The types of plastics that can be recycled vary depending on your location. In California, for example, there is a ban on single-use plastic bags, and the state offers refunds for returned beverage containers. In Oregon, plastic bags can be recycled but not at the curb, and plastic bottles that have contained hazardous materials like pesticides or motor oil cannot be recycled. The most widely recycled plastic in the world is PET, which is found in plastic bottles and can be recycled into fashion items, like polar fleece clothing, backpacks, and carpets. However, it's important to note that not all plastics are accepted by community recycling programs, and some plastics are more difficult to recycle than others due to the cost and technical challenges of separating different types of plastics.

What are the recycling procedures for different plastics?
Recycling is a complex process that involves multiple steps and organisations to ensure that plastic is transformed into new products. The recycling process can be broadly categorised into three types: mechanical recycling, chemical recycling, and energy recycling.
Mechanical recycling is the most common form of plastic recycling worldwide. It involves collecting and separating recyclable materials from waste, processing them into raw materials, and then using them to create new products. This process can be repeated for the same application, such as with glass, but some materials like plastic will degrade in quality over time, leading to "cascade recycling". For example, a PET bottle can be recycled into a plastic film, which can then be downcycled into clothing material. While mechanical recycling can give plastic a second or third life, the quality will eventually deteriorate to the point where it cannot be recycled further.
Chemical recycling is a newer technology that aims to address the limitations of mechanical recycling by breaking down plastics into their raw, high-quality materials. One method is pyrolysis, which involves heating polymers in the absence of oxygen, causing them to behave like synthetic oil. This oil can then be used as feedstock in the petrochemical industry for creating new plastics, synthetic rubber, and chemicals. Another chemical recycling process is gasification.
Energy recycling is a method that specifically targets plastic waste, converting it into thermal and electric energy through incineration. This approach is popular in densely populated areas where landfill space is limited, such as in Europe and Japan. While energy recycling used to be controversial due to emissions concerns, stricter regulations and the use of catalyzers have made it more environmentally friendly.
Regardless of the recycling method, the process typically begins with collection. Plastic waste can be collected through kerbside collection services, where local authorities or waste management contractors pick up household recycling bins on a weekly or bi-weekly schedule. Alternatively, individuals can drop off their recyclable materials at community recycling centres or smaller sites in communal areas like supermarket car parks. These centres may also accept larger items, electrical waste, and non-packaging plastics.
Once collected, the plastic waste is transported to Material Recovery Facilities (MRFs) or Plastic Recovery Facilities (PRFs). These facilities use optical sorters and, in some cases, robotic arms to separate plastic from non-plastic materials and sort them into different types of plastic. The sorted plastic is then baled and sold to reclaimers, who process the material into recycled plastic. Finally, the recycled plastic is used to create new products, completing the recycling journey.

What types of plastic are not recycled in your area?
The types of plastic that can be recycled vary depending on your location. It's important to check with your local recycling program to find out which types of plastic they accept.
In general, some types of plastic that may not be accepted by community recycling programs include:
- Plastic bags: They are recyclable, but not at the curb. Plastic bags can tangle in recycling machinery, risking endangering the entire recycling process. Many municipalities won't accept plastic bags in curbside recycling bins.
- Plastic with food residue: Containers contaminated with food scraps or residue often cannot be recycled. This includes items like pizza boxes, which can be recycled if food scraps are removed and they are flattened.
- Compostable plastic: Compostable plastics are not intended for recycling and can contaminate the recycling stream if mixed with non-compostable plastics.
- Biobased plastic: The recyclability of biobased plastics depends on the product's label and the waste disposal options available in your area.
- Plastic with multiple types of plastic or layers: Items made from different types of plastic or layers that cannot be easily separated may not be recyclable.
- Plastic number 3 (polyvinyl chloride): This type of plastic is not recyclable in normal collections.
- Plastic lids: Lids are often too small or flat to be sorted out during the recycling process and can end up contaminating other materials, such as paper.
- Plastic trays and containers from microwaveable meals, deli products, and prepackaged meals: These containers, if not round, are often not accepted for recycling.
It's worth noting that even if a plastic item can be recycled, it doesn't always mean it will be. For example, low-density polyethylene (LDPE), used for plastic bags, is technically recyclable, but many municipalities don't accept it due to the challenges and costs associated with recycling it.

What are the environmental impacts of non-recyclable plastics?
The environmental impacts of non-recyclable plastics are far-reaching and have serious consequences for both human and ecological health. Plastic pollution is pervasive, with microplastics and nanoplastics found in every ecosystem on the planet, from the Antarctic tundra to tropical coral reefs. The issue is that plastic takes a long time to decompose, with estimates ranging from 100 to 1000 years or more, depending on the environment. This means that plastic waste will continue to accumulate in landfills and natural habitats, causing problems for wildlife and humans alike.
One of the most significant concerns is the ingestion of plastics by marine species, which can lead to suffocation or entanglement. Research indicates that over 1500 species in marine and terrestrial environments are known to ingest plastics. In addition, chemicals from plastic products can leach into tap water, potentially causing developmental, reproductive, neurological, and immune disorders. Microplastics have even been found in human livers, kidneys, and placentas, although more research is needed to understand the full impact on human health.
The production of new plastics also contributes to environmental issues. Measures to reduce the production of plastics from oil and the reuse of plastic packing crates can help to reduce the environmental impact of plastic production. Recycling is another solution, as it significantly reduces fossil fuel utilisation, power consumption, and landfilling. However, global recycling rates are currently low, at only 9%, and there are barriers to effective plastic recycling, such as the complexity of plastic products and the market forces that make virgin plastics cheaper than recycled alternatives.
Furthermore, the use of plastic is expected to triple by 2060 compared to 2019, which will only exacerbate the problem. While recycling rates may double during this period, there is still a significant risk of environmental leakage. This includes the presence of non-biodegradable plastics in the environment, which can have catastrophic consequences. To address the issue of plastic waste, a combination of solutions is needed, including reducing plastic production and consumption, improving waste disposal and material handling, and increasing recycling capacity and efficiency.

How do resin codes help identify recyclable plastics?
The Resin Identification Code (RIC) is a technical standard with a set of symbols that appear on plastic products. These symbols identify the plastic resin used to make the product. The RIC system was designed to make it easier for workers in recycling facilities to sort and separate items according to their resin type.
The RIC consists of a number (1-7) inside a triangle, which is often mistaken for the universal recycling symbol. The numbers 1-6 mean that the plastic packaging is made from one of six specific types of plastic: 1 means polyethylene terephthalate (such as PET plastic bottles), 2 means high-density polyethylene (HDPE), 3 means polyvinyl chloride (PVC), 4 means low-density polyethylene (LDPE), 5 means polypropylene (PP), and 6 means polystyrene. The number 7 means the packaging is made of a type of plastic other than the previous six, or is a mixture of plastics.
The presence of a RIC on an item does not necessarily indicate that it is recyclable, and the absence of an RIC does not mean that the plastic object is not recyclable. However, the RIC can help consumers decipher if a product is recyclable and choose between different packaging options. For example, HDPE is widely recycled and reused in recycled plastic bottles, so by paying attention to the RIC and checking what plastics can be recycled locally, consumers can ensure they are recycling as much plastic as possible.
In addition to the RIC, other symbols such as the How2Recycle labels encourage consumers to check with local facilities to see what plastics can be accepted for recycling.

What are the best practices for recycling plastic in your area?
While almost all plastic can be recycled in principle, there are a variety of barriers that can undermine this process. These include the presence of multiple types of plastic and different layers within a single item, which are difficult and costly to separate.
To recycle plastic effectively in your area, it is important to be aware of the specific practices and guidelines in place. Here are some best practices to follow:
- Know your local guidelines: Different areas may have different guidelines for plastic recycling. Check with your local recycling facility or website to understand what types of plastic they accept and how they prefer it to be handled. For example, some areas may prefer plastic bottles to be flattened.
- Sort and separate plastics: If your local recycling center requires you to separate different types of plastic, follow their guidelines for placing them in the appropriate recycling bins. Keep plastic bottles, jugs, and jars separate from other plastics.
- Clean your recyclables: Rinse bottles and caps before recycling, especially if they contain any liquid residue. This helps maintain the quality of the recycled material and prevents contamination.
- Handle plastic bags properly: Plastic bags can cause issues in recycling machinery, so they should not be placed in curbside recycling bins. Instead, take them back to stores or drop them off at recycling centers that collect them separately.
- Recycle plastic bottles: Plastic bottles are widely recycled and play a vital role in the circular economy. They can be transformed into new bottles or even fashion items like T-shirts and backpacks.
- Consider drop-off locations: Some plastic materials that cannot be recycled at home may be accepted at specific drop-off locations or recycling businesses.
- Support local initiatives: Local governments and organizations often work together to address plastic pollution through regulatory interventions, educational campaigns, and partnerships. Support and participate in these initiatives to help reduce plastic waste.
- Encourage innovation: Advocate for the development and expansion of innovative systems to ensure plastic products are reused as long as possible. This includes finding new ways to design products for easier reuse.
By following these best practices and staying informed about your local guidelines, you can contribute to more efficient plastic recycling in your area and support a more sustainable future.

Frequently asked questions
The types of plastics that are recycled depend on your local municipality's guidelines and your local recycling center's capabilities. Contact your local recycling center to know which plastics they collect. Generally, most recycling centers accept plastics #1 and #2. Plastics #3 to #6 are harder to recycle, and some centers do not process them. Plastic #7 is the most challenging to recycle and is almost always excluded.
Plastic #1, or PET, is used for water bottles, plastic soda bottles, shampoo bottles, detergent containers, and oil bottles. Plastic #2, or HDPE, is used for milk jugs, rigid and soft plastic forms, and plastic bags.
Plastic #3, or PVC, is used for building materials such as pipes, fittings, and hoses. Plastic #4, or LDPE, is used for grocery bags. Plastic #5, or PP, is used for food containers, medicine bottles, and rope. Plastic #6, or PS, is used for disposable plates, cups, and carry-out containers.
Plastic #7 is a catch-all category for other types of plastics, including polyamide (nylon), polycarbonate, acrylonitrile butadiene styrene, and thermoplastic elastomers.
It depends on the type of plastic and your local guidelines. Some plastics, such as grocery bags, can clog recycling machinery if not separated properly and are therefore not accepted by kerbside collections. Other plastics may be difficult to recycle but may not be explicitly excluded from your recycling bin. Always check with your local guidelines and sorting facilities to ensure you are recycling correctly.
