Well here is my first tip. Gosh I know you've all been waiting with bated breath.
Ditch the bin liner! - it's just added plastic and not really necessary
We no longer put plastic garbage bag liners in our bin (both indoor & outdoor bins). It sounds messy, and now and then it is. All our food scraps end up in the compost heap, or in the chook yard. So really, the rubbish in our bin is mostly clean. If the bin gets a bit sticky, I give it a quick swoosh-out with water and washing-up detegent and leave it in the sun to dry. Too easy.
