They were saying, not too long ago, McGrath, here in the US at least, that paper bags take up a lot more room in the landfills than plastic. I tend to save paper bags and use them for other things, plastic as well, actually. But it got to be a bit confusing for people to try to figure out which kind of bag was worse for the enviornment. If the corn bags are bio-degradable, I might consider putting them in my compost pile or using them for mulch.
