The symbol belong to the SPI (Society of
Plastic Industry) resin identification codingsystem, developed in 1988.

Most plastics can be recycled, but they have tobe separated into their different polymer types.
Because of the difficulty and expense ofsorting, collecting, cleaning and reprocessing,at the moment it is only economically viable to
recycle PETE and HDPE. Thermoplastics can be remelted, but
thermosetting plastics can only be crushed andused as insulation.

The symbols used in the code consist of arrows that cycleclockwise to form a rounded triangle and enclosing a
number.
When the number is not there, the symbol is known as theuniversal Recycling Symbol, indicating generic recyclablematerials.
In this case, other text and labels are used to indicate thematerial used. Previously recycled resins are coded with an"R" prefix (e.g, a PETE bottle made of recycled resin could
be marked as RPETE using same numbering).

1 = PET or PETE = Polyethylene Teraphthalate. Commonuses: soft drink bottles, some fruit juices, alcohol
beverage bottles.
2 = HDPE = High
density polyeth
ylene. Common uses:(clear HDPE) milk jugs, distilled water, large vinegar
bottles, grocery bags; (colored HDPE) liquid laundry and
dish detergent, fabric softener, motor oil, antifreeze,
bleach and lotion.

3 = V = Vinyl/Polyvinyl Chloride. Common uses: vegetable
oil bottles, mouthwash, salad dressings.
4 = LDPE = Low density polyethylene. Common uses:
bags for dry cleaning, bread, produce and trash and for
food storage containers.

5 = PP = Polypropylene. Common uses: battery cases,
dairy tubs, cereal box liners.
6 = PS = Polystyrene. Common uses: yogurt cups, clearcarryout containers, vitamin bottles, fast food, spoons,
knives and forks, hot cups, meat and produce trays, egg
cartons, clamshell carryout food containers.

7 = Other types of plastics. Plastics labeled with a seven (7)
are made from a type other than the six most common types
listed above or they can be made from multiple layers of
different types of plastics. Common uses: squeezableketchup bottles, most chip snack bags, juice boxes (individual
servings).

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, 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
