Those cans smell pretty bad when the stuff start decomposing so bad in fact that I gagged severely and almost puked late last summer when I opened it to rinse it out.
I dont used them anymore I just throw anything that is biodegradeable, out my window into the back yard.
The vegetable stuff rots away to nothing and anything edible is eaten by racoons and cougars. No bears yet.
Anything that burns is made into tight rolled up logs that i burn in the wood stove.
The very minimal amount of garbage that I generate gets taken to the garbage can at the local gas station to be thrown out when I am filling my tank with over priced and over taxed gasoline
