Availability of recycling facilities
Use of the recycling symbol in the coding of plastics has led to ongoing consumer confusion about which plastics are readily recyclable. In most communities throughout the United States, PETE and HDPE are the only plastics collected in municipal recycling programs. Some regions, though, are expanding the range of plastics collected as markets become available. (Los Angeles, for example, recycles all clean plastics numbered 1 through 7.)
Possible new codes
In 2007, a State Senate bill in California (SB 898) proposed adding a “0” code for compostable polylactic acid. However, this provision of the bill was removed before passage.
