Plastic trays are a common household item, often used for takeout, store-bought products, or hard plastic food trays. With approximately 300,000 tonnes of plastic pots, tubs, and trays sold in the UK in 2017, it is important to recycle them properly. The recyclability of plastic trays varies depending on the region, with some areas accepting all plastics in the recycling bin, while others only recycle specific types of plastics. It is important to check with local guidelines to ensure proper disposal. Some plastics, such as thin plastics, small plastics, and plastic wrap, are generally harder to recycle and may be considered unrecyclable in certain locations. Additionally, it is recommended to reduce the use of single-use packaging and opt for biodegradable or compostable alternatives whenever possible.

What You'll Learn
Plastic tray recycling varies across different locations
Different types of plastic require different recycling processes, which means that various facilities are needed. Some plastics are harder to recycle, such as small plastics (bottle caps), plastic wrap, and plastic bags. These items can be melted down, but they are often considered unrecyclable due to the difficulty in sorting them.
The type of plastic is also a factor, with 1s and 2s being the most common and easily recycled, while 3s, 5s, and 7s are less likely to be accepted. 4s and 6s fall in the middle, being recyclable in some areas but not in others. Plant-based plastic trays, for example, are rarely recyclable as they need to be separated from other plastics. However, plant-based paper or cardboard trays are usually compostable.
Location also matters when it comes to recycling guidelines. When traveling or moving, it is essential to check the local guidelines. Some areas have online tools to help residents determine what can be recycled, and local councils' websites often provide detailed information. Additionally, some businesses accept plastic film for recycling, and these can usually be found in stores' entryways.

Some plastics are harder to recycle than others
Most plastic trays can be recycled as part of household recycling schemes. However, it's important to note that some plastics are harder to recycle than others due to various factors. Firstly, it depends on the type of plastic and local council rules. Many councils accept most plastic trays as part of their household recycling schemes, but some do not accept thin plastic trays or black plastic trays.
Thin plastics, like those used for bacon packaging, are often non-recyclable and can cause microplastics. Thicker plastics, on the other hand, are more widely recycled. Black plastic trays are challenging to recycle because they are difficult to sort using the automated systems in recycling plants due to their colour. Black trays are typically sorted manually, which is a more time-consuming process. Therefore, it's recommended to check your local council's guidelines to understand their specific capabilities and restrictions regarding plastic tray recycling.
Laminated pouches, such as pet food or coffee pouches, are another type of plastic that is particularly difficult to recycle. These pouches have a tendency to spring back when you try to scrunch them, and they are currently not recyclable in most areas. As a result, they should be disposed of in the general waste bin.
To make recycling plastic trays easier, it is suggested to separate any recyclable parts, such as cardboard or paper sleeves, and recycle them separately. Additionally, ensure that any food residue is removed from the trays before placing them in the recycling bin, as leftover food can contaminate other recyclables.
Lastly, while recycling is crucial, it's even more important to reduce our overall plastic consumption. Plastic is inherently challenging to recycle because it often consists of multiple materials, like plastic, paper, and adhesives, which are difficult to separate during the recycling process. Therefore, to effectively address the plastic waste crisis, it's essential to minimise the use of single-use plastics and opt for reusable alternatives as much as possible.
In summary, while most plastic trays can be recycled through household recycling schemes, certain types, such as thin or black plastic trays, may pose challenges depending on your local council's capabilities and regulations. By staying informed about the accepted plastics in your area and properly separating and preparing our recyclables, we can increase the likelihood of successful recycling and contribute to a more sustainable future.

How to recycle plant-based plastic trays
Plastic packaging, including trays, can be recycled as part of household recycling schemes, although this varies across different regions. It's important to recycle plastic trays, as around 300,000 tonnes of plastic pots, tubs, and trays were sold in the UK in 2017.
When it comes to plant-based plastic trays, there are a few things to keep in mind to ensure proper recycling:
- Check with your local council or recycling guidelines: Different regions have varying acceptance criteria for plastic trays. Some areas may accept plant-based plastic trays in their household recycling schemes, while others may require you to take them to specific drop-off points or recycling centres.
- Rinse the trays: Before recycling, use leftover washing-up water to rinse your plant-based plastic trays. Remove any leftover food residue, as it can contaminate other recyclables.
- Separate different materials: Separate any cardboard or paper sleeves from the plant-based plastic trays, as these can often be recycled separately.
- Remove plastic film and absorbent pads: While labels and lids can usually be left on, make sure to remove any plastic film and absorbent pads and dispose of them in your waste bin.
- Consider reusing or repurposing: Before recycling, consider whether you can reuse or repurpose the plant-based plastic trays. For example, gardeners can use sturdy plant-based plastic trays for seed starting multiple times before recycling them.
Additionally, some retailers, such as Home Depot and Lowe's, accept plastic plant pots and trays for recycling. However, this may vary by branch, so it's advisable to call ahead and confirm before heading to the store.

What to do with non-recyclable plastic trays
Plastic trays, tubs, and pots are accepted as part of household recycling schemes. However, this varies across different countries and local councils. For instance, in the UK, black plastic trays and laminated pouches are generally non-recyclable. Flower and plant pots also cannot be recycled at home but can sometimes be recycled at household waste recycling centres.
If you have non-recyclable plastic trays, here are some ways to deal with them:
- Check with your local recycling centre. Some recycling centres have the technological capability to recycle certain types of non-recyclable plastics, such as plastics displaying resin codes #3, #6, and #7. These plastics are typically non-recyclable because they are low-value plastic resins, but some centres can transform them into useful items like egg cartons, vents, and cables.
- Reuse them. For example, plastic trays can be used for craft projects or storing items such as paper clips and pencils. Schools and nurseries often collect plastic trays and tubs for this purpose.
- Find someone who can reuse them. For example, a keen gardener might be able to reuse plastic plant pots.
- Reduce your consumption of single-use plastics. This is the best way to ensure that non-recyclable plastics do not end up in landfills or the environment. Try to avoid products packaged in thin, non-recyclable plastics and opt for thicker plastics that are widely recycled instead.

How to identify different types of plastic trays
Identifying different types of plastic trays is important for consumers to make informed decisions about their usage and proper disposal, reducing plastic waste and contributing to a more sustainable future. Here are some ways to identify different types of plastic trays:
Resin Identification Codes (RICs)
Resin identification codes (RICs) are recycling symbols usually found on the bottom or side of plastic products. These codes are numbers from 1 to 7, each corresponding to a specific type of plastic resin. For example, "1" represents Polyethylene terephthalate (PET or PETE), a clear, strong, and lightweight plastic commonly used for beverage bottles and food containers. "2" stands for High-density Polyethylene (HDPE), a stiff, durable, and opaque plastic used for items like milk jugs, detergent bottles, and toys.
Floatation Test
A simple way to distinguish between broad groups of plastics is by determining whether they float or sink in water. Polyolefins, which include High-Density Polyethylene (2), Low-Density Polyethylene (4), and Polypropylene (5), generally float, while the rest tend to sink.
Physical Characteristics
The physical characteristics of plastic trays can also provide clues about their type. For instance, HDPE often feels harder and more crinkly, while LDPE produces a softer, swishing sound when manipulated. Polypropylene (PP) packets sound similar to HDPE but are stiffer and do not stretch, instead ripping or tearing when pulled.
Smoke Test
Applying a flame to a piece of plastic and observing the smoke and ignition can offer insights into its type. However, this method should be approached with caution due to the potential release of harmful fumes or chemicals. For example, Polyethylene Terephthalate (PET) produces a burnt sugar or candy floss-like odour, while Polyvinyl Chloride (PVC) emits an acrid, chlorine-like smell. Polypropylene (PP) smells like candle wax with a hint of paraffin, and ABS and Polystyrene resemble the scent of styrene, with ABS also carrying a faint rubbery note.
Usage and Properties
Identifying the intended use and unique properties of a plastic tray can also aid in determining its type. For example, plastic trays used in hospitals are designed for durability, ease of cleaning, and patient comfort. They are often lightweight, customizable, and cost-effective. Foodservice trays, such as those made of Acrylonitrile Butadiene Styrene (ABS), are known for their resistance to scratches, stains, and breakage, as well as their dishwasher safety. Melamine trays, another option for foodservice, offer durability, excellent stain resistance, and the ability to withstand a wide range of temperatures.

Frequently asked questions
The process of recycling a plastic tray depends on the type of plastic and your location. In general, plastic trays are accepted as part of household recycling schemes, but it is important to check your local council's guidelines. Some areas have different recycling facilities and may only recycle certain types of plastic. If your council does accept plastic trays, make sure to remove any plastic film and give the tray a quick rinse before placing it in the recycling bin.
The recyclability of a plastic tray depends on the type of plastic it is made from. Plastics are classified by resin codes, with #1 and #2 being the most commonly and easily recycled. Plant-based plastic trays may be biodegradable or compostable, but they often need to be recycled separately from other plastics. Disposable trays made from paper, cardboard, or other plant materials are typically biodegradable and can be recycled or composted if clean.
If you are unable to recycle plastic trays, there are a few alternatives to consider. You can donate them to schools or nurseries for craft projects or storage. Alternatively, look for biodegradable or compostable tray options made from plant-based materials, paper, or cardboard. These options are more environmentally friendly and can be recycled or composted properly.
