My only experience with it was when a guy stuffed a bunch of it in a 55 gallon drum- after he put a body in it. Seemed effective in keeping the odor inside.
After 3+ years, and just like that it's like it's still 2015 Turned the computer on and there's 42 "likes". It is good chit, this is how I use it now, much mobetter handling a 3' x 10' piece. I now use leftover "barn metal" screws to keep it on, also mobetter.
