Claims (3)
- REIVINDICAÇÕES 1. Processo de reciclagem de resíduos de folha complexa compreendendo, pelo menos, uma folha polimérica destinada a formar recipientes, a qual recebeu à sua superfície uma película de selagem soldada, caracterizado por compreender as seguintes etapas: a. moagem dos resíduos, b. separação mecânica dos resíduos moídos com o objectivo de separar as partículas leves das partículas pesadas compreendendo maioritariamente a folha polimérica, c. separação mecânica por peneiro das partículas leves provenientes da etapa b) a fim de separar as partículas de dimensões muito pequenas provenientes apenas da película de selagem e as partículas de polímero de dimensões maiores que constituem o rejeitado do peneiro, d. reagrupamento das partículas de polímero que correspondem às partículas pesadas da etapa b) e as partículas que constituem o rejeitado do peneiro da etapa c), e. fusão das partículas de polímero da etapa d) e filtração do polímero fundido.
- 2. Processo de reciclagem de resíduos de acordo com a reivindicação 1, caracterizado por a separação mecânica da etapa b) ser realizada por ciclonagem com contracorrente de ar.
- 3 . Processo de reciclagem de resíduos de acordo com qualquer uma das reivindicações anteriores, caracterizado por a etapa de moagem produzir partículas de dimensões compreendidas entre 1 e 5 milímetros.
