This is one of the major problems with the recycling process, the cost of metals? But there remains a high demand for old metal and spare parts for all those classic cars out there, with much encouragement to rebuild old motors?
Today in the age of the throw away there is now a demand for retro-era machines, because they do last longer and do the same job as efficiently without the tech!
in some aspects this has worked for ships, aircraft and locomotives, but their problem is the coating of asbestos and that is why so many diesel trains are in the slow progress of being scrapped?
