What to do with the (ahem) "material"? There are several options, depending on your situation - all vastly superior to storing stinky, hazardous, raw sewage in a holding tank and frequently looking for pumpout stations.

1. Remove the top of the toilet, then place a compostable plastic bag over the toilet base. Invert the base, dumping the contents into the plastic bag (this all takes about 2 minutes). Put the compostable plastic bag into another container - possibly a plastic pail with vent holes, or a composting bin. If new material was recently added you can cover everything with a layer of sawdust or other organic matter. Let it sit until fully composted - this will vary with temperature but is often about 12 weeks. Don't worry, it won't stink. It is then safe to put on flower beds (just to be 100% safe, don't put it on veggies).
   
   The contents of the solid waste tank may be safely placed into a conventional dumpster if it has been allowed to compost fully and is bagged and sealed. Or...
   

2. Boaters may dispose of the the material legally, offshore - as you would with a regular marine head with overboard flushing. Laws vary widely. Obey the law and use common sense where laws are not strict.
   
   
3. Urine is sterile and does not pose a health risk. Empty the urine bottle wherever you would legally take a pee.

Let's face it - holding tanks usually stink! Ask anyone who has slept in a bunk over a holding tank.

Entirely self-contained. No plumbing, no thru hulls, no holding tanks, no stinky sewage hoses.

Fits almost anywhere a standard marine head or porta-potti would fit (measure tight installations before ordering please).

Easy, do-it-yourself installation - or it can quickly be installed by a professional at minimal cost.

Gain a huge storage space when you remove your old holding tank!

Urine separating, even when trap door is open

Males may either sit or stand

After use agitator-crank is turned two or three times.

The urine bottle holds 2.2 gallons.

To empty, simply flip the two latches on the sides and lift the upper section up a few inches.

Put the lid on the liquid bottle and lift it out of its holder.

The solids bin will accommodate 60-80 uses depending on the composting time.

Approximately 2 gallons of peat moss (or coconut fiber) is used, to fill to 2” below the agitator.

Peat moss is moistened with water before adding.

Peat moss can be purchased inexpensively in small, compacted "bricks" for easy stowage.

A regular kitchen trash bag fits the base.

Just invert. After dumping, add new peat moss.

No need to clean as anything left helps to start the composting process more quickly.
