What You'll Learn
Polystyrene can be recycled, but it is not widely practised
Plastic number 6, also known as polystyrene, can be recycled. However, it is not widely practised. Polystyrene is a versatile plastic polymer that is widely used in a variety of industries. It is a hard, brittle plastic that can be easily moulded into different products, shapes, and foam materials. Due to its lightweight yet robust nature, polystyrene is commonly used for protective packaging, especially for fragile items. It is also prevalent in the food industry, where its insulating properties help keep food fresh during transportation.
Despite its recyclability, polystyrene recycling is not widely available. Most local councils and home recycling programs do not offer this service, and specialist recyclers are usually required. The lack of demand for recycled polystyrene is a significant obstacle to its widespread recycling. There are few markets for recycled polystyrene products, making it challenging for recycling facilities to justify the expense of processing it. Additionally, the varying density, bulkiness, and composition of polystyrene, which can be up to 98% air, often make it uneconomical for recyclers to collect.
The process of recycling polystyrene can be complex and challenging. It is difficult to separate the different types of polystyrene during recycling, and contamination with food or other substances complicates the process. Polystyrene's lightweight and buoyant nature also means it can easily be dispersed by wind and water, leading to widespread pollution. Its persistence in the environment has led several cities and countries to ban its use, particularly in the food industry.
To improve the recyclability of polystyrene, businesses can invest in polystyrene compactors, which reduce the volume of waste and make it more economical to transport and recycle. Additionally, consumers can play a role by reducing their use of polystyrene, reusing it where possible, and opting for safer types of plastic or alternative materials such as metal and glass.

It is identified by a #6 PS symbol
Plastic #6, identified by the #6 PS symbol, is polystyrene, a type of plastic that is challenging to recycle. It is often found in foam packaging, disposable coffee cups, packing peanuts, coolers, and
Polystyrene is one of the least recycled plastics, with a rate of less than 1%. While it is technically possible to recycle polystyrene, it is not as easily accessible to individuals. Most home recycling programs do not accept it, so it usually needs to be taken to a specialist recycler. Even if it is recycled, polystyrene can be harmful when it gets into the environment, so it is best to minimise its use.
The Green Dining Alliance, for example, requires its members to ban the use of all polystyrene. Polystyrene is also banned in the entire city of New York. Despite this, polystyrene products are still widely used due to their low price and lightweight, cheap shipping.
To identify polystyrene, look for the #6 PS symbol. It is often found on foam products like Styrofoam and some hard plastics like disposable straws, flatware, and bottle caps. Polystyrene is challenging to recycle because it is difficult to manage and has very little value as a post-consumer commodity.

It is harmful to the environment and humans
Polystyrene, a plastic categorized under the resin identification code 6, poses significant risks to both the environment and human health. Often used in disposable food and beverage packaging, this material has detrimental effects due to its toxic nature and persistence in the natural world.
To begin with, polystyrene is harmful to the environment at every stage of its life cycle. The production of this plastic requires the use of toxic chemicals, including styrene, a known carcinogen. During manufacturing, these hazardous substances can be released into the air and water, contaminating ecosystems and endangering various species. Even when polystyrene is disposed of responsibly, its impact on the environment doesn't end. This plastic is lightweight and easily fragmented, leading to the potential for wind-borne dispersal over large areas. The persistence of polystyrene in the environment is another concerning factor, as it does not readily biodegrade. Instead, it breaks down into microplastics over time, which can be ingested by animals and accumulate in their tissues, leading to potential toxic effects and disruption of ecosystems.
The human health risks associated with polystyrene are also cause for alarm. When heated, polystyrene containers can leach toxic chemicals, including styrene monomers and benzene, into food and beverages. These chemicals have been linked to various health issues, including cancer, neurological problems, and hormonal imbalances. Additionally, the use of polystyrene in food packaging increases the risk of chemical migration into foods, especially when the plastic comes into contact with fatty substances. This can lead to the ingestion of harmful chemicals, with potential long-term health consequences.
Furthermore, the widespread use of polystyrene in single-use disposable products contributes to the growing problem of plastic pollution. As this plastic is not commonly recycled, it often ends up in landfills or the natural environment, where it persists for extended periods. The accumulation of plastic waste not only impacts wildlife and ecosystems but also has negative aesthetic effects on natural landscapes. The presence of polystyrene waste in our environment is a stark reminder of the urgent need to transition towards more sustainable and eco-friendly alternatives.
In conclusion, polystyrene, identified as plastic type 6, presents a range of environmental and human health hazards that cannot be overlooked. From its toxic production process to its persistence in the environment and potential to leach harmful chemicals, the impacts are far-reaching. To mitigate these risks and create a more sustainable future, it is essential to reduce the use of polystyrene and prioritize the development and adoption of safer, biodegradable alternatives. By doing so, we can minimize the harmful effects of this plastic on our planet and protect the health and well-being of current and future generations.

It is rarely labelled, especially in packaging
Plastic #6, also known as polystyrene, is a type of plastic that is often found in foam packaging or food containers. It is also commonly used in takeaway food packaging and recognised as the white foam blocks in packaging or packing peanuts. Polystyrene is identified by a #6 "PS" symbol and includes all foam products like Styrofoam and some hard plastics like disposable straws and flatware.
It is important to note that polystyrene is rarely labelled, especially in packaging. This makes it harder for consumers to recognise and properly recycle this type of plastic. Properly disposing of polystyrene is crucial as it can be harmful to the environment and human health when it ends up in the environment.
Polystyrene can be recycled, but it is not as easily accessible as other types of recycling. Curbside recycling programs usually don't accept polystyrene because it is challenging to manage. Specialist recyclers are typically required for polystyrene, and they will only take clean, white polystyrene free of any tape, plastic film, labels, loose parts, or glued-on cardboard.
To recycle polystyrene, separate it from your regular recycling and break or cut it into small pieces. Then, find a local specialist recycler that accepts polystyrene and drop it off. Some tips to keep in mind are to avoid using polystyrene whenever possible and to opt for safer classes of plastic, especially when it comes to food and drinks.

It is banned by the Green Dining Alliance
Plastic #6, also known as polystyrene, is banned by the Green Dining Alliance. Polystyrene is a type of plastic that can be identified by the #6 "PS" symbol and includes all foam products like Styrofoam and some hard plastics like disposable straws and flatware.
Polystyrene is banned by the Green Dining Alliance because it is toxic and harmful to both people and the planet. According to the Environmental Protection Agency (EPA), styrene leaches from landfills into drinking water, causing liver, kidney, and circulatory system problems. Styrene is also classified as a known hazardous substance and has been linked to cancer. In addition, styrene fumes evaporate into the air, which is detrimental to both our lungs and the ozone layer.
Furthermore, polystyrene is challenging to recycle. While it is technically recyclable, it is not always accepted by local recycling programs or curbside recycling services. This means that people often need to find specialist recyclers to recycle their polystyrene waste, which can be inconvenient and time-consuming.
The Green Dining Alliance is a year-round program of earthday365, a 501c3 nonprofit organization. To become a member of the Green Dining Alliance, a restaurant must meet their Core Concepts, which includes banning the use of all polystyrene products. By banning polystyrene, the Green Dining Alliance is taking a stand against the use of toxic and environmentally harmful plastics and encouraging the use of more sustainable alternatives.
