I helped commission a lot of the electrics at RBF before it went into operation.I was on the shift that blew it in all those years ago. Working in the control room and recording charges, pressures, gas flows, temperatures, water flows and a million other things. Spent 16 years on it.
It's "greener" than digging new iron ore out of the ground and making that into steel. And then there will be other metals in there too I would expect, copper probably in cabling (unless that has already been stripped)burning all that up for scrap does not sound very 'green'.
