The Separett Burn is a wood incinerator for the solid waste from urine separating toilets. The principle is that the bag from a urine-separating toilet, eg. a Separett Villa, Biolan Simplett, or Separett Tiny, is placed on the rack inside the incinerator. Wood is placed in the fire box below the rack to start the fire, and the solid waste and the bag burn up, leaving only ashes. The amount of wood that is used is determined by the amount of solid waste. The Separett Burn is used outside. It works in all temperatures.
