The Brazilian relief, predominantly composed by small mountains and plateaus, contributed to formation of rivers with high amount of falls. With exception to North-eastern Brazil, the climate of this country are rainy, which contributes to maintain water flows high. These elements are essential to a high hydroelectric potential, contributing to the choice of hydroelectric power plants as the main technology of electricity generation in Brazil. Though this is a renewable source, whose utilized resource is free, dams must to be established which generates a high environmental and social impact. The objective of this study is to evaluate the impact caused by these dams through the use of environmental indexes. These indexes are ratio formed by installed power with dam area of a hydro power plant, and ratio formed by firm power with this dam area. In this study, the greatest media values were found in South, Southeast, and Northeast regions respectively, and the smallest media values were found in North and Mid-West regions, respectively. The greatest encountered media indexes were also found in dams established in the 1950s. In the last six decades, the smallest indexes were registered by darns established in the 1980s. These indexes could be utilized as important instruments for environmental impact assessments, and could enable a dam to be established that depletes an ecosystem as less as possible.

Replacing glass fibers with natural fibers in the automobile industry can yield economic, environmental and social benefits. This article evaluates the prospective environmental impacts of automobile applications of curauá fiber (Ananas erectifolius), which nearly equates the physical properties of glass fibers. The study identified economic and social advantages of applying curauá fiber composites in car parts. Besides costing 50% less than fiber glass, the use of curauá fibers can promote regional development in the Amazon region. In order to realize significant environmental benefits, however, the curauá-based composites would have to be lighter than their glass fiber-based counterparts. © 2006 Elsevier Ltd.

The lack of proposals to evaluate the greening of business incubators or even of elementary discussions about the relations between incubators and the environment becomes apparent when researching this topic in the most prestigious scientific sources. To address this gap, this article reviews the literature on green management and smaller enterprises, business incubator performance and the greening of business incubators. This conceptual big-picture was used to identify variables relevant to the construction of a framework for assessing business incubators green performance. This framework was applied to six business incubators in Brazil. The results show the appropriated applicability of this framework. Furthermore, the empirical research led to the formulation of environmental maturity levels in order to classify business incubators performance. This paper seeks to offer a starting point for discussion and a proposal regarding the role of business incubators in a more sustainable society. © 2011 Elsevier Ltd. All rights reserved.

The marine environment offers both economic and scientific potential which are relatively untapped from a biotechnological point of view. These environments whilst harsh are ironically fragile and dependent on a harmonious life form balance. Exploitation of natural resources by exhaustive wild harvesting has obvious negative environmental consequences. From a European industry perspective marine organisms are a largely underutilised resource. This is not due to lack of interest but due to a lack of choice the industry faces for cost competitive, sustainable and environmentally conscientious product alternatives. Knowledge of the biotechnological potential of marine organisms together with the development of sustainable systems for their cultivation, processing and utilisation are essential. In 2010, the European Commission recognised this need and funded a collaborative RTD/SME project under the Framework 7-Knowledge Based Bio-Economy (KBBE) Theme 2 Programme 'Sustainable culture of marine microorganisms, algae and/or invertebrates for high value added products'. The scope of that project entitled 'Sustainable Production of Biologically Active Molecules of Marine Based Origin' (BAMMBO) is outlined. Although the Union is a global leader in many technologies, it faces increasing competition from traditional rivals and emerging economies alike and must therefore improve its innovation performance. For this reason innovation is placed at the heart of a European Horizon 2020 Strategy wherein the challenge is to connect economic performance to eco performance. This article provides a synopsis of the research activities of the BAMMBO project as they fit within the wider scope of sustainable environmentally conscientious marine resource exploitation for high-value biomolecules. © 2013 Elsevier B.V.

This special volume of the Journal of Cleaner Production is comprised of articles presented at the 3rd International Workshop Advances in Cleaner Production held in Sao Paulo, Brazil, in 2011. The content underscores the recognition of the pressing and inescapable need for making changes from unsustainable to sustainable production and consumption patterns. The 48 articles from 15 countries provide different, but complimentary approaches to help industrial and societal sectors in advancing on their paths towards sustainability. Initiatives and challenges are included, which systematically address problems affecting raw material changes, technological modifications, product and policy changes. The findings range from proposals for alternative uses of wastes, substitution of raw materials for environmentally friendlier substances, optimization of industrial processes by source reductions of wastes and emissions and documented economic and environmental advantages of a wide array of initiatives. The roles of operational and managerial practices are also stressed, highlighting the role of diverse stakeholders as promoters of implementation and internalization of innovative cleaner technologies within companies. Systemic assessment tools are employed and experimented with in order to more effectively evaluate the environmental performance of systems on the biosphere scale. The methodological procedures and proposals presented can help in the design and management of production systems, for governmental and corporate policy development, for implementing and monitoring CP Programs, prevention and mitigation strategies, and evaluation of the outcomes of CP initiatives in the production and service sectors.

This study analyzes the environmental performance of the Municipal Solid Waste Management System (MSWMS) of Piedade, São Paulo, from a systemic perspective. A life cycle assessment (LCA) technique was applied according to an attributional approach to evaluate both the current operational situation and different prospective scenarios, which were devised based on the application of targets for recycling dry and wet waste suggested by the pre-draft version of the Brazilian Plan for Solid Waste. The life cycle impact assessment method EcoIndicator 99, in association with normalization and weighting procedures, was used to conduct the analysis. It was observed that the adoption of goals of 30%, 50% and 70% for recovering of the recyclable dry waste, resulted in improvement of the environmental performance of the waste management system under analysis, respectively of 10%, 15% and 20%. It was also possible to detect an evolution in the order of 54% in reducing impacts resulting from the adoption of targets for composting. LCA proved to be effective for the evaluation of the environmental performance of MSWMS-Piedade. However, for future evaluations, the attributional approach should be replaced by the methodological practice of substitution to enable the avoided burdens to be considered in estimations of the environmental performance municipal solid waste management systems.
