Abstract(s)
Todos nós produzimos diariamente resíduos. Uma postura de evitar produzir resíduos
deverá sempre ser o objetivo primordial para conseguir reduzir o nosso impacto no
planeta. Sempre que tal não é possível deve-se apostar na correta separação dos resíduos
para a sua posterior reciclagem, nas nossas casas, e no nosso local de trabalho. Não tendo
sido encontrado um estudo a respeito da temática da separação dos RU no local de
trabalho em meio industrial, pareceu então fazer sentido a aplicação de um projeto de
investigação-ação incidindo sobre esse tema.
Os objetivos do presente trabalho são: caracterizar o processo de separação e reciclagem
de resíduos urbanos no complexo de cracking da Refinaria de Sines; identificar os pontos
críticos de recolha na instalação fabril; conhecer a perceção dos trabalhadores perante as
questões ligadas à separação dos resíduos; elaborar e implementar propostas de melhoria
e avaliar o seu impacto.
Assim optou-se por uma metodologia que contempla várias vertentes: análise de
documentos fornecidos pela empresa, inquérito aos 44 trabalhadores da área em estudo e
campanha de caracterização física dos resíduos indiferenciados.
O inquérito permitiu verificar que os trabalhadores concordam em separar os diferentes
resíduos para a reciclagem, sendo que 78% afirmou fazer a separação dos diferentes
resíduos para reciclagem na sua própria casa, mas no local de trabalho, a percentagem de
respostas afirmativas diminui para 69%. Os trabalhadores reconheceram ainda o impacto
ambiental, social e económico que a separação e reciclagem dos resíduos tem no futuro
da empresa, bem como a valorização da empresa pelas questões ligadas ao ambiente, não
deixando no entanto de apontar algumas falhas no sistema.
Por seu lado, as campanhas de caracterização física permitiram apurar que nos dias
observados os contentores de resíduos indiferenciados continham 13% de plástico, 5% de
papel e 4% de vidro. Pelo observado de uma forma geral, o descarte de resíduos com
potencial para reciclagem no contentor de indiferenciados é prática comum.
Foram elaboradas e apresentas propostas de melhoria ao sistema de gestão de resíduos na
instalação fabril. Estas medidas estão a ser consideradas pela empresa com vista à sua
implementação futura.
We all produce waste daily. Avoiding producing waste should always be the primary objective in order to reduce our impact on the planet. Whenever this is not possible, must focus on the correct separation of waste for subsequent recycling, in our homes and in our workplace. As no study was found on the topic of separation of RU in the workplace in an industrial environment, it then seemed to make sense to implement an action research project focusing on this topic. The objectives of this work are: to characterize the process of separation and recycling of urban waste in the cracking complex of the Sines Refinery; identify critical collection points in the manufacturing facility; understand workers' perception of issues related to waste separation; develop and implement improvement proposals and evaluate their impact. Therefore, a methodology was chosen that includes several aspects: analysis of documents provided by the company, survey of 44 workers in the area under study and a campaign to physically characterize undifferentiated waste. The survey revealed that workers agree to separate the different waste for recycling, with 78% saying they separate the different waste for recycling in their own home, but in the workplace, the percentage of affirmative responses decreases to 69% . The workers also recognized the environmental, social and economic impact that the separation and recycling of waste has on the company's future, as well as the company's appreciation for issues linked to the environment, whilst not failing to point out some flaws in the system. In turn, the physical characterization campaigns made it possible to determine that on the days observed, the undifferentiated waste containers contained 13% plastic, 5% paper and 4% glass. As observed in general, the disposal of waste with potential for recycling in the unsorted waste container is a common practice. Proposals for improving the waste management system at the manufacturing facility were developed and presented. These measures are being considered by the company with a view to their future implementation.
