Recycling is a topic that has been at the forefront of many people's minds in recent years, with an increasing number of individuals aspiring to produce zero waste. However, the process of recycling, particularly when it comes to plastic, has been called into question. While recycling can help reduce waste and conserve resources, there are also cons to the process that are often overlooked. For instance, the carbon emissions and pollution associated with transporting recyclables and the toxic waste generated from breaking down these materials can have negative environmental impacts. In addition, the contamination of recycling streams with non-recyclable materials, such as soft plastic bags, can clog machines and slow down operations. With China and other countries no longer accepting foreign recyclables, the recycling industry is facing new challenges, leading some to question whether recycling plastic is worth the effort.

Plastic bags clog machines and slow recycling operations
While recycling is generally considered a positive activity, there are some items that can cause issues in the recycling process. One of the most common offenders is plastic bags. Soft plastic bags can clog machines and slow down operations, requiring workers to manually remove the bags by hand. This issue is prevalent in facilities like Waste Management's recycling center in Chicago, which is meant to sort cans, bottles, paper, and cardboard, but often receives plastic bags that it is not equipped to handle.
The problem is exacerbated by the increasing use of plastic bags and consumer confusion about what is recyclable. Well-intentioned companies that include the recycling logo on their packaging contribute to this confusion, leading consumers to assume that all plastic bags are recyclable. As a result, plastic bags end up in recycling bins and cause issues for sorting facilities.
Plastic bags can get caught in the rotating rubber "stars" that help move materials through the system, eventually halting the system entirely. This downtime limits the capacity of sorting facilities and drives up costs for recyclers. In some cases, the buildup of plastic bags and other contaminants can cause the machine to stop working altogether, requiring a complete shutdown of operations.
To address this issue, it is important for consumers to understand that plastic bags should not be placed in curbside recycling bins. Instead, they should be returned to retailers or specific charities that collect them for proper bag-specific recycling. By taking plastic bags out of the recycling stream, consumers can help reduce the contamination of recyclable materials and improve the efficiency of sorting operations.

The carbon footprint of transporting recyclables is high
Transport accounts for around one-quarter of global carbon dioxide (CO2) emissions. The carbon footprint of transporting recyclables is, therefore, high, especially when the recyclables are transported long distances or internationally.
MIT researcher Andrew McAfee, for instance, points out that before China banned the import of American recyclables, the US was "packing up all of our plastics, sending it across the ocean, to a country that engaged in environmentally very, very dirty practices, to try to recycle them".
The carbon footprint of transportation is determined by the mode of transport, the distance travelled, and the electricity mix of the country. In general, the most carbon-efficient modes of transport are walking and cycling for short distances, trains for medium distances, and electric vehicles for long distances.
The carbon footprint of transporting recyclables can be reduced by choosing more carbon-efficient modes of transport, reducing the distance travelled by recyclables, and transitioning to cleaner sources of electricity.
However, it is important to note that the carbon footprint of recycling is not limited to transportation. Recycling also emits GHGs during the extraction of raw materials, processing, manufacturing, and distribution.

The US lacks the infrastructure to recycle its own waste
The US has long relied on China to process its recycling waste. In 2013, China began warning US recyclers that it would address its own environmental problems and limit contamination of recycling imports. However, few believed that China would follow through on this threat. As a result, when China enforced stricter limits on the waste it would accept in 2018, US recyclers were unprepared. This left the US with no other option but to pay more to recycle or simply discard the waste.
The US has failed to invest in its own recycling infrastructure, instead relying on China to process its waste. This has resulted in a lack of economic efficiency and efficacy in the US's domestic recycling infrastructure. The US does not have a federal recycling program, and as a result, 20,000 communities in the US make their own choices about whether and what to recycle. This has led to a lack of standardization across the country, with some communities cutting back on their recycling programs or increasing costs to residents.
The US needs to invest in its own recycling infrastructure and create a federal recycling program to ensure that all communities have access to recycling services. Without dedicated investment, the US will continue to lack the infrastructure to recycle its own waste, and recycling will not be seen as a worthwhile endeavor compared to landfilling.
In addition to a lack of infrastructure, the US also faces challenges due to the changing packaging used by consumer brands, which is often done with little regard for whether it can be recycled. The Association of Plastic Recyclers has called on manufacturers to ensure that new packages and containers can be recycled, but a lack of progress has led to legislative proposals in several states. It is important for manufacturers to be held responsible for the waste they create and to encourage the use of low-impact and highly recyclable packaging.

Recycling contamination is a growing problem
Recycling contamination is a significant and growing problem. It occurs when non-recyclable items are placed in recycling bins, or when recyclables are not properly separated, and it can have negative consequences for the environment, businesses, governments, and individuals.
Contamination can occur when people engage in wishful or "aspirational" recycling, tossing items into the recycling bin in the hope that they can be recycled, even if they are unsure. This can include items such as plastic bags, pizza boxes with food stains or grease, and shiny, metallic wrapping paper. While the intention behind wishful recycling may be positive, it can ultimately do more harm than good.
The issue of contamination has been exacerbated by China's decision to stop accepting American recyclables. China previously imported a large portion of the world's recycling waste, but in recent years, it has set stricter limits on what it will accept to reduce "yang laji," or foreign trash. This has left countries like the United States struggling to process their own waste, as they lack the necessary infrastructure. As a result, recyclable materials may end up in landfills, be incinerated, or be exported to other countries, contributing to pollution and environmental harm.
Contamination can also slow down the recycling process and increase operating costs. It can damage recycling machinery and pose safety hazards for workers. For example, plastic bags can clog machines and slow down operations, requiring workers to remove them by hand. Additionally, hazardous waste can cause fires and endanger those working in recycling facilities.
To address the problem of recycling contamination, education is key. It is important for individuals to familiarize themselves with proper recycling practices and to understand that just because an item has a recycling symbol on it does not mean it belongs in the recycling bin. By reducing contamination, we can improve the efficiency of the recycling process and minimize negative environmental impacts.

The market for recyclables is dysfunctional
The recycling industry has been described as being "in crisis", with China's decision to stop accepting foreign recycling waste serving as a significant blow. China's ban on "yang laji" or foreign trash has resulted in recyclables piling up in US ports and warehouses. This has led to increased trash-collection fees and the curtailment of recycling programs in some cities.
The issue of recycling contamination further exacerbates the problem. Despite earnest public information campaigns, many people continue to contaminate recycling bins with non-recyclable items, such as plastic bags, pizza boxes, and gift wrap. This contamination slows down operations and requires manual labor to remove the offending items.
The dysfunctional market for recyclables has also been attributed to the lack of demand for recycled materials. With China and other countries no longer accepting foreign recycling waste, there is a surplus of materials with little to no market value. This has resulted in some localities in America stopping the collection of certain materials and even sending recyclables to landfills or incinerators.
The bottom line is that the worldwide recycling market is in disarray, and it is up to us to find better solutions to the ever-growing plastic problem.

Frequently asked questions
There are arguments for and against the recycling of plastic. On the one hand, the process of recycling plastic produces carbon emissions and pollution from the transportation of materials, as well as toxic waste from breaking down the plastic. It is also expensive to employ people to clean and sort the plastic. However, on the other hand, some people argue that it is better to recycle plastic than to send it straight to landfill.
Recycling plastic creates carbon emissions and pollution from the transportation of materials, as well as toxic waste from breaking down the plastic. It is also expensive to employ people to clean and sort the plastic.
Recycling plastic can prevent it from ending up in landfills in poor countries or in the ocean. It is also better to recycle plastic than to send it straight to landfill.
Instead of recycling plastic, people could lobby for carbon dividends that would drive money from heavily polluting companies back into tax revenue. People could also focus on buying less plastic and using reusable alternatives, such as tote bags instead of plastic bags.
