Asbestos sheets found in garden

We have unearthed some old asbestos sheets in our garden, I have bagged the smaller loose broken stuff but there are other larger part sheets which I obviously do not want to break
Has anyone an idea where, in or anywhere close to area 23 there may be a place we can dispose of it. or will it have to be collected ? I hate the stuff, it scares me just having it on the property :fearful:

Ask at your local dechetterie as several times a year ours allows people to dispose of asbestos and tyres.
