Book excerpt: Dentre as principais tecnologias utilizadas na produção de mudas, destacam-se o tipo de substrato e o volume de recipiente. Atualmente o uso de residuos na formulação de substratos constitui-se uma das formas de reaproveitamento desses materiais. O objetivo desse trabalho foi testar onze substratos e dois tipos de recipientes na produção de mudas de Tagetes patula, Vinca e Pimenta ornamental. Os substratos foram formulados com composto de resíduos de CEASA + esterco bovino (composto 01), resíduos de CEASA + cama de frango (composto 02), bagaço de cana-de-açúcar + esterco bovino (composto 03), bagaço de cana-de-açúcar + cama de frango (composto 04), pó da casca de coco verde e bagana de carnaúba. O experimento foi conduzido em casa de vegetação e os substratos testados foram: SI: composto 01 + pó de coco verde + bagana (1:1 :1; v/v); S2: composto 01 + pó de coco verde (1:2; v/v); S3: composto 01 + bagana de camaúba (1:2; v/v); S4: composto 02 + pó de coco verde + bagana (1:1:1; v/v); S5: composto 02 + pó de coco verde (1:2; v/v); S6: composto 02 + bagana de carnaúba (1 :2; v/v); S7: composto 03 + pó de coco verde (1:1; v/v); S8: composto 03 + bagana de camaúba (1:1; v/v); S9: composto 04 + pó de coco verde (1:1; v/v); SIO:composto 04 + bagana de camaúba (1:1; v/v) e SI 1: substrato comercial. Os recipientes testados foram bandejas plásticas com 162 (30mI/célula) e 200 células (18mI/célula) respectivamente. Em geral, os melhores resultados dentre as culturas estudadas foram observados nos substratos formulados a base de bagana de carnaúba com qualquer um dos compostos utilizados. As bandejas com células de 18 ml produziram mudas de qualidade em Tagetes patula, ao contrário das mudas de Vinca onde se verificou os melhores resultados no volume de 30ml, e nas mudas de Pimenta ornamental não se observou influencia do volume de recipiente.

Book Synopsis Sugarcane Bioethanol by : Luís Augusto Barbosa Cortez
Download or read book Sugarcane Bioethanol written by Luís Augusto Barbosa Cortez and published by . This book was released on 2010 with total page 994 pages. Available in PDF, EPUB and Kindle. Book excerpt: In Brazil, sugarcane ethanol supplied, in 2009, 17.6 % of the energy for land transportation (excluding railroads)and about 55% of the total energy supplied by liquid fuel for Otto cycle engines. Besides the lower production costs ethanol produced from sugarcane in Brazil has another important advantage: in Central-South Brazil only 1 unit of fossil energy is used for each 8-9 units of energy produced by ethanol from sugarcane. Carbon emissions reduction also benefits from sugarcane ethanol: for each cubic meter of ethanol used as fuel, there is net saving of around 2 t CO2 not emitted to the atmosphere while, at the same time, no SO2 is emitted. Sugarcane was introduced in Brazil in 1532. The "Brazilian model" of producing concomitantly sugar and ethanol, brought important technical benefits and made possible an outstanding increase in the competitiveness in the international market for sugar and ethanol. Today about 50% of the sucrose of sugarcane produced in the country is directed to the production of sugar while another half is used to produce Ethanol. Industrial and academic R&D has helped to increase the productivity of ethanol steadily over the past 35 years, at a rate of 3.2% per year. Productivity gains implied savings of planted area by a factor of 2.6. In 2009/2010 the area planted with sugarcane for Ethanol production was 4.2 Mha, amounting to 1% of the total arable land available in Brazil. About 60% of the Ethanol produced in Brazil comes from the State of Sao Paulo, where the productivity is the highest (around 86 t/ha.year). Most of the recent expansion is happening in the center-west region of the country, in degraded pasture lands. The FAPESP Program for Research on Bioenergy, BIOEN, aims at articulating public and private R&D, using academic and industrial laboratories to advance and apply knowledge in fields related to ethanol production in Brazil. The BIOEN Program has a solid core for supporting academic exploratory research activities that will generate new knowledge and form scientists and professionals essential for advancing industry capacity in ethanol related technologies. On top of this, BIOEN includes partnerships with industry for cooperative R&D activities between industrial and academic laboratories, which are to be co-funded by FAPESP and industry.Federal agencies, such as CNPq, will also co-fund the research.

Available in PDF, EPUB and Kindle. Book excerpt: In 1992, at the United Nations Conference on Environment and Development in Rio de Janeiro, the nations of the world agreed to implement an ambitious plan for ecologically sustainable human development. This book is a comprehensive review of U.S. efforts to achieve such development since Rio. The U.S. has unquestionably begun to take steps toward sustainable development. Yet the nation is now far from being a sustainable society, and in many respects is farther away than it was in 1992. Nevertheless, legal and policy tools are available to put the U.S. on a direct path to sustainability. This book brings together 42 distinguished experts from a variety of backgrounds and academic disciplines. It is among the most thorough assessments ever conducted of U.S. law and policy concerning the environment.

Book Synopsis Industrial Uses of Biomass Energy by : Frank Rosillo-Calle
Download or read book Industrial Uses of Biomass Energy written by Frank Rosillo-Calle and published by CRC Press. This book was released on 2000-09-13 with total page 304 pages. Available in PDF, EPUB and Kindle. Book excerpt: Industrial Uses of Biomass Energy demonstrates that energy-rich vegetation, biomass, is a key renewable energy resource for the future. Brazil, uniquely, has a recent history of large-scale biomass industrial uses that makes it a specially important test-bed both for the development of biomass technology and its utilisation, and for understanding how this is shaped by political and socio-economic forces. The book analyses the cause for this and the alternatives. It is argued that Brazil's experience with the development for industrial biomass use provides wider lessons and insights in the context of the international movement for sustainable economic development. This book is an interdisciplinary, multi-author work, based upon a recently completed international study by Brazilian and British experts and will prove a valuable reference to all those working in this field.
