GAH! why did they use eco friendly polystyrene?!

[Kaykay]

Just a little vent, and I thought you folks might understand! Just as a disclaimer, I'm normally the sort of person who would support eco friendly efforts but...

I took a load of polystyrene peanuts from a delivery we had at work to use for a number of my chids which needed repotting. As I've now discovered a week later, it was eco-friendly (maize based?) stuff- so has all decayed, blocked my drainage holes and is now causing me more than a bit of a headache. For one of my finer potted chids it's also mixed in the medium, so I've wasted a pot load of good stuff for nothing. Plus, the time involved in repotting once more, and I'm going to have to put the pots through the wash to get the white goo off them.
Seriously. I'm all up for looking after our planet, but a little consideration from the packers to advertise their biodegradable packaging would have really helped here!!
So, moral of the story? If in doubt assume a delivery company's eco credentials are better than they really are. But only if wanting to reuse to care for a green growing thing. How perverse is that???!!!
