Plastic recycling is a complex and often confusing topic. Most plastic products bear the general recycling symbol, a triangle of three arrows, with a number from 1 to 7 inside indicating the type of plastic. However, this number system serves little purpose for consumers, and different locations have varying recycling capabilities. Symbols provide insight into how to recycle an item, but it is crucial to understand your town's specific rules. Some plastics are rarely recycled, like PVC, while others, like PET, are more common and easier to recycle. It is important to understand the symbols and local regulations to ensure proper disposal and recycling.

The Green Dot symbol does not mean packaging is recyclable, only that the producer has contributed to recovery and recycling efforts
Recycling symbols are a helpful way to identify how different types of packaging can be recycled. However, not all packaging will have a recycling label, and this doesn't mean that it can't be recycled. Symbols can indicate whether an item can be recycled, how to dispose of it, or if it's made from recycled materials.
The Green Dot symbol is one such recycling symbol. Despite its name, the Green Dot does not indicate that packaging is recyclable. The symbol is used on packaging in some European countries and signifies that the producer has made a financial contribution towards the recovery and recycling of packaging in Europe. The Green Dot is a protected trademark in the UK, but it does not generally have much meaning for UK consumers. The symbol is mandatory in France, Germany, Portugal, and Spain, and voluntary in most of the rest of Europe.
The Green Dot symbol is not to be confused with the Mobius Loop, which signifies that a product or its packaging is capable of being recycled. However, the presence of the Mobius Loop does not guarantee that the material has been previously recycled or will be recycled upon disposal. The Mobius Loop may contain a percentage figure, which represents the amount of packaging made from recycled materials.
Other recycling symbols include the Corrugated Recycles symbol, which can be used to promote the recycling of corrugated cardboard and to indicate that it is recyclable. The Aluminium symbol, a circle of arrows with 'alu' in the centre, indicates that an item is made from recyclable aluminium, which can be recycled repeatedly without losing quality. The Steel symbol indicates that an item is manufactured from steel, is magnetic, and is widely recyclable. The Compostable symbol, or the 'seedling' symbol, indicates that items can be recycled through garden waste collections but should not be put into normal household waste.

The number in the triangle on plastic indicates the type of plastic
Plastic recycling symbols, also known as resin identification codes, are found on various plastic items and help identify the type of plastic resin used in the product. These symbols are usually moulded into the bottom of the plastic product and look like a triangle of chasing arrows with a number inside, ranging from 1 to 7. The number within this triangle is a classification that indicates the type of plastic used, with each number representing a different type of plastic resin.
The presence of this symbol on a plastic product does not necessarily mean that the item can be recycled, but rather, it provides information about the possibility of recycling. The number classifications help determine the appropriate disposal route for different plastic products. For example, Symbol 1, with the acronym PETE or PET, represents polyethylene terephthalate, which is commonly used for soft drink bottles, mineral water containers, fruit juice containers, and cooking oil containers. This type of plastic is easily recyclable and is often part of curbside recycling programs.
Symbol 2, with the acronym HDPE, indicates high-density polyethylene, which is commonly used for containers such as milk jugs, detergent bottles, and soap bottles. HDPE is one of the safest and most commonly recycled plastics, accepted by many curbside recycling programs. On the other hand, Symbol 3, often with the letter "V", represents PVC or polyvinyl chloride, a soft and flexible plastic. PVC is rarely recycled and is not usually part of curbside recycling programs.
Symbol 4, LDPE, indicates low-density polyethylene, which is used for shopping bags, crushed bottles, and shrink wraps. This type of plastic is not commonly recycled but can be converted into floor tiles and other products. Symbol 5, PP, represents polypropylene, a durable and lightweight plastic used in furniture, toys, and packaging. It is increasingly being accepted in curbside recycling programs. Finally, Symbol 6, PS, stands for polystyrene, which is used in disposable cups, take-away containers, and meat trays. Symbol 7, with the acronym O (for "other"), includes polycarbonate (PC), acrylic (PMMA), and all other types of plastics that don't fit into the previous categories.

Local authorities do not all collect the same materials, so check with your local recycler
Recycling symbols are a useful way to identify how different types of packaging can be recycled. However, it's important to remember that local authorities do not all collect the same materials for recycling. The labels you see on packaging are based on what the majority of local authorities collect or do not collect.
For example, in the UK, the recycling label is applied to packaging collected by 75% or more of local authorities. This means that if you see a particular recycling symbol on a product, it is likely that your local authority will collect it for recycling. However, it's always a good idea to check with your local recycler to be sure.
Different types of plastics are identified by the small number inside the triangle of the "chasing arrows" symbol. For instance, the number "1" with the acronym PETE or PETG represents polyethylene terephthalate, which is commonly used for soft drink bottles and is easily recyclable. On the other hand, PVC plastic, identified by the number "3" and the letter "V", is rarely recycled and is not usually part of curbside recycling programs.
To find out what specific materials your local authority collects, you can check printed materials or the website of your local government or recycling provider. You can also use online tools, such as the Recycling Locator tool mentioned on the Recycle Now website, where you can enter your postcode to find out what you can put in your home recycling bin. Additionally, some materials, like compostable plastics, may be recycled with your garden waste through your local authority.

Some plastics are rarely recycled, like PVC, polystyrene, polyurethane and polycarbonate
Recycling symbols are a helpful way to identify how different types of packaging can be recycled. However, not all packaging will have a recycling label, and even if it does, it does not always mean that it will be accepted in all recycling collection systems or that it can be recycled. For example, the "chasing arrows" symbol is often mistaken as an indicator that the product is recyclable, but the number inside the triangle is what helps identify the type of plastic used for the product.
Some plastics are rarely recycled, like PVC, polystyrene, polyurethane, and polycarbonate. PVC, or polyvinyl chloride, is marked by symbol 3 with the letter "V". It is used in bubble foils and trays for sweets and fruit, and its lightweight and rigid properties make it easily stamped, sawed, punched, nailed, riveted, or bonded. However, it is rarely recycled and is not usually part of curbside recycling programs. In rare instances, it can be recycled for speed bumps, roadway gutters, and cables. Polystyrene, also known as composite plastic, is another material that is not often recycled. Polyurethane and polycarbonate are also non-recyclable plastics.
The recyclability of different plastic types depends on how they are made. Thermoset plastics contain polymers that form irreversible chemical bonds and cannot be recycled, whereas thermoplastics can be remelted and remolded. Mechanical recycling and chemical recycling are the two main ways to recycle plastic. In mechanical recycling, plastic is washed, ground, and melted, while in chemical recycling, plastic is broken down into monomers to form new polymers to be reused.
The low recycling rates of plastics are concerning, as plastic waste is a significant contributor to polluted oceans, overextended landfills, and ecological damage. Despite efforts to improve recycling, such as legislation banning single-use plastics and "bottle bills" that incentivize customers to return plastic bottles, plastic production is increasing, and most plastic ends up in landfills.

The recycling code can be used by consumers to distinguish between safer plastics
Recycling symbols are present on a variety of everyday items, from soft drink cans to plastic toiletry bottles, and they help us identify how different types of packaging can be recycled. The presence of a recycling symbol, however, does not necessarily mean that the product can be recycled. It is the number inside the triangle, known as the resin code, that is important as it corresponds to a different type of plastic.
On the other hand, PVC, represented by the number 3, is rarely recycled and is not usually part of curbside recycling programs. LDPE, identified by the number 4, is also not typically recycled but can be converted into floor tiles and shipping envelopes. It is important to note that while these recycling codes provide guidance, the regulations for displaying plastic recycling symbols are inadequate, with codes often being small, difficult to find, or hard to read.
By understanding the number classifications, consumers can make more informed choices about the types of plastic they use and their appropriate disposal methods.

Frequently asked questions
Not all packaging will have a recycling label, but this doesn't mean you can't recycle it.
The most common recycling symbol is the "`chasing arrows'" or "Mobius" symbol, which is a triangle formed by three circling arrows. The number inside the triangle (1-7) indicates the type of plastic.
There are six common types of plastic: PET or PETE (1), HDPE (2), PVC (3), LDPE (4), PP (5), and PS (6). There is also a miscellaneous category with the number 7.
This symbol is commonly found on single-use bottled beverages, such as soft drinks, water, ketchup, and beer bottles, as well as mouthwash bottles, peanut butter containers, and salad dressing.
The Green Dot symbol does not indicate that the packaging is recyclable or will be recycled. Instead, it signifies that the producer has made a financial contribution towards the recovery and recycling of packaging in Europe.
