For those of us too remote to have a direct mains sewerage connection, where a mains connection is impossible such as a narrow boat, houseboat or RV, or those that wish to take advantage of the nutrients we would otherwise flush away, a composting toilet may be the answer.
Composting toilets compost the waste into a form that can safely be used as fertiliser. They range in size from the dual box system that relies on natural decomposition and has the capacity to handle two years’ waste to smaller systems that use raking or tumbling mechanisms to speed up decomposition.
The better waterless toilet designs are silent, odour free and do not splash, and at the end of the decomposition process you will have free compost that can be used in the garden.
