A foam-flushing, composting toilet
I’m pretty sure we haven’t written about these before, but in any case MetaEfficient has the scoop on a “foam-flush” toilet by Clivus Multrum (I’ve never heard of them either). It uses a biodegradable soap/water mixture in very small quantities (3 oz) to flush, meaning it’s compatible with composting. Composting toilets are pretty gross, but if you think about toilets in general hard enough, they are all pretty gross. Not to mention toilets use an absurd amount of water (especially if you don’t let yellow mellow), so water savings like this has got to be a good thing. Shout-out to mhh5 on this one.
