Worm Composting

Vermi-composting, or worm-based composting, uses red worms (Eisenia fetida) to digest the waste materials, leaving behind their nutrient-rich castings as the compost we collect.  Worms must be kept alive and healthy by maintaining worm boxes under high moisture content and at optimal temperatures between 55° F to 77° F. Worms create a very efficient composting system, where one pound of worms can process up to seven pounds of food waste per week, working continuously as the bin is filled. The worms are started in a damp “bedding” that usually consists of moistened newspaper or something similar, to which food waste can be regularly added.  Worm bins can be designed to have the appropriate size and worm density to compost all of the necessary food waste in just a few weeks. Since worms propagate in the bins, the system can be easily expanded by adding more bins and transferring worms. Elevation and/or sturdy wooden construction of the bins keeps pests away, and wooden construction gives lots of control in the aesthetic look of the bins, even turning them into functional benches when closed.
