My outdoor cat litter has exploded

[EvianBaby]

In an attempt to get the cat to do his business outside I bought two long planter saucers and filled them with wood pellet litter. turns out that was a bad idea.

I've just looked in the garden and the stuff appears to have exploded. It's at least quadrupled in depth the top layer has broken down into a fine powdery substance but there is tons of it! What's the best way I can dispose of it? If I try and sprinkle it round the garden (I have no grass) will it eventually just vanish into thin air?
