Is Polystyrene Recycled? An Eco Guide

Polystyrene is a common plastic, with 15.6 million tons made every year. It’s used in food packaging, insulation, and as protective cushioning. Though it can be recycled, finding places to recycle it is hard. In 2020, the U.S. made 292 million tons of waste, with 146 million tons going to landfills. About 30% of this was Expanded Polystyrene (EPS).

The U.K. recycles over 100 tonnes of EPS each month. But, it’s hard to recycle because it’s big and needs special processes.

Key Takeaways

  • Polystyrene, including Expanded Polystyrene (EPS), is a widely used plastic material that is 100% recyclable.
  • Recycling facilities for polystyrene are limited, making proper disposal challenging.
  • In 2020, the United States generated 292 million tons of municipal solid waste, with 146 million tons ending up in landfills, 30% of which was EPS.
  • The United Kingdom recycles over 100 tonnes of EPS monthly, but challenges remain due to its bulky nature and the need for specialised recycling processes.
  • Sustainable alternatives and solutions, such as eco-friendly packaging options and polystyrene compacting technology, are being explored to address the environmental impact of polystyrene waste.

Understanding Polystyrene and Its Types

Polystyrene is a versatile plastic material. It comes in different forms, each with its own properties and uses. Let’s look at the main types of polystyrene and what makes them special.

General Purpose Polystyrene (GPPS)

GPPS is a clear, rigid plastic. It’s great for electrical uses, stands up to radiation, and is not too strong. Its clearness makes it perfect for food packaging and medical tools.

High Impact Polystyrene (HIPS)

HIPS is stronger and more resistant to impact than GPPS. It’s also more rigid, shiny, and easy to paint. This makes it great for car parts and home appliances.

Expanded Polystyrene (EPS)

EPS is a light foam made from polystyrene beads. It’s mostly air, making it a good insulator. It’s used in packaging and building insulation. But, it’s hard to recycle because it’s so light.

Property GPPS HIPS EPS SPS
Density (g/cm³) 1.04-1.09 1.04-1.06 1.05 1.01-1.4
Tensile Strength (MPa) 45 15-30 0.2-0.5 41
Flexural Strength (MPa) 60-100 40-70 0.2-0.5 70-100
Thermal Conductivity (W/(m·K)) 0.04-0.15 0.16 0.03-0.04 0.16
Glass Transition Temperature (°C) 80-105 70-80 80-82 100-120

Polystyrene can be made in many ways, like injection moulding and extrusion moulding. Knowing the special features of each type is key to picking the right one for your needs.

Is Polystyrene Recycling Possible in the UK?

Yes, recycling polystyrene is possible in the UK, but it’s tough. Figures show only 1% of UK councils could recycle polystyrene trays in 2018. Most councils say to throw it away because recycling facilities are scarce.

But, businesses can make up to £500 per tonne by recycling it. The UK government has also banned single-use plastics, including polystyrene, from 1 October 2023. Some uses in the supply chain might be allowed.

Key Polystyrene Recycling Statistics in the UK
Close to four million tonnes of post-consumer plastic waste underwent treatment in the UK through official schemes in 2018.
Out of the total post-consumer plastic waste treated in the UK in 2018, only 32% was recycled.
The Expanded Polystyrene Group reports that over half of all Expanded Polystyrene packaging is recycled in the UK annually.
In Manchester and the North West, one-fifth of the one million bins collected and emptied by Fresh Start Waste each year are designated for recycling plastics.

The UK doesn’t have enough places to recycle polystyrene on a big scale. This makes proper disposal key to protect the environment. Expanded Polystyrene (EPS) is 100% recyclable and mostly air, which makes it a good choice if recycling facilities exist.

“EPS is 100% recyclable, has an Ozone Depletion Potential (ODP) of zero, and can be compacted and turned into super dense bales that can be easily palletized and shipped.”

Creating green packaging solutions, like for polystyrene, is vital. It helps cut down on waste and lessens the harm packaging does to the environment.

Environmental Impact of Polystyrene Waste

Polystyrene, or Styrofoam, can take up to 500 years to break down. This is a big problem for our environment. As it breaks down, it turns into microplastics that harm marine life.

Microplastics Formation

Polystyrene breaks down slowly into tiny microplastics. These small pieces can spread through the air and water. They can pollute soil and water, and even get into our food.

Effects on Marine Life

Marine animals, like fish and seabirds, eat polystyrene thinking it’s food. This can cause them to be malnourished, get blockages, and even die. Every year, 22 million polystyrene fish boxes are used in the UK to transport fish.

Landfill Concerns

Polystyrene waste is a big problem in landfills, making up 30% of waste. It’s light, so it can easily spread pollution in both land and water.

Statistic Value
Polystyrene fish boxes used annually in the UK 22 million
Percentage of litter that is food and food packaging in the UK 23%
Daily oil consumption used for polystyrene production 0.01%
Plastic or polystyrene pieces found per 100 meters of beach in the UK 182.6

The pollution from polystyrene waste is a big worry. It lasts a long time and harms our oceans and landfills. We need to act fast to protect our planet.

Challenges in Polystyrene Recycling

Polystyrene is widely used but recycling it is tough. Its low density and high volume make it expensive to transport and store. This makes recycling polystyrene not very cost-effective.

Also, if polystyrene gets contaminated with food or other stuff, it’s harder to recycle. It needs to be cleaned and prepared well before recycling.

There aren’t many places where you can recycle polystyrene. Most recycling bins at home don’t accept it. This is because recycling it often results in low-quality products, which isn’t worth the cost.

Recycling Obstacle Impact
Low density and high volume Increases transportation and storage costs, hindering economic viability
Contamination with food residues or other materials Complicates the recycling process, requiring thorough cleaning and pretreatment
Lack of widespread recycling facilities Reduces accessibility and availability of recycling options for consumers
Need for specialised equipment Increases the cost and complexity of the recycling process

New ways to recycle polystyrene are being developed. These methods can turn polystyrene back into its basic chemicals. This could make recycling it more appealing and profitable, helping to reduce waste and pollution.
