Rotary screen harvested vermicompost, composed of worm castings Vermicompost (or vermi-compost) is the product of the process using various species of, usually,, and other, to create a mixture of decomposing vegetable or food waste, bedding materials, and vermicast. Vermicast (also called worm castings, worm humus, worm manure, or worm feces) is the end-product of the breakdown of by earthworms. These castings have been shown to contain reduced levels of contaminants and a higher saturation of nutrients than the organic materials before vermicomposting.

African Nightcrawlers ( ) are another set of popular composters. Canadian nightcrawlers (US) or common earthworm (UK)) are not recommended, as they burrow deeper than most compost bins can accommodate. Blueworms ( ) may be used in the tropics.

These species commonly are found in organic-rich soils throughout and and live in rotting, compost, and piles. They may be an in some areas.

Some systems use a, which consists of bedding materials for the earthworms to live in and acts as a large bin; organic material is added to it. Although the windrow has no physical barriers to prevent worms from escaping, in theory they should not due to an abundance of organic matter for them to feed on. Often windrows are used on a concrete surface to prevent predators from gaining access to the worm population. The and compost windrow turners were developed by Fletcher Sims Jr. Of the Compost Corporation in Canyon, Texas.

Here the worms are fed an inch of 'worm chow' across the top of the bed, and an inch of castings are harvested from below by pulling a breaker bar across the large mesh screen which forms the base of the bed. Because red worms are surface dwellers constantly moving towards the new food source, the flow-through system eliminates the need to separate worms from the castings before packaging.
