The system has been adopted by a growing number of communities implementing recycling programs, as a tool to assist in sorting plastics. In order to deal with the concerns ofPrint/export recyclers across the U.S., the RIC system was designed to make it easier for workers in materials [citation needed] recoveryCreate a book and recycling facilities to sort and separate items according to their resin type.

In 2008, ASTM International took over the administration of the RIC system and eventually issued ASTM D7611—Standard Practice for Coding Plastic Manufactured Articles for Resin Identification.[3] In 2013 this standard was revised to change the graphic marking symbol of the RIC from the "chasing arrows" of the Recycling Symbol to a solid triangle instead.

Since its introduction, the RIC has often been used as a signifier of recyclability, but the presence of a code on a plastic product does not necessarily indicate that it is recyclable any more than its absence means the plastic object is [necessarily] unrecyclable.

Consumer confusion [edit]

In the United States, use of the RIC in the coding of plastics has led to ongoing consumer confusion about which plastic products are recyclable. When many plastics recycling programs were first being implemented in communities across the United States, only plastics with RICs "1" and "2" (polyethylene terephthalate and high-density polyethylene, respectively) were accepted to be recycled. The list of acceptable plastic items has grown since then,[1] and in some areas municipal recycling programs can collect and successfully recycle most plastic products regardless of their RIC. This has led some communities to instruct residents to refer to the form of packaging (i.e. "bottles", "tubs", "lids", etc.) when determining what to include in a curbside , rather than instructing them to rely on the RIC.[8] To further alleviate consumer confusion, the American Chemistry Council launched the "Recycling Terms & Tools" program to promote standardized language that can be used to educate consumers about how to recycle plastic products.[9]

Possible new codes [edit]

Modifications to the RIC are currently being discussed and developed by ASTM's D20.95 subcommittee on recycled plastics.[10]

In the U.S. the Coalition has also created a "How2Recycle" [11] in an effort to replace the RIC with that aligns more closely with how the public currently uses the RIC. Rather than indicating what type of plastic resin a product is made out of, the four "How2Recycle" indicate whether a plastic product is

Widely Recycled (meaning greater than 60 percent of the U.S. can recycle the item through a curbside recycling program or municipal drop-off location). Limited (meaning only 20–60 percent of the U.S. can recycle the item through a curbside recycling program or municipal drop-off location). Not Yet Recycled (meaning less than 20 percent of the U.S. can recycle the item through a curbside recycling program or municipal drop-off location). Store Drop-Off (meaning the item can be recycled if brought to participating store drop-off locations, typically at grocery stores).

The "How2Recycle" labels also encourage consumers to check with local facilities to see what plastics each municipal recycling facility can accept.

Computing [edit]

The different resin identification codes can be represented by Unicode icons (U+2673), (U+2674), (U+2675), (U+2676), (U+2677), (U+2678), and (U+2679). (U+267A) is the portion of the symbol without the number or abbreviation.
