Plastic recycling is unprofitable and expensive
Plastic recycling is a complex and challenging process that is often unprofitable and expensive. While recycling plastic is essential for reducing environmental impact, there are several factors that make it unprofitable and costly.
Firstly, plastic is cheap to produce and highly profitable for manufacturers. This creates a disincentive to invest in recycling infrastructure and processes. The high profitability of new plastic production means that recycling plastic, which requires additional sorting, cleaning, and processing, becomes less economically attractive.
Secondly, the variety of plastic types poses a significant challenge. There are hundreds of different types of plastics, and they cannot be melted down together. This means that recycling facilities need to sort through and separate different types of plastics, which is a complex and labor-intensive task. The lack of standardization in plastic types and the difficulty of mixing them during recycling increase the cost and complexity of the process.
Additionally, the market for recycled plastic is fragmented, and it can be challenging to find buyers for recycled materials. The recycling infrastructure in many countries, particularly in the US and Europe, is inadequate. The closure of recycling programs and the lack of investment in new technologies further contribute to the issue. For example, China's ban on importing low-quality recyclables from America and Europe disrupted the global recycling market and led to an increase in waste being sent to landfills.
The degradation of plastic during the recycling process is another factor that affects profitability. Plastic degrades each time it is reused, limiting the number of times it can be recycled. This means that recycled plastic may not be as valuable as new plastic, reducing the economic incentive for recycling.
Lastly, the collection and transportation of plastic waste can be costly, especially in remote areas. The low value of waste plastic means that there is often no financial incentive for waste management services to collect and recycle it, particularly in low- and middle-income countries where formal recycling programs are rare.

Plastic is cheap to make and highly profitable
Plastic is cheap to produce and highly profitable. It is lightweight and therefore less energy-intensive to transport than other food and beverage packaging materials. This means that plastic products are found everywhere in the world, even in the most remote places.
The plastic industry is worth a staggering £250 billion globally. However, despite the vast amounts of plastic waste generated, there is little economic incentive to recycle it. This is because recycling plastic is expensive. There are hundreds of different types of plastic, and they cannot be melted down together. The process of picking up, sorting, and melting plastic is costly, and the resulting product degrades each time it is reused, meaning it can only be reused once or twice.
In contrast, new plastic is cheap to make and highly profitable. This means that, despite the environmental impact, it is often more cost-effective for companies to produce new plastic than to recycle old plastic.
The market for recycled plastic is also fragmented, making it difficult for sellers to find buyers. Recycling facilities are spread out unevenly, and in some areas, there is a lack of machinery to efficiently select and recycle plastic. This means that even when consumers put plastic in the recycling bin, it often ends up in landfills or incinerators.
The solution to the plastic waste crisis lies in reducing plastic production and increasing investment in recycling technologies. However, this is challenging due to the immense profits and political power of plastic producers.

Plastic waste is pervasive in low- and middle-income countries
Plastic waste is a significant issue in low- and middle-income countries due to various factors. Firstly, these countries often have inadequate waste management infrastructure, leading to higher rates of mismanaged waste. The lack of proper recycling facilities and effective domestic policies exacerbates the problem. As a result, plastic waste ends up in landfills or the environment, contributing to pollution and its associated environmental and socioeconomic impacts.
The true cost of dealing with plastic waste is significantly higher for low- and middle-income countries compared to richer nations. A report by WWF and global consulting firm Dalberg reveals that the lifetime cost of a kilogram of plastic for these countries is around $150, eight times higher than the $19 incurred by wealthier nations. This disparity is even more pronounced when comparing low-income countries alone, which face costs of $200 per kilogram, ten times higher than their richer counterparts.
The issue is further compounded by the overconsumption of plastic and the proliferation of single-use plastic products. Low-income communities, in particular, depend on affordable single-use plastic items, such as shampoo packets. While these products provide convenience and affordability, they contribute to the growing plastic waste problem. Additionally, the production and consumption of plastic are not adequately curbed, with plastic producers holding significant political power and economic influence.
To address plastic waste in low- and middle-income countries, a multifaceted approach is necessary. Firstly, investments in waste management infrastructure are crucial, with richer countries contributing through foreign investments. Domestic policies that improve waste management practices and promote recycling are also essential. Additionally, reducing the production and consumption of plastic, especially single-use plastics, is vital. This includes implementing regulations and transitioning towards reusable and refillable alternatives.
Furthermore, low- and middle-income countries often have minimal influence over the production and design of plastic products, yet they bear the burden of managing these products at the end of their life cycle. This highlights the need for global regulations and requirements to reduce plastic production and consumption, as advocated by organizations like WWF-US. The upcoming negotiations for the United Nations treaty on plastic waste in Nairobi, Kenya, presents an opportunity to establish transformative global regulations to tackle plastic pollution.

Most plastic ends up in landfills or the environment
Plastic is everywhere, and it is shockingly profitable. However, the vast majority of plastic ends up in landfills or the environment. According to a 2022 report from the Organisation for Economic Co-operation and Development, 72% of the plastic we make ends up in landfills or the environment, with only 9% of all plastic ever produced being recycled. In 2018, landfills in the United States received 27 million tons of plastic, which was 18.5% of all municipal solid waste (MSW) landfilled.
The problem is that recycling plastic is expensive and often doesn't make economic sense. There are too many different kinds of plastic, and they can't be melted down together. Plastic also degrades each time it is reused, meaning it can't be reused more than once or twice. As a result, most plastic ends up in landfills or is incinerated.
The environmental impact of plastic waste is significant. Plastic waste that is not properly managed ends up polluting the environment and entering our oceans, affecting wildlife and ecosystems. Microplastics, pieces of plastic smaller than five millimeters in diameter, have been found in the ocean, snow and rainfall, the air, and even in human blood, colons, lungs, veins, breast milk, placentas, and fetuses. It is estimated that the average person consumes five grams of plastic every week, mostly from water.
To address this issue, some countries are implementing extended producer responsibility (EPR) plans, which require producers of plastic bottles and packaging to provide funding to support the management of these materials after their initial use. Additionally, environmentalists and lawmakers in some states are pushing for legislation that bans single-use plastics and promotes systems of reuse and refill.

Oil companies misled the public about recycling
Oil companies have long been accused of misleading the public about recycling. Despite knowing that recycling plastic was not economically or technically feasible, they promoted it to sell more plastic and avoid regulation. An investigation by NPR and PBS Frontline revealed that the oil and gas industry used the promise of recycling to increase their plastic sales, even though they knew it would not work on a large scale.
The industry launched feel-good projects, telling the public to recycle plastic, and funded sorting machines, recycling centers, and nonprofits. However, few of these projects actually turned plastic into new products. For example, Mobil's Massachusetts recycling facility only lasted three years, and Amoco's project to recycle plastic in New York schools lasted just two years.
The Society of the Plastics Industry, a trade group, told producers in 1956 to focus on "low cost, big volume" and "expendability." They knew that if they focused on single-use plastics, people would continue to buy more. This led to the creation of the Plastics Recycling Foundation in 1984, which brought together petrochemical companies and bottlers and launched a campaign focused on the sector's commitment to recycling. In 1988, they introduced the "chasing arrows" symbol for recyclable plastic. Experts have long criticized this symbol as highly misleading.
The oil and gas industry has also been accused of greenwashing, where companies present themselves as environmentally responsible even though their practices may not be. For instance, they may promote recycling while continuing to produce new plastic, which is cheaper and more profitable. This has led to a global plastic waste crisis, with most plastic ending up in landfills or the environment.
While industry representatives deny intentionally misleading the public, the evidence suggests that oil companies have prioritized profits over environmental responsibility, contributing to the plastic waste crisis.

Frequently asked questions
Plastic is cheap to make and profitable, and it's everywhere. However, it's challenging to recycle. Plastic degrades each time it is reused, meaning it can't be reused more than once or twice. There are also too many different kinds of plastic, and they can't be melted down together. Plastic with food residues also usually cannot be recycled.
Most of the plastic we make ends up in landfills or the environment. Plastic that isn't recycled or reused doesn't chemically degrade but breaks apart to form microplastics, which have been found in oceans, snow, rainfall, the air, and even in human blood, colons, lungs, veins, breast milk, placentas, and fetuses.
Researchers are working to develop chemicals called compatibilizers, which help different types of plastic to mix together evenly when melted down. Efforts are also being made to improve sorting to ensure a purer, more uniform stream of plastic entering the recycling process.
