We're trying our best to eliminate plastic bags from our household diet. We are using canvas bags for groceries, and have even been taking bags to department stores to reuse. Our old plastic bags have been serving as small trash can bags and doggie poop bags.
We walk our basset hound 1-2 times a day, and we realized that our use of plastic bags, even for things like poo, were still going to take a really long time to degrade in the landfill. So we decided to give these bags a try.
I like the fact that they are made from cornstarch and will degrade naturally like food scraps. We keep a poopie composting bin, which we empty into the trash every so often (don't put this in your regular compost, since dogs eat meat and their waste can contain E. coli). It will be nice to have our bags degrade along with the waste.
My main complaint is that the bags should be larger. It takes quite a bit of concentration to make sure using these bags doesn't turn into a disgusting mess! Our basset is a runt, but she is still 60 pounds. This size bag might work well for a really small dog, but not for larger dogs. Also, I have started to bring 2 bags along to contain the smell a little better (I used to use 2 plastic bags for the same purpose).
I have looked online, and see that larger bags are available. I think that I will purchase larger bags next time, and try to get a discount for ordering a larger volume (this can also be found online). Overall, I would recommend giving them a try if you're looking for a more environmentally-friendly alternative to plastic bags!
