The message
from "Aileen Howard" contains these words:

If I insisted, I'm sure I could have a compost bin, but I just respect his
feelings about them.

Why not install a neat discreet compost container without drawing his
attention to it? As he's not a gardener, he probably won't even notice
it, or realise what it is.

I've known married men who swear they would never touch food containing
that stinky furrin garlic/herb/spice rubbish, sleep under a bag of bird
feathers, use a deodorant soap etc. Some of them are unaware that they
have been happily eating/sleeping/ washing with the enemy for decades.
