Raw toilet waste contains bacteria that should not be let without treatment to the nature, especially not to any water body. During composting, this bacteria will die and the compost turns into valuable fertilizer to be used in the garden. According the regulations, the composting should be done so that not any liquid leaks out. Green Toilet Waste Composter meets the standards and is an easy way to handle toilet waste safely.


The most important part of the Green Toilet Waste Composter is the double capillary base, which works like an under watering flower pot. It lets excess liquid out of the compost mass, but also enables some of the liquid to be absorbed backwards. Thus, the compost will stay adequately moist and composting is efficient.

The excess liquid is led through the hose to a canister. This seap liquid can usually be poured back to the compost, where the urine will speed up the process.

There is a ventilation hat on the top and ventilation holes on the sides, which will let necessary oxygen in.

In these toilets the waste does not compost at all or not enough. In Green Composter the treatment of the waste is easy.


It is recommended to compost toilet waste 6-12 months depending on the climate. It is not allowed to let the excess liquid to leak out. In Green Composter the liquid is collected and it can be composted together with the solid waste. If the waste is very wet, some dry material, such as peat should be added.

The compost is ready when it looks like mulch and there is no odor. Then it can be safely used in the garden.

If there is a lot of toilet waste to handle, it might be a good idea to have two composters: when one is used and material added into it, the other one can be let to decompose gradually.

What if the composter freezes?

That is not a problem. Green toilet waste composter can freeze, even if it is full, without any damage to the structure.
