The Plastic Recycling Myth: What's Really Recyclable?

Plastic is everywhere, from detergent bottles to ketchup containers. But what happens when we throw it away? Is it all recyclable? The short answer is no. While most plastics are theoretically recyclable, only a small percentage is actually recycled due to the complex nature of the process. The recycling rate for plastic stands at 8.7%, according to the Environmental Protection Agency's 2018 data. However, this figure varies depending on the industry and type of plastic, and it's important to note that not all plastic can be recycled. The low recycling rate for plastic contributes to pollution, with plastic ending up in landfills, oceans, and even our bodies, as studies showing plastic particles in breast milk, placenta, and blood indicate. So, what can we do to address this issue? Some advocate for legal reform to hold the plastic industry accountable for its negative impact on the environment, while others suggest reducing plastic consumption by seeking out stores that offer product refills in reusable containers.

Plastic recycling rates vary worldwide

In the United States, the world's biggest plastic polluter, only around 5% of plastic waste was recycled in 2021. This is despite the fact that the amount of plastic sent for recycling has doubled since 2006, and the amount of plastic going to landfill has decreased by 44%. However, the majority of plastic packaging collected in the UK is exported for recycling due to insufficient domestic capacity.

The recycling of post-consumer plastic in the UK has increased by 140% since 2006, and the amount of plastic sent to landfill has been reduced by two-thirds. The average amount of plastic packaging recycled within the EU is 42%, with the UK recovering 86% of its plastic packaging (through recycling or energy generation).

While some materials like glass and aluminum have high recycling rates and can be recycled endlessly, plastic cannot be repeatedly recycled without degrading in quality. This is why plastic is often seen as a contributor to pollution, as it ends up in landfills, water sources, and even human bodies.

To improve plastic recycling rates, widespread legal reform and international cooperation are needed to reduce plastic production and improve waste management. This includes developing environmentally friendly alternatives, improving recycling technologies, and creating a separate market for recycled plastics to make secondary markets more competitive and profitable.

Plastic recycling is not economically viable

Plastic recycling is not currently economically viable due to a variety of factors, including the high costs of separating and sorting plastics, the low value of recycled plastic compared to virgin plastic, and the lack of infrastructure to support large-scale plastic recycling.

Firstly, the cost of separating and sorting plastics is a significant barrier to economic viability. Different types of plastics have different recycling requirements and cannot be recycled together, making the process costly and complex. This is further compounded by the fact that most plastic packaging is produced from multiple grades of plastic that are incompatible with each other. As a result, the cost of sorting and separating plastics can outweigh the benefits of recycling them.

Secondly, the low value of recycled plastic compared to virgin plastic is a critical issue. Virgin plastic, or new plastic made from oil or gas, is often cheaper to produce than recycled plastic. This is because the cost of using oil or gas to make new plastic is very low, and the process is less complex than recycling plastic waste. As a result, the market for recycled plastics is limited, and the demand for raw recycled plastic has slowed.

Additionally, the lack of infrastructure to support large-scale plastic recycling contributes to the economic inviability of plastic recycling. While there have been some technological advances in recycling processes, the infrastructure to support these technologies on a large scale is often lacking. This includes insufficient capacity to recycle plastic within certain countries, leading to the export of plastic waste to other countries for recycling.

The economic inviability of plastic recycling is further evidenced by the failure of numerous projects publicized by the oil and gas industry. These projects, which aimed to recycle plastic on a large scale, ultimately shuttered or failed due to the economic challenges of plastic recycling.

Furthermore, the plastic industry's awareness of the limitations of recycling has contributed to the issue. Despite knowing that recycling would not keep plastic out of landfills and the environment, the industry spent millions promoting recycling to sell more plastic. This misled consumers into believing that plastic was recyclable on a large scale, when in reality, only a small fraction of plastic is truly recyclable.

In conclusion, plastic recycling is not currently economically viable due to the high costs of separating and sorting plastics, the limited market for recycled plastics, and the lack of infrastructure to support large-scale recycling. While there may be potential for economically viable ways to reuse plastic in the future, the current system is not designed to handle the volume of waste plastic generated.

Plastic recycling is not environmentally viable

The plastic industry has been accused of deceiving the public by claiming that plastics are recyclable when over 90% of them are not. This has resulted in consumers believing that recycling is a solution to the plastic pollution crisis, which is not the case. Recycling plastic can even be more toxic and harmful to human, animal, and environmental health. Research by Greenpeace has shown that recycled plastics often contain higher levels of toxic chemicals, such as flame retardants, benzene, and other carcinogens.

Furthermore, the recycling process itself releases significant microplastics and harmful chemicals into the environment. About 13% of plastics infiltrate water or air as microplastics from recycling facilities in the UK. Recycling plastic also involves size reduction and washing, which contribute to the scattering of microplastic pollution. The limited market for recycled plastics further diminishes the viability of plastic recycling. New virgin plastic is often cheaper than recycled material, and the demand for raw recycled plastic is slowing due to factors such as rising transport costs and the slowdown in the construction sector.

While recycling rates for plastic bottles in certain states have been successful due to legislation banning single-use plastics and "bottle bills," the overall recycling rate for plastics is low. The complexity and incompatibility of different types of plastics further hinder the recycling process, as they cannot be recycled together and are costly to sort. As a result, the majority of plastic ends up in landfills or the environment, contributing to pollution and damaging ecosystems. Therefore, it is clear that plastic recycling is not a sustainable solution, and the focus should be on reducing plastic consumption and production.

Plastic recycling is not always possible

Firstly, the recycling process for plastic is intricate and challenging. Plastic must be separated into different polymers such as polyvinyl chloride (PVC), polypropylene (PP), and polyethylene (PE) before recycling as they cannot be recycled together. This sorting process is labor-intensive and costly, and even after separation, the quality of the recycled plastic is reduced with each recycling cycle due to changes in its molecular structure.

Secondly, the economic viability of plastic recycling is questionable. The low cost of raw materials and the affordable price of new plastic make it more cost-effective for brands to dispose of plastic waste rather than recycle it. In the US, for example, disposing of waste in a landfill costs around $60 per ton, while sorting and recycling one ton of curbside recycling can cost up to $120. Additionally, the market demand for recycled plastic is limited, further reducing the incentive for recycling.

Thirdly, infrastructure and standardization play a crucial role in plastic recycling. Recycling programs vary across different regions, and some areas lack the necessary infrastructure for effective plastic recycling. For instance, recycling programs for furniture and appliances are lacking in many places, and the absence of standardized systems leads to inconsistencies in recycling rates and methods.

Furthermore, education and awareness about plastic recycling are essential. Consumers often assume that plastic products are recyclable due to misleading resin identification codes and symbols on packaging. However, in reality, certain types of plastic cannot be recycled, and improper recycling can lead to contamination and negative environmental impacts.

Lastly, the plastic industry's greenwashing practices contribute to the challenges of plastic recycling. Oil companies and plastic manufacturers have been accused of overstating the recyclable properties of their products, leading to confusion and mistrust among consumers. Additionally, the industry's focus on promoting recycling as a solution to plastic pollution has been criticized as an attempt to justify continued plastic use rather than transitioning to genuinely recyclable materials.

Plastic recycling is not always properly done

Additionally, the plastic industry has been accused of misleading the public by claiming that plastics are recyclable when, in reality, over 90% of plastics are not. This has led to consumers being overwhelmed by the amount of plastic they believe can be recycled, when in fact, it ends up in landfills, water sources, and the environment. For example, in the United States, which is the world's biggest plastic polluter, only around 5% of plastic waste was recycled in 2021, with the rest ending up in landfills and the ocean.

Furthermore, there is a lack of education and awareness about proper recycling practices. Many people are unaware of what, where, and how to recycle properly, and there is a blind trust that recycling companies are handling the rest. This has led to contamination in mixed container recycling bins, further reducing the amount of plastic that can be recycled.

While some countries, like the UK, have seen an increase in plastic recycling rates, the process is not without its challenges. For instance, 61% of the plastic packaging collected in the UK is exported for recycling due to insufficient capacity to recycle it domestically. This highlights the need for better infrastructure and sustainable business plans for the plastic recycling industry.

Overall, plastic recycling is a complex issue that requires a multifaceted approach. It involves addressing the overconsumption of single-use plastics, improving recycling technologies, implementing effective policies, and educating the public about proper recycling practices. By tackling these issues, we can work towards ensuring that plastic recycling is done properly and reducing the environmental impact of plastic waste.
