Sludge from wet scrubbers requires an extra drying step. BOF dust or sludge is not a listed hazardous waste. It can be recycled to the blast furnace or sinter plant after briquetting or pelletizing. BOF slags are often recycled through the sinter plant and blast furnace because of its high lime content. BOF slags are also used as rail road ballast.

The steel furnace is the second-tier of furnaces. Compared to the stone furnace, it smelts at double the speed and therefore is a more efficient use of the given fuel. Steel furnace is comparable to electric furnace in terms of smelt speed, however the latter can make use of modules (as well as electricity) to further enhance the furnace's capabilities.
