What You'll Learn
Philadelphia's plastic recycling rate is between 5% and 13%
Philadelphia's plastic recycling rate is estimated to be between 5% and 13%. This range reflects the challenges and complexities of plastic recycling, not just in Philadelphia but also in other cities across the United States. The low recycling rate of plastics is attributed to various factors, including contamination, market conditions, and the low cost of "virgin" plastic.
Contamination is a significant issue in Philadelphia's recycling system. The city's single-stream recycling system, implemented in 2007, allows all recyclable materials to be placed in the same bin without sorting. While this increased participation and efficiency, it also led to a higher rate of contaminated materials. Residents often commingle different types of plastics or include non-recyclable items, such as plastic bags, food waste, and other contaminants, which can render entire loads unrecyclable.
Market conditions also play a role in Philadelphia's low plastic recycling rate. Recycling is influenced by economic factors, and the demand for recycled materials can fluctuate. If there is no market or demand for certain recycled plastics, they may not be recycled at all. Before 2018, most of Philadelphia's recycling was sent to China. However, China banned the importation of plastics in 2019, and other countries, like Vietnam, Thailand, and Malaysia, have also pushed back against accepting American plastics. This has disrupted the recycling market and contributed to the low recycling rate.
Additionally, the low cost of "virgin" plastic, or new plastic, makes recycling plastic less economically viable. It is often cheaper to produce new plastic than to recycle existing plastic, reducing the incentive for companies to utilize recycled materials. This structural issue contributes to the low recycling rate, not just in Philadelphia but across the United States, where only about 5% of plastic waste is recycled, according to a 2022 report.
To address these challenges, Philadelphia's Sanitation Division is working to educate residents about proper recycling practices to reduce contamination rates. The city has also taken steps to reduce the use of single-use plastic bags and encourage the reuse and recycling of materials. However, systemic changes are needed to create a more circular economy and increase plastic recycling rates in Philadelphia and beyond.

Plastic bags are not recyclable
Philadelphia's recycling rate currently sits at 13%, a 5% increase from a few years ago, but still below pre-pandemic levels. The city's recycling system is broken, and there is no guarantee that recyclable materials are actually recycled. The recycling of plastic bags is a complex issue. While plastic bags may display recycling symbols, they are not typically recyclable through curbside collection systems. This is due to their lightweight structure, which can cause tangling in the gears of recycling trucks and sorting equipment at recycling facilities (MRFs). This results in delays, shutdowns, and safety hazards for workers who must manually cut and remove jammed bags.
Plastic bags are made from low-density polyethylene (LDPE), a flexible plastic that is not easily recyclable through traditional curbside methods. They are one of the most labour-intensive items to sort at recycling facilities, as they often require manual removal from the line. When missed, they can cause equipment damage and even plant shutdowns. Additionally, when mixed with other recyclables, plastic bags become contaminated and are no longer acceptable to end-users.
To address this issue, many grocery stores and retailers provide collection bins specifically for plastic bags. These bins ensure proper management and disposal by sending them to facilities equipped to handle plastic bags. Some organisations, like Recycle Ann Arbor, provide drop-off stations for plastic bags, allowing for separate baling and recycling to prevent contamination of other recyclables.
While Philadelphia's sanitation division educates residents about unacceptable items, including plastic bags, greasy pizza boxes, styrofoam, and wet paper, the city's recycling system faces challenges with contamination and market conditions. The city has stopped burning recyclables and mixing trash with recycling, but contaminated recycling loads remain an issue.
To reduce the environmental impact of plastic bags, it is recommended to refuse, reduce, reuse, or repurpose them. Residents can opt for reusable bags, recycle at store drop-off locations, or find creative ways to repurpose plastic bags, such as using them for trash can liners, carriers, or packing material. These actions contribute to minimising plastic pollution and advancing toward a Zero Waste future.

Plastic contamination is a problem
The issue of plastic contamination in Philadelphia is complex. On one hand, the city has implemented a single-stream recycling system, which has increased participation and efficiency by allowing all recyclable materials to be thrown into the same bin without sorting. However, this has also led to an increase in contaminated materials, as residents are confused about what can and cannot be recycled. Plastic bags, for example, are not accepted for municipal pickup as they tear and wrap around the processing machines, causing equipment damage and even safety issues for workers.
Contamination is a critical issue in recycling. The city's sanitation department has stated that the contamination rate needs to be below 0.5% for recycling to be effective. However, when glass is collected with paper, and food packaging contains food waste, it leads to contaminated recycling. Additionally, residents often commingle different types of plastics, such as Nos. 1 and 2 plastics with other types, contaminating loads that sorting facilities cannot bundle for recycling. These contaminated loads end up in landfills or incineration instead of being recycled.
To address plastic contamination, Philadelphia is taking several measures. The city is working to educate residents about proper recycling practices through educational campaigns and community meetings. They have also provided a Recycling Guide that offers information on what is accepted, how to prepare items for recycling, and safe disposal methods. Philadelphia is also reducing the use of single-use plastic bags and encouraging the reuse and recycling of materials like aluminum cans.
However, despite these efforts, plastic contamination remains a challenge. The system needs to evolve to create a more interdependent and mutually beneficial relationship between producers and consumers. This includes developing infrastructure and economically viable markets for the reuse and recycling of materials. With the right approach and collaboration, Philadelphia can make significant strides in reducing plastic contamination and improving its recycling rates.

China banned the importation of plastics in 2018
Philadelphia's current recycling rate is 13%, up from a previous low of 8% but still below pre-pandemic levels and lower than other cities. The city's sanitation department has said that the contamination rate needs to be below 0.5% for recycling to be effective. However, the presence of contaminated materials in the city's recycling stream remains a significant issue.
Philadelphia's recycling system can only truly recycle two types of plastic: Type 1 plastics, like water and beverage bottles, and Type 2 plastics, like milk or detergent jugs. It is estimated that only about 5% of plastics are actually recycled due to structural degradation and the low cost of "virgin" plastic.
In 2018, China implemented a ban on the importation of most plastic waste, a policy known as "'National Sword.'" This move had a significant impact on global plastic waste trade flows, as China had been the largest importer of plastic waste for decades, accounting for 45% of the world's plastic waste imports since 1992.
The ban was enacted to address the issue of contaminated and soiled materials overwhelming Chinese processing facilities, which was causing environmental problems in the country. As a result, China's plastic imports plummeted by 99% in the year following the ban, leading to a major shift in how and where recycled materials are processed.
The ban has had far-reaching consequences, with as much as 111 million tons of plastic waste requiring alternative processing or disposal solutions. While some lower-income countries, primarily in Southeast Asia, attempted to take up the slack, many lacked the infrastructure to handle the volume of recyclables, leading to further import cutbacks.
The ban has highlighted the need for systemic change and the development of better solutions to manage the growing problem of plastic waste globally.

Plastic recycling is an economic system
Philadelphia's recycling system is broken. The city's current recycling rate is 13%, up from a low of 8% a few years ago, but still below pre-pandemic levels and lagging behind other cities. The implementation of a single-stream recycling system in 2007 increased participation and efficiency, but it also led to a higher amount of contaminated materials in the city's recycling stream. The contamination rate needs to be below 0.5% for recycling to be effective.
The problem is that recycling is an economic system. Recycled materials are commodities, and their prices fluctuate due to market conditions and supply and demand. If there is a market for recycled materials, they get recycled; if not, they are scrapped. This is why only about 5% of plastic waste in the US gets recycled, despite the efforts of cities like Philadelphia to encourage recycling. The low recycling rate of plastics is also due to the complexity of the process, the degradation of the material, and the low cost of "virgin" plastic.
Philadelphia residents have expressed confusion about what can and cannot be recycled, and this uncertainty may cause them to give up on recycling altogether. Plastic bags, for instance, are not recyclable curbside as they tear and wrap around the moving parts in recycling processing machines, leading to higher maintenance costs, equipment damage, and worker safety issues. Other non-recyclable plastics include Styrofoam, yogurt containers, and flexible plastic packaging.
To improve Philadelphia's recycling system, the city needs to educate residents about proper recycling practices and provide clear guidelines on what can and cannot be recycled. Additionally, the city should invest in infrastructure and economically viable markets for the reuse and recycling of materials. By shifting some of the money spent on trash and recycling towards businesses operating with circular principles, Philadelphia can create a more sustainable and efficient recycling system.
In conclusion, plastic recycling in Philadelphia is part of an economic system that is influenced by market demands, supply and demand, and the cost of recycling processes. By addressing the challenges of contamination, infrastructure, and economic viability, Philadelphia can work towards improving its recycling rates and creating a more sustainable future.
