Plastic waste is a pressing environmental concern, with plastic taking hundreds of years to biodegrade and leading to issues such as polluted oceans, overflowing landfills, and ecological damage. While recycling plastic is critical to improving the environment and waste management, not all plastics are created equal when it comes to recyclability. Some plastics are widely recycled, while others, such as non-recyclable plastic, pose a challenge. Non-recyclable plastic refers to plastic types that cannot be easily recycled due to factors like the manufacturing process, the presence of hazardous substances, or contamination with food. These plastics often end up in landfills or oceans, causing harm to the environment and marine life. However, there is ongoing research and new processes being developed to recycle challenging plastic types, offering hope for a more sustainable future.

What You'll Learn
Identify non-recyclable plastics
Plastics are typically labelled with numbers 1–7 to indicate their resin type and recyclability. These numbers are known as Resin Identification Codes. Plastics labelled with numbers 3, 6, and 7 are generally non-recyclable and are considered the most toxic. Number 3 plastics, or polyvinyl chloride (PVC), are found in single-use plastic wraps, window cleaner and detergent bottles, shower curtains, vinyl piping, flooring, and home siding. Number 6 plastics, or polystyrene (PS), are typically in the form of Styrofoam cups, plates, and containers. Number 7 plastics are a catch-all category and may contain hazardous byproducts like BPA and BPS. They can include plastic baby bottles, water jugs, sunglasses, medical storage containers, plastic cutlery, and toys.
Other non-recyclable plastics include bioplastics, composite plastic, plastic-coated wrapping paper, and polycarbonate. Cling film, blister packaging, and thin plastic bags or films are also usually non-recyclable due to the risk of clogging recycling machinery. Some common items made from non-recyclable plastics include crisp wrappers, snack wrappers, cellophane, coffee bags, prepared food pouches, plastic cutlery, disposable cups, and medication bottles.
It is important to note that the recyclability of plastic can vary depending on the capabilities of the recycling centre and local guidelines. For example, some recycling centres may be able to recycle plastics labelled as number 3, 6, or 7. Additionally, certain plastics may be recyclable in some areas but not in others, so it is always good to check with your local council or recycling provider.
To identify non-recyclable plastics, look for the Resin Identification Code on the bottom of the plastic item. If it is labelled with numbers 3, 6, or 7, it is likely non-recyclable. However, it is still good to double-check with your local recycling guidelines or provider to ensure proper disposal.

Reuse non-recyclable plastics
While it is important to recycle plastic where possible, not all plastics are created equal, and some are more easily recycled than others. Non-recyclable plastics include bioplastics, composite plastic, plastic-coated wrapping paper, polycarbonate, and thin bags or films. These items are often non-recyclable because they are made with multiple types of materials or plastic resins that cannot be separated.
However, there are ways to reuse non-recyclable plastics to divert them from landfills. One way is to check with your local recycling centre, as some centres have the technological capability to recycle certain non-recyclable plastics. For example, some recycling centres can transform non-recyclable plastics into useful items like egg cartons, vents, speed bumps, cables, and panelling.
Another option is to explore alternative, eco-friendly disposal methods such as those listed in The Waste Hierarchy. Additionally, some organisations offer nationwide recycling programs for typically hard-to-recycle waste streams. For example, TerraCycle offers free recycling programs for items like contact lenses, makeup products, e-waste, oral care products, and cigarette waste. These items are then turned into raw materials and sold back to factories to create new products.
While it is important to first reduce our consumption of single-use plastics, it is also possible to reuse some non-recyclable plastic items before disposing of them. For example, plastic bags can be reused multiple times before disposal. Additionally, some animal shelters accept empty prescription bottles for animal medications.

Recycle non-recyclable plastics via specialist programmes
Recycling non-recyclable plastics is a challenging task, but some specialist programmes and initiatives offer innovative solutions to treat these materials. One such example is TerraCycle, a company that provides free nationwide recycling programs for hard-to-recycle waste streams. They accept a wide range of items, from contact lenses to electronic waste, and even cigarette waste. The process involves individuals signing up for specific product programs, sending in their waste, and allowing TerraCycle to transform it into raw materials that can be sold back to factories for new product creation. This approach not only reduces landfill waste but also encourages the reuse of materials.
Another approach to dealing with non-recyclable plastics is through waste management providers and government initiatives. Many organisations and governments have adopted a zero-waste-to-landfill policy, promoting alternative, eco-friendly disposal methods. For instance, some countries in Europe, such as Germany, Austria, and Norway, are collecting and recycling rigid packaging like trays, tubs, and pots, as well as flexible packaging like films and wrappers. This expansion of recyclable materials is made possible by advancements in sorting and washing technologies.
In addition to collection programs, there are also mechanical and chemical recycling methods. Mechanical recycling involves washing, grinding, and melting plastic waste, while chemical recycling breaks down plastic into monomers to form new polymers for reuse. These processes are constantly evolving, leading to the inclusion of more plastic types in recycling streams over time.
It's worth noting that some non-recyclable plastics, like bioplastics, composite plastic, plastic-coated wrapping paper, and polycarbonate, pose challenges due to their irreversible chemical bonds. However, organisations like SL Recycling are dedicated to diverting waste from landfills and offer comprehensive recycling services for various materials, including plastic, wood, and metal. They emphasise the importance of proper waste management and provide guidance on what can and cannot be recycled.
While recycling non-recyclable plastics can be difficult, these specialist programmes and initiatives offer innovative solutions. By participating in local collection programs, utilising mechanical or chemical recycling methods, and supporting organisations dedicated to reducing landfill waste, we can collectively improve our environmental impact and find new uses for these challenging materials.

Recycle non-recyclable plastics by converting them into a different type of plastic
The majority of plastics can be recycled and reused, but some types of plastic are non-recyclable. These include bioplastics, composite plastic, plastic-coated paper, and polycarbonate. Non-recyclable plastics often end up in landfills or oceans, leading to ecological damage and polluted oceans.
However, new processes are being developed to recycle non-recyclable plastics by converting them into a different type of plastic. For example, researchers at Case Western Reserve University have developed a method to recycle non-recyclable thermoset plastics. Thermoset plastics contain polymers with irreversible chemical bonds, making them difficult to recycle. The new process involves combining thermoset plastic with a zinc-based compound and grinding it into a fine powder using a ball mill. This powder can be pressed into a heated mold and reformed into a new shape. This new type of plastic can be reheated and remolded without the need for additional zinc compound. This process has the potential to reduce the amount of plastic waste in landfills and improve waste management solutions.
Another approach to recycling non-recyclable plastics is through chemical recycling. This process involves breaking down plastic into monomers to form new polymers that can be reused. Chemical recycling allows for the creation of new plastic products with different properties, such as improved strength or flexibility.
Additionally, some recycling centers have the technological capability to recycle specific types of non-recyclable plastics, such as #3, #6, and #7. These plastics can be transformed into useful items like egg cartons, vents, speed bumps, cables, and paneling. It is always worth checking with local recycling centers to see if they have the capacity to recycle certain types of non-recyclable plastics.
Overall, while non-recyclable plastics pose a significant environmental challenge, ongoing research and advancements in recycling technologies offer promising solutions. By converting non-recyclable plastics into different types of plastic, we can reduce waste, conserve resources, and contribute to a more sustainable future.

Avoid products packaged in non-recyclable plastics
Plastic waste is a key concern for environmentalists, governments, and organizations, as the majority of plastics are disposed of in non-environmentally friendly ways. This results in polluted oceans, overfilled landfills, and ecological damage.
Recycling plastic is critical to improving the environment and bettering waste management solutions. Recycling any material, where possible, is fundamental to the environment, and recycling plastic has specific benefits. Plastic can take hundreds of years to biodegrade, between 500-1000 years for some types, meaning it takes up landfill space and pollutes the environment for longer. Recycling plastic can conserve limited natural resources and energy. As plastic is made from oil, the more plastic that is recycled and the less that is made from raw materials, the more oil is conserved.
The difference in the recyclability of plastic types can be due to how they are made; thermoset plastics contain polymers that form irreversible chemical bonds and cannot be recycled, whereas thermoplastics can be re-melted and re-molded. Examples of non-recyclable plastics include bioplastics, composite plastic, plastic-coated wrapping paper, and polycarbonate. Well-known non-recyclable plastics include cling film and blister packaging.
To avoid products packaged in non-recyclable plastics, look for products that use recyclable, compostable, or recycled packaging. Avoid products with flashy packaging that could easily be avoided, or cheap goods that fuel more consumerism. Bring your own containers or bags when shopping, and opt for products in glass or metal packaging. Support companies that are taking the initiative and experimenting with designs that reduce waste or utilize reusable or compostable components.
You can also take action by talking to the owners of the restaurants you frequent and asking if they have non-plastic alternatives to plastic straws, stirrers, or bags. Let companies know that you care about their packaging by contacting them via social media, phone, or email. Support local plastic bans and policies that encourage corporate responsibility for waste, such as bottle bill laws, which require retailers to add a fee to individual bottles that can be partially refunded when recycled.
