Resumo: Com a primeira crise do petróleo, em 1973, houve necessidade de buscar fontes alternativas de energia que pudessem substituir os derivados de petróleo. Assim, o Programa Nacional do Álcool ¿ ProÁlcool foi instituído com a emissão do Decreto nº 76.593, de 14 de novembro de 1975, baseando-se, inicialmente, na produção de álcool anídro para misturá-lo à gasolina. Com a nova crise do petróleo, em 1979, além da mistura à gasolina, iniciou-se a fabricação de automóveis movidos a álcool. Isto intensificou a agroindústria canavieira, responsável por impactos ambientais como a destruição de áreas com mata nativa, perda da diversidade da produção rural e lançamento de vinhaça nos rios. Ainda hoje, tais impactos geram problemas ambientais e sociais como: erosão e poluição dos solos, poluição dos recursos hídricos por agrotóxicos, emissão de poluentes na atmosfera pela queima dos canaviais, destruição da biodiversidade e aumento do êxodo rural. Como contrapartida positiva, a adoção do álcool combustível melhorou a qualidade do ar nas cidades brasileiras, substituindo substâncias tóxicas nos combustíveis de veículos automotores. Assim, a relação custo/benefício merece um estudo aprimorado, uma vez que esta indústria é afetada pelas novas possibilidades tecnológicas. Este trabalho analisa possibilidades alternativas da produção da cana-de-açúcar e fabricação de açúcar e álcool, agrupadas como tendências que podem melhorar a produção e diminuir os impactos ambientais da atividade canavieira. Entre elas destacam-se aquelas relacionadas às disposições legais, às inovações tecnológicas e às forças de mercado. A análise da produção da cana, do açúcar e do álcool baseou-se em dados coletados em usinas do estado de São Paulo e, a partir destes dados, foi verificado como a aplicação destas tendências afetaria a agroindústria. A ferramenta escolhida para realizar esta análise foi à metodologia emergética, que permite avaliar os impactos ambientais do sistema de produção, verificando os índices relacionados ao uso de recursos renováveis e não renováveis, os serviços ambientais locais, os serviços econômicos e a rentabilidade econômica do sistema. Baseando-se na metodologia, as vantagens e desvantagens de cada tendência foram identificadas de acordo com o aproveitamento dos recursos naturais renováveis e não-renováveis, materiais e serviços. Das tendências analisadas, a que obteve melhores índices foi a agricultura orgânica. Como previsto, esta técnica aproveita melhor os recursos naturais, agredindo menos o solo e o meio ambiente. Outra vantagem verificada foi à necessidade intensiva de mão-de-obra rural. Esta técnica oferece benefícios ambientais, por ser menos poluidora, e benefícios sociais, pois mantém o emprego dos trabalhadores rurais. Por outro lado, a que se mostrou menos sustentável foi à mecanização da colheita, devido à necessidade de maiores investimentos em equipamentos, tecnologia e combustíveis. É importante ressaltar que cada tendência foi estudada isoladamente, sendo importante realizar simulações com duas ou mais tendências. Com a incorporação de mais tendências na mesma atividade os impactos ambientais e sociais tendem a diminuir, melhorando a produtividade da agroindústria canavieira
Abstract: With the first crisis of the oil, in 1973, it had necessity to search alternative energy sources that could substitute the oil derivatives. Thus, the Alcohol National Program ¿ ProÁlcool ¿ was instituted with the emission of the Decree n° 76,593, of November 14, 1975, being based, initially, in the anhydrous alcohol production to be mixed to gasoline. With the new crisis of the oil, in 1979, beyond the mixture to the gasoline, it was initiated the manufacture of automobiles moved by alcohol. This intensified the sugar cane agricultural industry, responsible for environmental impacts such as the destruction of areas with native forest, loss of the agricultural production diversity and launching of vinasse in the rivers. Still today, these impacts generate environmental and social problems such as: ground erosion and pollution, pollution of the hydro resources with pesticides, pollutants emission in the atmosphere with the cane-plantation burning, biodiversity destruction and increase of the agricultural exodus. As positive counterpart, the adoption of the combustible alcohol improved the quality of air in the Brazilian cities, substituting toxic substances in automachine vehicles fuels. Thus, the cost/benefit relation deserves an improved study, because this industry is affected by the new technological possibilities. This work analyzes alternative possibilities of the sugar cane production and sugar and alcohol manufacture, grouped as trends that can improve the production and diminish the environmental impacts of the sugar cane industry activity. Among them those related to the legal disposals, to the technological innovations and to the market forces are distinguished. The analysis of the sugar cane, sugar and alcohol production was based on data collected in industries in the state of São Paulo and, from these data, it was verified how the application of these trends would affect the agricultural industry. The chosen tool to carry through this analysis was the emergy methodology, that allows the evaluation of the environmental impacts of the system production, verifying the index related to the utilization of renewable and non-renewable resources, the local environmental services, the economic services and the economic yield of the system. Being based on the methodology, the advantages and disadvantages of each trend had been identified in accordance with the exploitation of the renewable and non-renewable natural resources, materials and services. In the analyzed trends, the one that got better index was the organic agriculture. As foreseen, this technique takes advantage of the natural resources better, attacking little the ground and the environment. Another verified advantage was the intensive necessity of agricultural manpower. This technique offers environmental benefits, for being less polluting, and social benefits, because it keeps the job of the agricultural workers. On the other hand, the one that showed less sustainability was the harvest mechanization, due to necessity of bigger investments in equipment, technology and fuels. It is important to stand out that each trend was studied separately, being important to carry through simulation with two or more trends. With the incorporation of more trends in the same activity the environmental and social impacts tend to diminish, improving the productivity of the sugar cane industry

Full textCuba is currently highly dependent on imported oil, mainly from Venezuela, to meet their growing electricity demand. This dependence makes Cuba sensitive to changes in oil price as well as the political climate. The current crisis in Venezuela has a large impact on Cuba’s electricity generation. By expanding its renewable energy sources Cuba could decrease their dependence on other countries and diversify their energy supply. Moreover, it would have a positive climate impact by reducing the country’s CO2-emissions. Geographically, Cuba has ideal conditions for renewable energy utilization, such as solar power. Solar energy is constantly progressing and is considered a great source of energy. Concentrating Solar Power (CSP) is a technology which applies mirrors and/or lenses to concentrate the sunlight onto a small area which converts the sunlight into heat, possible to use in a thermodynamic cycle. There are mainly two problems with the implementation of CSP in Cuba. Firstly, CSP is a non-dispatchable power generating system since it is dependent on the instantaneous weather conditions. Secondly, it has high investment costs. One way of solving these problems is by implementation CSP in an already existing power plants with a dispatchable source of energy, making it a hybrid power plant. Accordingly, the hybrid power plant would be dispatchable and the investment costs would be significantly lower. Existing power plants can be found in Cuban sugar mills. This study investigates the possibility to implement solar power in the sugar mill Carlos Baliño, located in Villa Clara, Cuba. The factory is currently self-sufficient electricity wise on a yearly basis, using a co-generation Rankine cycle to generate electricity and process heat used in the sugar production. The fuel used is bagasse, a rest product obtained after the sugar juice has been pressed out of the sugar canes. Four CSP-technologies and three implementation layouts were examined, resulting in the parabolic trough-technology and feedwater heating being considered the optimal solution. Furthermore, two different scenarios for CSP was investigated; implementation of CSP in the mill at the current state (scenario 1) or after investing in a Condensing-Extraction Turbine (CEST) (scenario 2). The results show that Carlos Baliño should invest in a CEST before considering implementation of CSP. Off-season operation is not available for scenario 1, leading to a vast amount of solar potential being unexploited. The maximal investment allowed for scenario 1 is 3.7 MUSD, which is not a realistic number. The maximal investment allowed for in scenario 2 is 5.9 – 7.2 MUSD, depending on bagasse import availability. If bagasse import is unlimited, it is not recommended to invest in solar power. Implementation of CSP in scenario 2 regarding bagasse import limits would yearly lead to an additional electricity generation at Carlos Baliño of 5.4 – 7.3 GWh, decrease the oil usage with 16,100 – 21,800 barrels and the CO2-emissons with 1,200 – 1,600 tonnes. Carlos Baliño’s annual yield would increase with 0.5 – 0.6 MUSD/year and the Cuban states annual yield would increase with 0.7 – 0.9 MUSD/year. Future work is recommended to explore alternatives to all year-around electricity generation in Carlos Baliño without investing in a CEST, investigate solar power demand on a national level, and examine possible developments of the suggested solar field, for instance solar-only operation.

Full textThe Sugar Industry in Fiji is facing a lot of problems. Since the Government of Fiji has not fulfilled their commitments to the European Union (EU), the EU has backed away from supporting the industry. The milling efficiency has been constantly declining since the mid 1980’s and farm productivities have not kept pace with the changing international market for sugar. To be able to obtain the economies of scale, the sugar production in Fiji has to increase with 75 % from the current level of production. A lot of towns in Fiji would be nothing without the Sugar Industry, and thousands of people are dependent on the industry for their sustenance. Due to this fact, it is certain that the loss of confidence in the industry, or any likely collapse, would imply disaster for Fiji as a whole. It will lead to serious implications on the economic, social and political stability of Fiji.
The overall aim of this thesis is to study the effects of the EU measures especially on the Sugar Industry in Fiji, to be able to understand to which extent the industry depends on the support from the EU. The aim is also to analyse and discuss different competition strategies on how Fiji can compete and be a part of the global market of sugar.
This research was made from a qualitative approach in order to gain a deeper understanding about the problem. Abduction made it possible to work parallel with different parts of the thesis. A combination of primary and secondary data gathering has been used, with the secondary data as a basis for building the empirical part of the thesis. The primary data was collected through in-depth interviews with people at different positions within the Sugar Industry in Fiji.
Fiji is dependent on the Sugar Industry and since there is no other obvious donor for Fiji today, and it is crucial that the industry gets support, the conclusion is that Fiji also is dependent on the support from the EU. Even though Fiji has the possibility to increase their competitiveness on the regional as well as on the international market, there is no need for Fiji to strive after the world market at the moment.

Full textDie voormalige minister van finansies het in sy begrotingstoespraak in 2016 vermeld dat suikerbelasting vanaf 1 April 2017 in Suid-Afrika in werking gaan tree. Die tesourie se rede vir die implementering van suikerbelasting is om, in samewerking met die Departement van Gesondheid, die gesondheidsprobleme wat deur suiker veroorsaak word te verminder. Dit is niks nuuts om fiskale maatstawwe te gebruik om beide belasting in te vorder en gesondheidsprobleme te voorkom nie, maar dit was nog nie moontlik om tot ’n definitiewe gevolgtrekking te kom oor die impak van suikerbelasting op die verbruik van suikerversoete drankies en die voorkoms van vetsug nie. Die rede hiervoor is dat daar bewyse is dat die implementering van voedselbelasting in verskillende lande verskillende resultate getoon het in terme van openbare gesondheidskwessies en belastingvoordele. In Suid-Afrika kan die implementering van suikerbelasting óf die voorkoms van vetsug verminder en sodoende die ekonomie bevoordeel óf die implementering daarvan kan die ekonomie negatief beïnvloed. Indien die tesourie nie suikerbelasting implementeer nie kan die ekonomie as gevolg van die voorkoms van vetsug negatief beïnvloed word. Die kern van hierdie skripsie handel oor die gevolge van nieoordraagbare siektes en suikerbelasting op die Suid-Afrikaanse ekonomie. Daar word spesifiek gefokus op hoe suikerbelasting internasionaal geïmplementeer word en hoe Suid-Afrika beoog om suikerbelasting te implementeer.

Globalization has transformed the markets in which agricultural goods are traded, placing new demands on farmers around the world. In developing countries, smallholder and peasant farmers lack many of the resources needed to upgrade their production capacities and meet new global quality standards, making them vulnerable to marginalization and exploitation. This dissertation seeks to discover the conditions that permit smallholders to upgrade in global value chains while also enhancing the voice and autonomy they exercise within their communities. To do so, it examines global niche markets for environmentally and socially responsible products. Organic agriculture favors smallholders' labor-intensive production, and Fairtrade certification explicitly attempts to leverage globalization for smallholder development. Paraguay's smallholder sugarcane farmers have been the unlikely beneficiaries of these new global market niches, as the world's largest exporters of Fairtrade and organic sugar. Two Paraguayan cane farmer organizations share similar socio-economic characteristics but have had varied success in taking advantage of Fairtrade's upgrading resources. To explain the variation between these two cases and to describe the conditions that favor smallholders' success in global niche markets, this dissertation puts forward the concept of a clientelist production network: the set of unequal social and political relationships that structure economic exchanges between farmers organizations, their leaders, and the buyers or processors that serve as their patrons. I also point out the role brokers play as "switches" for collective action and upgrading within clientelist networks. Under pluralistic clientelism multiple brokers compete with one another and are more likely to mobilize farmers collectively. This permits farmers to build new commercial and institutional relationships and to improve the accountability of their organizations, creating a basis for autonomous upgrading in global value chains. Under monopolistic clientelism farmer groups depend on a single broker. This makes brokers more likely to support a process of dependent upgrading, in which farmers confront new production costs but are less likely to enhance their share value added, to elicit greater accountability from their leaders, or to increase their autonomy from the buyers or processors that serve as their patrons.

Full textBiosurfactants are compounds with surface activity constituting the major class of natural surfactants that present interesting features (e.g. emulsifying capacity) for the food industry. These compounds have several advantages over synthetic surfactants such as degradability, can be synthesized from renewable substrates as carbohydrates and fatty acids, and low toxicity. In this sense, the purpose of this thesis is to synthesize new biosurfactants, in particular fructose, sucrose and lactose esters, for potential use in the food industry. Several synthesis experiments were performed under different experimental conditions to maximize the esterification reaction yield, and consequently the production of biosurfactant. The sugar ester biosurfactants purity was the determinant factor for these studies. The synthesis assays were performed in shake flasks under controlled temperature, time and agitation, according to the optimal criteria for the lipases used, namely Candida antarctica type B (CALB) lipase and porcine pancreas lipase (PPL). An experimental design was conducted in order to optimize the yield of fructose esters production from fructose, oleic acid and ethanol using CALB. Temperature and reaction time were found to be the most significant parameters. The optimum conditions were 57.1 ºC, 100 rpm and 37.8 h and a maximum esterification yield of 88.4% was obtained. Afterwards, the lipases from CALB and PPL were used with different carbohydrates (fructose, sucrose and lactose), fatty acids (oleic and linoleic) and solvents (ethanol and ethyl acetate), in order to explore the synthesis of novel sugar esters with improved characteristics. The optimal conditions have been established for all set of experiments and the sugar ester biosurfactants have been characterized according to their surface activity and emulsification index (EI). In the experiments for which CALB was used, lactose ester synthesized using linoleic acid and ethanol presented the highest esterification yield (83.5%). However, the fructose esters obtained showed a better performance regarding their ability to reduce surface tension (35.8 mN/m) and to stabilize an emulsion (EI between 54.4 and 58.4%). Regarding the use of PPL, the highest esterification yields (47.6%) were observed for sucrose esters, which presented the best reduction of surface tension (33.4 mN/m) and EI (between 58.1 and 58.4%). Finally, CALB was immobilized on chitosan and used to synthesize sugar ester biosurfactants. The enzyme immobilization on chitosan showed the highest yield in the lactose ester production (84.1%) compared with the results obtained with the lipase CALB immobilized on acrylic resin. Additionally, the production of fructose ester was found to be higher for CALB immobilized on acrylic resin (74.3%). Sugar ester biosurfactants were then added to samples of fresh coconut milk and characterized according to their surface activity, EI and particle size distribution. Results indicated the lactose ester as the best biosurfactant (surface tension reduction 38.0 mN/m, EI = 54.1%), although good results were also found for the other sugar esters. In summary, the results gathered in this thesis demonstrate the potential of sugar ester biosurfactants for food industry applications.
Biosurfactantes são compostos com actividade de superfície que constituem a principal classe de surfactantes naturais e que apresentam características interessantes (por exemplo, capacidade emulsificante) para a indústria alimentar. Estes compostos têm várias vantagens sobre os surfactantes sintéticos, são biodegradáveis, podem ser sintetizados a partir de substratos renováveis tais como os carboidratos e ácidos graxos, e têm baixa toxicidade. Nesse sentido, o objectivo desta tese é sintetizar novos biosurfactantes, em particular os ésteres de frutose, sacarose e lactose, para potencial uso na indústria de alimentos. Vários experimentos de síntese foram realizados sob diferentes condições experimentais para maximizar o rendimento da reacção de esterificação e, consequentemente, a produção de biosurfactantes. A pureza dos ésteres de açúcar biosurfactantes foi o factor determinante para esses estudos. Os ensaios de síntese foram realizados em matraz sob condições controladas de temperatura, tempo e agitação, de acordo com os critérios óptimos para as lipases utilizadas, nomeadamente a lipase Candida antarctica tipo B (CALB) e lipase pâncreas de porco (PPL). Um delineamento experimental foi conduzido de forma a optimizar o rendimento da produção de ésteres de frutose a partir de frutose, ácido oléico e etanol utilizando CALB. A temperatura e o tempo de reacção foram considerados os parâmetros mais significativos. As condições óptimas foram 57.1 ºC, 100 rpm e 37.8 h e um rendimento máximo de esterificação de 88.4% foi obtido. Posteriormente, as lipases CALB e PPL foram utilizadas com diferentes carboidratos (frutose, sacarose e lactose), ácidos graxos (oléico e linoléico) e solventes (etanol e acetato de etila), a fim de explorar a síntese de novos ésteres de açúcar com características melhoradas. As condições óptimas foram estabelecidas para todo o conjunto de experimentos e os ésteres de açúcar biosurfactantes foram caracterizados de acordo com sua actividade superficial e índice de emulsificação (IE). Nos experimentos onde a lipase CALB foi utilizada, o éster de lactose sintetizado usando ácido linoléico e etanol apresentou o maior rendimento de esterificação (83.5%). No entanto, os ésteres de frutose obtidos mostraram melhor desempenho quanto à capacidade de reduzir a tensão superficial (35.8 mN/m) e para estabilidade da emulsão (EI entre 54.4 e 58.4%). Quanto ao uso da PPL, o maior rendimento de esterificação (47.6%) foi observado nos ésteres de sacarose, que apresentaram a melhor redução de tensão superficial (33.4 mN/m) e EI (entre 58.1 e 58.4%). Finalmente, a lipase CALB foi imobilizada em quitosana e usada para sintetizar ésteres de açúcar biosurfactantes. A imobilização da enzima em quitosana apresentou o maior rendimento na produção de éster de lactose (84.1%) em comparação com os resultados obtidos com a lipase CALB imobilizada em resina acrílica. Além disso, a produção de éster de frutose foi maior com a lipase CALB imobilizada em resina acrílica (74.3%). Em seguida, ésteres de açúcar biosurfactantes foram adicionados às amostras de leite de coco fresco e caracterizadas de acordo com sua actividade superficial, EI e distribuição do tamanho das partículas. Os resultados indicaram o éster de lactose como o melhor biosurfactante (tensão superficial 38.0 mN/m, EI = 54.1%), embora bons resultados também foram encontrados para os outros ésteres de açúcar. Em resumo, os resultados obtidos nesta tese demonstraram o potencial dos ésteres de açúcar biosurfactantes para aplicações na indústria alimentar.
