People sometimes complain that all aluminium should be recycled back into ingots, but we only want the lightweight stuff the smelters don't value, stuff that often ends up in landfill or was- before they stopped it - exported to India and China. Also there is a huge and growing market for Aluminium Hydroxide for use- belatedly- as a fire retardant for plastic foam insulation, There is no home-grown bauxite in the UK, so all of our hydroxide (2 mullion tons a year) is mined, Bayer- processed and imported at a huge environmental cost.
Sure, but it would be nice to know exactly what was wrong that led to the mistake. I'd also like to know why it took so long to uncover and admit the error(s).
