Eliminate Food Waste
"You can put everything in—meat, fish, eggs, the works," Sophie says. "You just throw it all in there. Put a few handfuls of sawdust pellets, a bit of baking soda. It grinds it up, and it heats it. With this, you get the compost very, very quickly."
If you don't have an outdoor space like Julia's, Sophie suggests taking your compost to a friend with a yard or scattering it on a roadside.
