Plastic Recycling: 7 Types Of Plastic And How To Recycle Them

Sometimes it seems like everything we own is made from plastic. Plastic is in our cars, packaging, toys, storage, kitchen utensils, and so on.

The problem is, it’s filling up our oceans and clogging up landfills. A 2016 study found that 32% of our plastic ends up in the ocean.[1]

Many of our plastic can be easily recycled, but with all the different rules and symbols, it can be really confusing and quite difficult to figure out what each symbol means and how to recycle it. 

You will probably have seen the universal plastic resin symbol (3 arrows chasing each other forming a triangle) but what you may not know is the number in the middle denotes a certain type of plastic, and how it can be recycled. 

At Vegums, we’re passionate about creating a sustainable world, so we do everything we can to help reduce plastic pollution. We wrote this plastic recycling guide to help anyone unsure how to recycle something, so we can help stop more plastic from going into a landfill.

Symbol Number 1 – PET or PETE

Plastic recycling PET symbol

PET or PETE stands for Polyethylene Terephthalate and is the most common plastic used for single-use bottled drinks. It’s lightweight, inexpensive, and can easily be recycled. 

Even though this type of plastic can be easily recycled, recycling rates are only around 20%.

What’s it used in:
PET or PETE is a clear, strong, and lightweight plastic that is widely used for packaging foods and beverages, especially convenience-sized soft drinks, juices, and water.

How to recycle it?
94% of UK councils will now collect PET plastic either from your recycling bin or from recycling centres. They do suggest removing bottle lids and putting them in the regular bin as they are often a mixture of different plastics. 

Where does it go?
PET/PETE can be used to make many new products, including new plastic bottles, clothing, industrial strapping, sheet and film, and automotive parts. 

Symbol Number 2 – HDPE

PVC cannot be recycled, so ask your local waste management to see if you should put it in the trash or drop it off at a collection centre.

Symbol Number 4 – LDPE

LDPE stands for Low-Density Polyethelene. This plastic has many applications but is only just becoming more recyclable. In the UK, you can put this in your recycle bin, but you may have to check with your local council to see if this is recycled.

LDPE is used mainly in film applications for both packaging and non-packaging applications, as well as plastic carrier bags.

How to recycle it?
Number 7 plastics can be several different types, and therefore are not recyclable.

As number 7 plastics are not recycled, we can try to upcycle them where possible. Examples such as water bottles can be re-used, and food containers re-used for meal prep. They can also be created into plastic lumber.
