title: Social and environmental impacts of the Brazilian wind energy market

description: Abstract The share of wind power is rapidly increasing in the Brazilian energy market due to its large potential in some Brazilian regions and its renewability as a resource, presenting low GHG emissions compared to other energy resources. Wind energy is therefore a promising alternative given the current energy security crisis caused by more frequent water shortages. The wind power generation is presenting competitive costs with conventional energy sources. Wind farms, however, like any other economic activity, may have social and environmental impacts that must be investigated and mitigated. These controversial dimensions of wind energy make the location of wind farms a very complex problem, given the conflicting interests between local impacts and the nationwide benefit related to energy security and a cleaner energy matrix. This article presents a review of publications on wind power in Brazil in order to promote a discussion of aspects related to its social and environmental impacts. Due to the short history of wind power plants in Brazil, studies including a more-detailed assessment of socio-environmental impacts must be conducted with financial support from the energy sector itself to promote sustainable growth of wind power in the Brazilian electricity matrix.

title: Land use and its impacts on the water quality of the Cachoeirinha Invernada Watershed, Guarulhos (SP)

description: Abstract The urbanization process through which large urban centers have been passing has drastically affected the availability and especially the quality of water. The Cachoeirinha Invernada Watershed (CIW), located in the municipality of Guarulhos (State of São Paulo, Brazil), includes areas with different land use classes. This paper aims to correlate the spatial and temporal effects of land use and land cover on the water quality of the Cachoeirinha Invernada Watershed. In a period of 12 months and at six sampling points along the watershed, the physicochemical parameters temperature (T), pH, turbidity (TU), total solids (TS), electrical conductivity (EC), total phosphorus (TP), biochemical oxygen demand (BOD), as well as microbiological analysis (E. coli) were measured. Water quality was assessed using a modified version (WQIM) of the Water Quality Index (WQI) and the Trophic State Index (TSI). The areas surrounded by urban development presented a marked worsening in water quality, with the downstream point most affected and ranked as ‘POOR’. From the evaluated parameters, what contributed most to water quality degradation of the Cachoeirinha Invernada Watershed (CIW) was E. coli, followed by BOD, and TP, all parameters related to the presence of sewage in the water. The need for the construction of sewerage and waste treatment, protection and recovery of riparian forests, and environmental education regarding waste disposal are necessary to significantly improve the environmental quality of the Cachoeirinha Invernada Watershed.

title: Calculation of medium precipitation using the Thiessen method and the ridge

description: Abstract This study proposes a method to calculate hydrological areas of influence based on the Thiessen method and considering the ridge line. The study dealt with the basin of the high Sapucai, upstream of the city of Itajubá-MG, and used data from flood monitoring stations of the Federal University of Itajubá as well as images of the Shuttle Radar Topography Mission (SRTM). Through the use of this data, areas of influence were traced of rainfall stations through a combination of the Thiessen method and the lines ridges nearest mountain of these rainfall measurements. It is believed that, using results of the areas of influence of a meteorological station, this method produces results that are more accurate than other methods recommended by the specialized literature.

title: Soil map units of Minas Gerais State from the perspective of Hydrologic Groups

description: Abstract The knowledge of water availability is the basis for water resource planning and management. The Soil Map Units of the State of Minas Gerais were interpreted from the perspective of Hydrologic Groups based on the Curve Number - Soil Conservation Service method, with the addition of pedological elements of the mapped units. The generated products were used in three different physiographic environments of the Minas Gerais State. According to results, most of Minas Gerais falls within Hydrologic Groups A and B, indicating that the soils in these areas present low surface runoff and high water infiltration rates. The characterization and spatialization of the hydrological regime, with emphasis on information about the soils of Minas Gerais, as applied this study, has a level of detail not yet employed in studies of this scope, apart from the initiative to interpret them from the perspective of soil hydrological groups. The mapping of the three water resources planning and management units, composed of distinct environments, from the perspective of hydrological groups, allowed verification of the proposed methodology’s potential, which can be used to support the management and planning of the water resources of Minas Gerais. Interpretive studies of soil maps from a hydrological perspective are essential to improve our understanding of water surpluses in a given region.

title: Social and environmental innovations of Brazilian companies

description: Abstract This paper focuses on the social and environmental innovations of Brazilian companies, rather than on merely economic innovations. These innovations are discussed within the context of sustainability. Data were collected via a qualitative and descriptive study from the annual Guia Exame de Sustentabilidade magazine (2014 Edition). The magazine stated that 228 companies responded to the questionnaire. Of these, 61 companies stood out in Brazil for their policies and practices in sustainability and had their results published. The social innovations were geared towards meeting the needs of the surrounding communities. Environmental innovations appeared in greater numbers, connoting a higher stage of attention and interest from Brazilian companies. Environmental innovations were intended to evolve or improve processes and products and to reduce the consumption of resources.

title: Surface albedo in different land-use and cover types in Amazon forest region

description: Abstract Albedo is the portion of energy from the Sun that is reflected by the earth's surface, thus being an important variable that controls climate and energy processes on Earth. Surface albedo is directly related to the characteristics of the Earth’s surface materials, making it a useful parameter to evaluate the effects of original soil cover replacement due to human occupation. This study evaluated the changes in the surface albedo values due to the conversion of vegetation to other land uses and to analyze the applicability of the use of albedo in the spatial delimitation of land-use classes in the transitional region between the Cerrado and Amazon biomes. Surface albedo measurements were obtained from processing of Landsat Thematic Mapper data in the Geographic Information System (GIS), and land-use information were collected using Google Earth high-resolution images. The results show that human activities such as the cultivation of crops and burning have contributed substantially to variations in the surface albedo, and that albedo estimates from Landsat imagery have the potential to help in the recognition and delimitation of features of land use and cover.

title: Production of energy (biodiesel) and recovery of materials (biochar) from pyrolysis of urban waste sludge

description: Abstract Safe disposal of sewage sludge is one of the most pressing issues in the wastewater treatment cycle: at the European Union level, sludge production is expected to reach 13 Mt by year 2020. Sludge disposal costs may constitute up to, and sometimes above, 50% of the total cost of operation of a WWTP, and contribute to over 40% of its GHGs emissions. The most common disposal options at the moment are landfilling, disposal in agriculture (about 40% EU-wide), incineration or co-incineration, and use in the industrial production of bricks, asphalts and concrete. Sewage sludge, however, still contains beneficial resources such as nutrients, that can be recovered through specific processes (e.g. precipitation as struvite) and energy, recoverable through a variety of approaches. Microwave-assisted pyrolysis of urban waste sludge was applied for the production of oil, (Syn)gas, and biochar that were afterwards characterized and compared to mainstream alternative fuels (biodiesels) and other material recovery options. Sustainability issues related to the production of biodiesel/biochars from urban wastewater treatment sludge are also discussed. The paper shows that waste urban sludge can indeed be a full component of the urban circular economy by allowing, if properly processed, recovery of energy resources at multiple levels: bio-oils (biodiesel), syngas and bio-char, all having definite advantages for final residues use and disposal. Biodiesel, in particular, allowing energy recovery as liquid fuel, offers a much more flexible and efficient utilization.

title: Characterization of controlled landfill leachate from the city of Guaratinguetá - SP, Brazil

description: Abstract This research evaluated the physicochemical parameters of a leachate sample from a controlled landfill in the city of Guaratinguetá-SP. The evaluation was conducted using spectrometric and spectrophotometric methods in order to assess the formation of persistent compounds. The selection of parameters was based on the CETESB Article 18 and CONAMA 357/05 Article 34, as well as organic characterization methods, such as FTIR, NMR (1H-NMR, 13C-NMR and APT), GC-MS, molar mass distribution and elemental analysis (CHN). Chemical and physical stability were also verified. The ammoniacal nitrogen concentration is 20 times greater than tolerance limit established by law (20 mg L-1). The Ba and Ni presented concentrations above those permitted by the legislation (CETESB Article 18 and CONAMA 357/05 Article 34). Those values of chemical oxygen demand (COD) and total organic carbon (TOC) were 1013 mg L-1 and 286 mg L-1, respectively. It was not possible to determine the biochemical oxygen demand (BOD) of slurry sample. In this sense, the biodegradability parameter for the slurry studied was Non-Determinable (ND), indicating that the organic matter of the slurry studied is recalcitrant. Recalcitrant humic substances of landfill leachate the present low polydispersity. These refractory acids play a detached role in carrying pollutants in the environment with regard to carrying toxic metals and pesticides. Finally, it was possible to verify that the humic acids’ complexing capacity indicates that hydroxyl and carboxyl groups may exist in larger quantities than the nitrogen and sulfur groups. Further, the high content of metals may indicate that the waste was not properly separated.
