im sure there would be a collection agency.

when i was working on my mates garage converting it we had to get rid of asbestos and what i done was phone the local council and they gave me numbers of collectors and they wasnt cheap.

for a few slabs, teh cheapest i found was £700, £700 for 20 minutes work cus then had to be careful and came dressed in them space suits.

but yeah, there should be a number your local council can give you or in your yellow pages for an agency.

chemical disposal or summet id think it would come under :S

i wouldnt recommend handling them yourself cus if you drop one i dont know what youll be inhaling.
