dc.description.abstract | The invention aims at recycling low-density polyethylene (LDPE). It refers to a LDPE film destruction procedure consisting of 3 consecutive stages: (a) LDPE photooxidation by UV radiation, (b) LDPE treatment by a nanocomposite containing magnesium ferrite stabilized by polyvinylpyrrolidone, and (c) LDPE incubation in a mineral medium amended with hydrolyzed lignin waste. The procedure permits acceleration of the processes of LDPE biodegradation up to the level of 18% of weight loss in at most 100 incubation days. | en_US |
dc.description.abstract | Invenția se referă la reciclarea polietilenei de densitate joasă (LDPE), în particular la un procedeu de distrugere a peliculelor de LDPE în 3 etape: (a) fotooxidarea LDPE prin iradierea cu UV, (b) tratarea LDPE cu nanocompozitul de ferită de magneziu stabilizată cu polivinilpirolidonă și (c) incubarea peliculei în mediul mineral cu adaos de lignină hidrolizată. Rezultatul invenției constă în accelerarea biodegradării deșeurilor de polietilenă – până la gradul de distrugere de 18% după 100 zile incubaționale. | en_US |
