Plastic waste is a major environmental issue, with the UK producing a substantial amount. While recycling is one way to tackle this problem, it is not enough. The UK's recycling rate for plastic is estimated to be between 12% and 17%. However, due to varying measurement methods, it is challenging to compare global recycling levels accurately. The UK's plastic waste management is largely dependent on exports, with a significant portion being incinerated or sent to landfills. The complex nature of plastic recycling, the degradation of recycled plastics, and the lack of infrastructure further contribute to the low recycling rates.

What You'll Learn
The UK's plastic waste problem
In 2023, the UK's plastic packaging recycling rate stood at 52.5%, the highest figure recorded in over a decade. However, this rate includes energy recovery from incineration and plastic waste exports, which account for a significant portion of the UK's waste management. It is believed that almost half of all UK plastic waste is incinerated for energy recovery, and only about 12% to 17% is recycled domestically in UK reprocessing facilities. The remaining waste is exported to other countries, with Turkey being the leading destination in 2023.
The low recycling rate in the UK is due to various factors. Firstly, the country lacks the infrastructure to deal with the large volume of plastic waste it produces. This has led to a reliance on waste exports to other countries for many years. However, recent bans and restrictions on waste imports by countries such as China have placed increased pressure on the UK to improve its waste management systems.
Another challenge is the complex nature of the recycling process itself. Most plastics can only be recycled one or two times before degrading, limiting the practical benefits of plastic recycling. The first step of waste plastic separation is costly and time-consuming, and composite plastics made of multiple materials cannot always be separated for recycling. Additionally, the recycling process is not always environmentally friendly, as some recycling plants produce microplastics even with filtration systems in place.
To address the plastic waste problem, the UK government has introduced policies such as the single-use carrier bag charge, which has successfully reduced the number of single-use plastic bags issued by supermarkets. However, more comprehensive changes are needed at the policy level, and brands must also play a more significant part in reducing plastic waste. Consumers can also make a difference by reducing, refusing, reusing, and recycling plastic whenever possible.

Plastic recycling rates in other countries
The UK's plastic recycling rate is estimated to be between 12% and 17%. However, it is challenging to compare recycling rates across countries due to variations in measurement methods. Some countries measure recycling rates per capita, while others use weight or specific types of plastic.
Now, let's look at plastic recycling rates in other countries:
United States
The United States is not among the top 10 recycling countries globally. The plastic recycling rate was 8.7% in 2018, according to the Environmental Protection Agency (EPA). An NGO report claimed that this rate dropped to around 5% in 2021. The critical issue in the US is the sorting and management of discarded plastic. The lack of standardised labels on recycling bins adds to the challenge. However, US C&D recyclers are actively working to increase recycling within this waste stream.
Germany
Germany is recognised as the world leader in recycling. It has a comprehensive sorting system for different materials, including glass bins for bottles and jars, which are further sorted by colour. Germany's recycling resources, such as properly labelled bins and accessible pick-up locations, are well-established and advertised, making it easier for people to recycle correctly.
Republic of Ireland
The Republic of Ireland is one of the top plastic recyclers in the EU, with an annual per capita recycling rate of 20.70 kg of plastic waste.
Austria
Austria has consistently been a leader in recycling until the last three years. It has implemented C&D waste management initiatives at the state and local levels, with the city of Vienna taking the lead in reducing C&D waste.
China
China has recently imposed bans and restrictions on waste imports, including plastic waste, which has put pressure on other countries, like the UK, to improve their waste management systems.

Why recycling levels are so low
The UK recycles only 17% of its annual plastic waste. This is a staggeringly low figure, especially when compared to other EU countries like the Republic of Ireland (20.70 kg of plastic waste per capita each year) and Germany (19.98 kg per capita annually).
There are several reasons why plastic recycling levels are so low in the UK:
Lack of Infrastructure
The UK lacks the infrastructure to deal with the enormous amounts of plastic waste it produces each year. This has led to the UK relying on exports to other countries for many years. However, recent bans and restrictions on waste imports by countries like China have placed increased pressure on the UK to manage its waste more effectively. The UK government has been urged to invest in recycling infrastructure and new recycling technologies.
Complexity and Cost of Recycling
Plastic recycling is a complex and costly process. Different types of plastics, such as polyvinyl chloride (PVC), polypropylene (PP), and polyethylene (PE), cannot be recycled together and must be separated, which is a time-consuming and expensive task. The recycling process also involves multiple steps, including collection, sorting, processing, and transportation, which add to the overall cost. As a result, in many cases, throwing plastic away is still easier and more cost-effective for brands than recycling it.
Low Quality of Recycled Plastic
The quality of recycled plastic is reduced due to the recycling process, which alters the molecular structure of the plastic. This limits the number of times plastic can be recycled before it degrades, reducing the practical benefits of plastic recycling.
Inadequate Government Action
While the UK government has introduced various policies to reduce plastic waste, such as the single-use carrier bag charge, these initiatives have had minimal impact. The government has been criticized for not taking more urgent and effective action to address the plastic waste crisis.
Public Awareness and Education
Public awareness and education about plastic recycling may also play a role in the low recycling levels. Some people may not understand the importance of recycling or how to properly recycle plastic waste. Additionally, the variety of recycling labels on plastic packaging in the UK, with 28 different labels, can be confusing for consumers.

The plastic recycling process
The second stage is sorting plastic from other materials, which can be done manually or using advanced sorting machines with infrared, x-ray, or other sensors. This stage may involve multiple rounds of sorting to separate the different types of plastic and ensure any remaining contamination is removed.
Once the plastic has been sorted, it is washed to remove food or other materials. This can be done using friction washers, which are the most common form due to their low operation cost and effectiveness, or rotary washers, which use a heated caustic solution to remove oils and food stuff.
After washing, the plastic is shredded or ground into smaller flakes or particles. This is followed by melting, where the plastic is forced through an extruder and cut into pellets, which are then sold to manufacturers.
It is important to note that the plastic recycling process is complex and expensive, and most plastic can only be recycled one or two times before degrading. In addition, the UK lacks the infrastructure to deal with the large amounts of plastic waste it produces, so it has relied on exports to other countries for many years. As a result, the UK's plastic recycling rate is estimated to be between 12% and 17%.

How to improve the UK's recycling rate
The UK's plastic recycling rate has stagnated in the past five years, hovering around 44% in 2021. However, there are several ways to improve this rate and reduce plastic waste.
Firstly, the UK government should invest in recycling infrastructure and new technologies. The country currently lacks the capacity to manage its vast plastic waste production and has relied on exporting waste to other countries. However, recent restrictions on waste imports by nations like China have highlighted the urgency of improving domestic recycling capabilities. The government has introduced policies such as the single-use carrier bag charge, which has successfully reduced plastic bag usage in supermarkets. Additionally, the UK has committed to international initiatives to tackle ocean plastics and plans to make all plastic packaging recyclable, reusable, or compostable by 2025.
Secondly, standardising and simplifying recycling practices can enhance participation and effectiveness. Currently, recycling levels are impacted by inconsistent collection methods across local authorities, with some materials being collected in certain areas but not in others. Standardising and simplifying recycling collections across England can ensure a consistent set of materials is collected, making it clearer and more convenient for residents to recycle.
Thirdly, addressing the complex nature of plastic recycling is crucial. Most plastics are theoretically recyclable, but only a small percentage is actually recycled due to the challenges of sorting, collecting, processing, and transporting waste plastic. Improving recycling rates requires addressing these logistical hurdles and making the process more economically viable. This may involve incentivising packaging producers to take financial responsibility for the end recycling of their products through an extended producer responsibility (EPR) scheme.
Furthermore, consumer and brand efforts are essential. Consumers can reduce plastic waste by reusing and recycling plastic products whenever possible. Brands, on the other hand, can support the environment by partnering with organisations that promote sustainable practices, such as CleanHub, and by embracing recycled materials for their packaging.
Lastly, education plays a vital role in improving recycling rates. Raising awareness about the importance of recycling, as well as providing clear instructions on how to recycle different types of plastics, can empower individuals to make more environmentally friendly choices.
