| Recycling turns
materials that would otherwise become waste into valuable
resources. Materials such as glass, metal, plastics, and
paper are collected, separated and sent to facilities that
can process them into new materials or products. Step 1.
Collection and Processing: Collection of recyclables varies
from community to community. There are four primary
collection methods: curbside, drop-off centers, buy-back
centers, and deposit/refund programs.
After collection, recyclables are delivered to a
materials recovery facility (MRF). At the MRF, materials are
sorted into separate marketable commodities for
manufacturing. Recyclables are bought and sold just like any
other commodity, and prices for the materials change and
fluctuate with the market.
Step 2. Manufacturing: Once cleaned and separated, the
recyclables are ready to undergo the second part of the
recycling loop. More and more of today's products are being
manufactured with total or partial recycled content. Common
household items that contain recycled materials include
newspapers and paper towels; aluminum, plastic, and glass
soft drink containers; steel cans; and plastic laundry
detergent bottles. Recycled materials also are used in
innovative applications such as recovered glass in roadway
asphalt (glassphalt) or recovered plastic in carpeting, park
benches, and pedestrian bridges.
Step 3. Purchasing Recycled Products: Purchasing recycled
products completes the recycling loop. By "buying recycled,"
governments, as well as businesses and individual consumers,
each play an important role in making the recycling process
a success. As consumers demand environmental products,
manufacturers will continue to meet that demand by producing
high quality recycled products.
