Plastic products are typically labelled with a number from 1 to 7, known as the Resin Identification Code (RIC). This system was developed in 1988 by the Society of the Plastics Industry (SPI) to help standardise the materials used in different plastic products and to facilitate the recycling of post-consumer plastics. Each number represents a different type of plastic and how/where it can be disposed of. For example, plastic number 1, PET or PETE (polyethylene terephthalate), is considered safe with a low risk of leaching and is commonly used for drink and food containers. On the other hand, plastic number 2, HDPE (high-density polyethylene), is used for milk jugs, shampoo bottles, and cleaning supplies, and can be recycled into plastic fencing, picnic tables, and lawn chairs. It's important to note that not all resin codes are recyclable, and understanding these codes can help consumers make more informed choices about the recyclability of products.

What You'll Learn
Resin Identification Codes (RICs) are used to identify the type of plastic
The RIC system uses numbers 1-7 to identify different types of plastics. Number 1, or PET/PETE (polyethylene terephthalate), is commonly used for food and drink containers, bottles, combs, tote bags, and carpeting. Number 2, or HDPE (high-density polyethylene), is known for its protective fabrication and is used for packaging shampoo, milk, soap, detergents, and food/drink containers. Number 3 is PVC (polyvinyl chloride), used in plumbing pipes and tiles. Number 4 is LDPE (low-density polyethylene), a durable and flexible plastic used in grocery bags, sandwich bags, and squeezable bottles. Number 5 is PP (polypropylene), found in Tupperware, yogurt packaging, and butter containers, and known for its performance at low temperatures. Number 6 is PS (polystyrene), commonly known as Styrofoam. Number 7 is a miscellaneous category for plastics not included in 1-6, including BPA and polycarbonate (PC).
The RIC system helps recyclers sort and separate items according to their resin type, as plastics must be recycled separately to preserve the value of the recycled material. While RICs do not directly indicate recyclability, they can help consumers make informed choices about packaging and recycling. Additionally, foundational knowledge about RICs can assist in determining if a product is recyclable.

RICs are part of the Universal Recycling Symbol
The Plastic Industry Association (previously SPI) has implemented a plastic coding system that assigns a number from 1 to 7 to each plastic product, indicating its resin type. These numbers are known as Resin Identification Codes or RICs. The RICs are typically enclosed within the universal recycling symbol, which consists of three arrows chasing each other in a triangle formation, also known as the Möbius Loop.
The universal recycling symbol was originally designed in 1970 to indicate that a product could be recycled. However, the RICs within the symbol serve a different purpose. They identify the type of resin or plastic used to create the product, rather than indicating recyclability. This distinction is important because not all plastics with RICs are commonly recyclable.
The numbers 1 through 7 in the RIC system correspond to different types of plastics. Number 1, for example, represents PET or PETE (polyethylene terephthalate), commonly used for food and drink containers. Number 2 refers to HDPE (high-density polyethylene), often used for milk jugs, shampoo bottles, and cleaning supplies. Number 3 is for PVC (polyvinyl chloride), commonly found in plumbing. Number 4 represents LDPE (low-density polyethylene), used for storage bags and squeezable bottles. Number 5 is PP (polypropylene), found in Tupperware and yogurt packaging. Number 6 is PS (polystyrene), often called Styrofoam. Finally, number 7 is a miscellaneous category for plastics not covered by the previous codes, including polycarbonate (PC) and BPA.
While the RICs provide valuable information about the type of plastic, consumers should not assume that the presence of the universal recycling symbol guarantees recyclability. Recycling guidelines and capabilities vary by location, so it is essential to refer to local guidelines to determine if a specific plastic item can be recycled in your area.

RICs help recyclers sort materials effectively
The Plastics Industry Association (previously SPI) has implemented a plastic coding system that assigns a number from 1 to 7 to each plastic product, known as the Resin Identification Code (RIC). This system helps recyclers sort materials effectively by providing critical information about the plastic's resin composition.
The RIC system was introduced in the 1980s, featuring a triangular mark with a number, which indicates the type of plastic used in a container's fabrication. For example, the number 1 designates PET or PETE (polyethylene terephthalate), commonly used for food and drink containers, while number 2 refers to HDPE (high-density polyethylene), often used for packaging shampoo, milk, and detergents.
By understanding these codes, recyclers can effectively separate and process different types of plastic waste. This ensures compliance with environmental regulations and helps optimize recycling processes, reducing contamination and improving sustainability. Additionally, it empowers consumers to make informed choices, encouraging the selection of materials that are more recyclable or environmentally friendly.
However, it is important to note that the RIC system does not directly address the recyclability of a product. Consumers may mistakenly assume that a product bearing the chasing arrows symbol is recyclable, when in reality, the recycling process for plastics is complex and often ineffective. Despite the RIC system's potential to aid in sorting and processing, the responsibility of understanding these codes and properly recycling falls on consumers, leading to issues like recycling contamination.

RICs don't indicate recyclability
Plastic products are typically coded with a number from 1 to 7, which is known as the Resin Identification Code (RIC). Each number represents a specific type of plastic:
- PET or PETE (polyethylene terephthalate)
- HDPE (high-density polyethylene)
- PVC (polyvinyl chloride)
- LDPE (low-density polyethylene)
- PP (polypropylene)
- PS (polystyrene)
- Other (including polycarbonate, or PC)
These codes were developed in the 1980s to help plastic manufacturers and recyclers identify different types of plastic and sort their materials more effectively. However, it is important to note that RICs do not indicate the recyclability of a product. Here are four reasons why:
- RICs were created for the plastic industry, not consumers: RICs were originally developed for industry workers to identify different types of plastic. They were never intended to be consumer-facing recycle symbols or to provide recyclability instructions. In fact, guidelines for using RICs state that manufacturers should place them in unnoticeable places on packaging. This inconsistency can make it challenging for consumers to rely on RICs as a reliable guide for recyclability.
- RICs don't consider the entire package: While RICs may specify the type of plastic a container is made of, other parts of the package may not be recyclable. For example, a plastic container with an RIC may have a non-recyclable lid or label, leading to contamination in recycling facilities if not properly separated.
- Recyclability varies by community: Recycling guidelines and infrastructure can vary significantly from community to community. Some communities may specify which "number" plastics can be recycled, while others may provide images or lists of acceptable recyclables. This variation can make it challenging for consumers to rely solely on RICs to determine recyclability.
- The chasing arrows symbol can be misleading: The chasing arrows symbol, also known as the universal recycling symbol, has become symbolic of the act of recycling in popular culture. When combined with RICs, it further reinforces the misconception that an item with an RIC is recyclable. However, as previously mentioned, RICs only identify the type of plastic and do not indicate recyclability. To address this confusion, ASTM International replaced the chasing arrows symbol with a solid triangle in 2013. Despite this change, most states in the United States still require the use of the chasing arrows symbol with RICs, contributing to ongoing confusion.
In summary, while RICs are useful for identifying different types of plastic, they do not indicate the recyclability of a product. To determine if an item is recyclable, consumers should refer to additional sources of information, such as local recycling guidelines, the How2Recycle label, or specific instructions provided by recycling facilities.

RICs range from 1-7, with 7 being a miscellaneous category
The Resin Identification Code (RIC) is a system that helps identify different types of plastics and how/where they can be disposed of. The RIC was developed in 1988 by the Society of the Plastics Industry (SPI), now known as the Plastics Industry Association. The RICs are part of a broader set of recycling codes and are often mistaken for the recycling symbol. The original design featured a set of arrows in a triangle, which has since been replaced by a solid triangle to address consumer confusion. The numbers 1-7 inside the triangle indicate the type of plastic, with number 7 serving as a miscellaneous category.
Number 1 in the plastic coding system refers to items made with PET or PETE (polyethylene terephthalate). PET products include containers, bottles, jars, combs, tote bags, carpeting, and rope. PET is widely recycled and can be used for food and drink containers. Number 2 is HDPE (high-density polyethylene), which is also commonly recycled. HDPE is known for its protective fabrication and is used for packaging shampoo, milk, soap, detergents, and other food and beverage containers. Recycled HDPE is turned into fencing, crates, and lumber.
Number 3 is PVC (polyvinyl chloride), which is less commonly recycled than PET and HDPE. PVC is often used in plumbing pipes and tiles, and its applications vary based on hardness. Recycled PVC is used to make traffic cones, cables, flooring, park benches, and speed bumps. Number 4 is LDPE (low-density polyethylene), which is durable and flexible, and not widely recycled but is recyclable in certain areas. LDPE is used for plastic grocery bags, sandwich bags, and squeezable bottles. When recycled, LDPE is turned into household products, garbage cans, lumber, and furniture.
Number 5 is PP (polypropylene), found in Tupperware, yogurt packaging, and butter or margarine containers. It works well at low temperatures and is often recycled into ice trays, brooms, and bins. Number 6 is polystyrene (PS), commonly known as Styrofoam. Number 7, the miscellaneous category, includes a wide variety of plastics that are difficult to recycle, such as polycarbonate (PC) and BPA. Polycarbonate is used in CDs, DVDs, baby bottles, water bottles, and medical storage containers.
