No. of bitstreams: 1 2017 - Walciney Jos? das Chagas de Oliveira.pdf: 2552173 bytes, checksum: b5ff12c05946a53ec0cc884a550f3d22 (MD5) Previous issue date: 2017-02-23 / AusAID (Australian Agency for International Development, Austr?lia) / Whey produced by small to medium cheese makers in the state of Minas Gerais is currently being underutilised and carries an economic burden due to losses to the environment. The current study provides a diagnostic of whey utilisation in a selected cluster of 76 dairy companies located in Zona da Mata and Campo das Vertentes and economically assesses potential value addition scenarios for regional development by considering the potential whey uptake by two established drying plants with spare capacity. The decision making model indicated that the most economical scenario includes the installation of whey collection centers. With a minimum regional development investment of R$55,000,000.00, the model selects the Ponte Nova plant as the recipient of the cluster?s whey (mostly in pre-concentrated form) to produce partially demineralised whey powder 40%, with a return of investment of 2.9 years. Changes in transportation costs did not impact on the model output recommendations. This study demonstrated the economic viability for whey recovery into whey powder following the formation of a cluster of associated small to medium cheesemakers. / O soro de leite produzido por pequenas e m?dias queijarias em Minas Gerais est? sendo subutilizado e carrega um fardo econ?mico devido a perdas para o meio ambiente. O presente estudo fornece um diagn?stico da utiliza??o de soro de leite em um cluster selecionado de 76 latic?nios localizados na Zona da Mata e Campo das Vertentes, e economicamente avalia poss?veis cen?rios de agrega??o de valor para o desenvolvimento Regional, considerando a absor??o de soro de leite potencial por duas plantas de secagens estabelecidas com capacidades ociosas. O modelo de tomada de decis?o indicou que o cen?rio mais econ?mico inclui a instala??o de centro de coletas de soro de leite. Com um investimento de desenvolvimento Regional m?nimo de R$ 55.000.000,00, o modelo seleciona a planta de Ponte Nova como o destinat?rio do soro do cluster (principalmente na forma de pr?-concentrado) para produzir o soro de leite parcialmente desmineralizado em p? 40%, com um retorno do investimento de 2,9 anos. Mudan?as nos custos de transporte n?o impactaram as recomenda??es de sa?da do modelo. Este estudo demonstrou a viabilidade econ?mica para a recupera??o do soro de leite em soro em p? ap?s a forma??o de um cluster de pequenos e m?dios associados queijeiros.
