Most of your kitchen waste can be recycled directly into your compost bin. You may have concerns that fruit and its skins will make your compost too acidic and hinder its breakdown, but this is not accurate. As with all ingredients of your compost, simply make sure the fruit is in proportion with the other ingredients of your compost bin. Do not fill your compost with banana and banana peels. Rather, mix the banana and peels with other sources of carbon such as straw, shredded paper and dried leaves as well as sources of nitrogen such as coffee grounds, egg shells and vegetable waste.
Break up into smaller pieces any uneaten banana, as well as the banana peel.
Place and store your uneaten banana and banana peels in your compost pail, a tightly covered storage container or an outdoor container.
Mix your banana pieces into your compost pile, bin or vermicomposter, spreading the pieces out for faster composting.
