Recycling codes

From Wikipedia, the free encyclopedia
Jump to: navigation, search

Recycling codes are used to identify the material from which an item is made, to facilitate easier recycling or other reprocessing. Having a recycling code, the chasing arrows logo or a resin code on an item is not an automatic indicator that a material is recyclable but rather an explanation of what the item is. Such symbols have been defined 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 codes (plastic) for a country. In the United States, there are fewer as ABS is grouped in with other in group 7. Other countries have a more granular recycling code system. For example, China's polymer identification system has seven different classifications of plastic, five different symbols for post-consumer paths, and 140 identification codes.[1] The lack of codes in some countries has encouraged those who can fabricate their own plastic products, such as RepRap and other prosumer 3-D printer users, to adopt a voluntary recycling code based on the more comprehensive Chinese system.[2]

  1. ^ a b c d e f g h For the resin codes, ASTM International has replaced the three-arrow symbol by a solid, equilateral triangle because "the code is designed for resin-identification purposes and not recyclability".[6] The three-arrow symbol was based on the Universal Recycling Symbol.
