Zimmermann, Haidi Andiara January 2008 (has links)
As rápidas e abrangentes mudanças nos mercados mundiais e regionais de vinhos, com significativos impactos sobre algumas vinícolas, estimularam a realização deste estudo. O objetivo central é analisar as exportações de vinhos brasileiros pós-plano real, a atuação das empresas vinícolas no mercado internacional de vinhos bem como as estratégias e perspectivas do setor. A globalização e a formação de novos mercados como o Mercado Comum do Sul (Mercosul), União Européia e ALCA, afetaram, de forma direta ou indireta, as estratégias do setor. As ações estratégicas também foram moldadas e seus retornos influenciados pelo ambiente e cultura do país. Com relação ao conteúdo das estratégias, cabe ressaltar que as estratégias de produtos e produção tiveram comportamento semelhante em todas as vinícolas participantes da pesquisa; quanto às alianças estratégicas, constata-se que oito delas realizaram algum tipo de aliança. Também foi possível detectar que todas as estratégias estão inter-relacionadas, tendo em vista os objetivos do setor de vinhos. Pôde-se concluir que, o setor está em processo de implementação do Plano de Desenvolvimento Estratégico “Visão 2025”. / The fast and wide-ranging changes in wine local and world market as well as its significant impact on some wineries, have encouraged this study. The main objective is the analysis on exports of Brazilian wines after the so called ‘Plano Real’, the government’s economical-financial plan, the analysis of performances on international wine markets, strategies and perspectives for the sector. Globalization and formation of new markets as the Mercosul - Southern Common Market, EU - European Union and, FTTS, Free Trade Area of Americas have directly or indirectly affected strategies on the sector. Strategical actions have also been adapted and its incomes influenced by the environment and culture of the country. About the contents of strategies it is worth mentioning that strategies for products and production were similar in all wineries. As for strategical alliances, eight of the wineries have taken part on any. It was also possible to detect that all the strategies are inter-related, given the objectives of the wine sector. We could conclude that the sector is implementing the Strategical Development Plan ‘Visão 2025’ which is being elaborated by the winery sector.

What is the price of quality? : Investigating the effect of increased wine quality on the price of a wine and how it may differ between a monopolised and a non-monopolised alcohol market.

Nyblom, Jakob January 2018 (has links)
The purpose of this paper is to investigate the effect of an increased wine quality on the price of a wine and how this may differ between a country with a monopolized alcohol market and one that has not. The main reason for this comparison is to analyse whether the politics of the Swedish alcohol monopoly have succeeded in premiering quality over quantity drinking and if that has created possibilities for arbitrage trading of wine. Data regarding the price of wines was gathered from the Swedish alcohol monopoly’s website and VildMedVin, the largest e-commerce for wine in Denmark. One of the largest wine reviewers in the world, Wine Spectator, utilises a 1-100 scale when rating wines; this is used as a proxy for quality. By creating four different regression models it was found  that when it comes to wines that are more expensive than 99 SEK, there is no  statistically significant difference in the effect of quality on the price of a wine between Sweden and Denmark. Indicating that the law of one price might be what denies the possibility of arbitrage between a monopolised and a non-monopolised market is non- existent. There is, however, a general effect in both countries, an increase in quality by 1 unit is associated with an increase in the wine’s price by approximately 8%.

Tratamento físico-químico em efluente de vinícola de pequeno porte

Lechinhoski, Maryelen 15 July 2015 (has links)
Os efluentes vinícolas apresentam concentração de matéria orgânica que varia entre 1.200 mg.L-1 a 92.000 mg.L-1 de DQO. O pH é ácido, variando entre 3,5 a 5,0. A concentração de compostos fenólicos varia entre 41 a 1450 mg.L-1 C6H5OH. Para nitrogênio amoniacal a concentração varia entre 12 a 208 mg.L-1 já para sulfetos entre 50 e 500 mg.L-1S. Com base nestas informações, foi proposto um sistema de tratamento de efluentes físico-químico em batelada, composto por oxidação avançada do tipo Fenton e duas colunas de adsorção preenchidas com adsorventes alternativos: uma com resíduos de olarias (restos de cerâmicas) e outra com resíduos sólidos da construção civil (britados em recicladora). O efluente vinícola foi caracterizado através dos seguintes parâmetros: pH, turbidez, DQO, sólidos, nitrogênio, fósforo e fenol total. Os materiais adsorventes citados foram comparados ao adsorvente convencional, carvão ativado, e caracterizados no que diz respeito a: pH, densidade aparente e relativa, teor de umidade, teor de material volátil e teor de cinzas. No ensaio final para a oxidação do efluente bruto, foi aplicada a concentração de peróxido de hidrogênio de 16 g.L-1 na relação com a H2O2/DQO denominada de “z” igual a 3,36, o catalisador da reação foi o sulfato ferroso na proporção de 1:15 (FeSO4.7H2O:H2O2). O tempo de reação foi de quatro horas a 30°C em mesa agitadora a 150 rpm. Após a oxidação por Fenton, o efluente foi submetido à adsorção em coluna de cerâmica na taxa de 5m3.m2.dia-1, sequencialmente o efluente foi inserido na coluna de resíduos sólidos da construção civil na taxa de aplicação de 4 m3.m2.dia-1. O desempenho do sistema foi avaliado em função de DQO, turbidez, nitrogênio, sólidos, fenol total e cor. Ao final do tratamento a eficiência na remoção de DQO foi de 92,25%, atingindo valores de DQO de 369 mg.L-1. Além disso, o sistema de tratamento aplicado se apresentou eficaz na remoção da cor (100%), fenol total (100%), turbidez (100%), sulfatos (98%) atingindo uma concentração de 40,5 mg.L-1, nitrogênio (10%) com 17,25 mg.L-1 e na remoção de sólidos: ST (95% com 2,29 mg.L-1), STF (71% com 0,92 mg.L-1), STV (97% com 1,37 mg.L-1), SST (95% com 0,08 mg.L-1), SSF (96% com 0,01 mg.L-1), SSV (91% com 0,09 mg.L-1), SDT (95% com 2,21 mg.L-1), SDF (67% com 0,9 mg.L-1) e SDV (97% com 1,27 mg.L-1). A vantagem da aplicação de Fenton no efluente bruto consistiu em aproveitar as características ácidas do efluente, condição necessária para que o sulfato de ferro não precipitasse, exercendo assim a função de catalisador da reação. Posteriormente a oxidação, foi necessário neutralizar o pH para precipitação do ferro, condição que ocorreu nas colunas de adsorção com os resíduos sólidos da construção civil, possibilitando a precipitação, filtração e remoção do ferro. A combinação deste sistema facilitou e minimizou o uso de reagentes químicos, possibilitando a aplicação prática em vinícolas de produção sazonal e que não possui grandes áreas para a instalação de sistemas maiores e mais complexos. Conclui-se que, o sistema físico-químico proposto apresenta relevante eficiência quanto à remoção de matéria orgânica, cor, sólidos, nitrogênio, sulfatos e fenol total, possibilitando a disposição em corpos hídricos ou rede pública de esgoto. / The organic matter present on those winery effluents varies from 1.200 mg.L-1 to 92.000 mg.L-1 of COD. The pH is acidic, varying from 3,5 to 5,0. The concentration of phenolic compounds ranges between 41 to 1450 mg.L-1 C6H5OH . For ammonia the concentration varies from 12 to 208 mg.L-1. Sulfates have to between 50 and 500 mg.L-1 S. Based on these information, a physical-chemical treatment system was proposed, analyzed into batches, which consisted of the advanced Fenton ́s Oxidation and two adsorption columns filled with alternated adsorbents: one with pottery residues and the other with residues from building (concrete) sites ( crushed on crushing machines). The winery effluent characterization was establish according to the following parameters: pH, turbidity, COD, solids, nitrogen, phosphate and phenols. The absorbents resources were characterize pH, bulk and relative densities, moisture content, volatile material, ash content. The assays begun with the oxidation of the raw effluent, followed by the addition of 16 g.L-1 of hydrogen peroxide related to a COD of z=3,36 (H2O2/DQO). Ferrous sulfate catalyzed the reaction at 1:15 portion (FeSO4.7H2O:H2O2), on an agitated platform at 150 rpm for four hours at 30oC. Once Fenton’s oxidation was concluded, the effluent was applied to the pottery absorption column, at 5m3/m2.day-1, and subsequently applied to the building sites residues column at 4m3/m2.day-1. The system’s performance was evaluate according to the COD, turbidity, nitrogen, solids, phenols and color. The COD efficiency removal obtained was 92,25%, reaching COD values of 369 mg.L-1. In addition, the chosen applied treatment revealed to be efficient on the elimination of color (100%), phenols (100%), turbidity (100%), sulfates (98%) reaching a concentration of 40.5 mg.L-1, nitrogen (10%) with 17.25 mg.L-1, and on solids removals: ST (95% with values of 2,29 mg.L-1), STF (71% and 0,92 mg.L-1), STV (97% and 1,37 mg.L-1), SST (95% and 0,08 mg.L-1), SSF (96% and 0,01 mg.L-1), SSV (91% and 0,09 mg.L-1), SDT (95% and 2,21 mg.L-1), SDF (67% and 0,9 mg.L-1) e SDV (97% and 1,27 mg.L-1). The advantage of the Fenton application on the raw effluent consisted on taking benefit of the acidic environment of the effluent, environment that gave the right condition to avoid the precipitation of the iron sulfate, becoming the reaction catalyst. Once the oxidation was completed, it was necessary to neutralize de pH to allow the iron precipitation, which took place into the building residues adsorption columns, allowing iron the precipitation, filtration and removal. These methods combined enabled and minimized the use of chemical reagents, allowing it to be easily mounted in wineries with seasonality production and wineries without a large area to install bigger and more complex systems. In conclusion, the physical – chemical system proposed revealed to be efficient on the removal of the organic mass, colors, solids, nitrogen, sulfates and phenols, allowing the discharge of effluent disposal.
