For sowing seeds I've always used multi-purpose, but have always sieved it before use. I've never been that bothered about whether it's peat free or not. This year I bought 3 bags of Westland with added JI. It wasn't as fluffy as the stuff I've used previously, and has quite a few bits of fibrous stuff in it that I wouldn't be happy to sow into - but as I said previously, I've always riddled potting compost prior to seed sowing anyway.
I've saved the riddled bits to use as a base for stuff that I'm potting on. I haven't found any bits of glass, wood or rubbish in it. If the companies are using council composted green waste as a major constitiuent, and that waste is contaminated with uncompostable waste, then who is responsible?
