§ Mr. Bossomasked the Minister of Works why the slag, which could be advantageously converted into foamslag building blocks, is being deposited on hillsides or into the sea at a waste-charge of between 3s. to 5s. a ton.
§ Mr. SandysSlag is being foamed up to the full capacity of existing plants. In addition it is being put to other valuable uses apart from building blocks. Nevertheless we have not the means of utilising the full output of this by-product. For the present, therefore, a considerable proportion must continue to be tipped.
