I was given a load of that type of compost a few years ago, The odor did not dissipate over time so I took the 10yards of nasty compost and created three new heaps, adding my own materials to that stuff, after a month it was much nicer and then it went onto the gardens and around the fruittrees.
Most Municipal composting is made with a high heat process where they make very large windrows and don't turn it as often as it really needs to be turned in this method.
The high heat has to be done because of the "meat" products that are inevitable, they attempt to and are usually successful at killing at least most of the pathogens, but they don't take the time to truly finish the composting before they sell it or give it away.
I no longer bring in compost, I now have enough composting materials for my heaps (I usually have three going all the time).
There isn't really any thing wrong with municipal compost it just smells like it hasn't completed the break down and that is because it usually hasn't.
