O presente Manual de Boas Práticas Portuárias – Porto de Aratu-Candeias é resultado da iniciativa interinstitucional da Secretaria de Portos da Presidência da Presidência da República (SEP/PR) que, em parceria com a Universidade Federal do Rio de Janeiro (UFRJ), por intermédio do Instituto Virtual Internacional de Mudanças Globais (IVIG), elaborou um Guia de Boas Práticas Portuárias, sob o pálio do Programa de Conformidade do Gerenciamento de Resíduos Sólidos e Efluentes Líquidos nos Portos Marítimos Brasileiros, desenvolvido no âmbito do PAC II (Programa de Aceleração do Crescimento – Fase II), cujo objetivo é o estabelecimento de diretrizes sustentáveis para o setor portuário no país.

This study aims to calculate indicators and indexes to subsidize the analysis of vulnerability and adaptation of the renewable energy sector to climate change in Brazil, focusing on biofuels and solar energy. For biofuels, in general, the Brazilian coast will be a propitious area for agricultural productivity during the XXI century, but these are areas historically intended for occupation and development of the urbanization process, that is, with limited land availability and supply for primary production. In some parts of the Northeast, Midwest and South of the country, offer for the cultivation land will be reduced. For the solar energy is observed that Brazil has area and highly expressive power for the use of this power, both today and in the coming decades, especially in the North, Northeast and Midwest. In statistical terms, the Mann-Kendal test and Sen’s Bend point to a very weak tendency to useful radiation indicator in all regions of Brazil by 2100. In addition, it is projected a significant increase in mean air temperature by the end of XXI century across the country that can mean a reduction in power conversion capability, which is sensitive to ambient temperature variations, especially in the Midwest and North of the country.

The use of the extraordinary hydroelectric potential of the Amazon Basin originated an increase in the offer of renewable energy in Brazil, which, in its turn, leads to conflicts and a lack of consensus among different players owing to the potential negative impacts related to the construction and operation of large hydroelectric power plants in relatively well preserved areas. In this context, environmental licensing is one of the national environmental policy’s main instruments for making decisions regarding the use of the hydroelectric potential, especially the rivers of the Amazon Basin. Nevertheless, this significant instrument has its limitations and requires adjustments in order to better aid the decision making process regarding the use of water resources and land with the goal of increasing the offer of electric energy.

The use of Urban Solid Waste (USW) as sources of energy has acquired rising importance in current discussions of alternative energy supplies, in particular in Brazil. This paper brings to these discussions an examination of the concept of solid wastes, including their historic origins and formation, taking their social, economic and cultural characteristics into account, including point view of waste production liturgy. Consequently, a spendthrift society slanted towards the decreasing marginal utility of assets must make efficient use of its USW in order to reduce excessive output. Besides that, this document presents the Brazilian potential of urban solid waste to produce electric power.

The purpose of this article is to evaluate the performance, in terms of specific consumption in g/kWh, of biodiesel produced from soybean oil, palm oil and residual frying oil, by means of ethylic and methylic routes, in blending percentages of 20% and 50%, at different power levels, for electric power generation from stationary internal combustion engines. The results are evaluated by Tukey′s range test, which enables the comparison of any and all contrasts between two averages of a variable. The results evidence that the 20% blend of biodiesel from soybean oil produced by methylic route seems to be the one whose performance is the closest to the reference fuel′s, and that the proportion of biodiesel has affected more significantly the performance of the blend tested than the type of raw material or route, in relation to the specific consumption for all power levels.

The new frontier for hydropower electricity generation in Brazil, the Amazon region, cannot be used for energy storage as the construction of storage reservoirs would have deep environmental and social impacts, thus run-of-the-river dams have been built instead. If Brazil still wants to generate 80% of its electricity from hydropower, there is the need to increase the country’s energy storage capacity so that the excess generation coming from the dams in the Amazon region during the wet period can be used during the dry period. This article presents four ways to increase the storage capacity of a watershed. The most innovative alternative involves a large-scale pumped-storage site combined with a series of hydropower dams in cascade, which could store energy by pumping water to a new reservoir during the wet period and generate energy by releasing the stored water during the dry period. Even though pumped storage schemes have an average efficiency of around 75%, it has been calculated that the combination of a pumped storage site and a series of hydroelectric dams in cascade can increase the overall storage efficiency up to 90% and double the storage capacity of a watershed. This scheme was called EPS (Enhanced-Pumped-Storage).
