What You'll Learn
Polystyrene foam (Styrofoam) is not recyclable in your blue bin
Polystyrene foam, commonly known by the trademarked term Styrofoam, is not suitable for your blue bin. This is due to its lightweight and bulky nature, which makes it difficult to process using standard recycling systems. While Styrofoam does technically contain recyclable elements, it is comprised of more than 90% air, making it inefficient to collect and transport for recycling.
The lightweight nature of Styrofoam means it is easily carried by the wind, and its propensity to burst into tiny plastic pieces means it can contaminate other recyclables during the recycling process. As a result, it is often banned from standard recycling centres, and must be taken to a specialist location for recycling.
Despite the chasing arrows recycling symbol on Styrofoam products, those foam egg cartons, meat trays, and packaging peanuts are not recyclable in your blue bin. However, there are some locations that do recycle Styrofoam. Some local governments and recycling companies have drop-off locations specifically for foam packaging, and the EPS industry has developed collection facilities to support global recycling efforts.
To recycle Styrofoam, it must be densified. This involves grinding, melting, and compressing the material into dense blocks, which can then be sold to other manufacturers for reprocessing. The reprocessed Styrofoam can be used to create new products such as coat hangers, picture frames, and building materials.
To reduce your environmental impact, it is best to avoid using Styrofoam products where possible. You can bring your own reusable containers for takeaway food and coffee, purchase meat from a butcher that doesn't use Styrofoam trays, and opt for cardboard packaging when buying home appliances.

EPS foam is 98% air and 2% plastic
Plastic foam packaging, such as Expanded Polystyrene (EPS) foam, is recyclable. However, it is not easy to recycle and often ends up in landfills. EPS foam, for instance, is composed of 98% air and only 2% plastic. This composition makes EPS highly versatile, lightweight, and an excellent cushion for products, protecting them from damage during transit. However, the same composition also makes EPS bulky and challenging to recycle using standard systems.
The lightweight and bulky nature of EPS foam makes it difficult to process in standard recycling systems. Specialized equipment is required to compress and densify the material before it can be reused or recycled. The high air content in EPS, which gives it its desirable properties for packaging, also makes it occupy a lot of space, increasing transportation costs and logistical challenges.
Despite these challenges, EPS foam can be successfully recycled and repurposed. The EPS industry has developed collection facilities to support global recycling efforts. The recycling process involves feeding the foam into grinders, compressing it into dense blocks, and sometimes melting it into a paste. This densified EPS is then sold to manufacturers for reprocessing into new products, such as picture frames, coat hangers, and building materials.
Although EPS foam is technically recyclable, the infrastructure for recycling is not always readily available. The low density and high volume of EPS mean that it is often not cost-effective for recycling programs to collect and process it. As a result, many areas do not accept EPS for curbside recycling. However, some specialized facilities can handle EPS recycling, and the recycled material can be used to create new products.
Overall, while EPS foam is technically recyclable, the challenges of its lightweight and bulky nature, as well as the lack of widespread recycling infrastructure, contribute to low recycling rates. Improving recycling technologies and increasing support for specialized recycling facilities are crucial steps towards enhancing the recyclability of EPS foam and reducing its environmental impact.

Polyethylene foam is 100% recyclable but requires specialist facilities
Plastic foam packaging is not easy to recycle. It is lightweight and bulky, making it difficult to process using standard recycling systems. Most plastic materials, including foam, are derived from fossil fuels like gas and oil, and will not break down in landfills. In fact, the Sierra Club reports that only about 6% of the foam used for consumer packaging is recycled, with the overall rate, including industrial foam recycling, being just 12%.
However, polyethylene foam is 100% recyclable but requires specialist facilities. Polyethylene is a type of plastic material with a variety of uses, including in mattress film and foam fabricating material. Polyethylene foam is used in protective packaging, especially in the automotive industry, due to its flexibility and shock-absorbing properties.
To recycle polyethylene foam, it must first be condensed, or densified, to reduce its volume and make transportation more efficient. This can be done using a compacting machine, or by melting the foam into a paste. The densified foam can then be sold to other manufacturers for reprocessing. Reprocessing involves grinding, melting, and cutting the foam into pellets, which can then be used to make new products such as coat hangers, picture frames, and building materials.
There are a limited number of companies that specialise in polyethylene foam recycling, including GREENMAX and Generated Materials Recovery (GMR). These companies offer various services, such as providing equipment for recycling and transportation, and creating personalised recycling solutions for businesses.

Plastic bags are not recyclable in your blue bin
Plastic foam packaging and plastic bags are both items that cannot be placed in your blue bin for recycling. However, this does not mean that they cannot be recycled at all.
Firstly, plastic bags should never be placed in blue or yellow recycling bins. They can damage recycling equipment and are very harmful to the environment. It is best to avoid using them and instead use reusable bags. However, if you do have plastic bags, you can drop them off at a recycling center or take them to a local grocer.
Secondly, plastic foam packaging can be recycled, but it is not that simple. The three main types of foam used in packaging—expanded polystyrene (EPS) foam, polyethylene (PE) foam, and polyurethane (PU) foam—can be recycled. However, they require specialized facilities to be processed correctly. The foam is bulky and lightweight, making it difficult to transport and store, and it cannot be mixed with other types of foam. As a result, many areas do not accept foam for curbside recycling, and it often ends up in landfills.
To recycle plastic foam packaging, you can contact the Alliance of Foam Packaging Recyclers or explore custom solutions offered by companies like SmartShield. Additionally, some manufacturers use recycled foam packaging, so there are opportunities to support sustainable practices in the industry.
In summary, while plastic bags should be avoided and reused whenever possible, and plastic foam packaging can be recycled through specialized facilities or manufacturers, neither of these items should be placed in your blue bin for recycling.

Plastic foam is lightweight and bulky, making it difficult to recycle
Plastic foam is widely used in the packaging industry because it is lightweight and offers great cushioning and stability. However, its lightweight and bulky nature also makes it difficult to recycle.
Firstly, plastic foam is challenging to recycle because it is too lightweight to be processed by standard sorting machines. This means that it can contaminate other recyclables during the recycling process. Additionally, plastic foam contains a high percentage of air, making it bulky and costly to transport. For example, Expanded Polystyrene (EPS) foam is approximately 95-98% air and only 2-5% plastic. This composition makes it cheap and highly versatile for packaging purposes, but it also means that it takes up a lot of space, making transportation inefficient and expensive.
Secondly, there is a lack of infrastructure to recycle plastic foam effectively. Specialized equipment is required to densify plastic foam materials before they can be sent back to manufacturers for reuse. However, there are limited relationships between regional recycling programs and foam manufacturers due to the low volume of each material type. The variety of foam types also creates challenges, as they cannot be mixed in recycling streams. Therefore, separating and determining the correct recycling pathway for each piece of foam is a complex and inefficient process.
Despite these challenges, it is important to note that plastic foam can be recycled, and advancements in recycling systems are improving the efficiency of foam recycling. For example, some recyclers have developed collection facilities to support global EPS foam recycling efforts. These facilities use grinders to cut the foam into smaller pieces, which are then compressed into dense blocks. The densified EPS is sold to manufacturers for reprocessing into new products, such as coat hangers, picture frames, and building materials.
To promote sustainability, manufacturers using foam packaging can partner with companies like New-Tech Packaging, which offers custom-fit foam packaging made from recycled content. By working with specialized recyclers and adopting reusable packaging solutions, we can reduce the environmental impact of plastic foam packaging.
