The Blue Diamond Nature Calls Compositing Toilet is the first truly portable composting toilet designed to be used in a variety of settings. An environmentally responsible product, the separation of liquids and solids within the toilet allows for a much greener disposal of waste matters. This separation prevents the need for water or chemicals, and combined with Coffee Chaff or Sawdust (supplied separately) it both dries out the solid waste and also masks the smell. This system is used primarily in domestic composting and in domestic chicken coups. Solids can be added to any compost heap whereas liquids can just go down the drain.
