The ability to tilt and rotate the zinc recycling plant is its main advantage. Prior to locking the furnace, lead scrap is placed inside with smelting flux.

Fewer quarries and mines, less noise, and lighter traffic all contribute to a lower environmental impact. conserves precious raw materials; metal ore reserves will last longer.
