Composting moss

My husband is insisting that he will compost a whole cubic meter of moss after scarifying the lawn. I have never tried composting moss as I didn't think it was possible. Does any one have any advice or help that I can give him as it doesn't seem to be working very well.

It doesn't compost down, you'll just be spreading moss when you use the compost.

I don't know, never managed to do a hot one 

I experimented last year when my mate was doing a lot of scarifying in his gardening business. It was all pretreated with Iron Sulphate first to kill it and then I put in in a big heap and covered it. My first mistake was  covering it before it gone thoroughly wet as a lot just sat there and made an ideal home for mice😡. The cover was taken off in autumn and it seems to be breaking down ok now. I did use a fair bit a couple of months ago as a mulch for a large bed to suppress weeds over winter and will plant through it in the spring.
