After collection, recyclables go to two local materials recovery facilities (MRFs) to be sorted and prepared for market. Many of these will become the same product in what is known as closed-loop recycling. For example, glass, aluminum, and steel can be used to make new bottles or cans. Many fibers, such as those from cardboard, are used to make new boxes. And most common household items contain some recycled materials. For example, recycled plastics are turned into new bottles, but they can also be made into carpeting, park benches, and fibers for clothing. The Keep America Beautiful website provides more detail about the recycling process.
