Flushing the toilet. That’s definitely an everyday thing.
What can help make it Everyday Sustainable?
There are low flush toilets, no flush toilets, and of course the old-fashioned torrential flush toilets. I’ve lived in households where the rule is to flush only when needed–in an effort to save water–, and where we flush every time–in order to be considerate to those with more sensitive noses. Right now, I live in the latter kind of household; flush every time. It drives me a bit nuts, but it’s a price I pay for domestic bliss.
In Japan, toilets often have “big” and “small” flush settings; you just flip the handle one way or the other. I’m housesitting now at a house that has toilets with an updated and lovelier–shall we say “lunar”–big and small flush design (from the Japanese master of toilets, Toto.)
This is a case where product design supports behavior around Everyday Sustainable.
