Plastic utensils are theoretically recyclable, but several issues prevent local programs from accepting them. Plastic utensils are made from polystyrene, PET, or polypropylene, and are often mixed with other types of plastic, making it challenging to separate and recycle them. They also have irregular shapes and are lightweight, making it difficult for automated machinery to sort them effectively. Additionally, only a few municipalities accept plastic utensils for recycling, and companies often find it cheaper to dispose of them as waste. As a result, most plastic utensils end up in landfills, contributing to the environmental problem of plastic waste. To address this issue, individuals can opt for reusable utensils, compostable alternatives, or look for local recycling programs that accept specific types of plastic utensils.

What You'll Learn
Plastic utensils are recyclable but rarely recycled
Plastic utensils are, theoretically, recyclable. However, they rarely make it to the recycling process and end up in landfills or incinerators instead. This is due to several reasons, including the fact that they are often not accepted by local recycling programs and the challenges of sorting and processing them.
Most plastic utensils are made of polystyrene, a type of plastic commonly recognized as Styrofoam. Polystyrene is highly recyclable and can be reprocessed multiple times. However, plastic utensils often consist of multiple types of plastics with different melting points and densities, making it challenging to separate and recycle them effectively. Additionally, their irregular shape and lightweight nature make it difficult for automated machinery to sort them, requiring costly manual labor.
Another challenge is that plastic utensils are not collected in most cities' curbside recycling programs. Only a few municipalities have decided to accept them, and even if they are collected, they might end up being exported to other countries, like China, which has recently cracked down on plastic imports. This creates a significant obstacle to the recycling of plastic utensils.
Furthermore, it is often easier and cheaper for companies and individuals to dispose of plastic utensils as garbage rather than going through the effort and expense of recycling them. This contributes to the low recycling rate of plastic utensils, despite their technical recyclability.
To address this issue, it is recommended to move away from plastic utensils and opt for reusable or compostable alternatives. Reusable metal utensils are a more sustainable option, reducing the environmental impact of single-use plastics. Some sources suggest reusing plastic utensils multiple times before disposal, but this has limitations, especially in commercial settings where hygiene standards must be maintained.

They are made from polystyrene, PET, or polypropylene
Plastic utensils are typically made from polystyrene, PET, or polypropylene. Polystyrene is a highly recyclable material that can be reprocessed multiple times. It is the most common material used for plastic utensils, also being used to make Styrofoam. However, polystyrene utensils are often mixed with other plastics at recycling centres, making it challenging to separate and reuse them.
PET, or polyethylene terephthalate, is another type of plastic used for utensils. It is identified as #1 plastic and has a larger recycling market than polystyrene. Polypropylene, or #5 plastic, is the third common type of plastic used for utensils. It is the most recyclable of the three, accepted by most curbside recycling programs.
Despite being made of recyclable materials, plastic utensils often end up in landfills or incinerators. This is due to several factors. Firstly, plastic utensils are not uniform, being made of multiple plastics with different melting points and densities, making them difficult to recycle. Secondly, their irregular shape and lightweight nature make it challenging for automated machinery to sort them, requiring costly manual labour. Additionally, only a few municipalities accept plastic utensils for recycling, as it is often cheaper for companies to dispose of them as waste.
To address these issues, individuals can take several steps. Reusing plastic utensils multiple times before disposal can reduce waste. Additionally, opting for reusable metal utensils or compostable fibre-based utensils is a more sustainable alternative.

They are not collected in most cities' recycling programs
Plastic utensils are not collected in most city recycling programs, and even if they are, they often don't make it into the recycling stream. This is due to several reasons, including the fact that they are not made of one uniform material but of multiple types of plastics with different melting points and densities. Some plastic spoons, for example, may contain more than one type of plastic, making it difficult to recycle them as the different types of plastics need to be sorted before they can be processed.
Another issue is that plastic utensils are typically not labelled with a plastic resin number, so it is difficult to know which type of plastic you are dealing with unless you have the original packaging. If your local recycling program does not specifically say it accepts all plastics or a specific type of plastic, it is best to leave plastic utensils out of the recycling bin. This is because they can jam machinery in materials recovery facilities (MRFs) and are often considered a top source of contamination.
The irregular shape and lightweight nature of plastic utensils compared to other materials like paper or glass also make them difficult to sort with automated machinery. They often fall through sorting screens, requiring manual labour to remove them from the recycling stream and sort them into the proper bin for processing. This can be time-consuming and costly, and as a result, many recycling programs choose not to accept plastic utensils.
Furthermore, it is often easier and cheaper for companies to simply throw plastic utensils away rather than recycle them. This is because recycling plastic utensils can be complex and not cost-effective, especially considering the low value of recycled plastic. As a result, plastic utensils often end up in landfills or incinerators instead of being recycled, contributing to the vast amount of plastic waste that exists today.

They are classified as rigid plastics
Plastic utensils are not always recycled, even though they are made of polystyrene, a highly recyclable material. This is due to several factors, including the fact that they are often mixed with other types of plastic, making it difficult to separate the polystyrene for recycling. Additionally, plastic utensils are lightweight and irregularly shaped, causing them to fall through sorting screens and jam machinery in materials recovery facilities (MRFs). They are classified as rigid plastics, similar to clamshell packaging, blister packs, and yogurt containers.
The classification of plastic utensils as rigid plastics is significant because it affects their recyclability. Rigid plastics are those that maintain their shape and do not collapse easily, which can make them more challenging to recycle than flexible plastics. This rigidity contributes to the challenges associated with sorting and processing plastic utensils. Their shape and size can cause them to fall through sorting screens, and their rigidity can make them more likely to jam machinery.
Another challenge with recycling plastic utensils is that they are often not accepted by local recycling programs. Many curbside recycling programs do not include plastic utensils, and even if they are accepted, they might be sorted out and sent to landfills or incinerators due to the challenges and costs associated with processing them. This issue varies depending on the location, with only a few municipalities accepting plastic utensils for recycling.
To address the issue of recyclability, some people choose to reuse their plastic utensils multiple times before disposing of them. Others opt for more sustainable alternatives, such as reusable metal utensils or compostable fiber-based utensils. It is worth noting that while plant-based cutlery is marketed as compostable, there are doubts about whether these products actually break down completely, even under high temperatures.
In summary, while plastic utensils are classified as rigid plastics, their recyclability is limited due to challenges in the recycling process and the lack of acceptance by many local recycling programs. To reduce the environmental impact of plastic utensils, it is recommended to prioritize reusable or compostable alternatives whenever possible.

Reusing them yourself is an option
Reusing plastic utensils yourself is an option. You can rinse and reuse them until they break, then dispose of them in the garbage. Some sources suggest that plastic utensils can be reused for about a week before they start to take on the smell and discolour.
If you have a large number of plastic utensils, you could consider donating them to a local food bank or homeless shelter. Many shelters serve food on disposable plates and utensils, and they will have to purchase them if they are not donated.
You could also try to sneak some of your used plastic cutlery into a drop-off at your local shipping store, as they may take back and reuse #6 plastic, which is the type of plastic used for utensils. However, they may not allow you to continue to recycle there if they notice.
If you are looking to be more environmentally friendly, it is best to avoid buying plastic utensils altogether and instead opt for reusable utensils.
