Plastic pollution is a pressing issue, with plastic waste found in oceans, snow, and even human blood
Plastic pollution is a pressing issue that affects the environment and human health. While recycling is often touted as a solution, the sad reality is that only 9% of plastic waste is recycled globally, with the rest persisting in the environment as waste that breaks down into microplastics. These microplastics, smaller than 5mm in diameter, are pervasive and have been found in oceans, snow, and even human blood.
In oceans, microplastics are a significant contributor to marine pollution. They mimic fish eggs and other tiny organisms, leading to their consumption by marine life. Once ingested, microplastics are nearly impossible to filter out, becoming a permanent fixture in the ecosystem. The vastness of the ocean, covering nearly three-fourths of the Earth, underscores the magnitude of the problem. It is central to life on our planet, providing more than half of the world's oxygen and supporting economic activities. Yet, it is choking on plastic waste.
The presence of microplastics in snow further highlights the extent of plastic pollution. Recent studies have detected microplastics in snow samples from Antarctica, indicating long-range transportation of up to 6000 km. Local sources, such as plastic equipment from research stations and clothing, also contribute to plastic pollution in this pristine environment. The Antarctic Treaty Consultative Meeting in 2019 emphasized the need to eliminate products containing microplastic beads and improve wastewater treatment to address this issue.
Perhaps most alarmingly, microplastics have been found in human blood. A pioneering study identified polymers from plastics in the blood of healthy volunteers, indicating the bioavailability of plastic particles for uptake into the human bloodstream. While the health implications are not yet fully understood, the presence of plastic particles in human blood underscores the urgency of addressing plastic pollution.
To effectively tackle this pressing issue, a multifaceted approach is necessary. This includes reducing plastic production and consumption, redesigning products and packaging to use less plastic or facilitate reuse, and improving recycling practices. Collaboration between governments, industries, scientists, and consumers is crucial to implement these solutions and mitigate the impact of plastic pollution on our oceans, environment, and human health.

Recycling plastic is challenging due to the variety of plastic types, and most end up in landfills
Plastic is everywhere, and humans have created around 11 billion metric tons of it. This amount surpasses the biomass of all animals on Earth, both on land and in the sea. The plastic crisis is worsening, and the industry plans to triple plastic production by 2050.
Recycling plastic is challenging due to the variety of plastic types. There are now thousands of different types of plastic, and none of them can be melted down together. The process of mechanical recycling, where plastic waste is collected, cleaned, sorted, shredded, melted, and formed into pellets, is straightforward in theory but difficult in practice. Different types of plastic do not mix well when melted down, and small amounts of the wrong type can degrade the quality of a whole batch. As a result, plastic must be carefully sorted, usually with the help of high-tech machines at large-scale recycling facilities. However, even with diligent sorting, recycled plastic is almost always of lower quality than primary plastic. This is because the long polymer chains that make up these materials become slightly shorter each time they are melted down, and the various combinations of additives used to give plastics different colours and technical properties result in recycled material with unpredictable and often suboptimal additive combinations.
The vast majority of plastic that people use ends up in landfills. A Greenpeace report found that people may be putting plastic into recycling bins, but almost none of it is actually being recycled. For instance, while 52% of recycling facilities in the US accept plastic cups and containers, less than 5% of this plastic is actually repurposed. Similarly, the National Association for PET Container Resources found that only 21% of the plastic bottles collected for recycling in 2017 were turned into new products. This issue is further exacerbated by the fact that plastic is cheap and easy to produce, making plastic trash less marketable.
The use of recycled plastic is not a solution to the global plastic crisis. A 50% recycled plastic bottle, for instance, does not address the issue of where the plastic goes after being used and discarded. It is still just as likely to end up in the ocean to be eaten by marine animals. Furthermore, advertisements for products with recycled plastic perpetuate the myth of plastic recycling as an efficient and reliable process, which is far from the truth. Instead, the focus should be on eliminating and reducing the demand for single-use plastic and replacing it with reusable and refillable alternatives.

Some countries have high recycling rates, but others, like the US and China, lag
While some countries have high recycling rates, others, like the US and China, lag. The recycling rate in the US is controlled at the state level, and it can be challenging to estimate the total amount of waste recycled. The US produced an estimated 3 million tons of plastic packaging in 2017, and about 95% of tap water in the country is contaminated with microplastics. A Greenpeace report revealed that most plastic ends up in landfills, and plastic production is increasing. The problem is exacerbated by the high cost of collecting and sorting plastic, with thousands of different types that cannot be melted down together.
In contrast, Austria, another European country, has a high recycling rate of approximately 54%. This is due to strict legislation banning certain products from landfills. South Korea, an Asian country, also has a high recycling rate of 53.7%, with successful private companies collecting, recycling, and selling waste for profit. China has been revamping its recycling system, pressuring other countries like South Korea to improve their recycling rates.
The low recycling rates in some countries, like the US, can be attributed to a lack of federal regulations and the high cost of collecting and sorting plastic. Additionally, companies often engage in greenwashing, misleading consumers by making their products appear more eco-friendly than they are. For example, a 50% recycled plastic bottle is not a solution to the global plastic crisis and does not address the issue of single-use plastic. To solve the pollution crisis, certain plastics, such as polyvinyl chloride (PVC), must be eliminated and replaced with sustainable alternatives.
To improve recycling rates and address the plastic waste crisis, countries like the US and China need to implement stricter regulations and focus on reducing the demand for single-use plastic. Additionally, companies should be transparent with their customers and make genuine efforts to minimize environmental damage, rather than engaging in greenwashing.

Recycled plastic has many uses, from fashion to construction, but it's often expensive
Plastic is everywhere, and the world is paying the price. Plastic production is ramping up, and despite efforts to recycle, most plastic ends up in landfills. The problem is that plastic is challenging to recycle, and it is expensive to collect and sort. There are thousands of different types of plastic, and they cannot be melted down together.
However, recycled plastic does have many uses, from fashion to construction. Recycled PET (polyethylene terephthalate) plastic, for instance, has a market for use in strapping or polyester fabrics, as well as in packaging. Recycled PE and PP plastics are also used for packaging, though less frequently for food items due to difficulties in achieving the required level of cleanliness. Recycled plastics are also used in concrete, where they can replace conventional aggregates to reduce the overall bulk density of the concrete.
The use of recycled plastic in these applications helps to create market demand for recycled materials, supporting the collection and processing of recycled plastics. However, recycling plastic is often more expensive than using new plastic. This is due to several factors, including the high cost of collecting, sorting, and recycling the plastic, as well as the low market value of the recycled material. For instance, a study in Japan found that businesses paid $376 million in recycling fees for containers and packaging recycling from 2012 to 2020.
To address the issue of plastic waste, manufacturers are under pressure to use more recycled plastic in their products. For example, Coca-Cola's European business plans to cut the amount of virgin plastic used in its soft drink bottles to 50% within a two-year period. The UK also plans to tax companies that don't use at least 30% recycled plastic in their products.

Companies like ADS are increasing their use of recycled plastics, investing in technology
The use of recycled plastics is a pressing issue, with human-made plastic now surpassing the biomass of all animals on the planet. Companies like ADS are taking steps to address this by increasing their use of recycled plastics and investing in new technology.
In 2024, ADS, one of the largest plastics recycling companies in North America, increased its share of recycled materials to 50% of its total resin purchases. This is a significant increase from 48% in 2023 and 45% in 2022. To achieve this, ADS approved $36 million in capital expenditures for its recycling operations in 2024, including replacing older pelletizers, increasing capacity, and upgrading facilities and equipment to improve resin quality. The company also increased its overall capital spending by 10% to $184 million, with a focus on increasing automation, manufacturing growth, and recycling capacity.
Other companies are also investing in recycled plastics and new technologies. For example, 3R Technology California is opening its first U.S. location in Southern California, where it will process e-plastics into clean, separated flakes for the U.S. market. Phoenix, Arizona-based Supersede is another company that uses recycled plastic to create a plywood-alternative board specifically for marine use.
Initiatives like the Circular Plastics Fund are also helping to drive change, with billions of dollars invested in plastic recycling over the last few years. Dow, LyondellBasell, and NOVA Chemicals have contributed an initial $25 million to this fund, which aims to attract up to $100 million from businesses. The fund will invest in scalable recycling technologies, equipment upgrades, and infrastructure solutions to improve and increase plastic recycling.
While these efforts are commendable, it is important to note that simply increasing the use of recycled plastics may not be enough to solve the global plastic crisis. As Inger Andersen, executive director of UNEP, pointed out, we also need to redesign products to use less plastic and be more easily reused or recycled. Additionally, as Imari Walker-Franklin, a research chemist, noted, we need to eliminate and replace "unnecessary and problematic" plastics, such as polyvinyl chloride (PVC), with more sustainable alternatives.

Frequently asked questions
It's a start, but there is still a long way to go. While 50% recycled plastic is better than none, the reality is that plastic production is increasing, and the amount being recycled is not keeping up. In fact, a Greenpeace report found that most plastic ends up in landfills, and the plastic that is recycled is often down-cycled into products that cannot be recycled again.
PET (Polyethylene Terephthalate) is the most widely recycled plastic globally. It is relatively easy to recycle, and it is used to make products like bottles, fashion items, carpets, and even construction materials in some countries.
There are several challenges to recycling plastic. Firstly, there are thousands of different types of plastic, and they cannot be melted down together. Sorting and collecting plastic is also expensive, and many communities do not have the infrastructure to effectively recycle plastic. Additionally, some types of plastic, like PVC, break down into toxic components and cannot be recycled at all.
To improve plastic recycling rates, we need systemic change. This includes redesigning products to use less plastic and be more easily recycled, replacing unnecessary plastics with sustainable alternatives, and investing in recycling infrastructure. Individuals can also contribute by reducing their plastic consumption, properly disposing of plastic waste, and supporting companies that use recycled materials.
