Plastic Recycling: Pollution Paradox?

Plastic recycling has long been touted as a solution to the ever-growing problem of plastic pollution. However, evidence suggests that recycling plastic may not be as effective as previously thought and could even be making the problem worse. Research has found that the process of recycling plastic can release harmful microplastics and toxic chemicals into the environment, threatening the health of both workers in the industry and those living nearby. With less than 9% of all plastic ever made having been recycled, it is clear that plastic recycling alone cannot solve the plastic pollution crisis. Instead, a drastic reduction in plastic production and a focus on plastic-free reuse are necessary to address this pressing issue.

Recycling plants may create microplastics

Despite the well-intentioned push for recycling plastic, plastic pollution and its toxic impacts continue to grow. A recent peer-reviewed study that focused on a recycling facility in the United Kingdom suggests that anywhere between 6 to 13% of the plastic processed could end up being released into water or the air as microplastics. These microplastics are tiny particles smaller than five millimeters that have been found everywhere, from Antarctic snow to inside human bodies.

Research out of Scotland suggests that the chopping, shredding, and washing of plastic in recycling facilities may turn as much as 6 to 13% of incoming waste into microplastics. If the team's calculations are found to be representative of the recycling industry as a whole, the scale of microplastics created during recycling processes would be shocking—perhaps as much as 400,000 tons per year in the United States alone, or the equivalent of about 29,000 dump trucks of microplastics.

The study suggests that recycling could be exacerbating the problem of plastic pollution by creating an even more vexing conundrum. Unlike other ways microplastics can enter the environment, recycling facilities could be identifiable sources. "We know where the pollution is coming from... and we could take measures to actually do something about it through permitting, through regulation, through all of those kinds of rules we have available," said Anja Brandon, associate director of U.S. plastics policy at Ocean Conservancy.

However, it is important to note that the answer is not to stop recycling plastic. "What this study does not tell us... is that we should stop recycling plastic," Brandon said. "So long as we are continuing to use plastic, mechanical recycling is really the best end-of-life scenario for these materials to keep us from needing to produce more and more plastic." Instead, the focus should be on reducing plastic consumption and improving recycling processes to minimize the creation of microplastics.

Recycling processes are inefficient and unsustainable

Recycling processes are often inefficient and unsustainable. Firstly, the recycling process itself can be harmful to the environment. For example, the process of recycling paper requires the use of chemicals and large amounts of water and energy. Similarly, recycling plastic can release harmful pollutants into the air and water. Research from Scotland suggests that the chopping, shredding, and washing of plastic in recycling facilities may turn as much as 6 to 13% of the waste into microplastics, which are toxic particles that contribute to environmental and human health issues.

Secondly, recycling is often expensive to implement and maintain due to the need for specialized equipment and infrastructure. The value of recycled materials is also frequently lower than the cost of producing new materials, making it difficult for recycling programs to be financially sustainable. This is especially true when considering the contamination of recycling batches with non-recyclable materials, which can render the entire batch unusable.

Thirdly, recycling may perpetuate a culture of consumption and disposal, as people may feel less conscious about their consumption and waste generation when they believe that recycling will neutralize their behavior's impact. This mentality may be reinforced by the recycling symbol, which was created by plastic manufacturers to mislead people into thinking that all plastic was recyclable.

Finally, recycling rates for plastic are extremely low, with only about 9% of plastic waste ever being recycled. Much of this recycled plastic undergoes downcycling, where it is made into items of lesser value and quality, continuing to cause pollution. Therefore, recycling must be coupled with a drastic reduction in plastic production to be more beneficial than harmful.

Recycling is not a solution to plastic pollution

Despite the push for recycling plastic, plastic pollution and its toxic impacts continue to grow. Recycling is not a solution to plastic pollution because it is not a cure-all for the planet's enormous plastic problem. The real problem is the uncontrolled rise of plastic production, which has increased by more than 18,300% in the last 65 years. Less than 9% of all plastic ever made has been recycled, and recycling processes continue to drive plastic pollution through the creation of microplastics, chemical pollution, and more.

Recycling plastic is not a solution to plastic pollution because it is just one part of a complex problem. Plastic recycling infrastructure and activities can cause polluted air, soil, and drinking water. Communities near plastic recycling sorting centers often face increased health risks and poor working conditions. Additionally, the process of recycling plastic requires large amounts of energy, emitting chemicals and greenhouse gases, wasting water, and creating microplastics and nanoplastics.

Furthermore, recycling is often pitched as an advanced or chemical solution, but it is mostly "downcycling," turning plastic into items of lesser value and quality, such as turning plastic water bottles into fleece jackets or carpet fiber. These continue to cause considerable pollution. The focus on recycling also distracts from real solutions, such as turning off the plastic tap and promoting plastic-free reuse.

The blame for the plastic problem is often placed on wasteful consumers, but the real issue is the massive production of single-use plastic. Encouraging individuals to recycle more will never solve the problem of the massive production of plastic that should have been avoided in the first place. Plastic producers have a responsibility to reduce plastic production and support reuse solutions that end wastefulness at the source.

Therefore, while recycling can be a part of the solution, it is not enough on its own. To address plastic pollution effectively, a combination of reduced plastic production, improved recycling processes, and a shift towards reusable items is necessary.

Plastic recycling harms human rights and the environment

The refining and manufacturing processes of plastic production emit harmful pollutants into the air and water, impacting communities near refineries, which are often low-income and marginalized. Plastic products contain toxic chemical additives, and the ingestion of plastic particles has been linked to impacts on cell function, chronic inflammation, and endocrine system disruptions. The release of microplastics during the recycling process further contributes to environmental contamination.

The lifecycle of plastics, from extraction to disposal, negatively affects people and the environment. Single-use plastics, which account for half of all plastic produced, prioritize convenience over durability, contributing to the throw-away culture. The extraction and creation of single-use plastics emit vast amounts of greenhouse gases, contributing to climate change.

The low global recycling rate of only 9% and the focus on recycling as a solution to plastic waste have been ineffective in curbing the impact of rising plastic production. Recycling alone cannot address the plastic pollution crisis, and it often leads to "downcycling," where recycled plastics are made into items of lesser value, continuing to cause pollution. Misinformation campaigns by the plastic industry have hidden the true cost of plastics, infringing on the right to information.

To address the negative impacts of plastic on human rights and the environment, a comprehensive approach is necessary. This includes reducing plastic production, prioritizing plastic-free reuse, and integrating a human rights-based perspective into plastics policy. The international community must take transformative steps to reverse the plastics crisis and safeguard human rights for present and future generations.

Plastic recycling facilities are often located in low-income communities

Despite the narrative that recycling is an effective solution to plastic pollution, it is, in fact, a false solution. Recycling plastic does not address the root of the problem, which is the overproduction of plastic. Less than 9% of all plastic ever made has been recycled, and recycling processes continue to drive plastic pollution and its toxic impacts.

In addition, plastic recycling facilities are often located in low-income communities. This is due to racial discrimination in zoning and the housing market, as well as siting decisions based on following the path of least resistance. Low-income communities are targeted because they have fewer resources and political clout to oppose the siting of unwanted facilities. Hazardous waste sites, polluting industrial facilities, and other locally unwanted land uses are disproportionately located in non-white and poor communities.

The establishment of these facilities in low-income communities has serious health implications for the residents. Plastic recycling infrastructure and activities can cause polluted air, soil, and drinking water. The constant traffic from trucks, trains, or barges, as well as the presence of scavenger animals attracted to eating waste, further contribute to the negative impact on these communities.

Furthermore, the process of breaking down plastics during recycling can generate polluting microplastics that end up in the water or air. A recent study found that between 6 to 13% of the plastic processed in a recycling facility could be released as microplastics. These microplastics have been found everywhere, from Antarctic snow to inside human bodies, and have been associated with serious health impacts, including changes to genetics, brain development, and reproduction.

While recycling may not be a comprehensive solution to plastic pollution, it is important to note that the answer is not to stop recycling altogether. Mechanical recycling is still the best end-of-life scenario for plastic materials, as it helps reduce the need to produce more plastic. However, recycling must be coupled with a drastic reduction in plastic production to effectively address the plastic pollution crisis.
