Compost works by micro organisms breaking down your waste in the presence of air. It's less fussy than wormfarms and gets through more scraps. But it needs an outdoor space and garden waste to mix in with your food scraps.
Composting suits if you
- want to compost garden materials as well as your food scraps.
- have space on bare earth to put the compost bin.
- are in a household with more than two people.
The benefits are
- you can add a greater variety of food and other materials than in a wormfarm including garlic, onion, citrus, and garden waste.
- it will tolerate heat and rain.
- you can add larger volumes of materials and it operates at full capacity as soon as you set it up.
Worm farms work well for apartments and children love them. Worm farms need a very sheltered location and cannot process as much material as a compost bin. The variety of material you can put in a worm farm is also more limited than with a compost bin.
Wormfarming suits if you
- don't have any garden materials to get rid of.
- don't have access to any bare earth.
- have a small household or you don’t produce a lot of food scraps.
The benefits are
- the liquid fertiliser from your wormfarm is easy to harvest and apply to your garden.
- you can keep your wormfarm in a courtyard, on a balcony or even inside.
- you don’t need to add garden materials.
Bokashi uses anaerobic bacteria to ferment food waste, including meat, dairy, bread, and small bones, into a readily decomposable form in a sealed bin, minimising insects and odour.
Bokashi suits if you:
- have somewhere to bury the fermented semi-solid matter (patch or large pot of soil, compost bin, or community garden)
- would also like to compost meat, dairy, bread, and small bones
The benefits are:
- it's compact and sealed, so can be used indoors or outdoors
- it can handle meat, dairy, bread, small bones, citrus, onion, and most other food scraps
- it produces nitrogen-rich liquid and semi-solid fertiliser that, when diluted, are great for a garden and pot plants
