Simulação da dispersão de poluentes atmosféricos e avaliação da qualidade do ar na área de abrangência do Distrito Industrial de Barcarena-PA

A poluição atmosférica é considerada atualmente um dos maiores problemas da sociedade contemporânea, por ameaçar sua qualidade de vida, pois gera impactos negativos no meio ambiente natural e antrópico. Dentre as formas de controle da poluição atmosférica de fontes fixas podem-se destacar a diluição das emissões na atmosfera devido aos efeitos de dispersão, a adoção de equipamentos de controle antes do lançamento dos gases ou a realocação de fonte, visto ser uma possibilidade a ser sugerida durante o procedimento de licenciamento ambiental de empreendimentos com potencial poluidor do ar. Atualmente modelos computacionais de dispersão de poluentes na atmosfera vêm sendo amplamente utilizados na simulação da concentração de poluentes, visando auxiliar órgãos ambientais no prognóstico da qualidade do ar ou suprir deficiências de monitoramento de emissões atmosféricas. O presente trabalho estudou a qualidade do ar e avaliou a dispersão de poluentes atmosféricos sobre Vila do Conde e áreas de influência do Distrito Industrial de Barcarena, no município de Barcarena, estado do Pará, com auxílio do modelo AERMOD View, visto a possibilidade de se estabelecer uma relação entre os níveis de emissões dos poluentes na fonte, com as concentrações dos mesmos no ar, bem como identificar pontos críticos de poluição. O Índice de Qualidade do Ar – IQA e as fragilidades das populações humanas das áreas afetadas pelos poluentes atmosféricos, também foram mensurados na pesquisa. A metodologia empregada permitiu mensurar a concentração média de poluentes atmosféricos durante um determinado tempo de modelagem, informações quanto ao alcance da pluma de poluentes foram alcançados também. São fornecidos ainda informações quanto à relação entre o valor de pico e o valor médio da concentração nas áreas receptoras, provocadas por empreendimentos com características operacionais similares ao modelado. Os resultados demostram que a influência de parâmetros meteorológicos, na dispersão de poluentes são indispensáveis e determinantes na previsão do impacto na qualidade do ar e no planejamento do uso e ocupação do solo de áreas que abrigam atividades poluidoras da atmosfera.

Biorremoção de corante direto de efluente industrial simulado utilizando levedura liofilizada

One of the most primal ways of human work already known is the tessellation and ginning for the production of fabric and clothing - what used to be, back in those days, statement of power and status. The arrival of the Industrial Revolution - in the middle of the XVIII century at Britain - increased the textile industry production, and what used to be manufactured and hard to obtain, starts then to be produced in mechanical ways and large-scale. Despite all the boost given to the economy of an expanding capitalist market, it should be pointed out the consequences of this major industrialization, especially the environmental ones, more and more concerning nowadays. The emissions of waste - that sometimes could be toxic - in effluents can possibly contaminate the aquatic ecosystems, causing a huge damage to its fauna and flora, affecting therefore all the biodiversity, reaching inclusively the humans. To avoid these problems, a few strategies have been taking place in the attempt to eliminate - or at least reduce - the amount of dye found in the effluents, and as the textile industry constantly leaves waste, efficient methods - that present good results in a short period of time - with a low cost are needed. The present study will test the bioremoval capacity of yeast (Saccharomyces cerevisiae) in contact with dyes in a fix concentration, diluted in water with three different pH values. The tests will be done duplicate, and after the concentration analyses - made by spectrophotometry - it will be analyzed which pH shows major efficiency in the dye removal and what is the influence of the biomass in this process

Efficiency in Brazil's industrial sectors in terms of energy and sustainable development

This article evaluates the efficiency of Brazil's industrial sectors from 1996 to 2009, taking into account energy consumption and respective contributions to the country's economic and social aspects. This analysis used a mathematical programming method called Data Envelopment Analysis (DEA), which enabled, from the SBM model and the window analysis, to evaluate the ability of industries to reduce energy consumption and fossil-fuel CO2 emissions (inputs), as well as to increase the Gross Domestic Product (GDP) by sectors, the persons employed and personnel expenses (outputs). The results of this study indicated that the Textile sector is the most efficient industrial sector in Brazil, according to the variables used, followed by these sectors: Foods and Beverages, Chemical, Mining, Paper and Pulp, Nonmetallic and Metallurgical.

Elemental composition evaluation in lichens collected in the industrial city of So Mateus Sul, Parana, Brazil

In this study, Canoparmelia texana lichenized fungi species was used as a passive biomonitor of the atmospheric pollution from the industrial city of So Mateus do Sul, PR, Brazil. Lichen samples collected from tree barks were cleaned, freeze-dried and analyzed by neutron activation analysis. Comparisons were made between the element concentrations obtained in lichens from this city and that from a clean area of Atlantic Forest in Intervales Park, SP. The high concentrations of elements As, Ca, Co, Cr, Fe, Hf, Sb, and Th found in lichens could be attributed to the emissions from a ceramic and an oil shale plants.

THE POTENTIAL OF INDUSTRIAL WASTE AND AGRICULTURAL FEEDSTOCK TOWARDS SUSTAINABLE BIOFUELS PRODUCTION: TECHNO-ECONOMIC AND ENVIRONMENTAL IMPACT PERSPECTIVES

This Ph.D. research is comprised of three major components; (i) Characterization study to analyze the composition of defatted corn syrup (DCS) from a dry corn mill facility (ii) Hydrolysis experiments to optimize the production of fermentable sugars and amino acid platform using DCS and (iii) Sustainability analyses. Analyses of DCS included total solids, ash content, total protein, amino acids, inorganic elements, starch, total carbohydrates, lignin, organic acids, glycerol, and presence of functional groups. Total solids content was 37.4% (± 0.4%) by weight, and the mass balance closure was 101%. Total carbohydrates [27% (± 5%) wt.] comprised of starch (5.6%), soluble monomer carbohydrates (12%) and non-starch carbohydrates (10%). Hemicellulose components (structural and non-structural) were; xylan (6%), xylose (1%), mannan (1%), mannose (0.4%), arabinan (1%), arabinose (0.4%), galatactan (3%) and galactose (0.4%). Based on the measured physical and chemical components, bio-chemical conversion route and subsequent fermentation to value added products was identified as promising. DCS has potential to serve as an important fermentation feedstock for bio-based chemicals production. In the sugar hydrolysis experiments, reaction parameters such as acid concentration and retention time were analyzed to determine the optimal conditions to maximize monomer sugar yields while keeping the inhibitors at minimum. Total fermentable sugars produced can reach approximately 86% of theoretical yield when subjected to dilute acid pretreatment (DAP). DAP followed by subsequent enzymatic hydrolysis was most effective for 0 wt% acid hydrolysate samples and least efficient towards 1 and 2 wt% acid hydrolysate samples. The best hydrolysis scheme DCS from an industry's point of view is standalone 60 minutes dilute acid hydrolysis at 2 wt% acid concentration. The combined effect of hydrolysis reaction time, temperature and ratio of enzyme to substrate ratio to develop hydrolysis process that optimizes the production of amino acids in DCS were studied. Four key hydrolysis pathways were investigated for the production of amino acids using DCS. The first hydrolysis pathway is the amino acid analysis using DAP. The second pathway is DAP of DCS followed by protein hydrolysis using proteases [Trypsin, Pronase E (Streptomyces griseus) and Protex 6L]. The third hydrolysis pathway investigated a standalone experiment using proteases (Trypsin, Pronase E, Protex 6L, and Alcalase) on the DCS without any pretreatment. The final pathway investigated the use of Accellerase 1500® and Protex 6L to simultaneously produce fermentable sugars and amino acids over a 24 hour hydrolysis reaction time. The 3 key objectives of the techno-economic analysis component of this PhD research included; (i) Development of a process design for the production of both the sugar and amino acid platforms with DAP using DCS (ii) A preliminary cost analysis to estimate the initial capital cost and operating cost of this facility (iii) A greenhouse gas analysis to understand the environmental impact of this facility. Using Aspen Plus®, a conceptual process design has been constructed. Finally, both Aspen Plus Economic Analyzer® and Simapro® sofware were employed to conduct the cost analysis as well as the carbon footprint emissions of this process facility respectively. Another section of my PhD research work focused on the life cycle assessment (LCA) of commonly used dairy feeds in the U.S. Greenhouse gas (GHG) emissions analysis was conducted for cultivation, harvesting, and production of common dairy feeds used for the production of dairy milk in the U.S. The goal was to determine the carbon footprint [grams CO2 equivalents (gCO2e)/kg of dry feed] in the U.S. on a regional basis, identify key inputs, and make recommendations for emissions reduction. The final section of my Ph.D. research work was an LCA of a single dairy feed mill located in Michigan, USA. The primary goal was to conduct a preliminary assessment of dairy feed mill operations and ultimately determine the GHG emissions for 1 kilogram of milled dairy feed.

Impact of Preindustrial Biomass-Burning Emissions on the Oxidation Pathways of Tropospheric Sulfur and Nitrogen

Ice core measurements (H2O2 and CH4/HCHO) and modeling studies indicate a change in the oxidation capacity of the atmosphere since the onset of the Industrial Revolution due to increases in fossil fuel burning emissions [e. g., Lelieveld et al., 2002; Hauglustaine and Brasseur, 2001; Wang and Jacob, 1998; Staffelbach et al., 1991]. The mass-independent fractionation (MIF) in the oxygen isotopes of sulfate and nitrate from a Greenland ice core reveal that biomass-burning events in North America just prior to the Industrial Revolution significantly impacted the oxidation pathways of sulfur and nitrogen species deposited in Greenland ice. This finding highlights the importance of biomass-burning emissions for atmospheric chemistry in preindustrial North America and warrants the inclusion of this impact in modeling studies estimating changes in atmospheric oxidant chemistry since the Industrial Revolution, particularly when using paleo-oxidant data as a reference for model evaluation.

Supplemental Data - Bioremediation of polluted air from an industrial plant using rotating biofilter reactor-based technology

Two microbial isolates (HDB, Hydrogen-Degrading Bacteria) obtained from industrial wastewater were inoculated into the rotating biofilter reactor 'Biowheel 2.0' and tested for the ability to purify gaseous flows containing benzene and non-methane volatile organic compounds (NMVOCs) released at an industrial plant. Different classes of gaseous flow were tested, namely 'cold box', 'in shell', and 'mix', all of them associated with the industrial process of 'mold-casting'. A significant increase in Removal Efficiency (RE) was recorded for benzene and NMVOCs in the inoculated 'Biowheel 2.0' biofilter, compared to uninoculated control. For each type of gaseous flow, odor impact was evaluated in the inlet and outlet flows at the industrial plant, using the test panel method and electronic nose technology. A significant drop in the amount of Olfactometric Units (O.U.) m-3 occurred in the gaseous flows treated with the bacterial consortium. The reported data demonstrate the ability of the consortium to degrade hydrocarbons, revealing its potential for bioremediation of polluted air emissions occurring at industrial plants.

Input-output-based genuine value added and genuine productivity in China's industrial sectors (1995-2010)

The rapid growth of China's economy has brought about huge losses of natural capital in the form of natural resource depletion and damages from carbon emissions. This paper recalculates value added, capital formation, capital stock, and related multifactor productivity in China's industrial sectors by further developing the genuine savings method of the World Bank. The sector-level natural capital loss was calculated using China's official input–output table and their extensions for tracing final consumers. The capital output elasticity in the productivity estimation was adjusted based on these tables. The results show that although the loss of natural capital in China's industrial sectors in terms of value added has slowed, the impacts on their productivity during the past decades is still quite clear.

Influence of denitrifiers abundance on N2O emissions in long term tillage system under a rainfed legume crop

Current studies about nitrous oxide (N2O) emissions from legume crops have raised considerable doubt, observing a high variability between sites (0.03-7.09 kg N2O–N ha−1 y -1) [1]. This high variability has been associated to climate and soil conditions, legume species and soil management practices (e.g. conservation or conventional tillage). Conservation tillage (i.e. no tillage (NT) and minimum tillage (MT)) has spread during the last decades because promotes several positive effects (increase of soil organic content, reduction of soil erosion and enhancement of carbon (C) sequestration). However, these benefits could be partly counterbalanced by negative effects on the release of N2O emissions. Among processes responsible for N2O production and consumption in soils, denitrification plays an importantrole both in tilled and no-tilled ropping systems [2]. Recently, amplification of functional bacterial genes involved in denitrification is being used to examine denitrifiers abundance and evaluate their influence on N2O emissions. NirK and nirS are functional genes encoding the cytochrome cd1 and copper nitrite reductase, which is the key enzyme regulating the denitrification process.

Characterization of gas emissions during heating of solid products

The emission of different harmful gases during the storage of solid fuels is a common phenomenon. The gases emitted during the heating process of those combustibles are the same as those emitted during combustion, mainly CO and CO2[1]. Nowadays, measurement of these emissions is mandatory. That is why in many industrial facilities different gas detectors are located to measure these gases. But it should be also useful if emissions could be predicted and the temperatures at the beginning of the emission process could be determined.

The Sustainability Impact of the EU Emissions Trading System on the European Industry. Bruges European Economic Policy (BEEP) Briefing 17/2007

This BEEP explains the mechanism of the EU Emissions Trading System (ETS) for the greenhouse gas carbon dioxide and explore into its likely sustainability impact on European industry. In doing so, it focuses on energy-intensive industries like cement, steel and aluminium production as well as on the emerging hydrogen economy. The BEEP concludes that at the moment it is still very inconsistently implemented and has a fairly narrow scope regarding greenhouse gases and involved sectors. It may also give an incentive to relocate for energy-intensive industries. In its current format, the EU ETS does not yet properly facilitate long term innovation dynamics such as the transition to a hydrogen economy. Nevertheless, the EU ETS is foremost a working system that – with some improvements – has the potential to become a pillar for effective and efficient climate change policy that also gives incentives for investment into climate friendly policies.

Something Worth Fighting For: The Evolution of Lobbying Coalitions in the Emissions Trading System. Bruges Political Research Papers 50/2015.

This thesis attempts to understand who fought for influence within the European Union’s policy area of the Emissions Trading System (ETS). The ETS is a key aspect of the European Union’s (EU) climate change policy and is particularly important in light of the conclusions at the 2015 United Nations Climate Change Conference in Paris. It was first established in 2003 with Directive 2003/87/EC and completed its first major revision in 2008 with Directive 2009/29/EC. Between these two key Directives, the interplay between industrial and environmental incentives means that the ETS has created a dynamic venue for divergent interest groups. So as to identify the relevant actors, this paper applies the Advocacy Coalition Framework (ACF) of Sabatier. Using position papers, semi-structured interviews, and unpublished documents from the EU institutions, this paper answers it primary research question in its identification of an economy-first and an environment-first lobbying coalition. These coalitions have expanded over time with the environment-first coalition incorporating Greenpeace and the economy-first coalition expanding even further in both scope and speed. However, the economy-first coalition has been susceptible to industry-specific interests. In its application of the ACF, the research shows that a hypothesised effect between the ACF’s external events and these lobbying coalitions is inconclusive. Other hypotheses stemming from the ACF relating to electricity prices and the 2004 enlargement seem to be of significance for the relative composition of the lobbying coalitions. This paper finds that there are certain limitations within the ACF. The findings of this thesis provide a unique insight into how lobbying coalitions within a key EU policy area can form and develop.
