What You'll Learn
Polystyrene or Styrofoam
Plastic products are often stamped with a number, typically on the bottom, side, or top, ranging from 1 to 7. These numbers are resin identification codes that correspond to the type of plastic used in the container. Polystyrene or Styrofoam is indicated by the number 6.
Polystyrene, or Styrofoam, is used to make most disposable containers and foodware. It is also prevalent in packaging materials such as packing peanuts. This type of plastic is difficult to recycle and is considered harmful to health and the environment. Overwhelming evidence suggests that polystyrene leaches potentially toxic chemicals, especially when heated. It is best to avoid using polystyrene products, especially for food storage, and opt for glass or metal containers instead.
Polystyrene is lightweight, cheap to produce, and easily formed, which makes it a popular choice for various applications. However, its low density and high air content make it challenging and expensive to recycle. Polystyrene must be shipped to specialized facilities for compression, making it time-consuming and costly to transport over long distances.
Due to the widespread use of polystyrene, there has been a growing effort to create more facilities to recycle this material. Some municipalities now collect and reuse polystyrene, but it is still not accepted everywhere. It is important to check with local guidelines to understand the specific recycling protocols for this material.
To summarize, polystyrene or Styrofoam, identified by the number 6, is a plastic that should be used with caution. It is difficult to recycle and potentially harmful to health. It is essential to minimize the use of polystyrene products, especially around food, and opt for more environmentally friendly alternatives whenever possible.

Difficult to recycle
Plastic is everywhere, from food containers to packaging. Most plastic items have a recycling symbol on the bottom, top, or side, with a number from 1 to 7 inside. These numbers are called resin identification codes and indicate the type of plastic the item is made of. While some plastics are considered safe and can be recycled, others, like plastic #6, are difficult to recycle and should be used with caution, especially around food.
Plastic #6, also known as polystyrene or Styrofoam, is challenging to recycle. It is lightweight, cheap to produce, and easy to form, which has led to its widespread use. However, only specific recycling facilities accept this type of plastic. The difficulty in recycling #6 plastic arises from its low density, which makes it mostly air. As a result, it is costly and time-consuming to transport over long distances for recycling. To make it cost-effective, #6 plastic needs to be compressed at special facilities before being shipped, adding an extra step to the recycling process.
The health risks associated with #6 plastic also contribute to its classification as a difficult-to-recycle material. Studies suggest that polystyrene can leach potentially toxic chemicals, especially when heated. Long-term exposure to styrene, a chemical found in polystyrene, may affect the respiratory, nervous, and gastrointestinal systems. Due to these health concerns, it is recommended to avoid using #6 plastic, especially for food storage or preparation.
To minimize potential health risks and environmental impact, it is advisable to reduce plastic use, especially around food. Glass, metal, bamboo, and other reusable materials are safer alternatives. For plastic items that can be recycled, it is important to check your local municipality's guidelines, as some types of plastic may not be accepted in your recycling bin. Additionally, certain hard-to-recycle plastics, like Styrofoam, require specialized handling, and you may need to contact specific recycling companies that deal with such materials.

Avoid using for food storage
Plastic products are often stamped with a resin code, which is a number between one and seven inside a small triangle made of arrows. This number represents the type of plastic the product is made from. While some types of plastic are considered safe for food storage, others should be used with caution or avoided altogether.
Number 6 plastic stands for polystyrene (PS) or styrofoam, which should be avoided or, at least, reused as it is hard to recycle. Overwhelming evidence suggests that this type of plastic leaches potentially toxic chemicals, especially when heated. It is important to note that even plastics that are labelled ""microwave-safe" may not be safe for use in the microwave, as they may release harmful chemicals when heated. Therefore, it is best to avoid using number 6 plastic for food storage or preparation.
Plastics that are generally considered safe for food storage include those labelled with a 1, 2, 4, or 5. These plastics have no known health issues and are widely accepted for recycling. However, it is still recommended to minimise the use of plastic around food and to replace plastic containers with glass or other environmentally friendly alternatives whenever possible.
While recycling is important, it is worth noting that not all plastics are easily recyclable. For example, number 7 plastic includes new plastics, bioplastics, and items composed of different types of plastics, which can be difficult to recycle. Additionally, some municipalities may have specific guidelines for which types of plastic can be placed in recycling bins. Therefore, it is crucial to check with local guidelines before disposing of plastic items.
In summary, it is best to avoid using number 6 plastic for food storage due to its potential health risks and recyclability challenges. Instead, opt for glass, metal, bamboo, or other reusable and environmentally friendly alternatives. By making conscious choices about the types of materials we use, we can minimise our exposure to potentially harmful chemicals and reduce our environmental impact.

Potential health risks
Plastic products with the number 6 recycling logo are made of polystyrene (PS) or styrofoam. This type of plastic is hard to recycle and is known to cause potential health risks.
Polystyrene is lightweight, cheap to produce, and easily formed, making it a widely used material in packaging and insulation. However, its fragility leads to environmental concerns as it easily breaks up into tiny pieces that can be found on beaches and in marine creatures.
The potential health risks associated with polystyrene are primarily due to the leaching of styrene, especially when heated. Styrene is a toxic chemical that has been linked to carcinogenic effects. Insulated styrofoam cups, for example, can release styrene into hot beverages when heated.
To reduce exposure to potentially harmful chemicals, it is advisable to avoid using plastic containers marked with recycling code 6, especially for storing food and beverages, and when possible, switch to alternative materials such as glass, metal, or bamboo.
While recycling number 6 plastic is possible, it is not widely practiced, and most factories do not accept it due to the specialized handling required for styrofoam. However, there is a growing trend towards creating more facilities to recycle polystyrene due to its widespread presence in the environment.

Reuse and recycle
Number 6 plastic, also known as polystyrene (PS) or styrofoam, is widely applied to packaging and insulation. It is lightweight, cheap to produce, and easy to form. However, it is fragile and easily breaks up, leading to environmental contamination. Number 6 plastic also contains styrene, which can be leached when heated.
Due to these concerns, it is recommended to avoid number 6 plastic as much as possible. If you do come across this type of plastic, it is important to note that it is difficult to recycle and only accepted by specific recycling facilities. Some facilities are now accepting number 6 plastic due to its widespread presence in the environment, but it is still preferable to collect and reuse it.
To identify number 6 plastic, look for the recycling symbol, which is a triangle made of chasing arrows with the number 6 inside, usually found on the bottom, side, or top of the plastic object. This symbol is known as the resin identification code and provides information about the type of plastic and its recyclability.
- Reuse: Instead of discarding number 6 plastic items, try to reuse them as much as possible. For example, if you have a styrofoam cooler, consider using it for multiple picnics or outings instead of throwing it away after a single use.
- Check Local Recycling Guidelines: Contact your local recycling facility or check their website to find out if they accept number 6 plastic for recycling. Some facilities now specialize in recycling this type of plastic.
- Separate and Clean: If your local facility accepts number 6 plastic, separate it from other recyclables and give it a quick rinse or wipe to remove any food residue. This helps prevent contamination of other recyclables during the recycling process.
- Collect and Donate: If you are unable to reuse number 6 plastic items yourself, consider collecting and donating them to organizations or artists who may be able to repurpose them creatively.
- Choose Alternatives: Whenever possible, opt for alternative materials that are safer for your health and the environment, such as glass, metal, or bamboo. For example, instead of buying disposable styrofoam cups, invest in reusable glass or metal cups.
