Recycling LDPE (#4) plastic

Are you familiar with LDPE or number 4 plastic? If not, then we will discuss it here.

First off, LDPE is an abbreviation of the plastic Low-Density Polyethylene. IT is considered a thermoplastic manufactured from the monomer ethylene. It is known for being a transparent kind of plastic, as well as being tough and flexible.

For us to get a better grasp of LDPE, I will first give you a general background on all types of plastic. Basically, there are 7 types of plastics. The number is a resin identification code that helps recycling facilities sort out the different kinds of plastics. You won’t have a problem determining what they are because manufacturers of different kinds of products usually print out an item’s recycling symbol number. But nevertheless, let me give you a general background of the plastic types before moving on to LDPE below.


Different kinds of plastics

It is hard to determine whether a plastic item is recyclable or not. The product might have a “recyclable” label engraved on it, but that does not mean your local council will accept them right away. It is best to contact local authorities first before putting a plastic product in the kerbside recycling bin.

With that being said, it is still important to know the different kinds of plastic before jumping straight to LDPE recycling to give you a better understanding of what to – and not to – recycle. Here are the different plastic types. Additionally, I will classify them based on how easy or difficult it is to recycle each one type:


Easier ones

  • PET or Polyethylene Terephthalate – most commonly found in soda, water and juice bottles
  • HDPE or High-Density Polyethylene – milk jugs, household carpet cleaner and detergent containers – and also some plastic bags


Moderate ones

  • PVC or Polyvinyl Chloride – plumbing pipes, windows, and in some cases, cooking oil and shampoo bottles
  • LDPE or Low-Density Polyethylene – frozen food containers, condiment bottles and shopping – even produce bags
  • PP or Polypropylene – Tupperware boxes, medicine bottles and ketchup bottles


Harder ones

  • PS or Polystyrene (what we commonly know as Styrofoam) – takeaway coffee cups and egg cartons
  • Mixed Plastics or Other Plastics


We made a blog on recycling numbers that you can also read if you want more information on the different types of plastic.

Now that I have discussed the different kinds of plastics, you can now know what you should and should not recycle. In saying this, let us move on to the next topic, which is recycling LDPE plastic. Even though it is not as common as recycling type 1 and 2 plastic, LDPE plastics are now getting more traction because of many consumers buying products that contain such plastic.

In recycling your LDPE products, here is what you should do:

Ask for instructions first from your local council before doing anything else. If they accept LDPE for recycling, then you can go ahead and put them in the kerbside recycling bin. Follow the instructions laid out by your local waste authority. Furthermore, if they do not accept such plastics, there are other alternatives who can help you. One example is REDcycle, where they accept different kinds of plastics – including LDPE 4 – they can recycle. You only need to collect them and drop them off at the given locations; REDcycle has partnered up with many Australian supermarkets that you can choose from.

Important Note: As of 9 November 2022, REDcycle is on a temporary pause. 

And, remember to always collect them in bulk if you wish to recycle them. Remove their labels and other unnecessary non-plastic parts before recycling LDPE.

See our blog on waste recycling Sydney.


LDPE recycling: conclusion

Remember that the higher the recycling symbol number, the less chance of the plastic product being recycled in your local waste facilities. But, good news: LDPE recycling number 4 is slowly getting more recognised as something that is commonly recycled. And it is not farfetched to say that in the future, we can fully recycle all kinds of plastics with ease.
