Any system has a capacity max. A tank size, a marine
coastal limit, a container, something.
In the case of any of the systems it's critical to understand that capacity and how to manage it.
In the case of composting heads, as with any, you EMPTY them when they reach capacity!
In our case, with the C-Head, you can bag it and carry it ashore to a dumpster, easier in my mind than pumping out liquid waste, or you have a secondary
container into which you transfer material when the system is full. Our head
uses a 5 gallon container with an adapted lid to hold the dry material. A 5 gallon container is small and pretty easily stowed. YOu can have more than one if for some reason you will be cruising in an area where you will not be able to reach shore to throw it away, or be in waters where dumping it over is appropriate.
The Natures Head could be transferred into a secondary container if needed , but easiest if you were able to make it to shore would be to bag it and throw it away.
To think that a composting head would hold waste until such a time that it was FULLY composted before emptying it seems to indicate a lack of understanding how the system works.
Which brings me back to; User error.
