The Alarming Rise Of Plastic Waste: A Global Concern

Plastic waste is a pressing global issue. In the last 70 years, the annual production of plastics has increased nearly 230-fold to 460 million tonnes in 2019. The world produces around 350 million tonnes of plastic waste each year, with between 1 and 2 million tonnes entering the oceans annually. Rich countries produce the most plastic waste per person, but it is the mismanagement of waste in low-to-middle-income countries that is most concerning. This is because these countries tend to have poorer waste management infrastructure, leading to plastic waste leaking into the environment.

Rich countries produce the most plastic waste per person

Plastic waste has increased dramatically over the last 70 years, with annual production increasing nearly 230-fold to 460 million tonnes in 2019. The world produces around 350 million tonnes of plastic waste each year, with between 1 and 2 million tonnes of plastic entering the oceans annually.

Rich countries tend to produce the most plastic waste per person. In a study published in Science Advances, researchers found that residents of the US and the UK produce more plastic waste per person than any other nation, with Americans generating an average of 105kg (231lbs) of plastic per year. The British are close behind, throwing away almost 99kg (218lbs) annually. South Korea and Germany take the respective third and fourth spots in the top 10 countries ranked by plastic trash per capita. However, it is important to note that while high-income countries generate high amounts of plastic waste per person, they are also typically better at processing it safely.

In contrast, middle-income and low-income countries with less developed waste management infrastructure tend to produce a higher percentage of mismanaged waste plastic, which is more likely to end up in the ocean. A 2017 study found that 80% of mismanaged plastic in the ocean came from just five Asian countries: China, Thailand, Vietnam, Indonesia, and the Philippines. China, despite being the top producer of plastic for the global market, has a relatively low per capita plastic usage of just 15kg per person.

The issue of plastic waste is not just a matter of production but also of proper waste management. While rich countries may produce more plastic waste per person, the impact of this waste is mitigated by effective waste management systems. However, the export of plastic waste from rich countries to developing nations, as seen in the case of Malaysia, can overwhelm the waste management capabilities of these countries and contribute to the global plastic pollution crisis.

Mismanaged waste tends to be much higher in low-to-middle-income countries

Plastic waste has increased dramatically since the 1950s, with annual production increasing nearly 230-fold to 460 million tonnes in 2019. The world produces around 350 million tonnes of plastic waste each year, with between 1 and 2 million tonnes entering the oceans annually. This means that 0.5% of plastic waste ends up in the ocean, and around one-quarter of plastic waste is mismanaged. Mismanaged waste refers to plastic that is not recycled, incinerated, or stored in sealed landfills, and is therefore at risk of leaking into the environment.

The U.S., for example, is the number one plastic polluter per capita, but only recycles 5% of its plastics. This highlights the need for better technologies and infrastructure to process different types of plastic waste. Currently, most technologies melt down plastic bottles and downcycle them into lower-quality products. However, recent studies have offered more sustainable solutions, such as harnessing moisture from the air to break down plastics and recycle or upcycle them into more valuable materials.

Microplastic contamination has also become widespread, with wastewater acting as a major reservoir. Microplastics are known to host bacterial communities on their surfaces, a phenomenon known as the "plastisphere". Studies have shown that different types of plastics, such as polystyrene, polyethylene, and polypropylene, can incubate Escherichia coli for up to 10 days, contributing to antimicrobial resistance.

Plastic waste has increased dramatically since the 1950s, with global plastic production increasing nearly 230-fold to 460 million tonnes in 2019. The world produces around 350 million tonnes of plastic waste each year, with between 1 and 2 million tonnes of plastic entering the oceans annually. Rich countries tend to produce the most plastic waste per person, and the U.S. is the number one plastic polluter per capita. Northwestern's Yosi Kratish, the co-corresponding author of a study on plastic pollution, stated that the U.S. only recycles 5% of its plastics. This is due in part to a lack of technology to process different types of plastic waste. Most technologies today melt down plastic bottles and downcycle them into lower-quality products.

Microplastic contamination has become widespread as plastic use has increased globally, with wastewater acting as a major reservoir. Microplastics are known to host bacterial communities on their surfaces, a phenomenon known as the "plastisphere". While rich countries produce more plastic waste per person, mismanaged waste tends to be much higher in low-to-middle-income countries due to poorer waste management infrastructure. As a result, most plastic flowing into the ocean today comes from middle-income countries, particularly across Asia.

Global plastic production has doubled in the last two decades

The U.S. is the number one plastic polluter per capita, and only 5% of plastics are recycled. This is due in part to the lack of technology to process different types of plastic waste. Most technologies today melt down plastic bottles and downcycle them into lower-quality products. However, new research from Northwestern University has found a way to break down plastics using moisture from the air, achieving an exceptionally clean and selective process. This technology could be used to recycle or upcycle plastics into more valuable materials.

As plastic use has increased globally, microplastic contamination has become widespread, with wastewater acting as a major reservoir. Microplastics are known to host bacterial communities on their surfaces, a phenomenon referred to as the "plastisphere". Studies have shown that different types of plastic, such as polystyrene, polyethylene, and polypropylene, can incubate Escherichia coli for up to 10 days. This contributes to the rise of antimicrobial resistance, with environmental factors playing a key role.

In 2018, plastic products generation was 35.7 million tons, or 12.2% of generation. This rapid growth in global plastic production began in the 1950s and has increased nearly 230-fold over the next 70 years.

The U.S. is the number one plastic polluter per capita, and only recycles 5% of its plastics. There is a dire need for better technologies that can process different types of plastic waste. Most of the technologies that we have today melt down plastic bottles and downcycle them into lower-quality products.
