Sounds to me that the stuff in the bin is only partly decomposed. The finished item looks like dark rich soil.

But I think it is ok to use in soil improvement so long as you don't mind it continuing to decompose in the soil. Some people do it this way all the time - it's jus that their plots look a bit untidy.

A friend of mine just used to tip kitchen peelings straight onto the found in his flower beds, until some peelings rooted and he ended up with a bumper crop of spuds - from peelings!
