Abstract(s)
Devido à expansão tecnológica, o aumento dos resíduos de equipamentos elétricos e eletrónicos (REEEs) mostra-se uma preocupação global. A complexidade destes resíduos dificulta o processo de reciclagem encontram-se abrangidos por uma vasta lista de exigências legais. Os plásticos são uma fração considerável destes resíduos e as respetivas funcionalidades exigem diferentes tipologias de polímeros e a adição de poluentes orgânicos persistentes (POPs), cuja remoção e eliminação é obrigatória. Este estágio teve como objetivo apoiar as atividades de gestão ambiental numa empresa de reciclagem de REEEs, em particular no processo de desclassificação dos plásticos dos REEEs através da aplicação do Fim de Estatuto de Resíduo (FER) e atualização do enquadramento e obrigações legais. A empresa detém uma licença ambiental atualizada comprovando o cumprimento das suas obrigações legais, aguardando-se a atualização para o regime de Licenciamento Único Ambiental. O atual método de reciclagem de plásticos utilizado pela empresa, bem com a incerteza relativamente à concentração de POPs presentes nas misturas de polímeros, impede, para já, a aplicação do FER. Em conclusão, é crucial equacionar a problemática dos REEEs desde o momento da conceção dos equipamentos, por forma a otimizar os processos de reciclagem.
The increase of electrical and electronic equipment waste (WEEE) has become a global concern due to the technological development. The complexity associated with these wastes makes the recycling process difficult which also needs to comply with a vast list of legal requirements. Plastics are a considerable fraction of these residues and their functionalities demanded the addition of persistent organic pollutants (POPs), whose removal and disposal is mandatory. This internship aimed to support environmental management activities in a WEEE recycling company, by declassifying plastic wastes and updating the company's legal framework and obligations. The company has an updated environmental license demonstrating is compliance with the legal obligations which is waiting to be upgraded to the Unique Environmental Licensing regime. Moreover, the current method of plastics recycling and the uncertainty regarding POPs concentrations prevented the plastics declassification as wastes. In summary, to properly tackle the WEEE challenges electrical and electronic equipment should be designed having into consideration their full life cycle.
