Plastic recycling is a complex process, and not all plastics are created equal when it comes to their ability to be recycled. The numbers and symbols on plastic products are resin identification codes, indicating the type of plastic, not its recyclability. While all plastics are technically recyclable, some are more commonly recycled than others, and the methods and facilities available differ by region.
| Characteristics | Values |
|---|---|
| Recyclability of plastics with resin identification codes #1 and #2 | Most commonly recycled plastics |
| Recyclability of plastics with resin identification codes #3, #4, #5, #6, and #7 | Tougher to recycle and not universally collected |
| Plastic with resin identification code #1 | PETE or PET, used for soda, water, and other drink bottles, cooking oil containers, plastic peanut butter jars, etc. |
| Plastic with resin identification code #2 | HDPE, used for milk jugs, shampoo bottles, cleaning product containers, detergent bottles, plastic shopping bags, etc. |
| Plastic with resin identification code #3 | PVC, used for sewage pipes and synthetic window frames |
| Plastic with resin identification code #4 | LDPE, used for soft plastics like cling film, plastic dry cleaner covers, carry bags, and grocery bags |
| Plastic with resin identification code #5 | PP, used for plastic furniture, jerry cans, car parts, and bottle tops |
| Plastic with resin identification code #6 | Polystyrene, commonly known as Styrofoam, used for fast food containers |
| Plastic with resin identification code #7 | Miscellaneous plastics like polycarbonates, polylactides, and nylon, as well as biodegradable plastics. Often labeled as "Other" |
| General recyclability of plastics | Depends on local recycling programs and facilities |
| Plastic bags | Should not be put into recycling bins as they can get tangled in the equipment |

What You'll Learn
Recycling symbols and their meanings
While all plastics can be recycled, not all plastics are accepted by local recycling programs. The recycling symbol found on plastic products does not indicate that a product is necessarily recyclable. Instead, the number inside the triangle symbol, known as a resin identification code, tells you what kind of plastic the material is made of.
Plastics that have #1 (PETE) or #2 (HDPE) are the most commonly recycled plastics. PETE is used to make bottles for soda, water, and other drinks, while HDPE is used to make milk jugs, shampoo bottles, and detergent bottles. HDPE is one of the easiest plastic polymers to recycle and is accepted worldwide.
Plastics #3, #4, #5, #6, and #7 are generally tougher to recycle and are not as widely collected in local recycling programs. For example, plastic bags made of type #4 plastic should not be put into recycling bins as they can get tangled in the equipment. Other types of hard-to-recycle plastics include Styrofoam, shrink wrap, and manufacturing scrap, which require specialized handling.
In addition to the standard resin identification codes, there are other recycling symbols that indicate specific instructions or attributes of the packaging. For instance, the Green Dot symbol, used in some European countries, indicates that the producer has made a financial contribution towards the recovery and recycling of packaging, but it does not guarantee that the packaging is recyclable or will be recycled. The chasing arrows symbol, on the other hand, is the universal recycling symbol, indicating that the item can be recycled, while the seedling symbol indicates that an object is compostable.

Plastic resin identification codes
The presence of a resin code on a plastic product does not necessarily mean that the product can be recycled. The number inside the triangle indicates the type of plastic the product is made from. Plastics with RICs "1" and "2" are the most commonly recycled plastics and are accepted in most local recycling programs. Type 1 plastic, or PETE, is used for beverage bottles, cups, and other packaging, while Type 2 plastic, or HDPE, is used for bottles, cups, milk jugs, and detergent bottles. These types of plastic are widely recycled because they are easy to process and have a high value.
Plastics with RICs "3," "4," "5," "6," and "7" are generally tougher to recycle and are not universally collected in local recycling programs. Type 3 plastic, or PVC, is used for pipes, siding, and flooring, while Type 4 plastic, or LDPE, is used for plastic bags, six-pack rings, and tubing. Type 5 plastic, or PP, is used for auto parts, industrial fibres, and food containers. Type 7 plastic includes products made from multiple plastic resins or a type of plastic resin that didn't fit into the other categories.
It's important to note that the acceptability of plastic products for recycling can vary from city to city and state to state. Some states in the United States require the usage of RICs to identify the type of resin used in plastic products, while others have different requirements for the codes and labelled containers. It is always recommended to check with local municipalities or recycling facilities to confirm which plastic materials can be recycled in your community.

Plastic recycling complexities
Plastic recycling is a complex process, and not all plastics are recyclable. The recycling symbol found on plastic products does not indicate that a product can be recycled; rather, the number inside the triangle is a resin identification code that tells you what type of plastic the material is made of.
Plastics with codes #1 (PETE) and #2 (HDPE) are the most commonly recycled plastics and can be tossed into standard recycling bins. HDPE is one of the easiest plastic polymers to recycle and is accepted worldwide. Most recycling companies will collect HDPE materials and take them to large facilities to be processed.
However, plastics with codes #3, #4, #5, #6, and #7 are generally tougher to recycle and are not universally collected in local recycling programs. For example, PVC (code 3), polystyrene (code 6), and polyurethane and polycarbonate (code 7) are some of the most problematic plastics. These plastics often contain potentially toxic chemicals and are difficult to recycle or reuse. As a result, they require specialized handling or, ideally, should be replaced with safer and more reusable alternatives.
Other factors that contribute to the complexity of plastic recycling include the need to separate different types of plastics, such as HPDE film from LDPE film and clear films from coloured or printed films, and the challenge of properly cleaning plastic items before recycling them. Food residue on plastic items can contaminate other recyclables, such as paper and cardboard, and affect the recycling process. Therefore, it is important to properly follow the guidance of recycling symbols and local regulations to ensure effective plastic recycling.

Plastic recycling contamination
- Reducing recycling rates: Contamination can lead to materials that could have been recycled being sent to landfills instead. For example, bottles and cans can get lodged in film wrap or plastic bags, causing them to be diverted from the recycling process.
- Damaging machinery: Certain materials, such as plastic bags, can jam or break sorting and recycling equipment.
- Creating safety hazards: Some contaminants, like medical or electronic waste, pose risks to the health and safety of recycling workers.
- Decreasing the value of recyclables: Food residue, oil, and grease on recyclables can reduce their quality and make it harder to sell the recycled materials.
- Undermining collective efforts: Even a small amount of contamination can render a large batch of recyclables non-viable, wasting the efforts of those who sorted their waste correctly.
To avoid plastic recycling contamination, it is important to separate different types of plastics and other materials, such as paper, glass, and metal. It is also crucial to empty and rinse containers to remove food residue and liquids before placing them in the recycling bin. Additionally, individuals should refer to their local guidelines, as the recyclability of certain plastics can vary depending on the city or state.

Plastic recycling processes
Plastic recycling is a complex process. The first step is the collection of plastic materials from homes and institutions. This is typically done by placing recycling containers in public places, where people can deposit their plastic waste. The more plastic that is collected, the more material there will be for the recycling process.
The next step is sorting. This is done by colour or thickness and can be done by machine or by hand. Sorting is vital as it identifies the correct processes to recycle the plastics. Most recycling machines can only recycle one type of plastic at a time. Further separation is also required for some plastics, such as HDPE film from LDPE film, and clear films from coloured or printed film.
After sorting, the plastic is washed to remove impurities such as dirt and organic residue. This is done using several methods, including friction washers, which are cost-effective and require less labour.
Once clean, the plastic is then shredded into smaller pieces before being reused. The final stage of the process is reprocessing by melting, and producing new products from the recycled plastic.
There are several different types of recycling processes. Mechanical recycling is the most common approach and involves processing plastic waste into secondary raw materials or products without significantly changing the material's chemical structure. Chemical recycling is a growing approach that changes the chemical structure of plastic waste. This includes pyrolysis, where polymers are heated in the absence of oxygen to break them down into smaller parts.
