Food waste is ravaging our beautiful ecosystem. These days, it’s becoming more and more evident that diverting food waste from landfills is of EXTREME importance for the survival of our planet. But what about the people who don’t have access to an outdoor compost system? This article will explore the top 5 methods for composting in a small space.
Vermicomposting is a fancy way of saying that you use worms to break down your waste for you. A vermicompost is a long, shallow bin made from wood or plastic. The interior is composed of shredded “brown” compost material (such as cardboard, paper or peat moss). The ideal size and number of worms will depend on how much food your household generates. Generally speaking, for every pound of food waste you generate, you will need one square foot of space, and two pounds of worms. FYI: For an easy size-to-waste ratio, keep Mary Appelhof’s 1-2-3 Worm Binmeasurement in mind (1 ‘ deep, 2 ‘ wide, 3 ‘ long). Will vermicomposting work for you?
Bokashi composting is a low-cost, natural process which reduces and transforms food waste by fermenting organic material into a nutrient-dense end-product. Because bokashi requires an anaerobic (no air) environment to succeed, it is more like pickling your food scraps rather than composting them (as composting requires an aerobic environment).
3. Compost Tumblers
When comparing compost tumblers to your garden-variety (pun-intended) compost bin, think of the compost tumbler like a Compost Pile 2.0: the tumbler speeds up the composting process by allowing you to turn the bin manually, therefore completely aerating your food waste. Often larger than vermicomposting bins, compost tumblers may only be an option for those with access to a communal garden space or a fairly roomy balcony.
