Worm composting: using worms to recycle food scraps and other organic material into a valuable soil amendment called vermicompost, or worm compost.
Worms eat food scraps, which become compost as they pass through the worm's body. Compost exits the worm through its' tail end. This compost can then be used to grow plants. To understand why vermicompost is good for plants, remember that the worms are eating nutrient-rich fruit and vegetable scraps, and turning them into nutrient-rich compost.
Bokashi Bin Set
Bokashi composting: a method of quickly breaking down organic waste via fermentation.
Unlike conventional composting, a Bokashi system, which is anaerobic, makes use of Effective Microorganisms (EM) that are added to the organic waste stored in a Bokashi bin.
Hugelkultur composting: a method that uses large pieces of rotting wood as the centerpiece for long term humus building decomposition.
The decomposition process takes place below the ground, while at the same time allowing you to cultivate the raised, or sunken, hugelkultur bed. This allows the plants to take advantage of nutrients released during decomposition.
