COVID-19 & composting toilets

The conventional toilet turns out to be an unexpected suspect in spreading coronavirus.

That’s because each flush inevitably sprays a few droplets up from the bowl. Public health experts worry that some of those droplets can contain the virus. There’s even a name for it: “the toilet plume.” They suggest a simple solution: Get people to close the lid before flushing.

With a big caution that the topic has yet to be researched, the risk could be lower for composting toilets. That’s because foam-flush composting toilets use only a tiny amount of water, which is then blanketed by a foamy soap. Splashes above the bowl are highly unlikely.

It’s unclear at this whether any significant spread can be attributed to toilet plumes. And, as I wrote above, the impact on potential infection from the lack of a splash from composting toilets hasn’t, as far as I know, been researched. Then again, there are other advantages to composting toilets. They conserve water, negate the needs for chemicals treatment of waste water, and produce organic fertilizer.
