Plastic products are often stamped with a number inside a small triangle made of arrows. This number is a resin code that identifies the type of resin used to produce the plastic, and also indicates how the product might be recycled. The numbers range from 1 to 7, with 1 and 2 being the most widely accepted by recycling centres, and 6 and 7 being rarely recycled. However, it's important to note that recycling programs vary from city to city, so it's always best to check with your local municipality.

- Number 6 plastics are made with polystyrene (Styrofoam) and are difficult to recycle
Types 1 and 2 plastics are widely accepted by most recycling centres
Plastic is one of the most complicated materials to recycle. This is partly because consumers don't know which types of plastic can be disposed of and how. It is also because of the environmental, economic, and technical challenges associated with recycling plastic.
There are seven types of plastic, each with a unique resin code, a number between one and seven inside a small triangle made of arrows. The presence of a resin code does not necessarily indicate recyclability; it is the number inside the triangle that matters. The general rule is that the lower the number, the more likely the plastic is to be recycled.
However, it is important to note that the recyclability of plastics may vary depending on your municipality's guidelines. Some areas may not permit certain plastic types in recycling bins, and hard-to-recycle plastics like Styrofoam may require specialized handling.

Number 3 plastics are made with polyvinyl resin, commonly called PVC, and are not as easily recycled
Plastic products are often stamped with a resin code, which is a number between one and seven inside a small triangle made of arrows. The number inside the triangle is important because it indicates the type of plastic the product is made of. Types 1 and 2 plastics, such as PET or PETE and HDPE plastics, are the most commonly recycled plastics and can generally be placed in standard recycling bins.
However, plastics with the number 3 are made with polyvinyl resin, commonly called PVC, and are not as easily recycled. PVC is one of the oldest synthetic materials, first discovered in 1872, and is now commonly found in our homes in items such as flooring, gutters, window frames, fencing, tiles, and appliances. It is a soft, flexible plastic, and its lightweight, durable, and chemical-resistant properties make it a popular choice for manufacturers.
Despite its widespread use, PVC is not widely accepted by local recycling programs. This is partly due to the toxic nature of PVC when disposed of, and the lack of accessible recycling options for the general community. Additionally, PVC has a high chlorine content, and the process of recycling it requires separation from other plastics. Curbside recycling programs typically do not accept PVC items like pipes, window frames, or sidings. However, rigid PVC bottles or containers may be recyclable through your local curbside program, but it is important to check which types of plastics are accepted.
There are some specialist recyclers that can recycle specific types of PVC. For example, the Recofloor vinyl flooring take-back scheme in the UK, Ireland, and Australia accepts PVC flooring for recycling. Similarly, some countries have takeback schemes for vinyl windows. While recycling number 3 plastics is more challenging, these specialist programs offer viable options for properly disposing of and recycling PVC products.

Number 4 plastics are usually soft and flexible and include grocery bags, dry cleaning bags, and plastic food wrap
Plastic products are often stamped with a resin code, a number between one and seven inside a small triangle made of arrows. Each number corresponds to a different type of plastic. Number 4 plastics, or LDPE plastics, are usually soft and flexible. They include produce and grocery bags, dry cleaning bags, and plastic food wrap. LDPE stands for low-density polyethylene, which gives this resin a thinner and more flexible design. LDPE is also used to make the bags that hold newspapers, sliced bread loaves, and fresh produce, among other things.
LDPE products can sometimes be recycled. However, bags made of type 4 plastic should not be put into recycling bins because they can get tangled in the equipment at recycling facilities. Instead, grocery stores collect these bags for proper plastics recycling.
Other types of plastics that are soft and flexible include PVC and PP. PVC, or polyvinyl chloride, is the world's third-most widely produced synthetic plastic polymer. It can be manufactured to possess rigid or flexible properties. The softer and more flexible form of PVC is used in plumbing products, electrical cable insulation, clothing, and medical tubing. PP, or polypropylene, is one of the most flexible thermoplastics on the planet. It is also durable, heat-resistant, acid-resistant, and cheap, making it ideal for laboratory equipment, automotive parts, medical devices, and food containers.

Number 5 plastics are made of polypropylene and are a flexible hard plastic like food containers, screw-on caps, and butter tubs
Plastic products are often stamped with a resin code, which is a number between one and seven inside a small triangle made of arrows. This number indicates the type of plastic the product is made of, with each type having different properties and recyclability. Number 5 plastics, also known as PP plastics, are made of polypropylene. This type of plastic is lightweight, sturdy, and heat resistant, making it ideal for various packaging applications, particularly food packaging. It is commonly used for products such as food containers, screw-on caps, and butter tubs.
Polypropylene is widely used due to its advantageous properties. It offers good protection from moisture and chemicals, and it can handle high temperatures. This means that it can be bent and twisted without losing its shape. Additionally, it is approved by the FDA for both single and repeated-use food containers. It is also considered a safe plastic by the EPA, as no studies have shown a direct correlation between polypropylene and cancer in humans. However, more research is needed to understand the potential impact of polypropylene microplastics on human health and the environment.
Number 5 plastics are recyclable, and they can be identified by the number 5 in the chasing arrows symbol or the letters "PP." Many curbside recycling programs accept rigid plastic products made from polypropylene, such as plastic bottles or tubs. However, most programs do not accept flexible PP products like bags or soft packaging. It is important to check local guidelines, as some areas may have specific rules or drop-off points for recycling soft plastics.
While number 5 plastics are recyclable, it is important to note that not all recycling facilities accept all types of recyclable plastics. Additionally, some plastics that are technically recyclable may still be difficult to process, such as Styrofoam. Therefore, it is always important to check with local recycling programs to understand their specific capabilities and guidelines.

Number 6 plastics are made with polystyrene (Styrofoam) and are difficult to recycle
Plastic products are often stamped with a number, which is a resin identification code that indicates the type of plastic the product is made of. The presence of a resin code does not necessarily mean that the product can be recycled. The numbers range from 1 to 7, with each number corresponding to a different type of plastic. Number 6 plastics are made with polystyrene (Styrofoam) and are difficult to recycle.
Polystyrene is known for its inability to biodegrade, and many city recycling programs do not pick up or process #6 plastics through single-stream household curbside collection services. However, some areas may have styrofoam recycling available, so it is worth checking with local recycling centers to confirm. When expanded polystyrenes are recycled, they cannot be used for food containers anymore but can be utilized to create outdoor furniture, roofing tiles, and coat hangers.
The difficulty in recycling polystyrene is due to its low density, with an average of 98% air. It must be shipped to a facility where it can be compressed to be cost- and time-effective for transfer over long distances. This process adds complexity and cost to the already intricate and challenging task of recycling plastics.
Recycling facilities are expensive to build and operate, requiring large volumes of plastic to be treated daily to be profitable. Small quantities of specific plastics, like polystyrene, can make recycling non-economical due to low efficiency and high costs. Additionally, polystyrene is often used in food containers, and plastics can be contaminated by food residues, making the resins unsuitable for reuse.
Overall, while number 6 plastics made with polystyrene (Styrofoam) are challenging to recycle, it is still worthwhile to check with local recycling centers and properly prepare and clean the plastic items to maximize the chances of successful recycling.
