The method of preparing compost from kitchen wastes with the help of red worms is called vermicomposting.
Method to prepare manure by vermicomposting (Activity): Take a wooden box and place it where there is neither too hot nor too cold. Spread a net at the bottom or spread sand as an alternative. Also, spread some vegetable waste along with it. Dried animal dung could also be used as a spread over-sand. Sprinkle some water to make this layer wet. The pit is ready for composting. Now put some red worms on the pit. Cover them loosely with a gunny bag. To feed red worms vegetable waste, coffee, tea leaves can be used.
