round here the council compost includes autumn road sweepings, so it’s full of plastic – harvesting my garlic there was a toffee crisp wrapper wrapped around the roots, metal ring pulls, plastic bottle top etc. these bits of litter kind of work their way to the surface over time so you can remove them but it’s quite disgusting. i think it is also cooked/sterilised in some way so it’s weirdly dead and wormless though it does fill up with life quickly once it’s spread.
it’s been ok for my own single raised bed but now we’re making a whole market garden. if we run out of the lovely hay and manure that we’re using to mulch i feel very torn about whether to get some council compost – the plastic bits would continually break down and leave nasty stuff in the soil, i’m sure, and cancel out our organic approach!
