I prepare a small cardbox as staging area for my kitchen waste, so that I don't need to store axcess kitchen waste in the fridge.
It is actually Japanese Cardboard Compost using Cocopeat and Rice Husk Ash (add water to keep moist). I am worried the worm might not like ash, so I only add in a minimal amount of ash in this staging compost box.
I am not sure whether this idea of staging compost box for the worm bin will actually work.
The bottom is reinforced with extra layer of cardboard, and the bottom gap is sealed with tape to avoid insect getting in. Cardbox is breathable, so there is no need to drill hole. Cover the top with an old t-shirt.
