In late 2019, Australian magazine 'Slow Journal' decided to test how quickly compostable courier bags degraded in a home compost. The results speak for themselves. After just 6 weeks, just a few scraps of the Better Packaging Co. 'Real Dirt Bag' remained and after 9 weeks they could find no trace of it. The other satchel ... still almost 100% intact. Pretty obvious which ones the worms prefer!
