Put it in a glass jar and bury it....that's what I do...of course I
always keep at least a 1/4 lb. in my possession. But that's what I found the easiest....you don't even have to bury it all the way....just dig a little hole in your backyard, throw some dirt on it, then a patch of grass.
If I don't have it there, I have a trash can I always keep half full....drop the green at the bottom, then set the bag on top of it. BOOM-SHAKALAKA, last place anyone would think to look....at least any normal person.
Ahh, the wonders of reverse psychology.
