I'm looking for two bags.
1. large Biodegradable shopping bag
2. biodegradable dog dropping bags
Any suggestions from personal experience with links would be appreciated!!!
Hmm...I'm not sure about large biodegradable shopping bags but for dog clean-up bags, there's BioBag (http://greenhome.huddler.com/products/biobag-compostable-bags) - I'm pretty sure they have bags specifically sized for picking up after your dog. They also have bags for kitchen, trash and lawn scraps. I've only used the kitchen ones, which I assume are made of the same material as the rest of them. They're quite good. They stretch out a bit if you pack heavy stuff into them and if you leave food scraps, etc. in them for a while, they will leak as I think they are a bit more porous than normal plastic.
Biobag does indeed make a "dog waste"-size bag: http://www.biobagusa.com/biobag_dog.htm#dog.
They also make litter-box liners: http://www.biobagusa.com/biobag_dog.htm#cat.
Considering that the Pooch Pick-up brand only contains 5% biodegradable resin (the rest is plastic), I will be switching to Biobag.
