil, aims, through planned phases of local implementation, to detect diseases such as phenylketonuria, congenital hypothyroidism, hemoglobinopathies and cystic fibrosis. The aim of this study was to assess, through a cross-sectional observational study, the prevalence of the diseases detected by the NNSP in the city of Araraquara, in records issued by the São Paulo APAE laboratory in the period between April and December 2009.The results show that Araraquara had a prevalence of phenylketonuria and congenital hypothyroidism 0.06% above the national averages of 0.01% and 0.03% respectively. With respect to hemoglobinopathies, the prevalence of sickle cell trait was 2.15% below the national average of 2.6%. The prevalence of Hb C in the city was 0.57%, similar to national values reported in the literature. Confirmed Hb Bart's had a prevalence of 0.13% in Araraquara, below the average of 0.38% for the surrounding region. The neonatal screening by heel-prick test and counseling for caregivers are important factors in reducing morbidity related to the evolution of these diseases.
