Styrofoam is a specific variation of expanded polystyrene (EPS) packaging, trademarked by DuPont, and commonly used in egg cartons, takeout containers, and packaging peanuts. With the rise of plastic pollution, many are unsure of how to properly dispose of Styrofoam, questioning whether it belongs with paper or plastic during recycling. While Styrofoam is technically recyclable, it is highly inefficient to do so, as it is lightweight, bulky, and tends to break easily and stick to other materials, contaminating the recycling process.
| Characteristics | Values |
|---|---|
| Environmental impact | Paper cups are generally considered to be more environmentally friendly than polystyrene foam cups as they are made from trees, a renewable resource. However, paper cups are often coated with polyethylene plastic derived from fossil fuels, and the manufacturing process uses more resources and energy. Polystyrene cups are made from non-renewable natural gas and petroleum byproducts, but the manufacturing process uses fewer resources. |
| Decomposition | Paper cups decompose faster than polystyrene foam cups. A standard paper cup can take over 20 years to decompose in a landfill due to the wax lining, while polystyrene can take up to 500 years to break down. |
| Recyclability | Polystyrene cups are technically recyclable as they are made of plastic #6, but many local recycling centers do not accept them due to contamination and a lack of market value. Paper cups intended for hot beverages are often not recyclable due to their coating, but shredded paper can be recycled. |

Paper cups are more expensive to produce and require additional cardboard sleeves
Paper cups are more expensive to produce and often require additional cardboard sleeves, which further increases their cost. Paper cups cost around two-and-a-half times the amount of a Styrofoam cup to produce. They require 12 times the amount of water, 36 times the electricity, and double the money to manufacture compared to polystyrene cups. In addition, the inclusion of a cardboard sleeve adds 2-3 cents to the cost of each cup.
The higher cost of paper cups is due to the materials and processes involved in their production. Paper cups are made from trees, a renewable resource, and coated with polyethylene plastic derived from fossil fuels. The coating acts as a moisture barrier, but it also makes the cups difficult to recycle. The complex and expensive recycling process for paper cups involves separating the lining from the cup before the paper portion can be recycled. As a result, many paper cups end up in landfills or incinerators.
Cardboard sleeves are often used with paper cups to prevent consumers from burning their fingers when holding hot beverages. While most sleeves are made from recycled materials and are recyclable, they contribute to the overall cost and environmental impact of paper cups. The production of sleeves requires additional raw materials, energy, and shipping.
The environmental impact of paper cups is further evident in the habitat loss and waste generated during their production. It is estimated that over 6.5 million trees were cut down to make 16 billion paper coffee cups used in the US in 2006, resulting in 253 million pounds of waste. Additionally, the CO2 emissions from a single 16-ounce paper coffee cup with a sleeve are about 0.253 kilograms.
While paper cups might seem like a more environmentally friendly option due to their renewability, the additional resources, energy, and cost required for their production and recycling make them less favourable than Styrofoam cups in some ways. However, it is important to consider the potential health and environmental risks associated with Styrofoam, such as the leaching of harmful chemicals like benzene when microwaved. Ultimately, the best choice for the environment is to use a reusable cup whenever possible.

Polystyrene cups are made from non-renewable natural gas and petroleum byproducts
Polystyrene cups, commonly referred to as Styrofoam cups, are made from non-renewable natural gas and petroleum byproducts. This is in contrast to paper cups, which are made from trees, a renewable resource.
The choice between using polystyrene or paper cups is a complex one, with various factors to consider. While paper cups are generally considered the better option, this is not always the case when other environmental factors are taken into account. For example, the manufacturing process for polystyrene cups uses fewer resources and is therefore more environmentally friendly than that of paper cups. Paper cups require more energy, raw materials, and money to produce. They also need to be disposed of carefully, as they are coated with polyethylene plastic, derived from fossil fuels, which can release methane, a harmful gas, into the atmosphere.
On the other hand, polystyrene cups can leach harmful chemicals, such as benzene, especially when heated in a microwave. Additionally, animals may mistake them for food and consume them. Paper cups, on the other hand, are not toxic, even when accidentally ingested.
The best choice for the environment is to use a reusable cup, rather than disposable polystyrene or paper cups. However, if a disposable cup is necessary, it is important to consider the specific environmental impacts of each type of cup, as well as the availability of biodegradable options.
In summary, while polystyrene cups are made from non-renewable natural gas and petroleum byproducts, the choice between polystyrene and paper cups is not clear-cut and requires a consideration of various factors to determine the most environmentally friendly option.

Paper cups decompose faster and are easier to recycle than polystyrene cups
When it comes to the environmental impact of disposable cups, there are several factors to consider, including the materials used, recyclability, decomposition rate, and toxicity. While polystyrene cups, often referred to as Styrofoam cups, have certain advantages, paper cups do have some benefits in terms of decomposition and recyclability.
Paper cups are generally believed to be more environmentally friendly than polystyrene cups, primarily because they are made from trees, a renewable resource. However, it is important to note that most paper cups are coated with polyethylene, a plastic derived from fossil fuels, reducing this advantage. Despite this, paper cups still have a faster decomposition rate compared to polystyrene cups. A standard paper cup can take over 20 years to decompose in a landfill due to the wax or plastic lining, whereas biodegradable paper cups can decompose within six months under the right conditions, such as in industrial composting facilities. In contrast, polystyrene cups are made from non-renewable natural gas and petroleum by-products.
The recyclability of paper cups is a complex issue. While paper cups are technically recyclable, the plastic or wax lining makes it challenging to recycle them through standard recycling facilities. This lining is difficult to separate from the paper during the recycling process, leading to increased costs and contamination of other recyclable materials. However, there are efforts to improve paper cup recycling, with some communities implementing cup recycling projects in closed environments like shopping centres and airports. These projects aim to collect, bail, and separate the lining, but even in these cases, the separated plastic lining often ends up in landfills or is burned. Biodegradable paper cups offer a more sustainable alternative, as they can be turned into organic compost.
Polystyrene cups, on the other hand, have a more straightforward recycling process and use fewer resources during manufacturing, making them more environmentally friendly in that aspect. However, they face challenges in terms of decomposition and toxicity. Polystyrene cups can take a long time to break down and may leach harmful chemicals like benzene, especially when microwaved. Animals may also mistake them for food and consume them. In contrast, paper cups, even those with polyethylene coatings, are not toxic, even when heated or ingested accidentally.
While the choice between paper and polystyrene cups is complex and depends on various factors, paper cups do have the advantage of faster decomposition and easier recyclability under specific conditions. However, the best environmental choice is to use a reusable cup whenever possible, reducing the need for disposable cups altogether.

Polystyrene cups can leach harmful chemicals, especially when microwaved
When it comes to choosing between paper and polystyrene cups, there are several factors to consider, including environmental impact, cost, and health risks. While paper cups are generally considered a better choice, the decision is not always straightforward.
Polystyrene cups, often referred to as Styrofoam cups, have better insulation properties than paper cups. They are also more cost-effective and environmentally friendly during the manufacturing process, requiring fewer resources. However, one significant concern with polystyrene cups is their potential health risk, especially when microwaved.
Polystyrene cups can leach harmful chemicals, such as benzene and styrene, into the food or drink they contain, especially when heated in a microwave. Styrene, a compound found in polystyrene, has been linked to cancer in both animal and human studies. Therefore, it is recommended to avoid microwaving polystyrene products unless they are clearly marked as microwave-safe.
On the other hand, paper cups have their own advantages and disadvantages. They are made from trees, a renewable resource, and decompose faster than polystyrene cups. However, most paper cups intended for hot beverages are not recyclable due to the wax lining on the inside, which lengthens their decomposition time in landfills. Additionally, paper cups often require additional components, such as cardboard sleeves, to prevent consumers from burning their fingers, further increasing their environmental impact and cost.
While the choice between paper and polystyrene cups may depend on various factors, it is essential to prioritize health and safety. Therefore, it is generally advisable to avoid microwaving polystyrene cups due to the potential risk of harmful chemical leaching. Instead, consumers can opt for reusable cups or biodegradable paper cups, prioritizing both health and environmental sustainability.

Paper cups are coated with polyethylene plastic derived from fossil fuels
Paper cups are often considered a more environmentally friendly alternative to polystyrene cups (commonly known as Styrofoam cups). However, the environmental benefits of paper cups are minimal, and one key factor that reduces their advantage is the coating used on paper cups.
Most paper cups are coated with polyethylene plastic, which is derived from fossil fuels. Polyethylene is used to provide durability and water resistance to the paper cups, as paper is not naturally resistant to water or fats. This coating ensures that the paper cup can contain liquids without leaking. While polyethylene is commonly used, there are also other types of coatings used for paper cups, such as polylactide (PLA), a bioplastic made from renewable resources like corn, cassava, or sugarcane.
The use of fossil fuels in the production of paper cups reduces their environmental advantage over polystyrene cups, which are made from natural gas and petroleum, both non-renewable resources. The manufacturing process for polystyrene cups generally uses fewer resources and is considered more environmentally friendly than that of paper cups. However, it is important to note that paper cups decompose faster and are easier to recycle than polystyrene foam cups.
Another important consideration is the potential toxicity of the cups. Polystyrene cups can leach harmful chemicals, such as benzene, especially when microwaved, posing a risk to both humans and animals. On the other hand, paper cups, including those coated with polyethylene or PLA, are not toxic, even when microwaved or accidentally ingested.
While the use of polyethylene plastic derived from fossil fuels in paper cups reduces their environmental advantage, it is important to consider the overall impact by evaluating various factors, such as recyclability, toxicity, and decomposition rates, to make an informed decision about the choice between paper and polystyrene cups.
