Plastic Recycling Numbers

Plastic is among the greatest inventions. It is used in almost every small thing around us and has become an inseparable part of our daily life. Although plastic has benefited us in several ways, it has become one of the most dangerous things for the planet. This is because once it is created it cannot be destroyed. It can stay as it is for several years and will do irreparable harm to nature. Hence, to stop more production of plastic, the concept of recycling came into picture. There are different recycling procedures for different types of plastic. These types are denoted by numbers from 1 to 7. These numbers help in segregating different types of plastic according to their recycling procedure. They are called plastic recycling numbers.

What are Plastic Recycling Numbers

There are seven types of plastic and all these types are represented by seven numbers ranging from 1 to 7. Not all types of plastic can be recycled. With the help of recycling numbers which are sealed on the plastic articles you can find out whether it can be recycled or not. These numbers can be seen either on the back of the item or on its side. You can find the number inside the recycling symbol on the item.

Number 1: PET or PETE (Polyethylene Terephthalate)
Number 1 plastic is considered to be quite safe for nature. It is found in the soft drink, water, mouthwash and beer bottles. It can also be used as a container for peanut butter, vegetable oil and salad dressing. They can be easily recycled because of their soft, lightweight and porous nature. They can be recycled into furniture, tote bags, paneling, straps, fibers, polar fleece etc. This plastic is picked up by curbside recycling programs.

Number 2: HDPE (High Density Polyethylene)
Number 2 plastic is also considered to be safe for nature. This type of plastic is found in bottles of detergents, shampoo, motor oil, bleach, milk jugs, juice, etc. They can also be found as containers of yogurt, butter, cereal boxes etc. Recycling of plastic bottles can produce other articles like pens, containers, floor tiles, dog houses, tables, fencing, benches, oil bottles, drainage pipe, etc. It is picked up by curbside recycling programs.

Number 3: PVC (Polyvinyl Chloride)
Number 3 plastic is dangerous to nature as it is very rarely recycled and if it is burned it releases toxic substances which can be very dangerous. This plastic can be found in bottles of detergent, shampoo, cooking oil, window cleaner etc. It can also be used for food packaging, windows, piping, medical equipment, wire jacketing etc. It can be transformed into paneling, decks, roadway gutters, cables, speed bumps, flooring etc. They are rarely recycled hence, taken by very few plastic lumber makers. Hence, it is better to minimize the usage of these bad plastic.

Number 4: LDPE (Low Density Polyethylene)
Number 4 plastic is considered harmless to nature as it can be recycled. It can be used for many applications such as packaging of frozen food, bread, shopping bags, furniture, clothing, carpets etc. These plastics can be recycled to form trash cans and liners, paneling, lumber, shipping envelopes, compost bins, floor tiles, etc. Although they can be recycled, still they are not taken up by many curbside recycling programs.

Number 5: PP (Polypropylene)
Number 5 plastic can be recycled and hence, does not harm nature too much. It can be found in syrup bottles, caps, straws, ketchup bottles, medicine bottles, yogurt containers, etc. They can be recycled into signal lights, brushes, brooms, ice scrapers, racks, bins, trays, battery cables, etc. As this product has a high melting point it can be used to keep hot food. It can be accepted by curbside recycling programs.

Number 6: PS (Polystyrene)
Number 6 plastic comes under the category of plastic which should be avoided. It can be found in aspirin bottles, compact disc cases, disposable plates and cups, meat tray, carry out containers, etc. These recycling plastics can be transformed into switch plates, vents, rulers, insulation, foam packaging etc. These plastics are considered dangerous as they are believed to release toxins in the food. They are taken by some curbside programs for recycling.

Number 7: Miscellaneous
All the other types of plastic are included in this category. These plastic are harmful for nature as they cannot be recycled traditionally. They can be found in water bottles, bullet proof materials, sunglasses, computer case, DVDs, iPods, nylon, etc. They are recycled very rarely and can be transformed into plastic lumber, custom-made products etc. This is one of the most dangerousrecycling numbers. BPA or Bisphenol A can be leached by this number which can directly harm the endocrine and is very dangerous for the hormones.

From the above information we can make out that number 1, 2, 4 and 5 are the safe plastic recycling numbers. Rest of them are harmful for nature and are difficult to recycle. You should avoid the numbers which can be harmful for nature as well as your health. There are lots of benefits of recycling plastic and hence, it is very important for you to understand the significance of these numbers and should always check for them before buying any plastic product.
