Hmmm... corncobs would smolder quite efficiently so I don't necessarily think that's a good idea... farmers typically used to keep two pails of corncobs in the house-- one by the woodheater for 'fire starters' and another in the bathroom, for, well, other reasons...
As a farmer/rancher who provides his farm to the local club (Challenger 498) I really prefer dog barf if one chooses to use paper wadding, which probably accounts for 98% of all flights... (never seen anybody use vegetation first hand). I don't
oppose using 'toilet paper' sheet wadding (Estes wadding), in fact in my high school days when the whole place was plowed up and cotton fields, I typically used regular toilet paper since there was virtually NO fire risk landing on bare dirt). However, sheet wadding does come down in unsightly 'litter' lying about on the field, and is slow to decompose. Dog barf settles through the grass to the soil surface and is rapidly broken down with the next rain... sheet wadding tends to stay up off the ground and survive a few rains before it starts to disintegrate.
But, then again, I get some 'free wadding' roaming around the pastures picking it up after a launch, which you don't get with dog barf...

Neither one bothers me in the least-- it's actually a fertilizer since our soils (as are most in the US) are deficient of boron, an essential micronutrient.
Of course for those going green, the leaf lettuce surely is the lowest environmental impact and is readily decomposed or eaten (if the animal in question can get past the sulfur stink).

PS.... NEVER use fiberglass insulation like some folks were thoughtlessly doing a few years back... that stuff NEVER disintegrates... OL JR
