Paper cups are often lined or coated with plastic to prevent liquids from leaking out or soaking through the paper. This plastic lining, typically made from polyethylene, can make up as little as 5% of the cup. However, it presents a significant challenge to the recyclability of paper cups as most recycling facilities lack the equipment to filter it out. The presence of plastic coatings also means that paper cups cannot be composted as they would contaminate the finished compost with microplastics and potentially toxic chemicals. These microplastics have been linked to health issues such as reproductive harm and an increased risk of cancer. As a result, there is a growing demand for eco-friendly alternatives to traditional plastic-lined paper cups.

What You'll Learn
Paper cups are often lined with plastic
The presence of plastic in paper cups has significant environmental implications. While paper itself is biodegradable, the plastic lining can slow down its degradation process and create issues in composting. Even when composted, the plastic contaminates the finished compost with microplastics and potentially toxic chemicals. Furthermore, the recycling process for paper cups is complex due to the challenge of separating the polyethylene lining. As a result, paper cups often cannot be recycled along with other paper products, contributing to solid waste generation.
The health concerns associated with plastic-lined paper cups are also noteworthy. Studies have found that plastic films, including polypropylene, release microplastics that can be hazardous to human health. These microplastics have been linked to potential health issues such as reproductive harm, metabolic disturbances, and an increased risk of cancer. The release of microplastics occurs within just 15 minutes of the plastic lining coming into contact with a hot beverage. This raises concerns about the potential ingestion of a large number of microplastic particles by individuals consuming multiple hot drinks per day.
To address these environmental and health issues, several alternatives to plastic-lined paper cups are being explored. One option is to use biodegradable bio-plastic coatings like polylactic acid (PLA). PLA-lined cups are fully compostable in industrial composting facilities and do not leave behind any toxic residues. Another approach is the development of recyclable and compostable cups, such as the collaboration between Starbucks and Closed Loop. Additionally, reusable cup programs, like the Freiburg Cup in Germany, aim to reduce the number of single-use cups consumed. These initiatives and innovations are crucial steps towards creating more sustainable alternatives to plastic-lined paper cups.

Plastic-coated paper cups cannot be recycled
The plastic lining in paper cups starts to degrade quickly, with studies showing that it releases microplastics within just 15 minutes of coming into contact with a hot beverage. These microplastics have been linked to potential health issues, including reproductive harm and an increased risk of cancer. Furthermore, the presence of plastic coatings means that paper cups cannot be composted, as they would contaminate the finished compost with microplastics and potentially toxic chemicals.
While some communities have implemented innovative solutions, such as the Freiburg Cup in Freiburg, Germany, a hard-plastic reusable cup, or developed recyclable and compostable alternatives, the majority of paper cups continue to be non-recyclable. This is due to the challenges in separating the polyethylene lining during the recycling process and the lack of infrastructure in most municipalities to accommodate these specialized recycling requirements.
To address the environmental impact of plastic-coated paper cups, individuals can explore alternatives such as purchasing reusable cups or opting for eco-friendly, compostable options certified by organizations like BPI. Additionally, reducing the consumption of single-use paper cups and advocating for improved recycling infrastructure can collectively contribute to a more sustainable future.
Although paper may seem like a more environmentally friendly option, the presence of plastic coatings in paper cups significantly hinders their recyclability. It is important for consumers to be aware of the limitations and potential consequences of using plastic-coated paper cups, as well as the availability of sustainable alternatives, to make informed choices that minimize their environmental footprint.

Plastic lining releases microplastics
Plastic lining in paper cups releases microplastics. A study published in the Journal of Hazardous Materials found that plastic films, including polypropylene, release microplastics. These particles are considered hazardous and can have health consequences. Within just 15 minutes, the plastic lining begins to degrade. Consuming just three hot beverages a day from these cups could result in ingesting up to 75,000 microplastic particles.
The microplastics released from disposable cups during daily use pose a potential threat to both ecosystems and human health. These cups are typically made of plastic or plastic-coated paper, with the plastic coating accounting for about 5% of the cup. The release of microplastics into the containing beverages has been detected across different cup types, including polyethylene (PE)-coated paper cups, polypropylene (PP) cups, and polystyrene (PS) cups.
High temperatures promote the release of microplastics from disposable cups. The use of acidic carbonated beverages also enhances the release of microplastics, particularly from PE-coated cups. Microplastics have been detected in the range of 675-5984, 781-4951, and 838-5215 particles/L for PE-coated paper cups, PP cups, and PS cups, respectively, when containing pure water at 95°C for 20 minutes.
Biodegradable alternatives, such as polylactic acid (PLA) cups, have been found to release even higher levels of microplastics compared to conventional polyethylene-lined cups. This is due to the cellulose blending in the manufacturing process. However, it is important to note that the levels of microplastic release may be underestimated in these studies due to the exclusion of nanoparticles and other factors.
The release of microplastics from paper cup linings has significant health implications. Studies have shown that these microplastics can interfere with hormone function and have been linked to reproductive harm, metabolic disturbances, and an increased risk of cancer. Certain bacterial enzymes can degrade the microplastic compounds, but further research is needed to understand the full impact of microplastic ingestion on human health.

Paper cups in landfills
Paper cups are often perceived as a more environmentally friendly alternative to plastic cups. However, this is not always the case. While paper is the most recycled municipal and commercial solid waste material, paper cups are rarely recycled. This is because, to prevent leaks, most paper cups are lined with plastic—usually polyethylene—which cannot be easily separated from the paper during the recycling process. As a result, paper cups often end up in landfills.
In the US alone, 50 billion paper cups are thrown away each year, contributing to a staggering amount of waste. Most of these cups end up in landfills, where they can take more than 20 years to decompose. Even in communities where paper cup recycling is possible, the plastic lining is often discarded into landfills or burned as a coal alternative. This is because the plastic lining cannot be broken down into nutrient-rich soil, making it unsuitable for compost.
The plastic lining in paper cups has also been linked to health concerns. Studies have shown that plastic films release microplastics, which have been associated with reproductive harm, metabolic disturbances, and an increased risk of cancer. When paper cups with plastic linings are disposed of in landfills, these microplastics can leach into the surrounding environment, potentially impacting human and animal health.
To reduce the environmental and health impacts of paper cups, some cities have introduced reusable cup initiatives. For example, Freiburg, Germany, has implemented the Freiburg Cup, a hard-plastic reusable cup that is supplied to participating businesses for a small deposit. Starbucks has also partnered with Closed Loop to develop a recyclable and compostable cup. In addition, individuals can play a role in reducing paper cup waste by opting for reusable cups whenever possible.
