Plastic is everywhere, and it's cheap to make and profitable. However, only about 9% of the world's plastic has been recycled, with the rest causing devastation to our seas, communities, and ecosystems. Non-recyclable plastics include those contaminated with food or dirt, hazardous substances, or low-value plastic resins. These plastics often end up in landfills, where they can escape the dumping site and cause further environmental damage. To address plastic pollution, producers need to be held accountable for the damage their products cause, and we need to develop more recyclable products and sustainable alternatives.

What You'll Learn
Plastic waste is shipped to poorer nations
Plastic waste is often shipped to poorer nations, despite global efforts to curb this practice. In 2021, more than 180 nations agreed to place strict limits on exports of plastic waste from richer countries to less wealthy ones. However, trade data from the same year indicates that American exports of plastic scrap to poorer nations have barely changed, and overall scrap plastics exports have increased. This suggests that exporters are ignoring the new rules and relying on a remarkable interpretation of them. According to the amended Basel Convention, exporters must obtain consent from the governments of receiving nations before shipping contaminated, mixed, or unrecyclable plastic waste.
The United States, a major exporter of plastic waste, is not a party to the Basel Convention. This means that the new regulations could effectively prevent the US from selling contaminated or mixed plastic waste to developing nations. Despite this, American companies continue to export plastic waste overseas, often to poorer countries. For instance, in 2015, China and Hong Kong handled more than half of the 9% of America's plastic that was estimated to have been recycled that year. However, much of the plastic waste exported to China was contaminated with food or dirt, or it was non-recyclable and ended up in Chinese landfills.
In response to growing environmental and health concerns, China shut its doors to all but the cleanest plastics in 2017. This caused a significant shift in the global plastic waste trade, with Southeast Asian nations such as Thailand, Malaysia, Vietnam, and Indonesia becoming overwhelmed with shipments of waste they lacked the capacity to handle. As a result, several countries took action to stop shipments at their ports, leading to plastic trash pileups in places like San Francisco, the UK, and other European nations.
While the majority of the world's plastic waste is handled domestically, the trade in plastic waste has significant environmental and social impacts. Low-to-middle-income countries, where plastic waste is at a higher risk of entering the ocean due to poorer waste management systems, imported around 1.6 million tonnes of plastic waste from rich countries in 2020. This trade in plastic waste contributes to the existing waste management challenges in these countries and can have detrimental effects on the environment and the health of local communities.

Plastic is incinerated, creating harmful gases
Plastic is cheap to make and profitable, but it is also everywhere, causing damage to the environment. About 91% of plastic is not recycled, and only about 9% of the world's plastic has been recycled. The remaining plastic waste ends up in our seas, causing devastation to our communities, environment, and ecosystems.
One of the issues with non-recyclable plastic is that it often ends up in landfills. However, even a well-managed landfill poses threats to our ecosystem. During the decomposition process of plastic and other solid waste, a highly toxic liquid called leachate is formed. Leachate can leak into the environment during rainfall and contaminate our soil and groundwater.
Another issue with non-recyclable plastic is that it is often incinerated. Incineration creates notable contributions to GHG emissions and deteriorates air quality. In countries where the price of electricity is high, it might be more profitable to incinerate plastic waste instead of recycling it.
PVC, which is often used to make pipes and other materials, breaks down into toxic chlorine-containing components and cannot be recycled. One possible replacement for PVC is PHA, or polyhydroxyalkanoate, a type of bio-polyester made by bacterial fermentation of sugars and lipids. However, it is difficult to produce more sustainable plastics, and most biodegradable and compostable plastics on the market only biodegrade in industrial reactors.

Plastic is sorted by resin type
Plastic is everywhere, and it is cheap to produce and profitable. However, it is also a major source of pollution. While recycling is one way to address the problem, not all plastics are recyclable. Non-recyclable plastics are often sent to landfills or shipped overseas, contributing to environmental and health concerns.
Sorting plastics for recycling is essential, and it starts with identifying the resin type. Plastic resins are the backbone of the plastics industry, and they come in various types, each with unique properties and applications. One of the most common ways to identify the resin type is through the resin identification code, which consists of a number surrounded by a triangle of arrows. These codes help consumers and recyclers alike identify the type of plastic and its recyclability.
Polyethylene terephthalate, commonly known as PET, is one of the most widely used plastic resins. It is often found in beverage and food containers, such as soft drink bottles, and even some beer bottles. PET is also used in the textile industry to create permanent-press fabrics. When it comes to recycling, PET is highly valued as it falls under recycling code "1", making it easy to collect, sort, and recycle. It can be transformed into new products like fibres for clothing or carpets.
Another common plastic resin is polyvinyl chloride (PVC). PVC is versatile and used in a wide range of applications, from pipes to everyday household items. It comes in two main types: flexible and rigid. Flexible PVC is used in cables, hoses, and flooring, while rigid PVC is found in window frames, pipes, and building siding. Despite its versatility, PVC cannot be recycled as it breaks down into toxic chlorine-containing components.
Other plastic resins include polyethylene, polypropylene, polyvinyl chloride, and polystyrene. These resins are used in a variety of applications, from food packaging to automotive components. However, not all of these resins are easily recyclable, and some, like polystyrene, are considered low-value plastic resins.
The process of sorting plastics for industrial recycling requires vigilance. Recycling companies rely on their providers to correctly sort the plastics before sending them for recycling. Mixing certain types of plastics can lead to dangerous chemical reactions, as in the case of combining PET and PVC, which can result in the release of harmful acids or toxic dioxin emissions. Therefore, providing detailed specifications of the plastic materials to the recycler is crucial to ensure safe and efficient recycling.

Plastic with food residue is non-recyclable
Plastic is a cheap and profitable material that is used everywhere. However, it is a key concern for environmentalists, governments, and organizations as it can take hundreds of years to biodegrade, leading to polluted oceans, overextended landfills, and ecological damage. While recycling plastic is critical to improving the environment and bettering waste management solutions, only about 9% of plastic is recycled globally.
The issue of non-recyclable plastic with food residue is not limited to a single country or region. For example, in the United States, it was found that much of the plastic waste being exported to other countries was contaminated with food or non-recyclable. Similarly, in developing nations such as Vietnam and the Philippines, the influx of plastic waste from developed countries has become a significant problem, with local recycling industries struggling to keep up.
To address the problem of non-recyclable plastic with food residue, it is important to reduce plastic consumption and improve recycling practices. This includes developing better, more recyclable products, finding sustainable alternatives, and increasing circularity by keeping products in use for as long as possible. Additionally, proper waste segregation and disposal methods are crucial to ensure that non-recyclable plastics do not end up in landfills or incinerators, further contributing to environmental pollution.
While recycling is an important part of the solution, it is not the only answer to the plastic pollution crisis. Other alternatives, such as biodegradable and compostable plastics, are being explored, but they come with their own set of challenges. For instance, most biodegradable plastics currently on the market only biodegrade in industrial reactors, and many are not less toxic than conventional plastics. Therefore, a multi-pronged approach that includes reducing plastic consumption, improving recycling technologies, and developing truly sustainable alternatives is necessary to tackle the complex issue of non-recyclable plastic with food residue.

Plastic is recycled mechanically or chemically
Plastic is everywhere, and it is cheap to make and profitable. However, it has a significant negative environmental impact. To address plastic pollution, producers need to pay for the damage it causes, and the world will also have to make less plastic. A circular economy requires both mechanical and chemical recycling.
Mechanical recycling is the dominant method, representing more than 99% of the infrastructure and business. It involves shredding and melting plastic waste to create plastic pellets, which can be formed into new products. However, it is expensive, and the recycled plastic is costly compared to virgin plastic. It also does not produce a clean product, and there are limitations in finding clients for mechanically recycled plastic.
Chemical recycling, on the other hand, splits the polymer chains of plastic and can provide crude oil, naphtha, or fuels. It can produce virgin-like plastic feedstock, enabling "re-cycling" and "up-cycling". It can also remove impurities, making it suitable for food-contact packaging. Chemical recycling can make plastic infinitely recyclable, whereas mechanical recycling can only recycle plastic between 3 to 7 times.
However, chemical recycling is not yet proven to work on a large industrial scale, and it requires toxic chemicals and more energy, producing more CO2 emissions. It is also expensive, with a chemical recycling plant costing around €200 million to build.
Both methods have their advantages and disadvantages, and a combination of the two is likely needed to create a circular economy for plastics.
