What is a macerator?

A macerator is a device used to breakdown waste from the toilet into a slurry form so that it can be pumped against gravity into a holding tank or other sewage system.

not widely used in UK

One of the main uses of the Macerator early game is doubling mining profit. Every ore block placed into the Macerator creates two ore dust. If macerating Redstone Ore, it outputs 6 redstone dust, instead of the usual 4-5. Each piece of dust can be smelted into a single ingot, yielding two ingots for each ore, if macerated.
