COMPOSTING

Composting is a process that helps to reduce food waste and greenhouse gas emissions.

Compost is decayed organic matter. Organic matter comes from leaves to banana peels and a different range of other materials. When you mix a bunch of these items together in a compost pile, they break down naturally into a nutrient-rich fertilizer. It helps gardens grow, but can also have other applications.

What can be composted?

Almost anything that comes from the ground can be composted.

Avocado pits, apple cores, carrot peels, any vegetable or fruit scrap will do. But grains also sprout from soil, which means you can throw stale bread, cereal, and pasta in your compost heap, too. Coffee grounds and filters, tea leaves, herbs, spices, nuts and egg shells are all acceptable ingredients. Flowers or plants also can be composted.

The benefits of composting

When the food in your trash goes to a landfill, it emits methane,

a greenhouse gas that contributes to climate change.

Composting is a way to minimize those methane emissions.

In addition, the compost can be used as a fertilizer,

which reduces the need for chemical options.

On top of all the great things compost does for the environment, it is also a

valuable tool for farmers and gardeners. Compost boosts water retention in

soil, which means the budding plants in that soil need less irrigation.

This all adds up to more growth with less water and, in turn, a more

affordable way to create food, flowers, and other plants.
