Abstract(s)
Actualmente, as novas gerações dedicam uma maior atenção aos impactos nefastos de certos produtos na natureza. A seleção de produtos no momento da compra torna-se mais criteriosa, e se não pelo dever de cidadania, as empresas vêm-se forçadas a adaptar a sua realidade à procura dos consumidores, com produtos e processos mais amigos do ambiente. A sustentabilidade é o ponto de partida e de chegada de várias políticas e modelos desenvolvidos, para assegurar que o consumo de recursos de hoje, não comprometa a sua disponibilidade no futuro. Assim, diversos modelos foram desenvolvidos para impor e guiar os agentes económicos a prosseguir com uma filosofia que não assente apenas no consumo desmesurado, mas sim racional e responsável. No âmbito destes modelos, surge a necessidade de assegurar que os ciclos de vida dos produtos tenham um impacto reduzido. Para tal, o processo deve começar no desenvolvimento inicial do produto. O Eco-design, vem introduzir metodologias de avaliação de impacto do produto, desde a sua produção, tempo de vida e reciclagem. Neste trabalho, selecionou-se um produto existente há muitos anos no dia a dia das populações – garrafa de gás residencial em aço - e um produto substituto desenvolvido recentemente tendo em consideração as preocupações do ciclo de vida do produto, no ambiente – garrafa de gás residencial em compósito e aço. Para avaliar a efectiva evolução na passagem de um modelo tradicional, para um produto inovador e bem aceite pelo consumidor, implementou-se uma ferramenta de avaliação de Ecodesign – LiDS Wheel. Durante o processo de implementação da ferramenta na análise dos dois modelos, procurou-se analisar os critérios de análise das principais estratégias de Eco-design. Para tal, fez-se uma pesquisa sobre as características do produto final, mas também dos seus materiais e processos de produção. Os resultados obtidos permitem não só obter uma percepção das vantagens e desvantagens entre os 2 modelos, mas também perceber quais são as estratégias que ainda devem ser melhoradas em cada opção. Ou seja, a ferramenta serve igualmente de orientação para a melhoria dos actuais modelos, ou no desenvolvimento de produtos inovadores.
At present, the new generations are imposing more attention on the harmful impacts of certain products to the environment. The product selection in the purchasing moment, becomes more judicious, and if not for the duty of citizenship, companies are forced to adapt their reality to the consumers’ preferences, with products and processes more environmentally friendly. Sustainability is the point of departure and arrival of various policies and models developed to ensure that today's resource consumption does not compromise its availability in the future. Thus, several models have been developed to impose and guide economic agents to pursue a philosophy that is not based only on excessive consumption, but rational choices and responsibility. Within these models, there is a need to ensure that the product lifecycle has a reduced impact. To be more effective, the process must begin during the initial product development. Ecodesign introduces methodologies to evaluate the impact of the product, from its production, lifetime until the very end of product life. In this work, was chosen a product that exists for many years in the day-to-day life of the populations - residential steel gas cylinder - and a recently developed substitute product – residential composite and steel cylinder – where the product development has considered the lifecycle concerns, from the conception phase until the recycling stage. To evaluate the effective evolution in the passage from the traditional model, to an innovative product and well accepted by the consumer, an evaluation tool of Eco-design - LiDS Wheel was implemented. During the implementation process of the tool, to analyse the two models, was necessary to answer the criteria that define each of the main strategies of Eco-design. For this, research was done on the characteristics of the final product, but also on its materials and production processes. The results obtained, not only allows a perception of the advantages and disadvantages of the two models but also realize which are the strategies that still must be improved on each model. In other words, the tool also serves as a guide for the improvement of current models, or for the development of innovative products.
