Abstract(s)
Na atualidade, observa-se uma crescente valorização dos mercados na atribuição de um rótulo ecológico aos produtos. Tendo em conta que todos possuem um impacto ambiental associado à sua produção, torna-se fundamental analisar todos os processos de produção para uma melhor perceção dos impactos de cada um.
No presente estudo são analisados os impactos ambientais de um produto regional, o Queijo da Beira Baixa, sendo esta a maior região nacional de efetivo leiteiro ovino. Para tal, é desenvolvida uma Análise do Ciclo de Vida (ACV) e correspondente tratamento dos dados na ferramenta computacional GaBi, permitindo analisar os impactos ambientais das alterações climáticas, acidificação terrestre e eutrofização das águas de todos os processos produtivos, não somente da queijaria, mas também de uma exploração leiteira típica da região onde se inclui a análise à fábrica fornecedora da ração animal. Neste sentido, analisam-se as entradas e saídas de cada sistema segundo uma fronteira de berço-à-portão, com o intuito de obter os impactos ambientais deste queijo tradicional regional. Na tentativa de tornar este produto mais ecológico, constituíram-se cenários alternativos recorrendo à utilização de energias renováveis na queijaria.
Tal como era expectável de outros estudos semelhantes, os resultados revelam que é na produção de leite da exploração leiteira onde ocorrem os maiores impactos das quatro categorias selecionadas, sobretudo devido ao cultivo da alimentação por forragens e também necessária na produção da ração animal, onde estão contidos os processos de fertilização e de preparação dos terrenos. Também a fermentação entérica dos animais, bem como a gestão dos estrumes apresentaram contribuições relevantes.
Esta análise detalhada permite concluir que no panorama global, o impacto da queijaria é praticamente insignificante. As soluções apresentadas nos cenários alternativos apresentam melhorias reduzidas. Ainda assim, este resultado pode ser colocado a favor da queijaria, redirecionando o marketing e a publicidade para uma vertente ambiental cuidada e pouco impactante dos processos produtivos da queijaria, e consequentemente dos produtos nela produzidos.
Nowadays, there is a growing promotion to label products ecologically in our markets. Knowing that every product will have an environmental impact associated with their production, it is of utmost importance to analyze all production processes for a better understanding of each process impact. The present study analyzes the environmental impacts of a regional product, the Beira Baixa cheese, coming from the largest portuguese sheep milk region. So, a Life Cycle Assessment (LCA) study was carried out, where the data was processed with the GaBi software, allowing an analysis of the environmental impacts contributing to climate change, terrestrial acidification and water eutrophication of all productive processes. Not only a cheesemaking industry was analyzed, but also the processes of a typical regional dairy farm including also the data of the supplying animal feed factory. In this sense, inputs and outputs of each system were analyzed within a cradle-to-gate boundary, in order to obtain the environmental impacts of this regional traditional cheese. In an attempt to make this product eco-friendlier, alternative scenarios were created using renewable energy sources within the dairy industry. As expected from similar studies, the results have shown that the greatest impacts occur within the milk production process for all four selected impact categories. This happens mainly due to the fodder cultivation process, also necessary for the production of animal feed, which contain processes of fertilization and land preparation. The enteric fermentation and manure management processes have also shown relevant contributions. With this detailed assessment it is shown that the cheesemaking industry has practically insignificant impacts. The alternative scenarios show small improvements. Nonetheless, the cheesemaking industry can promote their business with these results, by advertising and marketing their product as environmentally friendly with production processes causing reduced impacts and therefore also their products.
