Composting food lets you dispose of your organic material and use them later.If someone wanted to start a compost, they would have to buy a bin or close off a section to your yard and start with a bottom layer of carbon such as paper or hay, this layer will give the compost some air and ability to break down. Now throw any organic materials inside as well as some soil and your food will breakdown to create nutrients in the soil which can be useful for gardening and potentially save you money.
