Re composting.
One often sees old pieces of carpet thrown onto waste land. Very often it has started to decompose or is well into being composted. I can see that the nylon types of fabrics would not decompose but what about all wool carpeting? Would this be suitable to be put into a compost heap - between layers of the usual garden and kitchen waste?



Sounds a bit odd. I may be wrong but I think carpet is used to keep the compost warm and dark, not as compost material.

Yes, Cammomile is right, carpet is usually used to keep the heat in. I have done this on my large compost bins on the allotment and after a year or two they do start to degrade. Eventually they will get incorporated into the heap, but as I say they are large bins. You are right about the woollen carpets, nylon will never work.

Any organic material will eventually rot away. So yes you can put wool in a compost heap along with feathers, leather, linen, cotton and so on. It just might take a rather long time to break down that's all. Like years rather than months.

I think it would be unusual to have 100% wool carpet as usually the mix is 70% wool.

If you wanted to put a wool carpet in the compost, though, I would chop it up well, and make sure that it is less than 5% of the mix. As Owdboggy says, you're likely to be screening out those bits of carpet for years to come, though it will slowly add nitrogen to the mix.
