The Reasons Why Some Plastic Can’t Be Recycled

The Reasons Why Some Plastic Can’t Be Recycled

Some plastics can be recycled, whilst some can’t.

There’s many reasons some plastics can’t be recycled, but we’ve listed and explained some of them below.

 

1. It’s A Non Recyclable Plastic

Let’s start with the obvious reason – some types of plastic are recyclable whilst others aren’t.

There can be a number of reasons for this.

 

2. Chemical Make Up Of The Plastic

Some plastics just don’t have the chemical make up to be processed in a recycling plant.

It’s usually specific types of plastic that can be recycled, and also harder or rigid plastics compared to the single use soft plastics.

 

If we take PVC for example – the chlorine atoms in it make it hard to recycle.

3. It’s Already Been Recycled Too Many Times

Different plastics lose durability and quality as they are recycled – this is due to the shortening and weakening of the fibres that make up the plastic.

A weaker and lower quality plastic either won’t meet the standard of performance it needs to, or won’t have as much economic value.

 

4. It Can’t Be Mixed With Other Plastics

Because of chemical make up, some plastics just can’t be mixed with others.

This is an issue for recycling, especially single stream recycling – where different types of plastic are collected together.

 

5. The Product The Plastic Is Used In Makes It Hard To Recycle

Some products are designed and manufactured in a way that doesn’t allow for recycling.

 

  • A sports drink, for instance, can have three different and incompatible types of plastic in the bottle, the shrink-wrapped film, and the lid. All three components can be individually recycled but they are rarely separated other than by shredding.

  • [another example is] black plastic trays. Their only function is to amplify the colour of a product, yet they also prevent recycling as sorting machines cannot detect black pigment.

6. It Doesn’t Make Economic Sense/It’s Not Profitable

Because of the value of the plastic material, the cost to recycle, the market demand or value of the recycled product, or a number of other economic reasons – some plastics just aren’t profitable or economically viable to recycle (compared to landfill or other options).

 

7. Recycling Facilities, & Recycling Technology & Equipment Differs From Region To Region

Not all recycling facilities work the same way or have the same capabilities.

Different localities, states, and countries can have different recycling technology and facilities.

Some can recycle some types of plastic and plastic products that others can’t.

 

8. Recycling Facilities Or Recycling System As A Whole Need Upgrading Or Change

Usually a problem specific to developing countries.

Some developing countries lack a proper waste collection and management system altogether, so there is a high amount of plastic that doesn’t get collected, and ends up on the land, in rivers and eventually in the ocean.

 

9. Contamination

Contaminated plastic, usually with food waste or food scraps, usually can’t be recycled.
