Simple plastic bins are by far the most common type of vermicomposting bin. They were first commercially available in North America in 1990 from Canadian Original Vermicomposter Ltd. (now Original Vermicomposter, Ltd.) and many other companies followed, very quickly, with a great number of bins. Their use is fairly simple. Fill your bin at least three-quarters full of damp bedding, add compost worms, then begin burying your organic waste. The occasional addition of bedding material is also helpful. When a significant portion of the material in the bin has been converted into vermicompost (usually 3-6 months), then its time to harvest.
As many first-time vermicomposters know, even a simple plastic tub with well-placed aeration holes can work just fine as a worm bin. Additional modifications, however, make it easier to keep your bin from having some of the problems typical of this type of bin. Most commercially-available worm bins incorporate multiple ventilation holes on the sides and top of the bin, a catchment basin or tray for excess liquid or a drain spigot.
