The World's Plastic Production Problem: A Global Crisis

Plastic is everywhere, from the deepest oceans to the highest mountaintops, and even inside our bodies. The world produces around 350 million tons of plastic waste each year, with global production doubling in the last two decades. The first synthetic plastic, Bakelite, was produced in 1907, but rapid growth in global plastic production didn't occur until the 1950s. Since then, the amount of plastic produced annually has skyrocketed from 2 million tons in 1950 to over 390 million tons in 2021. This waste is a significant issue, as it can take up to 500 years to decompose, polluting the environment and harming wildlife and human health.

Global plastic production has doubled since the 2000s

Plastic has become an integral part of our lives due to its versatility, affordability, and sterility. It is used in construction, home appliances, medical instruments, and food packaging. However, the improper management of plastic waste, such as the lack of recycling or inadequate disposal methods, contributes to environmental pollution. Richer countries produce the most plastic waste per person, but the mismanagement of waste, especially in low-to-middle-income countries, is a critical factor in tackling the problem of ocean plastics.

The global plastic production landscape is dominated by Asia, with China alone accounting for 32% of global production in 2022. North America ranks second, with a 17% share in the same year. The production process involves acquiring raw materials, synthesizing basic polymers, compounding them into usable fractions, and finally, molding or shaping the plastic.

While the average lifespan of plastic products is around 10 years, plastics can take up to 500 years to decompose, depending on their composition and disposal method. The accumulation of plastic waste in the environment has severe consequences for human health, ecosystems, and wildlife, especially marine species. To address this issue, improved waste management practices, such as recycling and proper disposal, are crucial. Additionally, implementing new measures and policies, such as increased taxes on plastic use and a better global recycling system, can help reduce the amount of plastic waste.

Plastic waste management methods

Global plastic production has doubled in the last two decades, with the world producing almost 400 million metric tons per year as of 2021. Humans currently produce more than 350 million metric tons of plastic waste per year, and without policy changes, this figure is projected to triple by 2060.

Recycling: This involves converting plastic waste into reusable material or fuel, such as gasoline, kerosene, or diesel. Recycling is considered the best option for minimizing the impact of plastic waste. It reduces the amount of waste that needs to be disposed of and also lowers CO2 emissions and oil use. However, it is important to note that less than 10% of plastic waste is currently recycled annually.

Incineration: Incineration is the process of turning plastic waste into ash, flue gas, and heat. The heat generated during incineration can be used for energy recovery, such as electricity production. While incineration requires very little space, it is important to ensure that the flue gases are cleared of pollutants before being released into the atmosphere.

Landfill: Landfill refers to disposing of plastic waste in designated areas and burying it beneath the Earth's surface. However, landfills take up valuable space that could be used for more profitable activities, like agriculture. Most plastics only moderately degrade, rendering the land contaminated and inaccessible for extended periods.

Microbial Degradation: This method involves using microorganisms, such as enzymes, to break down plastic waste into less complex structures.

Conversion into Valuable Materials: Plastic waste can be converted into valuable materials or products through processes like waste-to-energy or waste-to-oil initiatives.

It is important to note that the effectiveness of these methods depends on various factors, including the availability of resources, infrastructure, and global policies. Additionally, improving waste management practices in low-to-middle-income countries, where most ocean plastics originate, is crucial to combating plastic pollution.

Plastic pollution in the oceans

The primary sources of ocean plastic pollution are the mismanaged disposal of plastic waste and the relentless production and consumption of plastic materials. Globally, about 350 million tonnes of plastic waste are generated annually, with rich countries producing the most plastic waste per person. However, the critical issue is the mismanagement of this waste, predominantly in low-to-middle-income countries. When plastic waste is not recycled, incinerated, or properly landfilled, it becomes vulnerable to polluting the environment and eventually finds its way into the oceans.

It is estimated that between 1 and 11 million metric tonnes of plastic enter the oceans each year, with some estimates reaching 8 million tonnes. This plastic pollution in the oceans takes various forms, from microplastics to larger items like bottles, bags, and ghost nets. Microplastics, resulting from the breakdown of plastic waste, are particularly concerning as they can mimic fish eggs and be consumed by marine life, entering the ocean food chain. Once in the ocean, microplastics are nearly impossible to filter out, becoming a permanent fixture in the ecosystem.

The impact of plastic pollution on marine life is devastating. It entangles and restricts the movement of various species, causing starvation, laceration, infection, and suffocation. Additionally, plastic waste obstructs the respiratory and digestive tracts of turtles and seabirds, leading to fatal consequences. The accumulation of plastic in the oceans also poses a threat to human health, as microplastics can infiltrate the food chain and have unknown effects on those who consume seafood.

To address the pressing issue of plastic pollution in the oceans, systemic change is necessary. Governments, industries, communities, and individuals must work together to reduce plastic consumption, improve waste management practices, and implement large-scale solutions. While recycling is important, it is not economically viable for all types of plastic pollution, especially microplastics. Therefore, a comprehensive approach that addresses the full life cycle of plastic, including production, design, and disposal, is crucial to safeguarding our oceans and promoting a sustainable future for both the environment and humanity.

Plastic recycling

Plastic is a cheap and versatile material used in a variety of applications, from construction to food packaging. However, it has become one of the biggest environmental issues, with plastic waste polluting ecosystems and affecting wildlife and human health. While global plastic production has doubled since the turn of the century, reaching almost 400 million metric tons per year in 2021, the management of plastic waste has not kept pace. It is estimated that around 350 million tons of plastic waste are generated annually, with one to two million tons ending up in the oceans each year.

The good news is that plastic recycling rates are increasing worldwide, albeit slowly. Recycling is a $200 billion industry, and some countries are leading the way with impressive recycling rates. For example, South Korea, Germany, and Austria have been consistently named as top performers in plastic recycling. In 2018, South Korea recycled over 80% of its plastic waste, and it continues to maintain a high rate, estimated at 59% in 2024. Germany, with its comprehensive waste management system, recycled close to 56% of its waste in 2017 and is estimated to have a recycling rate of 65%. The UK also set a record in 2023, recycling 52.5% of its plastic waste.

These countries have implemented various policies and initiatives to encourage recycling. South Korea, for instance, has a strong waste collection system and has implemented bans on certain plastic items. Germany uses a "green dot" system, where producers and retailers place a green dot on recyclable packaging, encouraging consumers to separate and recycle waste. The EU has set a target of recycling 90% of plastic packaging by 2029, and Norway has already achieved this goal.

While these developments are encouraging, there is still a long way to go. Currently, less than 10% of plastic waste is recycled annually, with the majority being landfilled or incinerated, releasing harmful pollutants. To address this, new measures and policies are needed, such as improved global recycling systems and taxes on plastic use. Additionally, it is important to focus on reducing plastic production and promoting reusable alternatives to curb the growing plastic waste crisis.

Plastic waste trade

The world currently produces around 350 million metric tons of plastic waste per year, with global plastic production doubling since the turn of the century. This waste is either recycled, incinerated, or sent to landfills. However, one-fifth to one-quarter of plastic waste is mismanaged, becoming a significant environmental pollutant.

Rich countries tend to produce the most plastic waste per person, and a small percentage of this waste is exported overseas. In 2020, around 5 million tonnes of plastic waste were traded globally, with Europe being the biggest exporter and importer. While most plastic is traded within a given region, such as Europe and Asia, other countries have emerged as major importers since China's ban on importing plastic waste in 2017. These include Malaysia, Vietnam, Indonesia, the Philippines, and Turkey.

The global trade in plastic waste has mirrored the growth in global plastic production, allowing high-income countries to avoid the direct social and environmental impacts of their plastic waste. It has also driven the ever-expanding production and consumption of new plastics. The plastic waste trade fuels organized crime, human rights violations, and environmental destruction, with millions of tonnes of waste dumped in countries ill-equipped to manage it effectively.

To address the plastic waste trade, stricter controls and international legally binding agreements are being advocated, such as amendments to the European Union's Waste Shipment Regulation and the Basel Convention. These measures aim to ban plastic waste exports to non-EU countries and introduce stringent measures for intra-EU trade, ensuring that plastic waste is managed in an environmentally and socially responsible manner.
