For a long time, bromine was an important product made from brine. But that market has fallen away, since the lions share used to be made into lead scavengers for leaded petrol. The bromine works at Amlwch on Anglesey closed in 2004: https://www.octelamlwch.co.uk/ https://www.octelamlwch.co.uk/ The other obvious product would be magnesium, but they didn't isolate magnesium chloride at the bromine plant. The Wylfa nuclear power station was nearby, and Rio Tinto had an aluminium smelter nearby to provide a base load. Since magnesium is oftentimes produced through electrolysis a magnesium plant would have made sense, but somehow they didn't build one, likely for economic reasons.
