Food waste is a significant problem, with a family of four in the US throwing out $1600 worth of produce each year.
Composting food scraps significantly reduces methane production, a powerful greenhouse gas.
The composting process requires a balance of nitrogen (green) and carbon (brown) materials.
Finished compost is dark brown, smells earthy, and provides important nutrients for soil.
Composting can be done at home using simple household items, and the finished compost can be used for gardening.
