Plastic bags are made of a material that can be reused and made into other plastic bags. Old plastic bags are loaded into the recycling machine. The recycling machine liquefies the old plastic bags. Liquefied plastic is cooled with recirculated water. The cooled plastic is hardened into pellets which are siphoned up and extruded into a liquid state. Cool air is blown into the liquid plastic, creating a tube. The flattened tube of plastic film is rolled up. This plastic film is turned into new bags. This quick pollution-free process can be repeated indefinitely.
