Number 6 polystyrene, commonly known as Styrofoam, is a type of plastic identified by a #6 PS symbol. It is widely used in food packaging and takeaway containers due to its lightweight, rigid, and inexpensive nature. However, its widespread use has raised concerns due to its potential harm to human and environmental health. While it is technically possible to recycle Styrofoam, it is not always accepted by home recycling programs, and specialist recyclers may only take clean, white polystyrene. With the presence of Styrene, a component of Styrofoam, found in 100% of human fat tissue samples since 1986, it is important to reduce the use of Styrofoam and transition to more environmentally-responsible alternatives.

Polystyrene is identified as Plastic No. 6 and is commonly used in food packaging
While polystyrene is recyclable, it is not always accepted by home recycling programs and may need to be taken to a specialist recycler. It is important to ensure that any polystyrene being recycled is clean and free of any tape, plastic film, labels, or glued-on cardboard. It should also be separated from other recycling and broken or cut into small pieces. However, even where polystyrene is recycled, takeout containers are often not accepted due to the difficulty of sanitizing them.
The use of polystyrene has come under scrutiny due to its potential harm to human and environmental health. Styrene, a component of polystyrene, has been found in 100% of human fat tissue samples dating back to 1986 and is known to cause cancer in animals. It is also suspected to be both carcinogenic and a neurotoxin for humans. Additionally, polystyrene is fragile and can easily break up into tiny pieces that can end up on beaches and in the ocean, where it can be consumed by marine creatures.
Due to the environmental and health concerns associated with polystyrene, some organizations, such as the Green Dining Alliance, have banned its use in restaurants. The city of New York has also banned the use of polystyrene, and it has been restricted by the University of California and banned in 116 cities across California. Despite its cheap price point and lightweight properties, it is important to reduce the use of polystyrene and opt for more environmentally responsible alternatives.

Styrofoam is a trademarked brand of polystyrene
Styrofoam is a trademarked brand name for polystyrene, a type of plastic. Polystyrene is identified as Plastic No. 6 and is commonly used in food packaging and lab equipment. It is made from the monomer styrene, which is derived from oil. These monomers are polymerized to form polystyrene.
The Dow Chemical Company developed a new process to create polystyrene and trademarked it as Styrofoam. Styrofoam is composed of 98% air, making it lightweight and buoyant. It is used in a variety of applications, including building insulation, craft products, and packaging.
While polystyrene can be recycled, it is not always accepted by local recycling programs. It is important to separate polystyrene from other recyclables and ensure it is clean and free of any tape, plastic film, or labels before recycling. Some specialist recyclers only take clean, white polystyrene.
The use of polystyrene has been banned by organizations like the Green Dining Alliance due to its harmful effects on human and environmental health. It is important to reduce the use of polystyrene and opt for more environmentally-friendly alternatives whenever possible.
Overall, while Styrofoam is a well-known brand name for polystyrene, it is important to be aware of the environmental impacts of this type of plastic and take appropriate steps to reduce, reuse, and recycle it.

Plastic No. 6 is hard to recycle and is harmful to human health
Plastic No. 6, also known as polystyrene, is a type of plastic identified by a #6 "PS" symbol and includes all foam products like Styrofoam and some hard plastics like disposable straws and flatware. While it is technically possible to recycle this type of plastic, it is not always accepted by local recycling programs and can be challenging to recycle due to its lightweight and fragile nature.
One of the biggest challenges with recycling Plastic No. 6 is that it is often not labelled, especially in packaging. As a result, consumers may not realize that a product is made from polystyrene and may inadvertently contaminate the recycling stream. In addition, even when polystyrene is properly separated from other recyclables, it is often only accepted by specialist recyclers if it is clean, free of any tape or labels, and broken down into small pieces.
Another issue with Plastic No. 6 is that it is cheap to produce and lightweight, making it widely used in packaging and insulation. This contributes to the widespread presence of polystyrene in the environment, as it is prone to escaping into wild spaces and oceans, where it poses threats to wildlife and natural ecosystems. The lightweight nature of polystyrene also means that it can be easily carried by wind or water, leading to its accumulation in remote areas.
The fragility of Plastic No. 6 is also a concern, as it breaks up easily and can enter the environment in tiny pieces. These microplastics have been found in beaches, marine creatures, and even human brain samples. In addition, polystyrene can leach potentially toxic chemicals, especially when heated, posing health risks to those who consume food or beverages packaged in this material. Due to these concerns, some cities have banned the use of polystyrene foam for food service, and organizations like the Green Dining Alliance require members to ban polystyrene.
While recycling Plastic No. 6 can be challenging, there are some options available. Some communities have drop-off programs or mail-in programs that accept polystyrene foam for recycling. However, it is always preferable to reduce, reuse, or rebuy recycled products to minimize the environmental and health risks associated with this type of plastic.

Polystyrene is lightweight, rigid, and inexpensive
Polystyrene, also known as Plastic No 6, is identified with a “PS” symbol and is commonly used in takeaway food packaging. It is lightweight because it is made up of more than 95% air. It is also versatile and inexpensive. Its lightweight property also makes it cheap to ship.
Polystyrene is used for producing disposable plastic cutlery and dinnerware, CD "jewel" cases, smoke detector housings, license plate frames, plastic model assembly kits, and many other objects where a rigid, economical plastic is desired. Its rigidity and toughness make it ideal for use in children's seats and cycling helmets.
Polystyrene is also used in the manufacture of sliders, model planes, and even surfboards because of its positive strength-to-weight ratio. Its compression resistance makes it ideal for stacking packaging goods. It is also used as insulated panel systems for facades, walls, roofs, and floors in buildings, as well as in road and railway construction.
Polystyrene is naturally transparent to visible light, but it can be colored with colorants. It is also optically clear and easily molded. However, it is important to note that polystyrene can be harmful to the environment, and its use should be minimized.

The Green Dining Alliance bans the use of polystyrene in restaurants
The Green Dining Alliance (GDA) is a year-round program of earthday365, a 501c3 nonprofit organization. To become a member of the GDA, a restaurant must meet its Core Concepts, which includes banning the use of all polystyrene. Polystyrene is identified as Plastic No. 6 and features a "6" inside a triangle of arrows, along with the letters "PS". It is commonly used in takeaway food packaging and includes all foam products like Styrofoam and some hard plastics like disposable straws, flatware, and bottle caps.
Although polystyrene is lightweight, versatile, and inexpensive, it is very difficult to recycle. Home recycling programs rarely accept it, so it must be brought to specialist recyclers. Even then, it is often not recoverable. Polystyrene is harmful to human and environmental health and is classified as a known hazardous substance. Styrene, a component of polystyrene, has been found in 100% of human fat tissue samples dating back to 1986. It has many ties to cancer and causes developmental, hematological, renal, and immunological disorders. Styrene also evaporates into the air, which is bad for the ozone layer and our lungs.
Given these harmful effects, the GDA encourages restaurant owners to buy more compostable and recyclable products. The GDA has tripled its membership and includes special offers at 18 GDA-certified restaurants. The entire city of New York has also banned polystyrene.
