Atualmente, as questões relacionadas com o meio ambiente têm vindo a ganhar grande importância na nossa sociedade e por essa razão, as organizações procuram soluções/ferramentas para diminuir o impacte das suas atividades no meio ambiente. A presente dissertação compreendeu a avaliação de aspetos e impactes ambientais, para apoio à implementação de um sistema de gestão ambiental, com enfoque na determinação dos aspetos ambientais associados à atividade desenvolvida, na Monteiro, Ribas – Embalagens Flexíveis, que se dedica à impressão e laminagem de filmes e à confeção de sacos e formatos, destinados à indústria alimentar. Paralelamente, pretendeu-se também rever e melhorar a gestão de produtos químicos. Inicialmente, foi realizado um diagnóstico ambiental de forma a entender de que modo estavam a evoluir as principais componentes ambientais (resíduos, emissões gasosas, consumo de energia e consumo de água), e a caracterizar os comportamentos ambientais da unidade. Relativamente aos resíduos, ao consumo de energia e ao consumo de água, observou-se que a sua produção e consumo registaram um aumento no período em análise, resultante, em grande parte, do aumento da capacidade de produção, decorrente da aquisição/instalação de mais equipamentos acompanhados pela contratação de novos colaboradores. Nas emissões gasosas, foram analisadas cinco fontes de emissão (FF1, FF2, FF6, FF7 e FF8), tendo-se concluído, que nos anos em estudo a concentração medida de todos os parâmetros foi inferior ao respetivo valor limite de emissão e que o caudal mássico medido se encontrava de acordo com a legislação em vigor. Após a realização do diagnóstico ambiental, e devido ao facto da Monteiro, Ribas – Embalagens Flexíveis ainda não possuir certificação ambiental, iniciou-se a fase de planeamento de um sistema de gestão ambiental, de acordo com a Norma ISO 14001:2015. Desta forma, procedeu-se ao levantamento de aspetos e impactes ambientais das atividades da unidade em estudo. Posteriormente, foi efetuada uma avaliação dos aspetos ambientais identificados, de forma a verificar os significativos, isto é, os que têm um maior impacte no meio ambiente, através da aplicação da metodologia de avaliação de significância considerada adequada para o efeito. Com base na metodologia de avaliação de significância, foi elaborada uma matriz de identificação e avaliação dos aspetos e impactes ambientais, de forma a implementar um sistema de gestão ambiental. No levantamento de aspetos e impactes ambientais, verificou-se que as atividades que apresentam um maior número de impactes são: preparação de tintas, sala de lavagem de tinteiros, impressão (flexografia e rotogravura), complexagem (com e sem solvente), corte, corte mandris e saqueiras. A partir da matriz de identificação e avaliação de aspetos e impactes ambientais, os aspetos considerados significativos foram: consumo de matérias-primas base solvente, consumo de outros materiais, consumo de energia elétrica, consumo de água industrial, e os resíduos: pó de cartão de mandris, absorventes filtrantes contaminados, lamas aquosas com substâncias perigosas, lamas contendo outros solventes e tintas de impressão contendo substâncias perigosas. Foram identificadas algumas medidas/ações a serem consideradas no âmbito do planeamento e controlo operacional, com vista à redução do impacte ambiental e promoção da melhoria contínua dos processos da organização. Por último foi elaborada uma preparação/resposta a emergências ambientais, neste âmbito foi efetuado um levantamento dos possíveis cenários de emergência e um estudo com as medidas de prevenção consideradas adequadas.
Currently, issues related to the environment have been gaining great importance in our society, and for this reason, organizations look for solutions/tools to reduce the impact of their activities on the environment. This dissertation included the evaluation of environmental aspects and impacts, to support the implementation of an environmental management system, focusing on the determination of environmental aspects associated with the activity developed at Monteiro, Ribas - Flexible Packaging, which is dedicated to printing and laminating films and making bags and formats for the food industry. In parallel, it was also intended to review and improve the management. Of chemical products. Initially, an environmental diagnosis was carried out in order to understand how the main environmental components (waste, gas emissions, energy consumption and water consumption) were evolving, and to characterize the unit's environmental behavior. Regarding waste, energy consumption and water consumption, it was observed that their production and consumption increased during the period under analysis, largely as a result of increased production capacity, due to the acquisition/installation of more equipment accompanied by the hiring of new employees. In gas emissions, five emission sources were analyzed (FF1, FF2, FF6, FF7 and FF8), with the conclusion that in the years under study the measured concentration of all parameters was below the respective emission limit value and that the mass flow measured is in accordance with the legislation in force. After the environmental diagnosis, and due to the fact that Monteiro, Ribas - Flexible Packaging does not have environmental certification yet, we started the planning phase of an environmental management system, according to ISO 14001:2015. Thus, we proceeded to the survey of environmental aspects and impacts of the activities of the unit under study. Subsequently, an assessment of the identified environmental aspects was carried out in order to verify the significant ones, i.e., those with a greater impact on the environment, through the application of the significance assessment methodology considered appropriate for this purpose. Based on the significance assessment methodology, a matrix for identifying and assessing environmental aspects and impacts was prepared in order to implement an environmental management system In the survey of aspects and impacts, it was verified that the activities that present the highest number of impacts are: ink preparation, ink washing room, printing (flexography and rotogravure), complexing (with and without solvent), cutting, cutting mandrels and looters. From the matrix for identification and evaluation of environmental aspects and impacts, the aspects considered significant were: consumption of solvent-based raw materials, consumption of other materials, electricity consumption, industrial water consumption and waste: cardboard dust from chucks, contaminated filter absorbents, aqueous sludge containing hazardous substances, sludge containing other solvents and printing inks containing hazardous substances. Some measures/actions to be considered in the scope of operational planning and control were identified, aiming at reducing the environmental impact and promoting the continuous improvement of the organization's processes. Finally, a preparation/response to environmental emergencies was prepared. In this context, a survey of possible emergency scenarios and a study with the prevention measures considered appropriate was carried out.
