Plastic is a widely used material, and its proper disposal is essential for reducing waste. However, the recycling process can be confusing, and what is recyclable in one community may not be in another. Hard plastics, such as those found in water bottles, food containers, and toys, are generally more widely accepted by recycling facilities due to their durability. To determine if a hard plastic item is recyclable, you can perform the scrunch test to assess its flexibility and rigidity, and check for a recycling symbol and number, usually a triangular resin code with a number between 1 and 7.

What You'll Learn
Hard plastics are generally more widely recycled
Recycling plastic can be confusing, and what is recyclable in one community might be trash in another. Hard plastics, such as those used in water bottles, food containers, and toys, are typically made from materials like PET (Polyethylene Terephthalate) or HDPE (High-Density Polyethylene). These types of plastics are generally more widely recycled due to their durability and the demand for recycled materials in manufacturing.
To determine whether a plastic item is recyclable, you can perform the scrunch test. This involves attempting to scrunch or bend the plastic item with your hands. If it is hard plastic, it will resist bending or scrunching. You may find it difficult or impossible to deform the plastic. Soft plastics, on the other hand, will easily scrunch or bend under pressure. Examples of soft plastics include plastic bags, cling wrap, and flexible packaging.
Another way to determine if a hard plastic item is recyclable is by checking its recycling symbol and number. Most plastic items are marked with a triangular resin code with a number between 1 and 7. For example, #1 (PET) is widely accepted for recycling and is found in water bottles, soda bottles, and some food packaging. #2 (HDPE) is also widely accepted and is used in milk jugs, detergent bottles, and toys. Plastics numbered #3-#7, such as PVC, LDPE, and PP, may be recyclable but may not be accepted by all recycling programs.
It is important to note that some types of plastics are not accepted in community recycling programs, so it is always good to check with your local recycling provider to learn which items they accept. Additionally, while compostable plastics are not intended for recycling, they can be disposed of through a community composting program or at a designated drop-off location.

Recycling symbols and numbers
- PET (Polyethylene Terephthalate): This type of plastic is commonly found in water bottles, soda bottles, and some food packaging. It is widely accepted for recycling and is marked with the number "1".
- HDPE (High-Density Polyethylene): This plastic is used in milk jugs, detergent bottles, and toys, and like PET, it is also widely recycled. It is identified by the number "2".
- PVC, LDPE, PP, and others: These plastics are marked with the numbers 3-7. While some are recyclable, they may not be accepted by all recycling programs.
It is important to note that not all recycling programs accept the same types of plastic. Therefore, it is essential to check with your local recycling program to determine which types of plastic they accept. Additionally, some plastics, like compostable plastics, should not be mixed with non-compostable plastics as they can contaminate the recycling stream.
Other common recycling symbols include:
- The Green Dot: This symbol does not indicate that the packaging is recyclable, will be recycled, or has been recycled. Instead, it signifies that the producer has made a financial contribution towards the recovery and recycling of packaging in Europe.
- The Forest Stewardship Council (FSC) logo: This identifies wood-based products from well-managed forests that are independently certified by the FSC.
- The "Seedling" logo: This indicates that a product is certified to be industrially compostable according to European standards.
- The "Do Not Litter" symbol: This symbol, often featuring a crossed-out bin, is used by Keep Britain Tidy to discourage littering.
By understanding these recycling symbols and numbers, you can make more informed decisions about how to recycle or dispose of plastic items responsibly.

The scrunch test
Take the plastic item you want to test. Pick up the item and attempt to scrunch or bend it with your hands by applying pressure. If the plastic is rigid or hard, it will resist bending or scrunching. You may find it difficult or impossible to deform the plastic. Such plastics are generally more widely accepted by recycling facilities due to their durability and the demand for recycled materials in manufacturing. On the other hand, if the plastic is soft, it will easily bend or scrunch under pressure.
However, it is important to note that the scrunch test is just one of the ways to determine if a plastic item is recyclable. Other identification methods include checking recycling symbols and numbers. Most plastic items are marked with a triangular resin code with a number between 1 and 7. For example, #1 (PET) is widely accepted for recycling and is found in water bottles, soda bottles, and some food packaging, while #2 (HDPE) is used in milk jugs, detergent bottles, and toys, and is also widely recycled.

Plastic resin codes
The Resin Identification Code (RIC) is a technical standard with a set of symbols that appear on plastic products to identify the type of plastic resin used to make the product. The RIC was developed in 1988 by the Society of the Plastics Industry (now the Plastics Industry Association) in the United States. The original RIC consisted of arrows that cycle clockwise to form a triangle that encloses a number. Subsequent revisions to the RIC have replaced the arrows with a solid triangle, but the old symbols are still in common use. The numbers inside the triangles are known as plastic resin codes and they range from 1 to 7.
The plastic resin codes are as follows:
- Polyethylene terephthalate (PET): This is the most widely recycled plastic in the world and is used in a lot of food containers. It is also used in plastic bottles and has one of the highest recycling market values.
- High-density polyethylene (HDPE): This is another widely recycled plastic worldwide and is one of the few plastics that is likely to have an onshore recycling centre. It is a durable, hard plastic that is most commonly used for cleaning or personal care products.
- Polyvinyl chloride (PVC): PVC is a durable plastic that is not easily impacted by sunlight, water, or other harsh conditions.
- Low-density polyethylene (LDPE)
- Polypropylene (PP)
- Polystyrene (PS)
- Other plastics: This includes bioplastics, composite plastics (like crisp wrappers), plastic-coated wrapping paper, and polycarbonate (which contains BPA).
It is important to note that the RIC does not indicate whether a product is recyclable. It simply tells you what type of plastic a container is made from.

Understanding Plastic Types
First, it's crucial to distinguish between hard and soft plastics. Hard plastics are typically found in items like water bottles, food containers, and toys. They are usually made from materials such as PET (Polyethylene Terephthalate) or HDPE (High-Density Polyethylene). On the other hand, soft plastics include plastic bags, cling wrap, and flexible packaging.
Local Recycling Program Variations
Recycling programs can differ significantly from one community to another. Some communities may have specific drop-off locations or guidelines for certain types of plastics. For instance, compostable plastics should not be mixed with non-compostable plastics and might require separate disposal methods. Always check with your local program to understand their specific rules and accepted materials.
Identifying Recyclable Plastics
Most plastic items have a triangular resin code with a number between 1 and 7, indicating their recyclability. Numbers 1 (PET) and 2 (HDPE) are the most commonly accepted for recycling and include items like water bottles, soda bottles, milk jugs, and detergent bottles. Numbers 3 to 7, such as PVC, LDPE, and PP, may be recyclable but might not be accepted by all recycling programs. Familiarize yourself with these numbers to make informed decisions about what can be recycled in your area.
The Scrunch Test
If you're unsure whether an item is made from hard or soft plastic, you can perform the scrunch test. Simply try to scrunch or bend the plastic with your hands. If it's hard plastic, it will resist deformation, while soft plastic will easily scrunch or bend. This test, along with checking the recycling symbols and numbers, can help you make more responsible disposal decisions.
