Recycling: Numbers, Codes, Chart, Resin, BPA

recycle-numbersRecycling the materials helps to maintain the ecological balance.

We can reuse or recycle things those are identified through certain numbers.

These numbers are centered inside chasing arrows by clockwise. These are called the recycling numbers. Usually, these numbers are mostly found on the body of plastic things such as…

  • Toys
  • Bags
  • Bins
  • Cars
  • Packages etc.

Recycling symbols can be also in a different color along with recycling numbers. The scale of the recycling numbers is between 1-7.

These numbers show the idea whether the product is recyclable, reusable or not.

This also lets the buyers or users the concept of buying recycled products.

Recycling Numbers/Codes

Different countries have different types of recycling codes. Resin Identification Code (RIC) first appeared in 1988.

China has a different polymer identification system. They classified plastics into seven types and have five separate symbols for post-consumer paths.

They also have 140 identification codes of plastics.

Numbers or codes can be unfamiliar but the target of these recycling numbers or codes is always the same.

Table of Resin Codes

The ASTM International Resin Identification Coding System is popularly known as RIC. This RIC is a set of symbols those speak about the ingredients of the plastic products. The Plastics Industry Association has developed the Resin Codes in 1988. ASTM International is an administration this from 2008.

Recycling number Image Alternate image #1 Alternate image #2 Abbreviation Polymer name Uses Recycling
1 PETE or PET Polyethylene terephthalate Polyester fibers (Polar Fleece), thermoformed sheet, strapping, soft drink bottles, tote bags, furniture, carpet, paneling and (occasionally) new containers. (See also: Recycling of PET bottles) Picked up through most curbside recycling programs.
2 HDPE or PE-HD High-density polyethylene Bottles, grocery bags, milk jugs, recycling bins, agricultural pipe, base cups, car stops, playground equipment, and plastic lumber Picked up through most curbside recycling programs, although some allow only those containers with necks.
3 PVC or V Polyvinyl chloride Pipe, window profile, siding, fencing, flooring, shower curtains, lawn chairs, non-food bottles, and children’s toys. Extensively recycled in Europe;481,000 tonnes in 2014 through Vinyl 2010 and VinylPlus initiatives.
4 LDPE or PE-LD Low-density polyethylene Plastic bags, six-pack rings, various containers, dispensing bottles, wash bottles, tubing, and various molded laboratory equipment LDPE is not often recycled through curbside programs, but some communities will accept it. Plastic shopping bags can be returned to many stores for recycling.
5 PP Polypropylene Auto parts, industrial fibres, food containers, and dishware Number 5 plastics can be recycled through some curbside programs.
6 PS Polystyrene Desk accessories, cafeteria trays, plastic utensils, toys, video cassettes and cases, clamshell containers, packaging peanuts, and insulation board and other expanded polystyrene products (e.g., Styrofoam) Number 6 plastics can be recycled through some curbside programs.
7 OTHER or O Other plastics, such as acrylic, nylon, polycarbonate, and polylactic acid (a bioplastic), and multilayer combinations of different plastics Bottles, plastic lumber applications, headlight lenses, and safety shields/glasses. Number 7 plastics have traditionally not been recycled, though some curbside programs now take them.

 

After 2013, ASTM revised the RIC symbols. Now they are identified as below:

Let’s have a brief idea about these above Resin Codes:

#Number one:

PET (Polyethylene Terephthalate)

This type of plastics is a very common form to be found in water and pop, soft drink bottles, peanut butter containers etc. These types of plastics are mostly used for the single-use purpose. PET plastic is recyclable but it is difficult to decontaminate.

#Number two:

HDPE (High-Density Polyethylene)

HDPE plastic is used to produce jugs; oil, detergent, bleach, shampoo bottles; toys and some plastic bags for the stiffness and heat-resistance. This is recyclable and reusable.

#Number three:

PVC (Polyvinyl Chloride)

PVC is the soft and flexible type of plastic. Manufacturers use PVC to produce food wrapper, oil bottles, computer cables, pipes, plumbing parts, siding, windows etc.  PVC made products are not recyclable.

#Number four:

LDPE (Low-Density Polyethylene)

Different wraps, clothing bags, squeezable bottles, bread bags etc. are made of LDPE plastics. LDPE plastic is less recyclable but always recyclable.

#Number five:

PP (Polypropylene)

You can see the presence of Polypropylene is disposable diapers, syrup and ketchup bottles, bottle caps, different containers, chips bags etc. PP is reusable but less recyclable.

#Number six:

PS (Polystyrene)

The use of Polystyrene is much significant for its affordability, lightweight nature, and the easy reformation. You can find PS in meat trays, cartons, aspirin bottles, CD cases etc.  Recycling of Polystyrene is less regular to happen.

#Number seven:

Other (BPA, Polycarbonate, and LEXAN)

The other types of plastics are used to make baby bottles, big water bottles, sunglasses, computer cases, sippy cups, car parts etc. These are not recommended for reuse.

Meaning of Recycling Symbol without Number:

There are also recycling symbols available those contain no number. These are not plastic. These are kind of descriptive text that illustrates the particular object.

Hewlett-Packard (HP) has a different type of recycling symbol which is indifferent to the “recyclable” symbol for plastic resins. There are two different pairs of the number in this symbol. First one says the minimum percentage of a percentage of post-consumer recycled content (in this case 50%), and the second one tells total recycled content (in this case 80%).

Blue colored chasing arrows is also a newly appeared symbol. The Green Dot, RBRC etc. symbols also contain no number like the RIC symbols.

Final Thoughts

Recycling numbers are developed with a great motive. A user should know what material he or she is using for daily uses. These materials can be paper, glass, metal, plastics etc. Recycling Codes or numbers allow getting the idea of reuse and recycling. A person should know the proper concept of this certain topic. This can lead to a healthy environment and a healthy life.
