Styrofoam and plastic are two commonly used materials with negative impacts on the environment. While Styrofoam is a type of plastic with a lower carbon footprint during production, it is not widely recyclable and can harm human health. On the other hand, plastic is more recyclable but requires more energy and chemicals for production and recycling. The answer to which is worse depends on various factors, including lifecycle emissions, landfill environmental cost, and the potential for reuse.

What You'll Learn
Styrofoam is a type of plastic with bubbles in it
Styrofoam is a trademarked brand of closed-cell extruded polystyrene foam, or XPS, and is used for building insulation, thermal insulation, and water barriers. It is owned and manufactured by The Dow Chemical Company. Styrofoam is made from styrene, a petroleum-based product. Through polymerization, styrene is refined into polystyrene, and then a hydrofluorocarbon agent is added.
The process of creating plastic castings from Styrofoam involves dissolving the Styrofoam in acetone, which turns into a goo that can be placed into a mold. However, this often results in bubbles forming in the final product, which can be prevented by using a solvent that polystyrene dissolves in, such as xylene or limonene.
While Styrofoam is recyclable, it is often considered harmful to the environment due to its single-use nature. However, some argue that it may be better for the environment than other materials, such as paper or plastic, as it does not produce methane gas in landfills and can be locally disposed of.

Plastic uses many chemicals to create
Styrofoam is a type of plastic with bubbles in it. It is produced from polystyrene, while other plastics are made from hydrocarbons derived from crude oil, natural gas, and coal.
The process of polymerisation involves using hydrocarbons such as ethylene, which is a gas. When it is subjected to heat, pressure, and a catalyst, it joins together into long, repeating carbon chains. For instance, polymerisation of ethylene into polyethylene (PE) involves adding initiators to start the chain reaction. After the formation of PE, some chemicals (antioxidants and stabilisers) are added. An extruder then converts the PE into strings, and grinders convert it into PE pellets, which factories melt into the final product.
The types of raw materials used to make plastics differ, and it is difficult to say exactly how much of the final product is harmful. However, studies have shown that plastics contain as many as 10,500 chemicals, including Bisphenol A, Propoxy, Dibenzoylmethane, and Diiodomethane. Many of these substances are poisonous.
The use of non-toxic and degradable materials as raw materials will also reduce the degree of white pollution. Polyethylene, polypropylene, and melamine are non-toxic chemicals used in the manufacture of plastics. These raw materials are considered safe to use in food containers such as plastic water bottles and baby bottles.

Plastic recycling causes emissions
When comparing the environmental impact of plastic and styrofoam, one crucial aspect to consider is the emissions generated during the recycling process. Plastic recycling can indeed reduce the amount of plastic waste sent to landfills and contribute to a more circular economy. However, it is important to acknowledge that the process of recycling plastic is not without its environmental costs.
The recycling of plastic requires a significant amount of energy, and this energy is often derived from fossil fuels, which results in the emission of greenhouse gases, particularly carbon dioxide. The exact amount of emissions generated can vary depending on the type of plastic being recycled and the efficiency of the recycling process. For example, the energy required to recycle PET (polyethylene terephthalate) plastic, commonly used in beverage bottles, is estimated to be roughly half of the energy needed to produce new PET plastic. On the other hand, recycling processes for certain complex plastics or mixed plastic waste streams may be more energy-intensive.
The transportation of plastic waste to recycling facilities also contributes to emissions. Collecting, sorting, and transporting plastic waste often involve fossil fuel-powered vehicles, adding to the carbon footprint of the recycling process. Additionally, if the recycling facilities are located far from the sources of plastic waste, the transportation emissions can further increase.
Moreover, plastic recycling can lead to indirect emissions through the displacement of fossil fuel use. When recycled plastic is used in place of virgin plastic, it reduces the demand for new plastic production, which can result in a decrease in fossil fuel extraction and refining. However, this also means that the emissions associated with those processes are shifted elsewhere, potentially to other industries or energy sectors.
It is worth noting that the emissions from plastic recycling are not limited to carbon dioxide. Depending on the specific recycling process and the additives or chemicals used in plastic production, there may also be emissions of volatile organic compounds (VOCs), hazardous air pollutants, or greenhouse gases with a higher warming potential than carbon dioxide, such as methane or nitrous oxide.
In conclusion, while plastic recycling can play a role in reducing plastic waste and promoting sustainability, it is important to recognize that it is not a zero-emissions process. To fully assess the environmental impact of plastic versus styrofoam, a comprehensive life cycle assessment would be necessary, taking into account the emissions from production, use, disposal, and recycling of each material, as well as other environmental factors beyond emissions alone.

Styrofoam has a lower carbon footprint than plastic
Styrofoam, or Expanded Polystyrene (EPS), has been a popular choice for packaging for over 50 years. It is lightweight, sturdy, and capable of preserving temperature, resisting water, and absorbing shocks. These qualities make it ideal for packaging and transporting perishable items. However, with growing environmental concerns, the sustainability of Styrofoam has come into question, particularly when compared to plastic.
While Styrofoam is a type of plastic, it has a lower carbon footprint than other plastics due to its lightweight nature. According to Trevor Zink, an assistant professor of management at the Institute of Business Ethics and Sustainability, Styrofoam has a lower overall lifecycle impact than other packaging materials. Its light weight results in lower production and transportation impacts, reducing the carbon footprint associated with the production and distribution of packaging materials.
Additionally, Styrofoam is easily recyclable and can be incorporated into new packaging products, reducing the demand for virgin materials. This further minimizes the carbon footprint of Styrofoam compared to plastic alternatives that are not as easily recyclable.
However, it is important to note that the recyclability of Styrofoam depends on the context. For example, the City of New York determined that recycling Styrofoam was not economically feasible or environmentally effective, as the majority of Styrofoam collected for recycling ended up in landfills anyway, at a higher economic and environmental cost than direct landfilling.
Despite this challenge, some organizations are seeking sustainable alternatives to Styrofoam. For instance, Stora Enso, a company with a rich history, has shifted its focus to the field of renewable materials. By embracing compostable, biodegradable, and recyclable alternatives, we can reduce our reliance on single-use products and create a more sustainable future.

Styrofoam is not widely recyclable
Styrofoam is a type of plastic with a lot of little bubbles in it. It is made from polystyrene, which is derived from petroleum. While Styrofoam is technically recyclable, it is not widely accepted by recycling programs due to its density and contamination. Polystyrene foam is about 95% air, making it bulky and not cost-effective for storage or shipping. It is often contaminated with food or drink and is challenging to clean due to its porous nature.
The manufacturing process for Styrofoam produces pollutants, including ground-level ozone and other toxic waste. Styrene, a primary component of Styrofoam, is considered a health threat to humans and a probable carcinogen by the World Health Organization's International Agency for Research on Cancer. Due to these concerns, some communities are transitioning from polystyrene to recyclable or compostable products for drinks and food-to-go.
The recyclability of Styrofoam is further complicated by its lightweight nature, which makes it easily blown away and contributes to litter and environmental pollution. Some local governments and recycling companies have designated drop-off locations specifically for foam packaging, but these options may not always be convenient or accessible to individuals.
While Styrofoam is challenging to recycle, it can be reused in various ways. For example, it can be reused for packing up boxes when mailing items or moving. However, the best solution to the Styrofoam recycling problem is to avoid using it altogether. Individuals can bring their reusable cups and containers, choose reduced packaging options, and buy from brands that use biodegradable packaging.

Frequently asked questions
Styrofoam is a kind of plastic, but it is not widely recyclable. Plastic, on the other hand, can be recycled and reused. However, recycling plastic causes emissions as it is transported to third-world countries, and more energy is used in the process of recycling. Styrofoam has a lower carbon footprint than plastic and is better for the environment than paper as it does not produce methane gas when put into a landfill. Overall, styrofoam has a lower environmental impact than plastic if it is thrown away, but plastic is better for the environment if it is reused.
Over fifty chemical byproducts are released during the manufacturing of polystyrene, contaminating the air, water, and communities surrounding these facilities. The US Department of Health and Human Services identifies styrene, a main component of polystyrene, as a potential human carcinogen, with exposure linked to increased risks of leukemia, lymphoma, and other cancers. Styrene can also leach out of styrofoam containers, especially when exposed to hot liquids, acidic foods, or alcohol, and interfere with hormonal functions.
Both plastic and styrofoam have negative impacts on the environment. Plastic uses many chemicals in its creation, and when not disposed of properly, can harm animals who mistake it for food. Styrofoam is difficult to recycle and compost due to its resistance to decomposition, and it can take up to 500 years to decompose, leaching harmful chemicals as it does so.
Styrofoam has a lower carbon footprint than plastic, and it requires fewer materials and less energy to produce. Therefore, styrofoam may be cheaper to produce than plastic. However, this comparison assumes that the cost of the materials and energy used in production is a significant factor in the overall cost of the product, which may not be the case. Other factors, such as labour costs, transportation costs, and economies of scale, may also play a role in determining the final price of plastic and styrofoam products.
