Full textAbstract:
In African nations, national and regional development targets for water and energy sectors seldom consider the nexus between the two, risking imbalances and inefficiencies in resource allocation and utilization. A typical example is the development and expansion of biofuel in the Wami Ruvu River Basin, Tanzania (WRB). Water Evaluation and Planning (WEAP) model was applied to the WRB to investigate the Water Energy Nexus (WEN), specifically, whether the development plan calling for biofuel expansion is a sound approach. Results show that WEN is much stronger in the biofuel irrigation consuming 69.3% and 61% of total biofuel’s water and energy requirement, respectively. By 2035, the nexus continues to be stronger, consuming 54.5% and 49% of total biofuel’s water and energy requirement, respectively, and thus first generation biofuels use much more resources in the growing than the refining process. An additional 768.2 million meter cubic of water and 413.4 million kWh of energy are needed for planned biofuel expansion, reallocating water to biofuels in water-scarce regions inherit related problems to other sectors such as increasing water use for the industry, agriculture, and energy sector by 67%, 45%, and 9%, respectively, which could further exacerbate stresses on water and energy supplies in the basin. Biofuel generation rely heavily on energy imports, as it consumes substantially more energy than it produces. Policies should promote the coordinated development of sustainable biofuel programs that are less water intensive with very low inputs of fossil fuels.

The current state and the future of the biofuels for transport sectors in Poland were presented in the paper. Because of the importance of legal conditions, crucial directives and acts affecting the shape of these sectors were discussed. The scoring multicriteria M.E. Porter method was used to research attractiveness of the national biofuel sectors, i.e. the sectors of biodiesel and bioethanol produced from edible material (so-called first generation biofuels) as well as the sector of bioethanol produced from inedible material, mainly from lignocellulose (so-called second generation biofuel). Various factors of macro- and microenvironment of first generation biofuels caused regular reduction of their attractiveness. However, the sector of second generation bioethanol, which is not produced at industrial scale in Poland now, is characterized by relatively high and growing attractiveness.

Full textAbstract:
This study applies a partial equilibrium forest sector model to analyse the impacts of biofuel deployment for road transport in the Nordic countries, when alternative use of the biomass resources and transport sector electrification are considered. We foresee a strong electrification of the transport sector, resulting in a demand for biofuels of approximately 2.5 billion L in 2035 and 1 billion L in 2050 in a 100% fossil-free base scenario. The simultaneous increase in demand from pulping industries and biofuel will cause an overall increase in wood use, of which the biofuels share will constitute approximately 20–25%. The utilization of harvest residues will increase more than 300% compared to the current level, since biofuel production will reallocate some of the current raw material used in district heating. Biofuel consumption in road transport will likely reduce after 2040 due to increasing electrification, but it is plausible that the declining domestic demand will be replaced by increasing demand from international biofuel markets in aviation and shipping. The main uncertainties in the scenarios are the future costs and profitability of forest-based biofuel technologies and the public acceptance of the close to 100 TWh of new renewable electricity production needed for the electrification of Nordic road transport.

Abstract The paper provides development status in the EU biofuel market by giving a comprehensive picture of production, consumption and production capacity of the first generation biofuels – biodiesel and bioethanol, while giving also insights into issues related to biofuel feedstocks such as crop production and harvested area. Development of crop production and harvested area for the crop products, used as a feedstock in the production of biofuels, have shown the changes in agriculture due to the growing trend of the biofuel sector. Additionally, the increasing production and consumption of biofuels may also affect the prices of agricultural commodities used as a feedstock for bioenergy production.

Purpose The purpose of this paper is to determine the status of policy design and policy implementation in the biofuel sector in Ireland. The focus of the work addresses the overarching operational context of the biofuel sector in Ireland and the role of different actors in shaping and resolving inconsistencies in policy outlook and practice. Design/methodology/approach This study used a qualitative research approach involving a series of semi-structured interviews with members of the relevant sub-groups concerned. This study sought to address two questions – whether current or proposed policy is likely to affect consumption of indigenous biofuel feedstocks in the biofuel sector and what are the controlling factors in the demand for indigenous feedstocks for biofuel. Findings Outcomes suggest that while Irish government policy recognises the need to support the development of renewable energy, it also operates under a number of parallel and potentially inconsistent paradigms in relation to biofuels as a renewable energy commodity. It is contended that the outcome of this position is a lack of coherent and coordinated policy in the area of biofuel production, including second generation biofuel using indigenous feedstocks. Originality/value This paper provides a new cross sectoral perspective on the status of biofuel policy in Ireland with particular reference to second generation biofuel feedstocks. It focuses analysis on the nature of policy-operational inconsistencies and the need for a deeper ecological perspective in governance.

Abstract During the last 10 years biofuel production and utilization in the European Union have become more extensive owing to support provided by the relevant EU Directives. Achievement of the main targets defined by Directives was not simple, being confronted with various barriers. Latvia is one of the EU member-countries that have set an ambitious goal as to the production of biofuel and its use in transport. The authors summarize the major achievements of the country in this area and analyze the main barriers to implementation of biofuels in the transport sector, providing an outlook on the current status of the bioenergy and the transport situation in Latvia.

Full textAbstract:
Current policies in energy sector address issues including environmentally friendly technologies, clean and renewable energy supplies and encourage more efficient energy use. The biofuel policy aims to promote production and consumption of fuels made from biomass. Despite the presence of both positive and negative effects of biofuels the world production and consumption of biofuels have been increasing significantly. To a large extent, this is due to an active public policy in the field of stimulating the production and consumption of biofuels. The volume of biofuel production in the leading countries (USA, Brazil and the EU) has been analyzed. The influence of public policy in the sphere of biofuel production and consumption on energy, environment and food security of the state has been examined. Multivariable and paired correlation as well as regression analysis aimed to determine the price dependence of the main crops used as feedstock for biofuels production, the volume of their production or processing for biofuels and the volumes of biofuel production have been carried out. As a result of this analysis the impact of the public policies in biofuels on the еnergy, environment and food security has been identified.

Full textAbstract:
In this study, various national strategies and programs are described by planning instruments. The TIEB (Thailand Integrated Energy Blueprint), which includes six programs (AEDP, PDP, EEDP, ODP, GDP, REDP), aims to regulate renewable energy and improve the use of biofuel. In addition, the potential of second-generation biofuels is estimated with different residue extractions of second-generation biomasses: 20% (scenario 1), 44% (scenario 2), and 66% (scenario 3). Based on the production potentials that were estimated, CO2 will decrease 1.3–3.5 megatons in the gasoline sector, and 1.4–3.8 megatons in the diesel sector under scenario 1. In scenario 2, we estimated decreases of 2.8–7.7 mega tons and 3.2–8.4 mega tons of CO2 for the gasoline and diesel sectors, respectively. Finally, scenario 3 is expected to reduce the CO2 concentration by 4.2–11.6 megatons in the gasoline sector, and by 4.7–12.6 megatons in the diesel sector. We also estimate the economic potential of a second-generation biofuel with the view of emissions trading. For bioethanol and biodiesel, respectively, 27–74 million USD and 30–81 million USD could be realized in scenario 1, 60–163 million USD and 67–178 million USD in scenario 2, and 90–244 million USD and 100–267 million USD in scenario 3. We conclude that the future potential of second-generation biofuels in Thailand is optimistic, and that they can provide both environmental and economic benefits to the country.

We examined four evolution paths of the biofuel sector using a partial equilibrium world agricultural sector model in CARD that includes the new RFS in the 2007 EISA, a two-way relationship between fossil energy and biofuel markets, and a new trend toward corn oil extraction in ethanol plants. At one extreme, one scenario eliminates all support to the biofuel sector when the energy price is low, while the other extreme assumes no distribution bottleneck in ethanol demand growth when the energy price is high. The third scenario considers a pure market force driving ethanol demand growth because of the high energy price, while the last is a policy-induced shock with removal of the biofuel tax credit when the energy price is high. Standard results hold where the biofuel sector expands with higher energy price, raising the prices of most agricultural commodities through demand side adjustment channels for primary feedstocks and supply side adjustment channels for substitute crops and livestock. On the other hand, the biofuel sector shrinks coupled with opposite impacts on agricultural commodities with the removal of all support including the tax credit. Also, we find that given distribution bottlenecks, cellulosic ethanol crowds marketing channels resulting in a corn-based ethanol price that is discounted. The blenders' credit and consumption mandates provide a price floor for ethanol and for corn. Finally, the tight linkage between the energy and agricultural sectors resulting from the expanding biofuel sector may raise the possibility of spillover effects of OPEC's market power on the agricultural sector.

Full textAbstract:
The use of agricultural-based biofuels has expanded. Discussions on how to assess green house gas (GHG) emissions from biofuel policies, specifically on (non-observed) land-use change (LUC) effects involve two main topics: (i) the limitations on the existing methodologies, and (ii) how to isolate the effects of biofuels. This paper discusses the main methodologies currently used by policy-makers to take decisions on how to quantify LUCs owing to biofuel production expansion. It is our opinion that the concerns regarding GHG emissions associated with LUCs should focus on the agricultural sector as a whole rather than concentrating on biofuel production. Actually, there are several limitations of economic models and deterministic methodologies for simulating and explaining LUCs resulting from the expansion of the agricultural sector. However, it is equally true that there are avenues of possibilities to improve models and make them more accurate and precise in order to be used for policy-making. Models available need several improvements to reach perfection. Any top model requires a concentration of interdisciplinary designers in order to replicate empirical evidence and capture correctly the agricultural sector dynamics for different countries and regions. Forgetting those limitations means that models will be used for the wrong purposes.

Full textAbstract:
The increasing demand for transportion fuels has led most countries around the world to look for alternatives to the predominant fossil fuels in the sector. Furthermore, the needs for security of energy supply, social – economic and sustainable development are among the factors driving the search for alternative fuels with regard to the fact that most oil producing countries are politically unstable. Developing countries are not an exception and are also formulating policies that will enhance development of alternatives to fossil fuels. This study analyses the opportunities and consequences of the development of the biofuels industry in Zambia from a local, regional and global perspective with regard to policy, technical, socio – economic, environment and sustainability considerations. From analysis of global, regional and local situation, the development of biofuels in Zambia is simulated using Long – range Energy Alternatives Planning system (LEAP) under different policy assumptions with consideration of current and future demands. Furthermore, the socio – economic and environmental consequences are modelled in LEAP using these policies and other assumptions which include demand – cost projections. The environmental loadings are also simulated for the period with the assumption that biofuels are zero net emitters of green house gases. Land requirements are then estimated from these results for the simulated period. A model of illustrative scenarios for implementation of different biofuels policies is developed which can be used to monitor and analyse their consequences by adjusting the major parameters depending on varying circumstances. The results of this study show that there is considerable potential for feedstock, land, water and mature technology for production of both biodiesel and bioethanol to meet blending demands for the simulated period. There is considerable potential for production of bioethanol from sugar cane and sweet sorghum using the well established fermentation processes. Biodiesel can be produced from jatropha and other oil bearing plants. Most of the current fleet of vehicles in Zambia was manufactured after 1990, thus there is little or no modification required on engines to run on low biofuel blends considered in the simulations. It is clear from the results of the simulation that biofuel demand for blends of 5% in 2015 rising to 10% in 2030 with current yields required for both can be achieved with the available land ad water resources. To achieve the 10% blending target set in the simulated period for bioethanol and biodiesel from sugar cane and jatropha, land required is 4,480Ha and 47,000Ha respectivey for growing this feedstock at current yields for the region. The GHG reduction would be equivalent to the 10% in 2030 if we assume that biofuels are zero net emitters. However, policies have to be formulated and implemented which should include manadatory blending targets and incentives on tax and investments.

Most of the time when developing policies for the promotion of future biofuel, the social dimension of sustainable development is neglected. But it is important to incorporate both social and economic issues along with environmental issues for a successful sustainability strategy because sustainable development depends on all three aspects of sustainability. This paper focuses on the sustainable development of liquid biofuel for the transport sector.The global transport sector is booming as is the need for energy. With the growing concern about climate change, governments of developed countries have been implementing different policy directives to promote biofuel as an alternative source of energy. But strategies implemented to fulfill the target of mitigating effects of climate change have exposed negative effects of liquid biofuels on both environment and society. This paper reviewed information on liquid biofuels and their effects on environment, society and economy and analyzed them from a sustainable development point of view. Although scientists have developed biofuels through advanced technology that seem to have less negative effects than traditional biofuels, they are still on a trial basis. In addition to this the effects of these biofuels are also need to be tested on a commercial basis in order to ensure their sustainability. Due to these considerations the process of switching from traditional biofuel to advanced biofuels will require time. It is imperative to develop sustainable ways of production and use of available biofuels which do not harm nature or exploit vulnerable communities. Biofuel policies also need to be studied thoroughly in order to find weaknesses and pitfalls. Although numerous studies related to specific issue like indirect land use change, GHG emission, biofuel policies or the biofuel market etc. have been conducted, it is rare to find a study that takes into consideration of all three aspects (economy, society and environment) of sustainable development. After reviewing and analyzing the literature, this thesis has come to a conclusion that the potential of liquid biofuel in the future transport sector is unlimited. But due to the negative effects on environment and society it has not achieved sustainability. Moreover the expense of production and lack of investment in the sector has made it economically unsustainable. But, it is possible to change the scenario by implementing proper policies in a way that the social and environmental issues that happened in the past do not happen again and the sector can achieve sustainability.

Full textAbstract:
This thesis analyses two strategies for decreasing anthropogenic carbon dioxide (CO2) emissions: to capture and store CO2, and to increase the use of biomass. First, two concepts for CO2 capture with low capture penalties are evaluated. The concepts are an integrated gasification combined cycle where the oxygen is supplied by a membrane reactor, and a hybrid cycle where the CO2 is captured at elevated pressure. Although the cycles have comparatively high efficiencies and low penalties, they illustrate the inevitable fact that capturing CO2 will always induce significant efficiency penalties. Other strategies are also needed if CO2 emissions are to be forcefully decreased. An alternative is increased use of biomass, which partially could be used for production of motor fuels (biofuels). This work examines arguments for directing biomass to the transport sector, analyses how biofuels (and also some other means) may be used to reduce CO2 emissions and increase security of motor fuel supply. The thesis also explores the possibility of reducing CO2 emissions by comparatively easy and cost-efficient CO2 capture from concentrated CO2 streams available in some types of biofuel plants. Many conclusions of the thesis could be associated with either of three meanings of the word sense: First, there is reason in biofuel production – since it e.g. reduces oil dependence. From a climate change mitigation perspective, however, motor fuel production is often a CO2-inefficient use of biomass, but the thesis explores how biofuels’ climate change mitigation effects may be increased by introducing low-cost CO2 capture. Second, the Swedish promotion of biofuels appears to have been governed more by a feeling for attaining other goals than striving for curbing climate change. Third, it seems to have been the prevalent opinion among politicians that the advantages of biofuels – among them their climate change mitigation benefits – are far greater than the disadvantages and that they should be promoted. Another conclusion of the thesis is that biofuels alone are not enough to drastically decrease transport CO2 emissions; a variety of measures are needed such as fuels from renewable electricity and improvements of vehicle fuel economy.QC 20100823

O segmento de fornecedores de máquinas e equipamentos para a indústria do setor sucroenergético brasileiro desempenha um papel significativo na atividade inovativa da cadeia do etanol. Ao mesmo tempo, o segmento é constituído basicamente por empresas nacionais, sendo o Brasil o principal pólo de desenvolvimento do setor. Por essas razões, este trabalho visa abordar duas áreas intrinsecamente ligadas: a de processo de desenvolvimento de novos produtos no segmento, que o permite assegurar e criar vantagens competitivas possibilitando, assim, uma posição competitiva de liderança no mercado internacional do etanol, e a questão de como o mercado externo afeta essa dinâmica. Para tanto, foram realizados dois estudos de casos em empresas nacionais do segmento, por meio de entrevistas em profundidade conduzidas por meio de um roteiro semi-estruturado de perguntas. Os resultados apontaram três modelos de desenvolvimento de novos produtos, todos orientados para o mercado. Os dois primeiros referem-se a uma única organização e se diferenciam em função da forma como são concebidos, o que, por sua vez, é resultado das diferentes concepções estratégicas de seus projetos; enquanto um visa desenvolver uma nova rota tecnológica para o etanol, tendo um caráter mais radical, o segundo atende as necessidades pontuais dos clientes, caracterizando-se como incremental. O terceiro é adotado pela outra empresa pesquisada; apesar de se assemelhar ao modelo incremental citado, apresenta distinções relevantes nos processos decisórios, o que traz a necessidade de uma caracterização específica. Também se constatou que em nenhum modelo adotado o mercado externo atua ativamente como fonte de idéias, uma vez que o mercado interno mostra-se mais lucrativo. Mesmo com os baixos preços do petróleo, o cenário mostra-se favorável à expansão da produção mundial de etanol, visto que diversos países estão adotando programas de biocombustíveis como forma de diversificar a matriz energética, o que vai ao encontro da continuidade da principal motivação à atividade exportadora pontuada pelos entrevistados, qual sejam, de aproveitamento das oportunidades do mercado externo. No entanto, o alto preço do aço no mercado interno, a falta de incentivos governamentais à atividade exportadora no segmento, as legislações de segurança e ambiental e a baixa disponibilidade de crédito em importantes mercados de exportação surgem como barreiras a esse cenário. As dimensões identificadas da distância psíquica foram o ambiente institucional/legal, a instabilidade política, a existência de fabricantes locais e as diferentes rotas tecnológicas existentes nos mercados de exportação. As competências organizacionais técnicas mostraramse decisivas para a atividade de exportação, colocando o know how e a expertise brasileira na produção de etanol como fundamentais para as vendas externas. Por fim, a forma de seleção dos mercados alvo das exportações em conjunção com os canais de exportação via parceiros, denotam um envolvimento ainda tímido com o mercado externo. Ao mesmo tempo, as inovações também não se mostraram significantes para a atividade exportadora, uma vez que a escolha dos produtos, em função de sua natureza, se dá em torno da produtividade alcançada e não em termos de diferenciação, podendo-se inferir que as organizações não possuem uma estratégia estruturada de internacionalização.The segment of suppliers for machinery and equipment for the biofuel sector industry has a significant role in the ethanol chains innovative activity. At the same time, the segment is basically constituted of national enterprises, Brazil being the main pole of development in the sector. For such reasons, this thesis seeks to approach two areas intrinsically linked: the process of development of new products in the segment, which allows it to assure and create competitive advantages, thus making possible a position of competitive international ethanol market leadership, and the issue of how the external market affects this dynamic. For such, two case studies of national enterprises have been accomplished by interviews in profundity carried out through a semi-structure script of questions. The results indicated three new products development models, all of them market-oriented. The first two are concerned to a single organization and are set apart for the way they are conceived, which, in its turn, is the result of the different strategic conceptions of their projects: whereas one seeks to develop a new technologic rout for ethanol, presenting a more radical nature, the other addresses the specific need of the clients, characterizing itself as incremental. The third is adopted by another researched enterprise; and despite presenting similarities to the incremental model cited, this model presents relevant distinctions in the decision-making process, which brings the necessity of a specific characterization. It has also been noted that in no adopted model the external market acts actively as a source of ideas, once the internal market appears more lucrative. Even with petroleums low prices, the scenario appears favorable to the expansion of global ethanol production, given that many countries are adopting biofuel programs as a mean to diversify their energetic pattern, which goes in favor of the continuality of the main motivation to the exporting activity pointed by the interviewees, whichever it may be, of profiting from the external market opportunities. However, steels high price in the internal market, the lack governmental investments to the exporting activity in the segment, the security and environmental legislations and the low credit availability in main exporting markets appear as obstacles to this scenario. The identified dimensions of the psychic distance were the institutional/legal environments, the political instability, the existence of local manufactures and the different technological paths existing in the exporting markets. The technical organizational abilities appear decisive to the exporting activity, situating the knowhow and Brazilian expertise in the ethanol production as fundamental to the external sales. At last, the manner of selection of the exporting target markets, in conjunction with the exporting channels thru partners, denotes a still timid involvement with the external market. At the same time, the innovations still do not present significance to the exporting activity, once the choice of product, in result of its nature, occurs around the productivity reached and not in terms of distinction, allowing to deduce that the organizations do not possess a structured strategy of internationalization.

Full textAbstract:
Sweden has the goal of reaching a fossil independent transportation sector by 2030. Two ways to reach the goal is to increase the use of electric vehicles or produce more biofuels. Both alternatives could be powered by forest residue, which is an underutilized resource in the country. Electricity could be produced in a biomass fired Combined Heat and Power (CHP) plant, and biofuel could be produced in a biorefinery through gasification of biomass and Fischer-Tropsch process. When located in Stockholm County, both system can also distribute heat to the district heating system. It is however important to use the biomass in an energy-efficient way. The scope of this work has been to analyze the efficiency together with environmental and economic aspects of the two systems. To assess the efficiency and environmental impact of the two systems a forest to wheel study was made of the systems where the product was studied from harvesting of forest residue to driving the vehicle. The studied functional units were: kilometers driven by vehicle, kWh of district heating, CO2-equivalents of greenhouse gases and MWh of forest residue. The system using CHP technology and electric vehicles outperformed the biorefinery system on the two first functional units. Using the same amount of forest residue more than twice as much district heating and almost twice as many driven kilometers were produced in this system. The study also showed that both systems avoids significant greenhouse gas emissions and can be part of the solution to decrease emissions from road transportation. The profitability of investing in a CHP plant or a biorefinery was calculated through the net present value method. It showed that the expected energy prices are too low for the investments to be profitable. The CHP plant investment has a net present value of -1.6 billion SEK and the biorefinery investment has a net present value of -4.6 billion SEK. Furthermore, the biorefinery investment entails higher risk due to the high investment cost and uncommercialized technology. Both systems face barriers for implementation, these barriers have been studied qualitatively.Sverige har som mål att skapa en fossiloberoende fordonsflotta till år 2030. Två vägar som pekats ut för att nå målet är att öka användningen av eldrivna fordon eller att producera mer biobränsle. Båda alternativen kan drivas av skogsavfall, en råvara som det finns gott om i Sverige. Elektricitet kan produceras av skogsavfallet i ett kraftvärmeverk, och biobränsle i ett bioraffinaderi genom användning av förgasning och Fischer-Tropschmetoden. I Stockholms län skulle båda systemen dessutom kunna producera värme till Stockholms fjärrvärmesystem. Det är dock viktigt att använda skogsavfallet på ett resurseffektivt sätt. Därför undersöker detta arbete effektiviteten av de två olika systemen tillsammans med en analys av växthusgasutsläpp och ekonomiska förutsättningar. För att kunna utvärdera effektiviteten och klimatpåverkan av de två olika systemen utfördes en ”skog-till-hjul”-analys där produkten undersöktes från ursprunget, till drivandet av ett fordon. För att utföra studien definierades fyra funktionella enheter. De funktionella enheterna var: körsträcka med bil mätt i kilometer, kWh fjärrvärmeproduktion, CO2 ekvivalenter av växthusgasutsläpp och MWh skogsavfall. Studien visade att systemet där skogsavfallet används i ett kraftvärmeverk för att producera elektricitet och ladda elbilar hade bättre resultat i de två första funktionella enheterna. Systemet producerade nästan dubbelt så lång körsträcka och mer än dubbelt så mycket fjärrvärme som systemet där skogsavfallet används i ett bioraffinaderi och biobränslet används i dieselbilar. Studien visade även att båda system kan bidra till att sänka växthusgasutsläppen från transportsektorn. Lönsamheten att investera i ett kraftvärmeverk eller bioraffinaderi beräknades med nuvärdesmetoden. Studien visade att de förväntade framtida energipriserna är för låga för att investeringarna ska bli lönsamma. Kraftvärmeanläggningen hade ett nuvärde på -1.6 miljarder kronor, och bioraffinaderiet ett nuvärde på -4.6 miljarder kronor. Dessutom ansågs investeringen i ett bioraffinaderi vara en hög risk på grund av den höga investeringskostnaden och att tekniken idag inte är kommersialiserad. Det finns även en rad andra barriär för att genomföra de två olika systemen, dessa barriärer har studerats kvalitativt i arbetet.

Full textAbstract:
The recent trends in the international crude oil price have brought back the interest of researchers to the importance of the practiced by the government fuel pricing policy for the domestic economy, especially in the developing world. Brazil constitutes a particularly interesting case when it comes to the government participation in the domestic fuel sectors. The state-owned oil company Petrobras acts as a price-setter for all petroleum derivatives sold in the country. This policy, however, has had severe negative consequences for the Brazilian fuel sector and especially for the domestic ethanol industry. Thus, the main goal of this study is to provide a basis for the development of a reformed pricing policy, which is more suitable for the needs of the country and does not have severe negative impact on the domestic economy. For this purpose, this work is divided into three chapters that interrelate and contribute for the achieving of the objective. The first chapter focuses on a comparative analysis of the dynamic correlation between the domestic fuel prices and international crude oil in Brazil, Germany and the United States. The results of the performed MGARCH-DCC estimation for the three countries provide empirical evidence for the differences existing between the pass-through of volatility from international oil markets to the domestic economy. The artificially established by the government ex-refinery prices of petroleum derivatives in Brazil led to lower correlation in comparison to Germany and the U.S. - two countries where the government does not intervene in the formation of the prices of petroleum derivatives. The used combination of free fuel prices and flexible fiscal policy, as the case of Germany, can induce competitiveness in the domestic fuel sector and at the same time keep domestic prices stable - an example that should be considered by policy makers in Brazil. The second chapter goes one step further by including the biofuel sectors in the analysis in order to verify if there exist differences in the biofuel-related price transmission mechanisms in the three countries of interest. The obtained results of the performed cointegration tests and estimation of VECM show that while in Brazil and in the U.S. the ethanol sectors are characterized by a stable relationship between the examined price series, in Germany such a strong and permanent link is not observed - a result that can be attributed to the changes in the policy regarding biofuels in the country, as well as to the specific characteristics of its biofuel-related sectors. The third chapter of the study gives a continuation to the analysis by focusing on the situation in Brazil and the hypothetical effects of a free fuel pricing policy. A simulated free gasoline price for the period between 2007 and 2016 is constructed and the hypothetical responses of the ethanol sector are calculated, using the obtained by the estimation of a structural VEC model demand elasticities. The results show that such a change in the policy would have led to higher ethanol prices in the state of São Paulo, making it more profitable for sugarcane producers to engage in the production of biofuel instead of sugar, which would have been beneficial for the sector, especially after 2011 when it entered a severe crisis. The final conclusion of this work is that there is a need for reformulating the practiced fuel pricing policy in Brazil in order to help ethanol regain its previous competitiveness as a substitute for conventional fossil fuels and to reestablish itself in the country\'s energy matrix.As recentes tendências do preço internacional do petróleo renovaram o interesse dos pesquisadores na importância da política de formação de preços de combustíveis praticada pelo governo para a economia doméstica, especialmente em países em desenvolvimento. O Brasil constitui um caso particularmente interessante no contexto de intervenção do governo em setores domésticos de combustíveis: A empresa petrolífera estatal Petrobras atua como price-setter para todos os derivados de petróleo comercializados no país. Essa política, no entanto, trouxe graves conseqüências negativas para o setor brasileiro de combustíveis - e especialmente para a indústria nacional de etanol. Nesse contexto, o principal objetivo deste estudo foi fornecer uma base para o desenvolvimento de uma política de preços reformada, que seja mais adequada às necessidades do país e não tenha um impacto tão negativo para a economia doméstica. Para tanto, a presente pesquisa foi dividida em três capítulos distintos. O primeiro capítulo aborda uma análise comparativa da correlação dinâmica entre os preços domésticos dos combustíveis e o preço internacional do petróleo para o Brasil, a Alemanha e os Estados Unidos. Os resultados da estimativa de um modelo MGARCH-DCC realizada para os três países fornecem evidências empíricas das diferenças existentes entre o pass-through da volatilidade do mercado internacional de petróleo para a economia doméstica. O estabelecimento artificial dos preços de refinaria pelo governo brasileiro levou a uma correlação menor em comparação à Alemanha e aos EUA - dois países onde o governo não intervém nos preços dos combustíveis. Uma combinação de política de preço dos derivados do petróleo livre e uma política fiscal flexível como na Alemanhã poderia trazer competitividade para o setor doméstico de combustíveis e ao mesmo tempo garantir um preço estável ao consumidor - um exemplo que deve ser considerado pelo governo brasileiro. O segundo capítulo vai um passo além, incluindo os setores de biocombustíveis na análise, a fim de verificar se existem diferenças nos mecanismos de transmissão de preços relacionados aos biocombustíveis nos três países estudados. Os resultados obtidos nos testes de cointegração e na estimativa de um modelo VEC mostram que, enquanto no Brasil e nos EUA os setores de etanol se caracterizam por uma relação estável entre as séries de preços examinadas, na Alemanha não se observa um vínculo tão forte e permanente - um resultado que pode ser atribuído às mudanças na política de biocombustíveis no país, bem como às características específicas de seus setores de biocombustíveis. O terceiro capítulo do estudo dá continuidade à análise, focando na situação do Brasil e nos efeitos hipotéticos de uma política de preços livres dos combustíveis. Uma simulação de preço livre para a gasolina no período entre 2007 e 2016 foi construído e as respostas hipotéticas do setor de etanol foram calculadas, usando as elasticidades da demanda obtidas pela estimação de um modelo VEC estrutural. Os resultados mostram que uma política mais liberal teria levado ao aumento no preço do etanol no estado de São Paulo, tornando a produção de etanol mais lucrativa do que o açúcar para os produtores de cana, o que teria sido benéfico para o setor - especialmente depois de 2011, quando ele entrou em uma grave crise. A conclusão final deste trabalho é de que se faz necessária uma reformulação da política de formação de preços praticada no Brasil, a fim de ajudar o etanol a recuperar sua competitividade como substituto a combustíveis fósseis e a se restabelecer na matriz energética do país.

Full textAbstract:
The aim of this study was to investigate and compare the climate impact from different arable land use options and protein feeds aimed for cattle. This has been made by executing two life cycle assessments (LCAs). The first LCA aimed to compare the following three arable land use options: Cultivation of wheat used for production of bioethanol, carbon dioxide and DDGS Cultivation of rapeseed used for production of RME, rapeseed meal and glycerine Fallow in the form of long-term grassland The second LCA aimed to compare the three protein feeds DDGS, rapeseed meal and soybean meal. In the LCA of arable land, the functional unit 1 ha arable land during one year was used and the LCA had a cradle-to-grave perspective. The LCA of protein feeds had the functional unit 100 kg digestible crude protein and had a cradle-to-gate perspective, hence the use and disposal phases of the feeds were excluded. Bioethanol, DDGS and carbon dioxide produced at Lantmännen Agroetanol, Norrköping, were investigated in this study. The production of RME, rapeseed meal and glycerine were considered to occur at a large-scale plant in Östergötland, but no site-specific data was used. Instead, general data of Swedish production was used in the assessment. The wheat and rapeseed cultivations were considered to take place at the same Swedish field as the fallow takes place. The protein feed DDGS was produced at Lantmännen Agroetanol and the rapeseed meal was assumed to be produced at a general large-scale plant in Sweden. In the soybean meal scenario, a general case for the Brazilian state Mato Grosso was assumed and no specific production site was investigated. Data required for the LCAs was retrieved from literature, the LCI database Ecoinvent and from Lantmännen Agroetanol. In the LCA of arable land use options, system expansion was used on all products produced to be able to compare the wheat and rapeseed scenarios with the fallow scenario. In the LCA of protein feeds, system expansion was used on co-products. The products in the arable land use options and the co-products in the protein feed scenarios are considered to replace the production and use of products on the market with the same function. The result shows that the best arable land use option from a climate change perspective is to cultivate wheat and produce bioethanol, carbon dioxide and DDGS. This is since wheat cultivation has a higher yield per hectare compared to rapeseed and therefore a bigger amount of fossil products and feed ingredients can be substituted. To have the arable land in fallow is the worst option from a climate change perspective, since no products are produced that can substitute alternative products. Furthermore, the result shows that DDGS and rapeseed meal are to prefer before soybean meal from a climate change perspective, since soybean meal has a higher climate impact than DDGS and rapeseed meal. This can be explained by the smaller share of co-products produced in the soybean meal scenario compared to the DDGS and rapeseed meal scenarios. Since the production and use of co-products leads to avoided greenhouse gas emissions (since they substitute alternatives), the amount of co-products being produced is an important factor. A sensitivity analysis was also executed testing different system boundaries and variables critical for the result in both LCAs. The conclusion of this study is that arable land should be used to cultivate wheat in order to reduce the total climate impact from arable land. Furthermore, it is favorable for the climate if DDGS or rapeseed meal are used as protein feeds instead of imported soybean meal.

Devido ao maior interesse por biocombustíveis, indústrias brasileiras iniciaram, recentemente, a produção de etanol também a partir de grãos de milho, gerando um resíduo com potencial de uso como ingrediente em rações para animais, o DDGS (grãos secos de destilaria com solúveis). Por resultar de processos de fermentação de grãos de milho por leveduras e enzimas, este resíduo possui um elevado teor proteico e baixo teor de carboidratos solúveis, o que o torna boa fonte de proteína vegetal em rações para animais. Além do baixo custo, possíveis benefícios relacionados aos resíduos de leveduras e enzimas restantes da fermentação também contribuem para seu potencial de mercado. Desta forma, com este trabalho, objetivou-se avaliar a viabilidade de inclusão do DDGS do milho em dietas para juvenis de Piaractus mesopotamicus em substituição ao farelo de soja. Para tal, foram realizados três ensaios experimentais. No primeiro ensaio avaliaram-se os coeficientes de digestibilidade aparente (CDA) de nutrientes do DDGS para juvenis de P. mesopotamicus (13±0.3 gramas), distribuídos, em delineamento inteiramente casualizado (DIC), em seis tanques de fibra de vidro, na densidade de 35 peixes tanque -1 em sistema de recirculação contínuo de água. A coleta das fezes foi realizada em sistema de Guelph modificado. Após obtenção dos CDAs, foram formuladas dietas contendo cinco diferentes níveis de inclusão de DDGS (0, 10, 20, 30 e 40%) utilizadas nos ensaios posteriores. O segundo ensaio consistiu na avaliação dos CDAs dos nutrientes das dietas contendo 0, 10, 20, 30 e 40% DDGS, onde juvenis de P. mesopotamicus (27±1.4 gramas) foram distribuídos em cinco tanques de fibra de vidro na densidade de 30 peixes tanque -1 em sistema de recirculação de água. Utilizou-se delineamento em Quadrado Latino, 5x5 (05 dietas e 05 períodos). Concomitantemente ao segundo ensaio, e sob o mesmo sistema de recirculação, juvenis de P. mesopotamicus (21±0.2 gramas) foram distribuídos em 20 tanques de fibra de vidro, na densidade de 15 peixes tanque -1, em DIC, e alimentados com as dietas por 100 dias. Neste terceiro ensaio foram avaliados parâmetros de desempenho produtivo, viabilidade econômica, atividade das enzimas digestivas e de estresse oxidativo do intestino, bem como morfologia intestinal dos juvenis. Os dados obtidos de desempenho produtivo, estresse oxidativo e morfometria intestinal foram submetidos à one-way ANOVA e em caso de significância (p < 0.05) foi realizado teste de Tukey adotandose 5% como nível de probabilidade. Dados de enzimas digestivas foram submetidos a two-way ANOVA e em caso de significância para interação foi feita uma one-way ANOVA e teste Tukey a 5%. Os valores obtidos para os CDA do DDGS confirmaram seu potencial de uso como ingrediente proteico em dietas para P. mesopotamicus, assim como os resultados de desempenho produtivo, onde se obteve menor valor de conversão alimentar e melhor eficiência de retenção de proteína para a dieta contendo maior nível de inclusão de DDGS (40DDGS). Os demais parâmetros de desempenho não foram afetados significativamente. A atividade das enzimas digestivas foi reduzida da porção anterior do intestino para distal e para as dietas com níveis superiores a 10% de DDGS. A inclusão de DDGS levou a redução do status oxidativo do intestino e melhoras na morfometria intestinal. Sendo assim, é possível o uso de até 40% de DDGS do milho como ingrediente proteico em dietas para juvenis de P. mesopotamicus, substituindo em totalidade o farelo de soja, mantendo os valores de desempenho produtivo, melhorando a saúde intestinal dos peixes bem como a capacidade de absorção e aproveitamento dos nutrientes disponibilizados na dieta.
Due to the increased interest in biofuels, Brazilian companies started recently, the production of ethanol from corn, generating a waste with potential for use as an ingredient in animal feed, the DDGS (dried distillers grain with soluble). As its processes results from fermentation of corn grain by yeast and enzymes, this residue has high protein and low soluble carbohydrates, which makes it good source of vegetable protein for animal feed. Besides the low cost, possible benefits related to yeast residues and other enzymes from fermentation may also contribute to DDGS market potential. Thus, this work aimed to evaluate the feasibility of inclusion of corn DDGS in diets for Piaractus mesopotamicus juveniles to replace soybean meal. To this end, there were three experimental runs. In the first assay we evaluated the apparent digestibility coefficients (ADC) of DDGS nutrients for P. mesopotamicus (13 ± 0.3 grams), distributed in a completely randomized design (CRD) in six fiberglass tanks, at density of 35 fish tank-1 in a continuous recirculating water system. The collection of feces was carried out in modified Guelph system. After obtaining the ADCs, diets were formulated with five different levels of DDGS inclusion (0, 10, 20, 30 and 40%) used in subsequent assays. The second test was the evaluation of ADCs of nutrient in the diets containing 0, 10, 20, 30 and 40% DDGS where P. mesopotamicus juvenile (27 ± 1.4 g) were distributed in five fiberglass tanks at density of 30 fish tank-1 in a recirculating water system. We used a Square Latino design, 5x5 (05 diets and 05 periods). Concomitantly to the second test, and under the same recirculation system, P. mesopotamicus juveniles (21 ± 0.2 grams) were divided into 20 fiberglass tanks, at density of 15 fish tank-1 in CRD, and fed diets for 100 days. In this third test were evaluated growth performance, economic viability, activity of digestive enzymes and oxidative stress of the intestine and intestinal morphology of juveniles. Data obtained for growth performance, oxidative stress and intestine morphology were subjected to one-way ANOVA and in case of significance (p <0.05) Tukey's test was carried out adopting a 5% probability level. Data from digestive enzymes were subjected to two-way ANOVA and in case of significance to interaction was made a one-way ANOVA and Tukey's test at 5%. The ADCs values obtained for the DDGS confirmed its potential use as a protein ingredient in diets for P. mesopotamicus, as well as the results of productive performance, which showed lower value of feed conversion ratio and an improved on protein retention efficiency for the diet containing higher inclusion level of DDGS (40DDGS). The other performance parameters were not significantly affected. The activity of the digestive enzymes was reduced from anterior to distal portion of the intestine and for diets with levels above 10% DDGS. The DDGS inclusion led to reduction of oxidative status of the intestine and improvement in intestinal morphology. Thus, the use of up to 40% corn DDGS as a protein ingredient for P. mesopotamicus juvenile is possible, replacing in whole soybean meal, keeping the growth performance, improving fish gut health as well as the absorption and utilization of nutrients available in the diet.

Full textAbstract:
This chapter analyzes the evolution of the energy sector in Brazil, charting shifts in the energy matrix, in particular the rise in renewables and increasing self-sufficiency in fossil fuels. Production of energy in Brazil, particularly electricity, includes a high percentage of renewable sources. Electricity is generated mostly by hydroelectric plants, cars are fueled with ethanol produced from sugarcane, biofuels have good prospects for success, and wind generation of electricity is picking up slowly. The country has managed to become almost self-sufficient in oil production. However, most of the production of energy is in the hands of government institutions, imposing a degree of instability on the system. This chapter has reviewed the effects of some important policies introduced at different points in time. Looking ahead, the chapter concludes that energy policy in Brazil is now moving in the right direction, although significant challenges remain.

Full textAbstract:
The consequences of global warming and the need for a reduction in greenhouse gases have led to dramatic changes in the automotive sector. Whereas the use of biofuel increased continuously over the first decade of this century, e-mobility has been deemed.by politicians and the media alike. As the development of the electric car, rechargeable batteries and charging stations are far from being fully explored, biofuels will play an important role as a bridging technology over the next 20 years. The successful use of biofuels requires its widespread acceptance by consumers. To evaluate the public opinion towards biofuels we carried out a representative opinion poll to collect information on the population’s acceptance of biofuels. The result indicates that there is a lack of interest and information about biofuels, especially among young people and women. First generation bioethanol is strongly associated with the waste of food, but the acceptance of the second generation, produced from agricultural remnants like straw from wheat or corn, is considerably higher. The interviewees see more transparent, objective and less technical information about biofuels as an essential way to increase the level of information and the acceptance rate. In summary, the introduction of biofuels must be accompanied by information campaigns if biofuels should ever reach larger market shares. The irritations caused by the manipulation of the software on the part of several automobile manufacturers of Diesel engines could pave the way for this. So, future decentralized bioethanol plants could play an important role in biofuel production and contribute to the development of rural areas. In this paper the legal aspects of biofuel usage are described, the State of the art Bioethanol production from lignocellulosic material is described, the production capacity worldwide is calculated and the results from an opinion poll concerning the public acceptance of biofuels are presented.

Jet fuels currently in use in the aviation industry are exclusively kerosene-based. However, potential problems regarding security of supply, climate change and increasing cost are becoming more significant, exacerbated by the rapidly growing demand from the aviation sector. Biofuels are considered one of the most suitable alternatives to petrochemical-based fuels in the aviation industry in the short to medium term, since blends of biofuel and kerosene provide a good balance of properties currently required from an aviation fuel. Experimental studies at a variety of stoichiometries using a flat flame burner with kerosene and kerosene/biofuel blends have been performed with product analysis by gas sampling and laser induced fluorescence detection of OH, CO and CO2. These studies have been complemented by modelling using the PREMIX module of Chemkin to provide insights into and to validate combined models describing the oxidation chemistry of surrogate fuels depicting kerosene, fatty acid methyl ester biofuels and Fischer-Tropsch derived fuels. Sensitivity analysis has identified important reactions within these schemes which where appropriate have been investigated by molecular modelling techniques available within GAUSSIAN 03.

Full textAbstract:
Alternative fuels research has been on going for well over many years at a number of institutions. Driven by oil price and consumption, engine emissions and climate change, along with the lack of sustainable fossil fuels, transportation sector has generated an interest in alternative, renewable sources of fuel for internal combustion engines. The focus has ranged from feed stock optimization to engine-out emissions, performance and durability. Biofuels for transportation sector, including alcohols (ethanol, methanol…etc.), biodiesel, and other liquid and gaseous fuels such as methane and hydrogen, have the potential to displace a considerable amount of petroleum-based fuels around the world. First generation biofuels are produced from sugars, starches, or vegetable oils. On the contrary, the second generation biofuels are produced from cellulosic materials, agricultural wastes, switch grasses and algae rather than sugar and starch. By not using food crops, second generation biofuel production is much more sustainable and has a lower impact on food production. Also known as advanced biofuels, the second-generation biofuels are still in the development stage. Combining higher energy yields, lower requirements for fertilizer and land, and the absence of competition with food, second generation biofuels, when available at prices equivalent to petroleum derived products, offer a truly sustainable alternative for transportation fuels. There are main four issues related to alternative fuels: production, transportation, storage, handling and usage. This paper presents a review of recent literature related to the alternative fuels usage and the impact of these fuels on fuel injection systems, and fuel atomization and sprays for both spark-ignition and compression-ignition engines.

The growth of the aviation sector triggered the search for alternative fuels and continued improvements in thecombustion process. This work addresses the technological challenges associated with spray systems and theconcern of mixing biofuels with fossil fuels to produce alternative and more ecological fuels for aviation. This workproposes a new injector design based on sprays produced from the simultaneous impact of multiple jets, using anadditional jet of air to assist the atomization process. The results evidence the ability to control the average dropsize through the air-mass flow rate. Depending on the air-mass flow rate there is a transition between atomizationby hydrodynamic breakup of the liquid sheet formed on the impact point, to an aerodynamic breakup mechanism,as found in the atomization of inclined jets under cross-flow conditions. The aerodynamic shear breakupdeteriorates the atomization performance, but within the same order of magnitude. Finally, our experiments showthat mixing a biofuel with a fossil fuel does not significantly alter the spray characteristics, regarded as a stepfurther in developing alternative and more ecological fuels for aero-engines.DOI: http://dx.doi.org/10.4995/ILASS2017.2017.4737

Palm methyl ester (PME) is a renewable biofuel that is produced by the transesterification of palm oil; it is a popular alternative fuel used in the transportation sector. The objective of this investigation was to study the combustion characteristics of flames of pre-vaporized diesel and PME in a laminar flame environment at initial equivalence ratios of 2, 3 and 7 and to isolate the factors attributable to chemical structure of the fuel. The equivalence ratio was changed by altering the fuel flow rate, while maintaining the air flow rate constant. The global CO emission index of the PME flames was significantly lower than that of the diesel flames; however, the global NO emission index was comparable. The radiative fraction of heat release and the soot volume fraction were lower for the PME flames compared to the diesel flames. The peak temperatures were comparable at an equivalence ratio of 2, but at higher equivalence ratios, the peak temperatures in the PME flames were higher. The measurements highlight the differences in the combustion properties of biofuels and petroleum fuels and the coupling effects of equivalence ratio.

Abstract The world greatly relies on the usage of liquid fuels for its energy needs, especially in the transportation sector, which is very high in developing countries. In countries like India, diesel fuel is mainly used for all its transportation requirements (considering its higher efficiency), leading to higher pollution. Many kinds of research works are conducted to find a replacement for diesel fuel. In which biodiesel is considered to be a potential replacement for diesel. However, the challenges like higher viscosity, lower calorific value, higher NOx emission stands as a huge barrier. To overcome this, this study proposes using a low viscous biofuel, which has a higher calorific value close to diesel. To reduce NOx emission, the exhaust gas recirculation (EGR) technique is used in this study. A single-cylinder, constant speed, water-cooled stationary engine setup is used for this study. 20% of pine oil is blended with diesel, and 10ml of 1,4, dioxane additive is added. These blends are tested in the engine for different load conditions (0, 25, 50, 75 and 100%) with and without 10% EGR. The results showed that pine oil usage negatively affected the performance characters but significantly reduced CO, HC, and Smoke emissions (15.94, 17.04 and 2.47% respectively). The 10ml of 1,4, dioxane further enhanced this reduction (32.61, 28.15 and 4.36% respectively). The 10% EGR usage negatively affected both performance and emission characters, but it reduced NOx emissions significantly (11.53%). This study provides an integrated way to overcome the challenges seen in biodiesel usage with a low viscous biofuel and exhaust gas recirculation technique.

Transportation fuels are heavily dominated by the use of petroleum, but concerns over oil depletion (e.g., peak oil), energy security, and greenhouse gas emissions from petroleum combustion are driving the search for alternatives. As we look to shift away from petroleum-based transportation fuels, most options consume and withdraw more water during their life cycle. Thus, shifting to alternative fuel and energy supplies for transportation will likely increase water use for the transportation sector. Previous work suggests that water consumption for transportation could reach 10% of total U.S. water consumption when meeting the Federal Renewable Fuels Standard mandate at modest irrigation levels for feedstock crops (corn, cellulosic grasses) in combination with other alternative fuels and vehicle technologies (electric vehicles, natural gas vehicles, etc.), but more refined analysis is needed. It is important to understand when and where these new water demands for transportation are anticipated to occur. This paper presents results from simulations of the U.S. 9-region (EPAUS9r) MARKAL (MARKet ALlocation) integrated energy systems model for mapping the changes in water withdrawal and consumption during a transition to a low carbon-emitting U.S. transportation fleet. The advantage of using a bottom-up, multi-sector model like MARKAL is the ability to look at consistent scenarios for the full energy system, and endogenously capture interactions between different sectors (e.g. electric power production, biorefineries, and the LDV fleet). MARKAL can simulate a baseline scenario driven by assumptions for biomass feedstock and fossil resource costs and availability, as well as the costs of converting those resources to liquid fuels and electricity. We investigate alternative scenarios both with and without carbon constraints, while varying the pace of vehicle electrification. We compare these scenarios to assess regional differences in water needs as well as aggregate water demand for transportation energy, and how those trade off against greenhouse gas emissions reductions. Our results indicate that the regional water demands and interregional transfers of embodied water could be significant as the light-duty vehicle fleet moves away from petroleum-based fuels, with exports of embodied water on the order of hundreds of billion gallons of water per year for ethanol coming from the Midwest. Interregional transfers of water embodied in electricity may also reach tens of billion gallons of water per year. However, these water requirements will vary substantially based on the light-duty vehicle mix, carbon policy, electric power generation mix, biofuel production levels, and feedstock characteristics.

Current US transportation sector mainly relies on liquid hydrocarbon derived from petroleum and about 60% of the petroleum consumed is from areas where supply may be disturbed by regional instability. This has led to serious concerns on global warming and energy security. To address these issues, numerous alternative energy carriers have been proposed. Among them, second generation biofuel is one of the most promising technologies. Gasification based thermo-chemical conversion can utilize a wide range of biomass wastes and residues and bring flexibility to both feedstock and production sides of a plan. Thus it presents an attractive technical route. In this paper, a flexible feedstock thermo-chemical ethanol production process is investigated. This research focuses mainly on the evaluation of the feasibility of the process through numerical simulation. An existing thermo-chemical ethanol production model developed by NREL has been updated to handle the cases when different biomass feedstock and feedstock combinations are used. It is found that the ethanol yield is positively linear proportional to the feedstock feeding rate, while the total conversion efficiency is negatively proportional to the feeding rate. To demonstrate a feedstock management strategy, a plant located near a major city with a population of 200,000 and above is considered and MSW, corn stover and wood chips are selected as potential feedstock. Simulation results indicate that with wood chips as the backup feedstock the plant can be operated under extreme conditions when corn stover availability is significantly reduced without major equipment modification.
