    Abstract : Textilkonsumtionen i världen idag är hög, varje år köpts och slängs textilier långt mer än vad världens resurser tillåter. I ett försök att hitta ett hållbart sätt att återanvända textilierna har institutionen för kemiteknik vid Lunds universitet påbörjat ett forskningsprojekt för att undersöka möjligheterna till att återanvända textilfibrerna från grunden; genom att bryta ner textilierna till fiber ska det gå att återanvända samma textilfiber till nya textilier i en ny åter-vinningsprocess.
