I'm ashamed to post these photos of stuff out of my compost heap. I am always very careful to ensure anything I put on the heap is compostable, but every year it's the same, plastic stuff finds its way in. I guess some of it may be from so-called compostable bags which I have discovered do not compost in my heap which never gets up to temperature. But what are these little strips of plastic from? Some of them seem to have remains of a bar code on them. Should I suspect one of my family surreptitiously using the heap as a rubbish bin .... ?
