摘要：

Mineralization percentages of ground starch-based films are similar (68-72%), whatever the degradation medium and the norm used, with standard deviations 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 carbon balances.
