Plastic waste is a major environmental problem, and it is essential that we all play our part in reducing it. While recycling plastic is an important step in the right direction, not all plastics are created equal, and not all types are recyclable. Some non-recyclable plastics, such as thin plastic items, can clog the processing machinery at recycling facilities, and it is better to dispose of them in the general waste. However, this is not ideal as it will still end up in landfills, causing harm to the environment. To avoid this, individuals can focus on reducing their plastic consumption, reusing plastics, and properly sorting their waste. Additionally, scientists are working on innovative solutions, such as implementing plastic-eating enzymes, to address the issue of non-recyclable plastics.

Reduce plastic consumption
Plastic waste is a major environmental problem, and it is essential that we all play our part in reducing it. While recycling plastic correctly is a step in the right direction, it is not always possible to recycle plastic items, and they often end up in landfills or oceans, causing harm to marine life.
- Avoid single-use plastics: Single-use plastics, such as plastic bags, straws, and disposable water bottles, are a significant source of plastic waste. Instead, opt for reusable alternatives like cloth napkins, reusable shopping bags, and a reusable water bottle.
- Reduce waste: Focus on reducing waste by choosing products with minimal packaging. Buy items in bulk or larger containers instead of several smaller ones over time. Purchase products packaged without plastic, such as unpackaged fruits and vegetables, or those wrapped in paper.
- Reuse and repurpose: Instead of discarding unwanted plastic items that are still in good condition, consider selling or donating them. Reuse items such as containers, water bottles, and bags.
- Buy recycled: When possible, purchase products made from recycled plastic materials. This helps to reduce the demand for new plastic production and gives recycled plastic a new lease of life.
- Support plastic-free businesses: Choose to dine at restaurants that have partnered with campaigns to reduce plastic waste, such as the 'Let's Shedd Plastic' initiative. These restaurants often use compostable or reusable utensils, to-go containers, and cups, helping to reduce single-use plastic waste.
- Advocate for change: Contact your local policymakers and advocate for legislation that encourages plastic reduction. Support initiatives and campaigns that aim to reduce plastic consumption and raise awareness about the issue.

Reuse non-recyclable plastics
While recycling plastic is beneficial to the environment, not all plastics are recyclable. Some common non-recyclable plastics include cling film, plastic bags, plastic wrapping, plastic straws, plastic medication bottles, and styrofoam food containers.
Non-recyclable plastics can be reused in several ways. For example, plastic bags can be reused multiple times before disposal. Animal shelters may also accept empty prescription bottles for donation, reusing them for animal medications.
Additionally, some non-recyclable plastics can be melted and reformed into new items. For instance, many drink bottles, LEGO blocks, and other products can be recycled in this way. These plastics are labelled with a 1 or 2, indicating their resin type.
Research is also underway to develop new processes for recycling challenging types of plastics. One such process involves converting fixed crosslinks in certain plastics into dynamic, changeable ones, creating a new type of recyclable plastic called vitrimers.
It is important to consult with local recycling centers, as some may have the technological capability to recycle specific plastic codes that are generally considered non-recyclable. For example, some recycling centers can transform plastic codes #3, #6, and #7 into useful items like egg cartons, vents, and cables.
Until more sustainable solutions are widely available, it is essential to be proactive in reducing plastic consumption and opting for reusable and recyclable alternatives whenever possible.

Dispose of non-recyclable plastics in general waste
Plastic waste is a significant environmental problem, and it is crucial that we all play our part in reducing it. While recycling plastic is an important step, not all plastics can be recycled. Some common non-recyclable plastics include plastic bags, plastic film, snack wrappers, cellophane, coffee bags, and prepared food pouches. These items are often made with multiple types of materials or plastic resins that cannot be easily separated, so they should be disposed of in the general waste.
It is important to note that even recyclable plastics can end up in landfills if they are not properly sorted and cleaned before recycling. For example, food packaging that is not properly cleaned may be deemed contaminated and rejected by recycling facilities, ultimately ending up in landfills. To avoid this, make sure to only recycle clean and sanitised packaging. Additionally, some plastics, such as thin plastic film, flexible packaging, and snack bar wrappers, are not accepted by many recycling programs because they can jam up machinery.
To properly dispose of non-recyclable plastics, it is recommended to throw them away in your general waste bin. While this may seem uneconomical, it is better than putting them in the recycling bin, where they can cause more harm than good. These non-recyclable plastics can clog the processing machinery at recycling facilities, interfering with the recycling process.
However, there are alternative options for disposing of non-recyclable plastics. Some local grocery stores and retailers have in-store drop-off bins specifically for these types of plastics. These bins are taken to special facilities equipped to recycle thin plastics and turn them into new products. Additionally, some local recycling centers may have programs in place to recycle clean, non-curbside plastics. It is worth calling your local recycling center to inquire about their programs and keep the demand high for such initiatives.
To reduce your plastic consumption, you can opt for products packaged without plastic or choose reusable alternatives. For example, instead of using single-use plastic water bottles, you can switch to a reusable water bottle made from eco-friendly materials. You can also compost your food scraps, soiled paper, and yard waste instead of sending them to landfills. By being mindful of our plastic consumption and disposal, we can all play a part in reducing plastic waste and its impact on the environment.

Avoid contaminating other recyclables
The improper disposal of non-recyclable plastic can contaminate other recyclables and lead to all items being rejected and sent to landfills. To avoid contaminating other recyclables, it is important to separate and properly dispose of non-recyclable items. Here are some ways to do this:
Firstly, it is crucial to understand what items are non-recyclable. This includes plastic food trays, carryout containers, disposable cups, straws, and Styrofoam takeout boxes, which are contaminated with food and made from low-value plastic resins. Prescription bottles, medication bottles, and plastic tubes from toothpaste or lotion are also non-recyclable due to their small size and traces of medication or product residue. Plastic hazardous substance containers, such as automotive fluid bottles, and any plastic used for personal hygiene or medical purposes should be disposed of in the trash as they contain hazardous substances.
Secondly, when it comes to recyclable plastics, ensure they are clean and dry before placing them in the recycling bin. Food residue, oil, and grease can contaminate other recyclables and render them unfit for recycling. Rinse or scrape off any food residue from containers, and make sure they are "spatula-clean" before recycling. Additionally, check with your local recycling guidelines to understand what specific types of plastic they accept.
Thirdly, reduce your plastic consumption by opting for reusable alternatives. Plastic water bottles, for example, contribute significantly to global plastic waste. Instead, opt for a reusable water bottle made from eco-friendly materials. Over 20,000 businesses in the UK operate as "Refill Stations", allowing you to refill your water bottle when out and about.
Lastly, some plastic items, such as plastic bags, plastic wraps, and plastic shipping packaging, are not accepted by most curbside recycling bins but can be recycled at participating retail stores. Always check with your local recycling entity to understand their specific guidelines and ensure proper disposal.

Use waste-to-energy systems
The current plastic waste management system is inadequate, with only 10% of plastic waste being recycled globally, 50% ending up in landfills, 22% being mismanaged, and 19% incinerated. This has led to the accumulation of plastic waste in the environment, causing significant environmental problems.
Waste-to-energy (W2E) systems offer a potential solution to this issue by converting non-recyclable plastic waste into a dense energy source. W2E technologies, such as pyrolysis and gasification, can be used to convert difficult-to-recycle plastic waste into energy. For example, the Maldives has committed to transforming a waste lagoon, where plastic waste was burned or leaked into the ocean, into a large-scale "plastics-to-energy" facility. This initiative will establish a modern waste collection, transfer, and disposal system across the nation.
While W2E systems provide a potential solution to the plastic waste problem, it is important to address the critical gap in current research: the emission of CO2 during these processes. To make W2E methods more sustainable, the focus should be on emergent CO2 capture and utilization technologies. By implementing these solutions, we can unleash the potential of using waste plastics as a dense energy source while mitigating the environmental impact of plastic waste.
In addition to W2E systems, chemical recycling technologies are also being developed to transform previously unrecyclable plastic waste into new plastics. For example, Plastic Energy's patented process involves heating plastics in the absence of oxygen to form hydrocarbon vapours, which are then condensed into a recycled feedstock called TACOIL™. This process diverts plastic waste from landfills and incineration, reducing the environmental impact of plastic waste.
To reduce our reliance on non-recyclable plastics and the need for disposal, it is essential to opt for products packaged without plastic and use reusable alternatives whenever possible. Broken glass and oil-stained items, such as pizza boxes, can contaminate recyclable materials, leading to entire loads being rejected by recycling facilities. Therefore, it is crucial to only recycle clean and sanitised packaging to avoid contributing to landfill waste.
