Plastic products are often marked with symbols and numbers that indicate the type of plastic they are made from. These markings are not mandatory, but they are useful for recycling purposes, helping consumers identify the appropriate disposal route for plastic products. The markings are also important for understanding a product's makeup and influencing decisions concerning its handling, waste recovery, or disposal. While some plastics are widely recycled, others are difficult to recycle and can be harmful to the environment.

What You'll Learn
Plastic identification codes
There are seven categories of plastic identification codes, each with a number and acronym. These include:
- PETE or PETG (also known as PET): This stands for polyethylene terephthalate and is commonly used for soft drink bottles, water containers, and cooking oil containers. It is widely recycled and has one of the highest recycling market values.
- HDPE: This stands for high-density polyethylene and is one of the most commonly used plastics in the United States. It is widely accepted by recycling programs and can be reused in packaging and household products.
- PVC: This plastic is known for its durability and resistance to harsh conditions, making it popular in construction, plumbing, and transport. However, it has been known to leach chemicals, so it is not suitable for food use, and its recycling is challenging due to a lack of facilities and a limited market for recycled PVC.
- LDPE: This plastic is used for most soft plastic products globally. It is lightweight and relatively less toxic, making it suitable for food use, but its flimsy nature often limits it to single-use applications. LDPE is not widely accepted in kerbside collections due to sorting and recycling difficulties.
- PP: Polypropylene plastic is marked with the number five and the acronym PP. It is known for its durability, strength, and lightweight nature, making it ideal for furniture, luggage, toys, and car parts. It is considered safe for reuse as it is unlikely to leach chemicals.
- PS: This stands for polystyrene or styrene plastic and is marked with the number six and the acronym PS. It is commonly used in toys, packaging, cosmetic bags, and vending cups. While not widely accepted in curbside recycling, it can be recycled into egg cartons and takeout containers.
- OTHER: This category, marked with the number seven, includes various plastics such as acrylic, polycarbonate, polyurethane, polypropylene, polylactic fibers, nylon, and fiberglass. It is essential to check with local recycling programs for specific guidelines on recycling these plastics.
The identification codes are enclosed within reversed angled brackets, " < > ", with the appropriate abbreviated terms for the specific plastic type. These codes help consumers identify safer plastics and determine the appropriate disposal methods for different plastics. While there is currently no mandatory requirement to mark plastics, organizations like the BPF recommend using identification codes for larger parts and packaging to aid in recycling efforts.

Plastic recycling symbols
The most common recycling symbol is the "chasing arrows" triangle, with a number or acronym inside it. For example, Symbol 1 with the acronym PETG (also known as PETE or PET) represents polyethylene terephthalate, which is commonly used for soft drink bottles, water containers, and cooking oil containers. This type of plastic is easily recyclable and has one of the highest recycling market values. Symbol 2, with the acronym HDPE, indicates high-density polyethylene, which is one of the most commonly used plastics in the United States and is widely accepted by curbside recycling programs.
Other symbols include PP or polypropylene plastic, marked with the number 5 and the acronym PP. This plastic is known for its durability, strength, and lightweight properties, making it ideal for ketchup bottles, medicine bottles, and car parts. Styrene plastic, also known as polystyrene (PS), is marked with Symbol 6 and is commonly used in toys, refrigerator trays, cosmetic bags, and vending cups. While polystyrene is not widely accepted in curbside recycling programs, it can be recycled into new products such as egg cartons and takeout containers.
Finally, Symbol 7, marked with the word "OTHER," represents other plastics that do not fall into the previous categories, such as acrylic, polycarbonate, polyurethane, nylon, and fiberglass. It is important to note that not all plastics can be recycled, and some, like PVC, polystyrene, polyurethane, and polycarbonate, are considered problematic due to their potential toxicity and difficulty in recycling.
To aid in recycling, organizations like the BPF and PlasticsEurope recommend using identification codes on larger plastic parts and packaging. The ISO 11469:2016 standard provides a uniform system for labeling plastic products by their material components, using symbols and abbreviated terms to indicate the type of plastic and any fillers or additives.

How to identify different types of plastic
Plastic symbols are a standardised communication system that conveys important information about a product's material composition, recyclability, and proper handling. These markings are essential tools that promote sustainability, ensure safety, and support the proper handling and disposal of plastics.
There are three primary international standards that work together to create a comprehensive plastic identification system:
- ISO 11469: Provides a universal system for marking plastic products using abbreviated material names, such as "PP" for polypropylene or "PET" for polyethylene terephthalate.
- ISO 1043: Complements ISO 11469 by categorising plastics based on their polymer types, additives, and fillers.
- Resin identification codes: These are the seven plastic codes that indicate the type of plastic and provide recycling and reuse information. For example, a "3" on a water bottle means it is made from polyvinyl chloride (PVC), while a "5" indicates polypropylene, and these plastics are not usually accepted by public recycling centres.
Additionally, plastic types can be identified through their physical characteristics:
- PE: Feels smooth, soft, and tough, with obvious marks after being scratched. It is extensible and bendable.
- PP: Feels smooth, without marks after being scratched. It is bendable and has great tensile strength and rigidity.
- MDPE and HDPE: Hard, with great rigidity and toughness. They are milky white, translucent, and waxy when uncoloured, floating in water, and tasteless and odourless.
- PVC: Soft and tough, with a sticky feel. It is yellowish, translucent, and glossy. Its hardness is higher than low-density polyethylene but lower than polypropylene.
- ABS: Hard, tough, rigid, and not easy to break. It appears milky white or beige, amorphous, opaque, and dull. It sinks in water and is tasteless and odourless.
Another method to identify plastics is by their density, or "gravity dressing". This method leverages the different densities of plastic types and their floating/sinking behaviours in water. However, it is rarely used alone but rather in conjunction with other methods for accurate identification.

What different recycling symbols mean
Markings on plastic, also known as plastic codes, are used to identify the type of plastic a product is made from. This helps to determine the appropriate disposal route for plastic products. While these markings are not mandatory, they aid in recycling.
Symbol 1: PET or PETE/PETG
This symbol is usually accompanied by the acronym PET, PETE, or PETG and stands for polyethylene terephthalate. It is commonly used for soft drink bottles, water containers, fruit juice containers, and cooking oil containers. This type of plastic is easily recyclable and is one of the most widely recycled plastics in the world. It can often be recycled curbside and used to make new containers, carpets, and furniture.
Symbol 2: HDPE
The number 2 symbol indicates high-density polyethylene, one of the most commonly used plastics in the United States. It is widely accepted by curbside recycling programs and is often reused in packaging, furniture, and household products. HDPE can be recycled up to 10 times, making it a durable and reusable option.
Symbol 5: PP
Polypropylene plastic, marked with the number 5 and the acronym PP, is known for its durability, strength, and lightweight nature. It is used in a variety of products, including furniture, luggage, toys, ketchup bottles, medicine bottles, and car parts. PP is increasingly being accepted in curbside recycling programs.
Symbol 6: PS
Styrene plastic, also known as polystyrene, is marked with the number 6 and the acronym PS. This type of plastic is commonly used in toys, packaging, refrigerator trays, cosmetic bags, jewelry, and vending cups. While it is not widely accepted in curbside recycling programs, it can be recycled into new products such as egg cartons and takeout containers.
Symbol 7: OTHER
The number 7 symbol represents the "other plastics" category, which includes plastics such as acrylic, polycarbonate, polyurethane, polylactic fibers, nylon, and fiberglass. These plastics do not have a specific code and are often burned instead of recycled. However, some types of plastic under this category, such as acrylic and polycarbonate, can be recycled and repurposed.
It is important to note that not all plastics are recyclable, and the recycling symbols do not guarantee recyclability. These symbols primarily help identify the type of plastic and guide proper disposal or recycling methods.

How to recycle plastic
Plastic is one of the most versatile and popular materials of modern times, with 300 million tonnes of plastic being produced worldwide each year. Recycling plastic helps conserve natural resources, reduce waste, save energy and create jobs.
However, not all plastics are recycled, and some types still go to landfill or are incinerated. Plastic bags should not be combined with other recyclables and are often collected separately at special drop-off locations.
- Plastic bottles are usually made from PET or HDPE, which are easy to recycle. Rinse and empty the bottles, keep the lids on, and twist on the bottle caps before tossing them in the bin.
- Plastic bags and wraps can often be recycled at grocery stores and other retail locations. These include plastic carrier bags, bread bags, and bags for dry cleaning, produce, and newspapers.
- Plastic containers for products such as yogurt, sour cream, and condiments, as well as "clamshell" packaging, can be recycled. Check with your local recycler to see what specific types of plastic they collect.
- Plastic bottle caps are recyclable, but it is important to empty the bottles before recycling. Bottle caps are typically made from polypropylene plastic, which can also be used for auto parts, bike racks, and storage bins.
- Look out for public recycling bins at public parks, sports stadiums, and beaches. If you can't find a bin, take your recyclables back home and dispose of them in your home bin.
- Check for products made with recycled plastic to help save this valuable material from going to waste. For example, PET plastic has one of the highest recycling market values and can be turned into new products of similar quality.
- Plastic codes or symbols can help you identify the type of plastic and determine if it is recyclable. For example, Symbol 1 with the acronym PETG or PETE is widely recycled and commonly used for soft drink bottles and water containers. Symbol 2, or HDPE, is one of the most commonly used plastics and is also widely accepted for recycling.
