Thanks for all your helpful responses. I guess one factor in how fast the cardboard breaks down is climate. Since it's pretty warm here in Athens, GA, it might break down faster than in colder climates.

Is it ok to use cardboard that comes from beer cartons, cereal boxes, etc? I'm just wondering about the dyes used on the boxes. I think the ink in newspapers is ok because it's soy based, but I don't know about the ink used in your basic food and beverage packaging boxes. Any ideas?
