Plus the plastic is four steps in the food chain away from the food so I don't think you should be to worried about. Also HDPE 2 is one of the best plastics for storage because it is inert and only leaches if it left in the sun for days on end. It is also a non porous surface. Also from my understanding HDPE 2 is food grade.

Then I did peat moss which is not very eco, but is super forgiving on draining excess water and as well as staying moist. Now I use coconut coir, which is probably not much more eco than peatmoss. I'm shifting to sifted compost that I make myself and will see if that will work. Good bedding (water holding and shedding excess) for me means I can neglect them and they are still happy.

I have been wanting to make a large outdoor worm bin a lot like what you have but am concerned that racoons and other critters here enjoy digging up things in my garden so much, I will need to make a cover.
