Plastic is ubiquitous in modern life, and it is important to understand the potential harm of different types of plastics. Plastic products are often stamped with a resin code, which is a number between one and seven inside a small triangle made of arrows. Each number corresponds to a different type of plastic. Number 6 plastics, also known as polystyrene or Styrofoam, are found in disposable plates and cups, meat trays, egg cartons, carry-out containers, aspirin bottles, and compact disc cases. They are one of the most difficult plastics to recycle due to their higher melting temperature and low buyer demand for sorted polystyrene.

What You'll Learn
Polystyrene is identified by the #6 PS symbol
Plastic is ubiquitous in the modern world, and it is important to understand the different types of plastic and their potential harm to human health and the environment. Polystyrene is identified by the #6 PS symbol and is one of the most common plastics available. It is extremely lightweight, rigid, versatile, and inexpensive, which explains its popularity. Polystyrene is often found in foam packaging, food containers, disposable plates and cups, meat trays, egg cartons, carry-out containers, and CD cases. It is also used in insulation and some toys.
Polystyrene is notorious for being one of the most difficult plastics to recycle. While it can technically be recycled, it is not always accepted by local recycling programs due to the challenges in managing it. The higher melting temperature of polystyrene also adds to the cost of the recycling process. As a result, there is a low demand for recycled polystyrene, and it is rarely recycled.
To recycle polystyrene, it must be clean and free of any tape, plastic film, labels, loose parts, or glued-on cardboard. It should be separated from other recyclables and cut or broken into small pieces to maximize the amount that can be recycled. Only white polystyrene is typically accepted by recycling facilities, so any coloured foam should be removed.
To identify polystyrene, look for the #6 PS symbol, which indicates the presence of polystyrene plastic. This symbol is typically found on the bottom, top, or side of the plastic object. Polystyrene is also identified by its appearance, often recognized as white foam blocks used in packaging or takeaway food containers.

It includes foam products like Styrofoam
Number 6 plastic, also known as polystyrene, is commonly identified by the "#6 PS" symbol. It is often found in foam products like Styrofoam, which is used in various applications, including food packaging and containers.
Polystyrene is a versatile material that is lightweight, rigid, and inexpensive, making it widely used in packaging and other products. It is recognised as the white foam blocks used in packaging or takeaway food containers. Polystyrene is also used in items like insulation, CD cases, and even some toys.
While polystyrene can technically be recycled, it is challenging to do so. It is rarely recycled due to several factors. Firstly, it has a higher melting temperature, adding to the cost of the recycling process. Secondly, there is a limited market for recycled polystyrene, as it is not in high demand for post-consumer product manufacturing. As a result, despite being accepted by some recycling haulers, polystyrene is often not recoverable.
To recycle polystyrene, it must be clean and free of any tape, plastic film, labels, loose parts, or glued-on cardboard. It should be separated from regular recycling and broken or cut into small pieces to maximise the amount that can be recycled. However, even with these measures, many recycling facilities will only accept white polystyrene, excluding coloured foam.
Due to the challenges associated with recycling polystyrene, it is recommended to avoid using products made from this material. Number 6 plastic is included in lists of plastics to avoid due to potential health risks and the difficulty of disposal.

It is rarely recycled due to its higher melting temperature
Number 6 plastic, also known as polystyrene, is a type of plastic that is rarely recycled due to its higher melting temperature. It is often found in foam products like Styrofoam and some hard plastics like disposable straws, flatware, and CD cases. Polystyrene is lightweight, rigid, versatile, and inexpensive, which makes it a popular choice for packaging and food containers. However, its higher melting temperature adds to the cost of the recycling process, making it less likely to be recycled.
The recycling symbol for number 6 plastic is typically a "PS" symbol within a triangle with chasing arrows and the number 6 in the centre. This symbol can be found on various products, including foam cups, meat trays, egg cartons, carry-out containers, and disposable plates and cups. Despite its presence on these items, number 6 plastic is rarely recycled.
The higher melting temperature of number 6 plastic is a significant factor in its limited recyclability. The process of recycling plastic generally involves melting it down, and a higher melting temperature requires more energy and resources. This increases the cost of recycling number 6 plastic, making it less economically viable for recycling facilities.
Additionally, there is a low demand for recycled number 6 plastic in the market. Unlike other types of plastic, there is not a strong buyer's market for sorted polystyrene. This further discourages recycling facilities from processing number 6 plastic, as they may incur additional costs without a guaranteed return on their investment.
While number 6 plastic can technically be recycled, it is often not accepted by curbside recycling programs due to its challenging nature. Consumers who wish to recycle number 6 plastic may need to seek out specialist recyclers, which can be more time-consuming and inconvenient. As a result, much of this plastic ends up in landfills or deteriorates on land or in water, causing harm to the environment and human health.

It is often found in food containers
Plastic No. 6 is polystyrene, identified by a #6 "PS" symbol. It is often found in food containers, such as takeaway food packaging, clamshell containers, berry containers, and carry-out containers. Polystyrene is also commonly used in foam packaging and products like disposable cups, plates, straws, meat trays, egg cartons, and compact disc cases. It is lightweight, rigid, versatile, and inexpensive, which makes it a popular choice for packaging and containers.
While polystyrene can be recycled, it is not always accepted by local recycling programs due to the challenges in managing it. It requires specialist recyclers, and even then, there is a preference for clean, white polystyrene without any tape, plastic film, labels, loose parts, or glued-on cardboard. The higher melting temperature of polystyrene also adds to the cost of the recycling process, making it less likely to be recycled.
The presence of a #6 symbol on a food container indicates that it is made of polystyrene. These containers are often white foam blocks, although they can also come in other colours. They are usually lightweight and rigid, making them convenient for storing and transporting food items.
It is important to note that plastic No. 6 or polystyrene is recommended to be avoided due to potential health risks. When plastic is improperly disposed of, it can end up deteriorating on land or in water, breaking down into smaller pieces that can contaminate our food and water sources. Additionally, when heated, polystyrene products can release potentially toxic breakdown products, such as styrene, into food or beverages.
