Titan say they will remove the asbestos before they start. Asbestos! Surely asbestos has not been usegd for insulation for a generation?
As for the value of the scrap metal, tankers and ore carriers go for $4-500 per light ton. A light ton is the weight of the metal in a ship, less than displacement, or gross, but perhaps similar to nett. However, there will be a lot of unusable rubbish in a liner, such as plastics and wood, so it will probably be worth less.
