Plastic recycling is a complex process. Less than 10% of plastic waste generated worldwide has ever been recycled. One of the barriers to recycling plastic is a lack of awareness of the seven plastic recycling symbols, each of which represents a different type of plastic with distinct recycling instructions. The plastic recycling codes are known as Resin Identification Codes (RIC) and were introduced in the 1980s to inform plastic manufacturers of the type of plastic a container is made from. The RICs are numbers 1 through 7 inside the chasing arrows symbol, which is the universal symbol for recycling. Understanding these codes helps consumers decipher if a product is recyclable and choose between different packaging options.

Recycling codes help consumers identify which plastics are safer to use
Recycling codes are essential for consumers to identify safer plastics for use. The seven plastic recycling codes indicate the different types of plastics and their distinct recycling instructions. The Mobius symbol with a number inside (1 through 7) is the symbol for Plastic Resin Identification Codes. Each number represents a different type of plastic, with specific processing criteria such as melting temperatures and the final product it can be recycled into. For example, HDPE (High-Density Polyethylene), represented by the number 2, is a durable, hard plastic with a high melting point, commonly used for cleaning products and personal care products. It can be recycled multiple times, making it a safer choice for consumers who want to reduce their environmental impact.
Understanding these codes is crucial for effective segregation of plastics during the recycling process. Different types of plastics have varying processing needs, and some may be more challenging to recycle than others. For instance, plastics with the code 3, such as PVC, are considered problematic due to their potential toxicity and difficulty in recycling. Polystyrene, with the code 6, is another example of a plastic that some states in the US have moved to prohibit due to its environmental impact. By checking the recycling codes, consumers can make informed choices about the types of plastics they use and their potential recyclability.
The presence of recycling codes empowers consumers to make environmentally conscious decisions. For instance, consumers can actively choose products packaged in #1 plastics, such as PET bottles for soft drinks, as they are widely recycled and have a high recycling market value. Additionally, understanding these codes helps consumers avoid products that are difficult to recycle, reducing the risk of recycling contamination. This contamination occurs when non-recyclable items are placed in recycling bins, causing additional time and monetary costs for processors, who may then send the entire bag of items to landfills.
Recycling codes also enable consumers to support companies that prioritise sustainability. For example, some companies, like Eco Plastics in the UK, are working with major brands to produce rPET bottles, which are made from recycled PET. By recognising these recycling codes, consumers can actively contribute to a more circular economy, reducing the environmental impact of plastic waste.

The seven plastic codes help consumers know which products are safe to recycle
The seven plastic codes, known as Plastic Resin Identification Codes (RIC), help consumers identify which plastic products are safe to recycle. Each of the seven codes represents a different type of plastic, with distinct recycling instructions. The RIC tells manufacturers what type of plastic a container is made from, but does not address recyclability. Therefore, consumers must understand the seven codes to know which products are safe to recycle.
The seven codes are:
- PET: PET is one of the most commonly used plastics in consumer products, found in most water and soda bottles, and some packaging. It is widely recycled and has one of the highest recycling market values. It can be recycled onshore and turned into products of similar quality and form.
- HDPE: HDPE is another widely recycled plastic, used for cleaning or personal care products. It is a durable, hard plastic that can withstand most solvents. It has a high market value and can be recycled multiple times.
- PVC: PVC is a durable plastic that is resistant to sunlight, water, and other harsh conditions. It is difficult to recycle and is considered hazardous.
- LDPE: LDPE is considered less toxic than other plastics and is relatively safe for use. It is not commonly recycled, but this is changing as more programs gear up to handle this material. When recycled, LDPE is used for plastic lumber, landscaping boards, and floor tiles.
- PP: PP is considered safe for reuse. It is used for items like yogurt cups, ketchup bottles, and plastic bottle caps. Some curbside recycling programs accept PP, but it is important to check locally.
- PS: Polystyrene (PS) can be made into rigid or foam products, the latter known as Styrofoam. It is difficult to recycle and is considered a possible human carcinogen. Most places do not accept it for recycling.
- Other: Code 7 is a miscellaneous category that includes polycarbonate (PC) and other plastics. There is no standardised reuse or recycling protocol for this category. Products in this category may contain potentially toxic chemicals, and there is a risk of chemical leaching into food or drink products.
Understanding these seven codes helps consumers know which products are safe to recycle and make informed choices between different packaging options.

Recycling codes help consumers choose between different packaging options
Recycling codes are an important tool to help consumers make informed choices about the products they buy and the packaging these products come in. The seven different plastic codes indicate the type of plastic used, with each type having distinct recycling instructions and processing needs. For example, some plastics have different melting temperatures, and they are ultimately recycled into different products. This means that understanding the recycling symbols helps consumers to separate their waste effectively.
The chasing arrows symbol, designed in 1970, was originally intended to inform consumers that a product was recyclable. However, this symbol is often mistaken for an indication of recyclability, which is not always the case. The resin identification code (RIC), denoted by a number inside the chasing arrows symbol, tells manufacturers what type of plastic a container is made from. While the RIC does not address recyclability, it can help consumers decipher if a product is recyclable and make informed choices about the packaging they buy.
For example, consumers are encouraged to select products packaged in #1 plastics, as these can be widely recycled. #1 plastics, or PET, are used in a lot of food containers and have one of the highest recycling market values due to their ability to be turned into products of similar quality. On the other hand, plastics with a code of 3, 6, or 7 are considered more problematic and difficult to recycle. PVC (code 3), polystyrene (code 6), and polyurethane and polycarbonate (code 7) are mentioned as some of the most challenging plastics to recycle.
It is important to note that the recyclability of a product also depends on the capabilities of the local recycling facilities. Therefore, consumers should check their municipality's recycling guidelines to understand which types of plastic can and cannot be recycled in their area. By understanding the recycling codes and local guidelines, consumers can make more sustainable choices and ensure that their plastic waste is recycled properly.

Recycling codes help plastic manufacturers identify the type of plastic a container is made from
Recycling codes are an essential tool to help plastic manufacturers identify the type of plastic a container is made from. Known as Resin Identification Codes (RIC), these codes were introduced in the 1980s, following the creation of the chasing arrows symbol in 1970, which indicated that a product was recyclable. While the arrows symbol was intended for consumers, the RIC was designed to be recognised by waste sorting facilities.
The RIC consists of a triangle of arrows with a number inside, ranging from 1 to 7, each representing a different type of plastic. For example, PET bottles for soft drinks are labelled with a 1, while plastic containers and pipes are labelled with a 2. PVC, which is a durable plastic used for sewage pipes and window frames, is labelled with a 3. LDPE, a soft plastic used for cling film and bags, is labelled with a 4.
These codes are particularly useful for identifying plastics that are difficult to recycle. For instance, PVC (code 3), polystyrene (code 6), and polyurethane and polycarbonate (both code 7) are considered some of the most problematic plastics due to their potential toxicity and inability to be recycled. By using these codes, manufacturers can identify these challenging plastics and separate them from those that are more easily recyclable, such as PET and HDPE.
Understanding the different types of plastics through these codes is crucial for effective recycling. Different plastics have varying processing needs, such as different melting temperatures, and are ultimately recycled into different products. Therefore, by using the RIC, manufacturers can ensure that plastics are correctly sorted and processed according to their specific requirements.

Recycling codes help consumers understand the specific processing criteria for different plastics
Recycling codes are an essential tool to help consumers understand the specific processing criteria for different plastics and ensure effective recycling. The seven plastic recycling codes, ranging from 1 to 7, indicate distinct types of plastics with unique recycling instructions. For example, Type 1 plastics, such as PET bottles for soft drinks, and Type 2 plastics are generally accepted in standard recycling bins. However, other types, like Styrofoam (polystyrene, code 6) and PVC (code 3), are more challenging to recycle and may require specialised handling or fall under local prohibitions.
The codes serve as a guide to consumers, helping them distinguish between plastics that can be recycled and those that should be disposed of properly. This distinction is crucial, as non-recyclable items in recycling streams can create additional challenges and costs for processors, sometimes leading to entire bags of items being sent to landfills. By understanding the codes, consumers can make informed choices, reducing the risk of contamination in the recycling process.
Additionally, recycling codes provide valuable information about the specific processing needs of different plastics. Each type of plastic has unique characteristics, such as varying melting temperatures, which must be considered during the recycling process. For instance, HDPE (high-density polyethylene), denoted by code 2, is a durable, hard plastic that can withstand most solvents. As a result, it is widely recycled and has a high market value, finding applications in cleaning or personal care products and even milk bottles.
The presence of recycling codes empowers consumers to make environmentally conscious choices. By understanding the codes, consumers can opt for products packaged in more recyclable materials, such as Type 1 plastics, which can be widely recycled and turned into products of similar quality. This awareness encourages consumers to support companies that use recycled materials, like Coca-Cola's partnership with Eco Plastics to produce rPET bottles in the UK.
In summary, recycling codes are a powerful tool for consumers to decipher the complex world of plastic recycling. They provide critical information about the specific processing criteria, recyclability, and environmental impact of different plastics. By understanding these codes, consumers can make informed decisions, contribute to effective recycling practices, and ultimately reduce the environmental footprint of plastic waste.
