Common uses: 3- and 5-gallon reusable water bottles, Tupperware, biodegradable and compostable plastics. This plastic category, as its name of  “other” implies, is any plastic other than the named #1– #6 plastic types. These containers can be several different types of plastic polymers. Biodegradable
and compostable plastics are also labeled #7. Most recycling centers do not take plastic #7.*
