You can buy an elaborate charcoal composter for your kitchen countertop, or you can use any wide-mouth container with a tight lid already in your kitchen. A good choice for a countertop composter is a wide-mouth jug or can similar to those in which ground coffee is sold.
Place the jug or can on the counter next to the kitchen sink. This makes it easy to toss in wet vegetable peelings and other kitchen waste.
Add egg shells, coffee grounds and fruit peels to the compost container.
Toss small amounts of leftover vegetables and fruits into the container when they are available.
Empty the compost can into an outdoor compost bin at the end of each day or when it is full.
Rinse the jug outdoors with a garden hose. Wash and dry the jug with hot, soapy water when you bring it back indoors before using it again. This will help to prevent odors from building up.
