Hiya Richy, I watched a programme today (How they do it (or something like that)) and they sprayed disinfectant on it then scraped it with scrapers and bagged it.
The guy that was doing the job said they had filled a small transit and a 7.5 tonne lorry with infected loft insulation and bird poop he said it was knee deep

.
As for is there any money in it. I don't know, sorry I can't help with that part of your question
