Composting has been described as sort of nature's way of recycling. To recycle is to collect material that can be used again later. In this sense, food scraps and other wastes are being collected so that they could be used again later in some form. Organic wastes and basically any living thing decompose, and when this happens, they become a substance that is high in nutrients. This can be mixed into soil, improving the structure of the soil, thereby allowing plants to grow better. As a result, we're turning something we don't need anymore into something that will benefit the environment.
Composting is nature's process of recycling decomposed organic materials into a rich soil known as compost. Leaves, grass clippings, and other garden refuse can be processed in a small area of a garden to produce decomposed organic matter that can be used as an excellent soil amendment and add some nutrients to the soil. Anything that was once living will decompose. Basically, backyard composting is an acceleration of the same process nature uses. By composting your organic waste you are returning nutrients back into the soil in order for the cycle of life to continue. Hence, it is recycling at its finest because instead of throwing out yard waste, it is converted to something useful to grow more plants.
