What You'll Learn
Paper cups are coated with plastic
Paper cups are often coated with plastic, which can cause environmental and health issues. The plastic coating is necessary to make the paper cups water-resistant, as paper is not naturally resistant to water or fats. Traditionally, paper cups for hot drinks were made waterproof by spinning clay inside the cup at high speed, but this resulted in drinks tasting and smelling like cardboard. Paper cups for cold drinks were coated with wax to prevent condensation from soaking into the cup. However, these coatings were replaced by polyethylene (PE)-coated cups, which are now the most common type of paper cup. This plastic coating is often very thin and made of polylactide (PLA), a type of bioplastic derived from renewable resources such as corn, cassava, or sugarcane. While PLA is considered biodegradable, research suggests that it can still be toxic and persist in the environment, leading to the ingestion of microplastics by animals and humans.
The plastic coating on paper cups has negative environmental implications. Due to the plastic content, paper cups are rarely recycled or composted because separating the polyethylene during recycling is challenging. As a result, paper cups often end up in landfills or are incinerated. In addition, paper cups that are lined with PLA can contaminate the waste stream, making other recycled plastics unsaleable. This issue has prompted the development of alternative coatings, such as EarthCoating by Smart Planet Technologies, which is certified as universally recyclable in conventional paper recycling systems. However, even with these advancements, the overall carbon footprint of paper cups compared to other disposable or reusable options is still a subject of debate.
The use of plastic coatings on paper cups also raises health concerns. Studies have shown that chemicals can leach from paper cups into liquids, potentially harming those who consume them. For example, researchers at the University of Gothenburg found that disposable paper and plastic cups negatively affected the growth of mosquito larvae when left in water for a few weeks. This indicates that the chemicals in paper cups can have toxic effects on living organisms, similar to those observed in plastic pollution. As a result, the shift towards alternative materials like paper cups may not be as beneficial as initially believed.
While the plastic coating on paper cups serves a functional purpose, it has become a significant environmental and health concern. The difficulty in recycling and disposing of these cups contributes to waste accumulation and pollution. Additionally, the leaching of chemicals from the plastic coating poses potential risks to human health. These issues highlight the need for further research and the development of more sustainable and safe alternatives to plastic and paper cups.

Paper cups are just as toxic as plastic cups
While plastic cups are known to contain toxic chemicals, paper cups are also just as toxic. Paper cups are neither fat nor water-resistant, so they need to be treated with a surface coating, often made of plastic. This plastic layer can contain toxic chemicals that can leach into liquids and harm living organisms.
The shift away from plastic to paper cups is driven by the perception that paper is a more environmentally friendly alternative. However, the reality is that paper cups can also be harmful to the environment and human health. Researchers at the University of Gothenburg found that paper cups, like plastic cups, negatively impacted the growth of mosquito larvae when exposed to tainted water. This finding highlights the toxic nature of paper cups, which can have similar detrimental effects on living organisms as plastic cups.
The plastic coating on paper cups is typically made of polyethylene or polypropylene, which can leach chemicals when in contact with liquids. These chemicals can then be ingested by humans and animals, posing potential health risks. Additionally, the process of manufacturing paper cups often involves the use of processing aids, heat stabilizers, and other substances known to be toxic. Even plant-derived materials used in paper cups, such as polylactic acid (PLA), can be contaminated by additional chemicals during processing.
The recycling of paper cups is also challenging due to the difficulty of separating the plastic coating from the paper. As a result, most paper cups end up in landfills, where they may not decompose properly and can release methane. While some companies have developed recyclable coatings, such as EarthCoating, the majority of paper cups still contribute to waste and environmental pollution.
To reduce the toxic effects of both plastic and paper cups, it is recommended to shift away from disposable lifestyles. Reusable options, such as bringing one's mug or using a porcelain mug, are more environmentally friendly and reduce the potential health hazards associated with single-use cups. By moving away from disposable products, we can minimize the negative impact on the environment and our health.

Paper cups are not recyclable
Plastic cups and paper cups are related in that they are both used as single-use, disposable containers for liquids, often for beverages such as coffee or soda. With growing concerns about plastic pollution, many people are shifting towards using paper cups as a more environmentally friendly alternative. However, the idea that paper cups are a sustainable option is problematic.
The plastic coating on paper cups is also problematic because, despite being made from renewable resources and being biodegradable, it can still be toxic to the environment. A study by researchers at the University of Gothenburg found that disposable paper cups, when left in wet sediment and water for a few weeks, negatively affected the growth of mosquito larvae. This indicates that the chemicals in the paper cups can leach out and harm living organisms if the cups end up in nature.
Furthermore, the use of paper cups can contribute to deforestation and increased carbon emissions. Paper cups are made from wood chips or wood fiber from trees in sustainably managed forests, which can lead to deforestation if not properly regulated. Additionally, the production, processing, and shipping of paper cups can result in significant carbon dioxide emissions.
While some companies have developed new coatings for paper cups that are certified as universally recyclable, such as Smart Planet Technologies' EarthCoating, these cups are still not widely available. Most paper cups continue to be coated with plastic, making them difficult to recycle and contributing to environmental pollution if not disposed of properly.
Therefore, it is important to recognize that paper cups, while seemingly more environmentally friendly than plastic cups, are not a fully sustainable solution. To reduce waste and minimize our environmental impact, it is recommended to bring one's own reusable mug or cup when purchasing takeaway beverages.

Plastic cups have a smaller carbon footprint than paper cups
Plastic cups and paper cups are related in that they are both commonly used for disposable drinking vessels. However, the environmental impact of each option varies significantly. While plastic cups are made from petroleum-based materials, paper cups are often coated with plastic, usually polyethylene (PE) or polylactide (PLA), a bioplastic made from renewable resources. This coating helps to waterproof the paper and improve its durability.
The production of plastic cups contributes to the significant issue of plastic pollution, which has contaminated all parts of the Earth and affected all living things. Plastic waste can take the form of microplastics, which can be ingested by animals and humans, causing unknown health risks. In addition, the production of plastic often involves the use of fossil fuels, contributing to greenhouse gas emissions.
On the other hand, paper cups have been promoted as a more environmentally friendly alternative to plastic cups. Paper is derived from wood chips, which are considered a renewable resource. However, the process of manufacturing paper cups requires the use of inorganic chemicals and results in large amounts of water effluents. Additionally, paper cups are typically designed for single-use and are challenging to recycle due to the plastic coating.
Despite these considerations, plastic cups may have a smaller carbon footprint than paper cups in certain scenarios. For example, a study by Huhtamaki found that a reusable plastic cup should be used at least 20 times to have a lower climate impact than a paper cup. This break-even point increases to 32-36 times if the paper cup is recycled or made with a plant-based coating. The study also concluded that paper cups have the lowest carbon footprint when compared to ceramic or steel cups, especially in a coffee-to-go scenario.
Furthermore, the carbon footprint of a paper cup is relatively small compared to the food or beverage it holds. For instance, in the case of a takeaway latte, the paper cup accounts for only 4% of the climate impact, with the remaining 96% attributed to coffee and milk production and the energy required to make the drink. This perspective highlights how the choice of cup material is just one factor in the overall environmental impact of our consumption habits.

Paper cups are biodegradable
While plastic cups are known to be harmful to the environment, paper cups have been proposed as a more environmentally friendly alternative. However, paper cups are not without their drawbacks. Most paper cups are designed for single use and disposal, and very little recycled paper is used to make them due to contamination concerns and regulations.
Paper cups are often coated with plastic, such as polyethylene, to prevent liquids from being absorbed into the paper. This plastic coating makes paper cups difficult to recycle or compost, as the coating cannot be easily separated from the paper during the recycling process. In fact, as of 2016, there were only two facilities in the UK capable of properly recycling PE-coated cups.
However, there are efforts to make paper cups more environmentally friendly. Some companies have developed new coatings, such as EarthCoating, that are engineered to be recycled through traditional paper recycling systems. These coated paper cups have received high ratings for recycling from certifying bodies. Additionally, some paper cups are now made with biodegradable materials, such as polylactic acid (PLA), a renewable resource that can biodegrade in industrial composting facilities without leaving behind toxic residues.
Despite these advancements, there are still concerns about the environmental impact of paper cups. Studies have shown that paper cups can contain toxic chemicals that can harm living organisms if they end up in nature. Additionally, paper cups that are not properly recycled or composted can release methane in landfills.
In conclusion, while paper cups have the potential to be more environmentally friendly than plastic cups, it is important to consider the full life cycle of these products. Proper disposal and recycling infrastructure are crucial to ensuring that paper cups can be a more sustainable option.
