We haven't had a green waste bin ever since it disappeared with the tenants. Luckily we are on 1200 square metres and we can compost most of our green waste. What we can't compost (meat etc.) goes in the bokashi bin.
My friend, Felicity, says bokashi has been miraculous at improving her garden. I hope so as it is it is a lot of work to lug it up to the back section and dig it in. Bokashi works using anaerobic fermentation with effective microorganisms (lactic acid bacteria, yeasts, photosynthetic bacteria, actinomycetes and fungi according to biome.com.au).. These come in the form of a bran which you sprinkle over your food waste. The airtight seal on the bucket keeps the fermentation anaerobic and there is another bucket below to catch the liquid (which can be diluted and used as a plant food.
You can put in things you cannot put in compost like meat, cheese, fish and cooked foods like bread rice and pasta. The only thing you can't put in is liquids. Even bones can go in there and I put in the poor little mice that we trap in the kitchen cupboard. Once the bin is full, you can leave it to ferment longer or bury it in the garden straight away. It is like blood and bone on steroids.
