The World's Plastic Production Problem: How Much Is Too Much?

Plastic is a relatively new invention, with the first examples dating back to the late 1800s. However, its low production cost and versatility have made it one of the most widely used materials today. In 2023, the world produced 413.8 million metric tons of plastic, with China alone accounting for 32% of global production. The annual plastic consumption per person in Western Europe is around 150kg, more than twice the global average of 60kg. While plastic is used in a wide range of products, one of its main applications is packaging. The production of plastic has severe environmental and health impacts, with plastic waste polluting ecosystems and harming wildlife, especially marine species.

Plastic production in Asia

Asia is the world's largest plastic-producing region, accounting for more than half of the world's plastic production. In 2019, Asia was responsible for approximately 51% of the world's total plastic production, with China being the largest producer at 31%. This is a notable increase from 2013-2015, when plastic production in Asia was between 114 and 131 Mt, with China's share at 44.79 Mt. The next largest producers in Asia are India and South Korea, with 14.17 Mt and 13.68 Mt, respectively.

Asia has become a critical region for plastic production and consumption, with its share of global plastic production steadily increasing over the years. The region's large population and growing economies contribute significantly to the demand for plastic products. Additionally, Asia is a leading manufacturer and trader of plastic waste, importing 74% of the world's plastic waste. China was the largest importer of plastic waste until 2017, receiving over 5.8 Mt/year.

The high volume of plastic production and consumption in Asia has led to significant plastic waste generation. The estimated amount of plastic waste produced by Asian countries in 2016 was about 121 Mt. However, it is important to note that plastic waste is not limited to the region where it is produced, as global trade allows for the movement of plastic waste between countries.

Plastic waste is a pressing issue facing the planet, with its impacts felt in various environments, from the deepest oceans to the highest mountains. It poses risks to human health, destroys ecosystems, and harms wildlife, particularly marine species. The long decomposition time of plastics, up to 500 years, exacerbates the problem. Efforts to reduce plastic waste are crucial to mitigate these negative consequences, and some countries in Asia, like China, have taken steps towards reducing waste.

While the exact breakdown of plastic production by country in Asia varies year to year, the region's overall output remains significant. The high level of plastic production in Asia underscores the need for sustainable practices and effective waste management policies to address the growing environmental challenges associated with plastic pollution.

Plastic waste in the Global South

The world currently produces over 350 million metric tons of plastic waste per year, with global plastic production doubling since the beginning of the century to almost 400 million metric tons per year in 2021. A recent study has found that the world produces 57 million tons of plastic pollution per year, and that more than two-thirds of this comes from countries in the Global South.

The Global South has been described as bearing the brunt of the Global North's plastic waste. The Global North has been criticised for exporting plastic waste to the Global South, which has been described as "waste colonialism". This has been seen in Southeast Asian countries, which have become the new dumping ground for plastic waste since China banned importing rubbish in 2016. Malaysia, for example, has returned containers of plastic waste to their countries of origin, including the United States, the United Kingdom, France, Canada, Singapore, and Spain.

The plastic waste crisis has had a significant impact on the environment and communities in the Global South, destroying ecosystems and threatening food security, human health, and economic development. Coastal cities in Indonesia, for instance, have waste overflowing into the ocean, disrupting marine ecosystems and killing wildlife. The plastic waste also ends up in humans' digestive systems, as seafood is the primary source of food for these communities.

Some countries in the Global South have started to take action to address the plastic waste crisis. Vietnam became the first country in Southeast Asia to enact an "Extended Producer Responsibility" (EPR) law in 2022, which requires producers and importers to manage their products' full lifecycles, including collection, sorting, recycling, and final disposal. Chile was one of the first six countries in the world to sign up for the New Plastics Economy Global Commitment in 2018, which aims to eliminate "unnecessary plastics" by 2025. Social enterprises, such as Algramo in Santiago, have also been working to reduce plastic waste and address social inequality.

Plastic waste in Europe

Plastic waste is a significant issue facing the world today, with its impact felt from the deepest oceans to the highest mountains. The problem has been exacerbated in recent decades as the consumption of this versatile material has increased. While the lifespan of plastic products averages about 10 years, they can take up to 500 years to decompose, depending on their composition and disposal method.

In Europe, the primary method of disposing of plastic waste is energy recovery, which involves converting plastic waste into usable heat, electricity, or fuel through incineration or other processes. Recycling is the second most common method, but Europe faces challenges such as a lack of capacity, technology, or financial resources to treat waste locally. As a result, about half of the plastic collected for recycling is exported to non-EU countries, with Turkey, India, and Egypt being the main destinations.

The European Union (EU) is taking action to address plastic pollution and marine litter, with specific rules and targets for single-use plastics, plastic packaging, and microplastics. The EU's plastics strategy, as part of the circular economy action plan, aims to protect the environment and human health by reducing marine litter, greenhouse gas emissions, and dependence on imported fossil fuels. The EU is also addressing the sourcing, labelling, and use of bio-based, biodegradable, and compostable plastics.

Despite these efforts, plastic waste generation in the EU is set to increase, while recycling rates stagnate. This could lead to more incineration and landfilling of plastic waste. The low recycling rate results in significant economic and environmental losses, with about 22 million tonnes of plastic ending up in soils, rivers, and oceans in 2019. By 2060, plastic leakage is projected to double, and emissions from the plastics lifecycle are expected to more than double, reaching 4.3 billion tonnes of GHG emissions.

To address these challenges, the EU has set targets as part of the Green Deal, aiming for 55% of plastic packaging waste to be recycled by 2030. MEPs have also called for stricter requirements for waste shipments outside the EU, prohibiting plastic waste exports to non-OECD countries.

Plastic production in the US

Plastic waste is one of the most pressing issues facing the planet today, with plastic polluting the deepest ocean trenches and the tallest mountains, and affecting human health, wildlife, and ecosystems. The global production of plastics has doubled since the beginning of the century, reaching almost 400 million metric tons per year in 2021.

The United States plays a significant role in plastic production worldwide. In 2018, the US generated 35.7 million tons of plastic, accounting for 12.2% of Municipal Solid Waste (MSW) generation. While the recycling rate of plastic waste in the US is relatively low at 8.7% in 2018, there have been efforts to improve this. The recycling rate for specific plastic containers, such as PET bottles and jars, and HDPE natural bottles, was higher, at around 29%. The US Environmental Protection Agency (EPA) classifies plastic materials based on their generation, recycling, combustion with energy recovery, and landfilling. The American Chemistry Council's Plastics Division represents America's plastic manufacturers and innovators, aiming for 100% of US plastic packaging to be reused, recycled, or recovered by 2040.

The plastic industry in the US is economically significant, generating over a million jobs and contributing to key industries such as manufacturing, packaging, and construction. In 2023, the US imported plastic machinery worth $1.8 billion, indicating the importance of plastic conversion and manufacturing in the country. However, there was a decline in plastic product manufacturing in 2023 compared to the previous year, with a significant decrease in production levels from July to August.

The US also contributes to the global issue of plastic waste. In 2023, the US exported plastic waste to other countries, with specific data available from the EPA. Plastic waste from the US ends up in various destinations worldwide, impacting the environment and communities in these regions.

Plastic waste in the oceans

Plastic waste is one of the most pressing issues facing the planet today. It is found everywhere, from the highest mountains to the deepest ocean trenches, and affects human health, destroys ecosystems, and harms wildlife, especially marine life.

The plastic waste problem has been exacerbated in recent decades as plastic consumption has increased. Global plastic production has doubled since the beginning of the century, reaching almost 400 million metric tons per year in 2021. The lifespan of plastic products averages 10 years, yet they can take up to 500 years to decompose, depending on their composition and disposal. Humans currently produce over 350 million metric tons of plastic waste per year, with plastic production projected to continue rising.

A significant amount of plastic waste ends up in the oceans, threatening marine life and ecosystems. It is estimated that about eight million metric tons of plastic entered the ocean in 2010, and the problem has only grown since. Plastic waste in the oceans comes from various land and ocean-based sources and enters the water in multiple ways. One of the significant sources is rivers, with 1000 rivers identified as contributing to 80% of plastic emissions from rivers into the oceans. These rivers make up only 1% of all rivers worldwide, highlighting the concentration of the issue.

The impact of plastic waste in the oceans is devastating for marine life. Marine mammals, such as whales, seabirds, sea turtles, seals, and the endangered Hawaiian monk seals, ingest plastic or become entangled in it, leading to injuries and deaths. Plastic debris, including abandoned fishing nets, breaks down into tiny pieces called microplastics, which can absorb harmful pollutants like pesticides and release them into the ocean. These microplastics are then ingested by marine organisms, potentially impacting their health.

To address the issue of plastic waste in the oceans, local and global organizations are working on cleanup efforts and initiatives. In 2022, 175 countries agreed to create the first legally binding treaty on plastics pollution, including ocean pollution. While this is a significant step forward, the slow nature of change means that the cleanup and prevention of plastic pollution remain an ongoing challenge.
