Gangue, as the tailing of coal, can be used for the making, power making, cement making, road paving and so on. Everything can be beneficial is it is put in one right place, including the waste, so that is the reason why we always say that no waste is existing in this world, only some of them are being used wrongly in one unreasonable section.
