Plastic #6, also known as polystyrene or PS, is notoriously difficult to recycle. PS is often used to make Styrofoam products, such as takeout containers, disposable coffee cups, packing peanuts, coolers, and to-go food containers. While some PS products can sometimes be recycled, they are not always accepted by local recycling programs due to their lightweight nature, which makes them prone to becoming litter. As a result, PS products often end up in the environment, where they can break down into smaller pieces and release toxic chemicals, posing a threat to wildlife and ecosystems.

What You'll Learn
PS plastic is hard to recycle
Polystyrene, also known as PS or Styrofoam, is a popular plastic that is widely used in various industries. It is lightweight, rigid, and has excellent insulation properties. However, PS plastic is known for being difficult to recycle, which raises concerns about its environmental impact.
PS recycling is less common than some other types of plastic, and it is not accepted for recycling in many municipal programs. The process of recycling PS is complicated, expensive, and only sometimes economically feasible. It requires significant resources and investment, and the quality of recycled PS can be lower than that of virgin PS, limiting its usefulness in some applications. In addition, PS is often used in products that are difficult to sanitize, such as takeout containers, which makes them less likely to be accepted for recycling.
The complex nature of PS recycling means that it is not always worth the cost for recycling companies to take hard-to-process PS products like Styrofoam. This means that even if your local area accepts PS for recycling, you may need to use a specialist company to recycle your PS waste. Some companies now offer mail-in programs, where you can send your PS waste to be recycled, and some communities have drop-off programs for PS plastic.
Despite the challenges, there are advantages to recycling PS. It helps to reduce the amount of plastic waste sent to landfills, which can have significant environmental benefits as plastic waste can take hundreds of years to break down and release harmful chemicals. It also helps to conserve natural resources by reducing the need for new plastic production. In addition, the EUMEPS has pledged a 46% recycling rate for PS by 2025, and emerging technologies may make it easier and more cost-effective to recycle PS in the future.

PS plastic is often used in Styrofoam products
Polystyrene (PS) is a synthetic, thermoplastic polymer made from the monomer styrene, which is derived from oil. It was first discovered by German chemist Eduard Simon in 1839, but it wasn't until the 1930s that it became commercially available. In the 1940s, PS was used to make toys and other consumer products, and in the 1950s and 1960s, it became popular in the food service industry due to its excellent insulation properties.
PS foam is lightweight, rigid, and versatile, making it ideal for applications that require thermal insulation, such as in packaging materials and building insulation. It is also inexpensive, which contributes to its widespread use. However, one of the biggest challenges with PS products is their impact on the environment. Due to its lightweight nature, PS can easily find its way into the environment, where it can cause harm to wildlife and natural ecosystems.
Despite being difficult to recycle, PS can be recycled. The recycling process involves collecting and processing PS waste to remove impurities and contaminants. The PS is then melted down and reformed into pellets that can be used to create new products, such as casings for electronics. Recycling PS helps to reduce plastic waste and conserve natural resources, but it is a complex and expensive process that is not widely accepted by municipal recycling programs.

PS plastic is a health hazard
Polystyrene (PS) plastic is a health hazard, particularly when used for food packaging. Styrene, the main component of polystyrene, has been identified by the US Department of Health and Human Services as "reasonably anticipated to be a human carcinogen". Styrene exposure has been linked to increased risks of leukaemia, lymphoma, and other cancers. Over fifty chemical byproducts are released during the manufacturing of polystyrene, contaminating the air, water, and communities that work in and live near these facilities.
The Occupational Safety and Health Administration (OSHA) warns that prolonged or regular exposure to the chemicals that make up polystyrene can lead to negative effects on the central nervous system, with symptoms such as depression, headaches, fatigue, and weakness. It can also potentially cause minor effects on kidney function.
Polystyrene is also a health hazard due to its slow biodegradation rate. It is often found as litter, polluting the environment and posing threats to wildlife and ecosystems. As it breaks down, it can release toxic chemicals, which can be consumed by animals and end up in the human food chain.
In addition, PS plastic is a concern for pregnant women, young children, and unborn babies as the chemicals can disrupt hormones responsible for healthy development. Studies have shown that women exposed to these chemicals are more likely to experience reproductive disorders, and children may face health consequences such as reduced IQ and respiratory diseases.
To minimise exposure to PS plastic, it is recommended to store food and beverages in non-plastic containers and avoid heating food in plastic. Avoiding plastic cups for hot drinks and discarding plastic kitchen utensils is also advised.

PS plastic is lightweight and prone to littering
Polystyrene, or PS plastic, is widely used in various industries. It is a lightweight material that is primarily made of air. Its lightweight composition makes it prone to becoming litter. PS plastic is used to make disposable coffee cups, packing peanuts, coolers, and to-go food containers. These products are often used outdoors, which increases the risk of them becoming litter.
PS plastic is not easily recyclable, which further contributes to its littering problem. Its lightweight nature allows it to be easily carried by wind or water, leading to its presence in wild spaces, oceans, and beaches. The lightweight fragments of PS plastic are commonly found during beach litter surveys, highlighting the extent of its littering issue.
The difficulty in recycling PS plastic stems from its complex and expensive process. It is not accepted by many municipal recycling programs, and even when it is, the recycling process can vary depending on the facility and technology available. This complexity discourages proper disposal, increasing the likelihood of it ending up as litter.
To address the littering problem associated with PS plastic, some cities have banned the use of polystyrene foam in food service. While this has effectively reduced PS plastic use, it has also resulted in an increase in other types of food packaging waste. Additionally, some communities have established PS plastic drop-off programs where people can take their foam waste for recycling.
Overall, the lightweight nature of PS plastic contributes to its littering problem. Its widespread use, combined with the challenges of recycling, increases the likelihood of it ending up in the environment. Efforts to reduce PS plastic litter include bans on its use in certain applications and the development of specialized recycling programs. However, the most effective solution lies in reducing the consumption of single-use plastics and seeking alternative materials whenever possible.

PS plastic recycling methods
PS plastic, also known as polystyrene, is a synthetic thermoplastic polymer that can be found in both foam and solid form. It is a lightweight, rigid, and fragile type of plastic that is fully recyclable. However, it has a reputation for being hard to recycle.
PS plastic is often used in the manufacturing of disposable items such as coffee cups, packing peanuts, coolers, and to-go food containers. Due to its lightweight nature, it easily finds its way into the environment, especially wild spaces and oceans, where it poses a threat to wildlife and natural ecosystems.
The recycling process for PS plastic involves collecting and treating PS waste to remove impurities and contaminants. The cleaned PS plastic is then melted down and reformed into recycled polystyrene granules. These granules can be used to manufacture a range of new products, including casings for electronics, cameras, and video cassettes. Recycled PS plastic is also used in the construction industry as raw materials for resin tiles and in the manufacturing of electronic components and automobile parts.
There are several methods available for recycling PS plastic:
- Curbside recycling: Some communities have curbside recycling collection programs that accept polystyrene for recycling.
- Drop-off programs: Certain communities have established drop-off locations where individuals can take their foam waste to be recycled.
- Mail-in programs: Some companies offer mail-in programs that allow individuals to send their PS plastic waste for recycling.
- Specialized handling: Hard-to-recycle plastics, including Styrofoam, require specialized handling and processing by specific recycling companies.
