    Författare :Ping Wang; Centrum för analys och syntes; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; indole; sustainable polyesters; high performance; recycling; biodegradation;

    Sammanfattning : Plastics are widely used in our daily lives and industry. Unfortunaltely, most plastics are produced from non-renewable fossil resources. The transition toward sustainable resources such as various biomass is critically important for the future of plastic industry and the whole society. LÄS MER

  7. 10. Migration from plastic food packaging during microwave heating

    Författare :Jonas Alin; Minna Hakkarainen; Sahar Al-Malaika; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; migration; food packaging; microwave; degradation; food simulant; antioxidant;

    Sammanfattning : Microwave heating of food has increased rapidly as a food processing technique. This increases the concern that chemicals could migrate from food packaging to food. The specific effect of microwave heating in contrast to conventional heating on overall and specific migration from common plastic food storage boxes was studied in this work. LÄS MER
