Sausage and bacon grease get stored in seperate glass jars with lids and "recycled" in cooking - you just can't buy good drippin's at the store and beats having to render either one for making gravy to go over from rice, grits, biscuits, or toast.
I do this too, only I use a coffee can. The other, ickier grease I pour into a bigger coffee can with a lid that I keep under the sink. When it gets full, I freeze it the night before the garbage man comes and toss it in the trash the next day, wrapped in a couple of plastic bags.
