Plastic recycling symbols are not a guarantee of recyclability. The number inside the chasing arrows triangle identifies the type of plastic and helps determine the proper disposal or recycling method. Local authorities do not all collect the same materials, so it is important to research and understand your town's legislation and rules for recycling. Some plastics are traditionally not recycled, so it is best to consult your municipality's website for specific instructions. Additionally, recycling symbols do not take into account the presence of food or product residue, which can contaminate other materials during the recycling process. Understanding the meaning behind these symbols can help reduce waste, limit your carbon footprint, and protect the environment and marine life.

What You'll Learn
Recycling symbols indicate the type of plastic resin used, not recyclability
Plastic recycling can be confusing, and it is important to understand the different symbols and what they mean. Firstly, it is worth noting that not all packaging will have a recycling label, but this does not mean it cannot be recycled. Recycling symbols indicate the type of plastic resin used, identified by a 'Resin Identification Code', and not necessarily whether the item can be recycled.
The ''chasing arrows' symbol, also known as the Mobius symbol, is the classic three arrows in a circle, often with a number in the middle. This number, from 1 to 7, indicates the type of plastic resin used, with each number corresponding to a different type of plastic. For example, PET or PETE (number 1) is used for drinks bottles and is widely recycled, whereas PVC (number 3) is used for car parts and is not easily recyclable.
It is important to understand the different symbols and the processing needs of different plastics. Some plastics have higher melting points, and some are made from multiple types of plastic, which makes them harder to recycle. It is also worth noting that different municipalities have different recycling capabilities and guidelines, so it is important to check what is accepted locally. Some plastics may be recycled at specialist points or stores, and some may need to be taken to a recycling centre.
Additionally, it is good practice to rinse recyclable packaging to prevent food residue from contaminating other materials, and to separate different types of plastics and materials, such as removing lids and caps, which may not be recyclable.

Recycling symbols show how to dispose of an item
Recycling symbols are a useful way to understand how to dispose of an item. They appear on many everyday items and help identify how different types of packaging can be recycled. However, it's important to note that not all packaging will have a recycling label, but this does not mean it cannot be recycled.
Recycling symbols can indicate whether an item can be recycled, how to dispose of it, or if it is made from recycled material. They also identify the type of plastic resin used in the item's manufacture through a 'Resin Identification Code'. This is represented by a ''chasing arrows' symbol surrounding a number between 1 and 7, which defines the resin used. For example, PET or PETE (polyethylene terephthalate), represented by the number "1", is used for drinks bottles and some food packaging and is widely recycled.
It is important to understand your local area's rules for recycling to know what can and cannot be recycled in specific bins. This is because different areas may have different ways of recycling certain materials. For example, some materials may be recycled through curbside programs, while others may need to be dropped off at a collection center.
Some items may have multiple codes if they are made from multiple types of plastic or other materials. In addition to the plastic resin codes, these symbols are mandatory for products sold in the European Union.
Other symbols may indicate that an item should not be placed in a waste bin, such as electrical items, which can be recycled through retailers or at recycling centers. The universal recycling symbol, with its three chasing arrows, represents the concept of "reduce, reuse, recycle," and is easily recognized worldwide.

Some plastics are harder to recycle, like PVC and LDPE
If a plastic item doesn't have a recycling symbol, it doesn't necessarily mean that it can't be recycled. However, it's important to understand your local recycling rules and regulations to ensure that you're properly informed about what can and cannot be recycled in your area. You can do this by checking your town or city's website or contacting their waste management department.
Now, regarding plastics that are harder to recycle, like Polyvinyl Chloride (PVC) and Low-Density Polyethylene (LDPE), there are a few things to note. Firstly, PVC is one of the oldest types of plastic and is commonly used in pipes, flooring, and medical equipment. It contains harmful chemicals, which make it challenging to recycle. PVC is rarely accepted in curbside collection programs due to the difficulty in processing it. When it is recycled, it is typically used in flooring, paneling, and roadside gutters.
LDPE, on the other hand, is often used in plastic bags, plastic wraps, and squeezable bottles. It has a simple structure that makes it easy to produce but difficult to recycle. LDPE tends to tangle in recycling machinery, disrupting the recycling process. Some recycling programs do accept LDPE, but it is not widely accepted in curbside recycling bins. When LDPE is recycled, it can be transformed into bin liners, packaging films, and other products.
It's worth noting that the recyclability of plastics can vary depending on the region and the availability of specialized recycling facilities. Additionally, some plastics may be technically recyclable but are not widely recycled due to economic factors or the presence of other, more easily recyclable materials.

Check local recycling rules and what your municipality accepts
Recycling programs vary from community to community. So it's important to check your local municipality's rules and accepted materials. This is because certain materials may not be recycled in your area, and some materials may need to be recycled separately. For example, some areas may require different types of materials to be collected in separate bins (multi-stream recycling), while others may accept different types of materials in the same bin (single-stream recycling).
You can check which materials are accepted by your local recycling program by visiting your community's recycling website or checking distributed information. Some resources that can help you determine if a package is recyclable in your area include the Recycling Locator tool, where you can enter your postcode, and the Earth911 website, where you can search for "household hazardous waste collection" near your zip code. Additionally, you can contact your local recycler or recycling provider directly to ask about specific materials or packages.
It's important to understand the recycling symbols designated for each type of plastic, as different plastics have varying processing needs and are recycled into different products. However, the existence of a plastic resin code on a product does not guarantee that it is recyclable in your area. Always check with your local recycling program or provider to find out which types of plastic they accept. For example, plastic bottles are the most commonly recycled plastic products, but other plastics may or may not be accepted in your area.
Some general guidelines for recycling common materials include rinsing recyclable packaging to prevent food residue from contaminating other materials and ensuring that plastic, metal, and glass materials are empty before recycling. Additionally, caps and lids under 40mm in diameter are too small to be captured for recycling, so it's recommended to put the lid back on the bottle packaging to increase the chance of it being recycled. It's also important to note that some materials, such as Styrofoam and egg cartons, may or may not be accepted by your local recycler, so always check first.

Rinse plastic to avoid contaminating other materials
It is important to rinse plastic containers before recycling them to avoid contaminating other materials. While recycling facilities have robust cleaning processes in place, it is still important to ensure that plastic containers are relatively clean. This is because plastic is easily contaminated, and even the residue from a label can alter its chemistry and affect the quality of the final recycled material.
The main material that is sensitive to contamination is paper. This is particularly the case now that many recyclers have moved to "single stream" recycling, where glass, plastic, paper, and cardboard are collected together and no longer need to be sorted into separate bins. Therefore, it is important to remove any food or product residue from plastic containers before recycling them, especially if they are collected with paper. Liquids, in particular, should be rinsed out, although solids such as peanut butter are also important to remove.
It is also beneficial to rinse plastic containers before recycling to deter rats and insects from trying to get at the recyclables before pickup. In addition, rinsing plastic containers can help to preserve the water benefits of recycling. While it is important to be mindful of water usage, prudent rinsing is not likely to negate the water savings of recycling plastics.
It is worth noting that not all plastic can be recycled, and it is important to check the symbols on plastic items to understand if and how they can be recycled. These symbols can indicate whether an item can be recycled, how to dispose of it, or if it is made of recycled material. It is also important to understand your town's legislation and rules for recycling, as some materials may not be recycled in certain areas.

Frequently asked questions
Not all packaging will have a recycling label, but this doesn't mean it can't be recycled. The recycling symbol is based on what the majority of local authorities collect or do not collect. It is important to research and understand your town's legislation and rules for recycling so that you know what can and cannot be recycled in certain bins.
Glass is typically recyclable even without the symbol. Acrylic and polycarbonate, which fall under Symbol 7 plastics, aren't always recyclable but can often be repurposed due to their thermoplastic properties.
The recycling symbols on plastic indicate the type of plastic and help determine the proper disposal or recycling methods. For example, Symbol 1, or PETE, represents polyethylene terephthalate, which is commonly used for soft drink bottles, mineral water containers, fruit juice containers, and cooking oil containers.
Yes, there are several misconceptions about plastic recycling. For example, the Resin Identification Code (RIC) system was created by and for the plastics industry to tell recycling facilities what type of resin is in an object, but it does not guarantee that the item will be recycled. Additionally, while recycling symbols indicate that an object is capable of being recycled, they do not mean that it will be accepted in all recycling collection systems or that it has been recycled.
