    Brief use instructions

    Compost Green
    Add 1 scoop of Compost Green before the urinal chamber is used. The best method is to pour the powder into the urinal and then rinse down with a little water or Nature Flush.
    Coco Peat Bricks
    Wet the Coco Peat brick with 5 litres of water and allow it to swell for 1 hour before use. Add a handful to the #2 solids chamber after every use.
    For convenience, Sun-Mar™ | GTG WET Mix is also available pre-made.

    Compost Green additive

    The Compost Green additive is effective at improving the condition of urine tanked in bottles or larger holding tanks.

    Application use

    • Odour from the system caused by the wrong media or bulking agent being added.

    Compost Green features

    • Powerful ammonia treatment.
    • Microbiological habitat, adding an ideal surface area for bacteria and fungi.
    • Drying by volume effect.
    • Chemical heavy metals binding.

    Coco Peat bricks

    Coco Peat is made from 100% natural fibre of the coconut husk. It is a waste product from the production of coconut products and is now readily used in many industries as a reliable and sustainable organic fibre.

    One of the main uses is as a growing media and it is increasingly used as a natural replacement for peat. While peat resources are depleting and harvesting is considered environmentally damaging, Coco Peat is a fully renewable resource as more coconuts are grown.

    WCTNZ® has chosen and recommends the use of Coco Peat for its many environmental benefits.

    For use in urine-diverting composting toilets as a wet cover material in the #2 solids chamber after use.
