Abstract
Mineralization percentages of ground starch-based films are similar (68-72% ), whatever the degradation medium and the norm used, with standard deviati ons less than 8%. Vermiculite, an inert solid medium, shows an intermediary behaviour, between liquid and compost media. Consequently, this support is suitable for further degradation studies, including the determination of c arbon balances.
