James Grobler: The current market volume is around 1,500 t/month, and we can see growth of around 15pc/yr continuing, so if the trend stays around this level, we could see growth of about 75pc over the next five years. This market is driven by the household sector, but we could see demand emerging from the commercial sector, with one company planning to start operations that could result in additional demand of about 1,000 t/month by 2019.
