Abstract(s)
Num contexto industrial cada vez mais preocupado com a sustentabilidade, a
implementação da metodologia Lean torna-se fundamental para otimizar processos,
reduzir desperdícios e promover uma gestão eficiente dos recursos. Durante o estágio
realizado numa empresa do setor têxtil, foi possível constatar a urgência de aplicar
metodologias eficazes, como esta, para enfrentar os desafios operacionais e ambientais. A
análise detalhada da gestão de resíduos têxteis e lixo orgânico dentro de fábrica, revelou
uma série de desafios, incluindo a contaminação dos resíduos, a falta de práticas de
reciclagem e a desorganização nos processos de recolha e armazenamento. Com base nessa
compreensão, foi desenvolvido um plano estratégico para implementar a metodologia 5S,
com metas específicas e áreas prioritárias identificadas. A posteriori foi realizado um plano
de ação para o fluxo de informação e um plano de propostas de melhoria dos problemas
detetados em chão de fábrica. Durante a implementação, foram adotadas medidas concretas
para cada etapa do processo 5S, incluindo classificação, organização, limpeza, padronização
e autodisciplina. Foram desenvolvidos documentos e recursos visuais, como mapas de fluxo
e procedimentos operacionais padrão (POPs), para orientar os operadores na adoção e
manutenção das práticas 5S. Além disso, foram propostas ações de sensibilização para a
importância das boas práticas de limpeza e reciclagem, visando promover uma cultura de
sustentabilidade na empresa. Durante todo o processo, foram identificados e enfrentados
desafios específicos, como a contaminação dos resíduos e o comportamento inadequado dos
operadores. Foram ainda determinados novos circuitos para os resíduos têxteis como as
ourelas, através do conhecimento adquirido com o acompanhamento do operador
encarregue pela recolha das mesmas. Depois foram determinados novos circuitos
otimizados para as rotas do lixo orgânico e da recolha de resíduo de fio, ao adotar
ferramentas avançadas como o MATLAB e algoritmos eficientes como árvore vasta do custo
mínimo e o algoritmo de otimização do problema do caixeiro-viajante, onde a rota dos fios
é aproximadamente de 43,5 m e a do lixo orgânico cerca de aproximadamente 117,8m.
Assim é demonstrado um compromisso com a inovação e a procura por soluções eficazes
para os desafios enfrentados pela empresa.
Este estágio proporcionou uma valiosa oportunidade de aplicar conhecimentos teóricos na
prática, contribuindo para a eficiência operacional e para a promoção da sustentabilidade
ambiental na empresa.
In an industrial context that is increasingly concerned with sustainability, the implementation of the Lean methodology is essential to optimise processes, reduce waste and promote efficient resource management. During my internship at a company in the textile sector, I realised the urgency of applying effective methodologies, such as this one, to tackle operational and environmental challenges. A detailed analysis of the management of textile waste and organic waste within the factory revealed a number of challenges, including waste contamination, a lack of recycling practices and disorganisation in the collection and storage processes. Based on this understanding, a strategic plan was developed to implement the 5S methodology, with specific targets and priority areas identified. Subsequently, an action plan was drawn up for the flow of information and a plan to propose improvements to the problems detected on the shop floor. During implementation, concrete measures were adopted for each stage of the 5S process, including classification, organisation, cleaning, standardisation and self-discipline. Documents and visual resources were developed, such as flow maps and standard operating procedures (SOPs), to guide operators in adopting and maintaining 5S practices. In addition, actions were proposed to raise awareness of the importance of good cleaning and recycling practices, with the aim of promoting a culture of sustainability in the company. Throughout the process, specific challenges were identified and tackled, such as waste contamination and inappropriate behaviour on the part of operators. New circuits were also determined for textile waste such as selvedges, based on the knowledge gained from working with the operator in charge of collecting them. New optimised circuits were then determined for the organic waste and yarn waste collection routes, by adopting advanced tools such as MATLAB and efficient algorithms such as the minimum cost spanning tree and the travelling salesman problem optimisation algorithm, where the yarn route is approximately 43.5m and the organic waste route approximately 117.8m. This demonstrates a commitment to innovation and the search for effective solutions to the challenges faced by the company. This internship provided a valuable opportunity to apply theoretical knowledge in practice, contributing to operational efficiency and promoting environmental sustainability in the company.
