Question

what code is not recycled​

Answer 1

Answer:

Recycling codes are used to identify the material from which an item is made, to facilitate easier recycling or other reprocessing. The presence on an item of a recycling code, a chasing arrows logo, or a resin code, is not an automatic indicator that a material is recyclable; it is an explanation of what the item is made of. Codes have been developed for batteries, biomatter/organic material, glass, metals, paper, and plastics.[citation needed] Various countries have adopted different codes. For example, the table below shows the polymer resin (plastic) codes. In the United States there are fewer, because ABS is placed with "others" in group 7.

They are made of any combination of 1-6 or another, less commonly used plastic. Biodegradable plastics, like cups made of corn, are NOT recyclable. Though they have the recycling #7, this only means "other plastics", including non-petroleum based.
