Resumo(s)
Esta investigação teve como objetivo compreender como as metodologias Lean Thinking podem ser adaptadas e aplicadas à gestão doméstica dos alimentos, com o objetivo de reduzir o desperdício alimentar nos lares das famílias portuguesas. O desperdício alimentar é considerado um problema global com impactos negativos nos aspetos económicos, sociais e ambientais. Torna-se, assim, necessário estudar e aplicar soluções para o reduzir. De facto, para uma melhor análise do comportamento do consumidor foi utilizado o método quantitativo, através da aplicação de um questionário estruturado online, abrangendo uma amostra de 257 indivíduos de várias regiões de Portugal. Posteriormente, os dados foram analisados com métodos descritivos e estatísticos, como o teste qui-quadrado, para validar hipóteses propostas. Os resultados mostraram que a perceção do impacto económico do desperdício alimentar, a verificação regular dos alimentos disponíveis em casa e as competências culinárias mais desenvolvidas estão associadas à adoção de práticas eficazes contra o desperdício. Por outro lado, fatores isolados como o planeamento das refeições e restrições financeiras não são determinantes absolutos na prevenção do desperdício. Destacou-se a importância da sensibilização para as questões económicas, do desenvolvimento de competências culinárias e da organização eficiente das compras. A metodologia Lean Thinking mostra ser uma ferramenta adaptável e importante para promover uma gestão alimentar mais sustentável, eficiente e económica nas famílias portuguesas.
This research aimed to understand how Lean Thinking methodologies can be adapted and applied to domestic food management in order to reduce food waste in Portuguese households. Food waste is considered a global problem with negative economic, social and environmental impacts. It is therefore necessary to study and implement solutions to reduce it. For a better analysis of consumer behavior, the quantitative method was used, through the application of a structured online questionnaire, covering a sample of 257 individuals from various regions of Portugal. The data was then analyzed using descriptive and statistical methods, such as the chi-square test, to validate the proposed hypotheses. The results showed that perception of the economic impact of food waste, regular checking of food available at home and more developed cooking skills are associated with the adoption of effective anti-waste practices. On the other hand, isolated factors such as meal planning and financial constraints are not absolute determinants in preventing waste. The importance of raising awareness of economic issues, developing culinary skills, and organizing purchases efficiently was highlighted. The Lean Thinking methodology proves to be an adaptable and essential tool for promoting more sustainable, efficient and economical food management in Portuguese families.
