The Plastic Crisis: Understanding Global Production Rates

Plastic is everywhere. It is used in almost all consumer and industrial activities, from construction and vehicles to electronics and agriculture. The world produces around 350-460 million tons of plastic waste each year, and this number is projected to triple by 2060. Asia is the largest producer of plastic, with China alone accounting for 32% of global production in 2022. While rich countries produce the most plastic waste per person, low-to-middle-income countries tend to have higher rates of plastic mismanagement, which refers to plastic that is not recycled, incinerated, or kept in sealed landfills. As a result, most plastic flowing into the ocean today comes from middle-income countries, particularly in Asia. Plastic pollution has become one of the biggest issues facing the planet, with its impacts stretching from the tallest mountains to the deepest ocean trenches. It affects human health, destroys ecosystems, harms wildlife, burdens economic activities, and contributes to climate change.

Plastic production in Asia

Asia is the world's largest producer of plastic, accounting for approximately 50-51% of global plastic production. China is the largest producer within Asia, responsible for 31-32% of the world's plastic production in 2019 and 2022. China produces between 6 and 12 million metric tons of plastic products each month, with an annual per capita production of 82 kg in 2019. Other major plastic-producing countries in Asia include India and South Korea, with 14.17 and 13.68 Mt of production, respectively. In 2015, Asia manufactured about 131 Mt of plastic resins, with China's share being 44.79 Mt.

Asia is also a significant recipient of plastic waste, with about 74% of the world's exported plastic waste entering the region in recent years. China (mainland) was the largest importer of plastic waste until 2017, receiving over 5.8 Mt/year. Middle-income countries in Asia, in particular, are responsible for much of the plastic flowing into the ocean today due to poor waste management infrastructure.

To address plastic pollution, it is crucial to improve waste management practices and reduce plastic waste generation. While reducing plastic production can help, the more critical factor is ensuring that waste is adequately recycled, incinerated, or disposed of in sealed landfills to prevent it from leaking into the environment and oceans.

Plastic waste in oceans

The world produced around 350 million tonnes of plastic waste in 2022, with an estimated 8 million tonnes ending up in the oceans. This means that 0.5% of plastic waste ends up in the ocean. However, if this trend continues, it is predicted that there will be more plastic than fish in the ocean by 2050.

Microplastics, particles less than 5 millimetres in width, are a significant concern. They can be generated from various sources, including vehicle tyres, textiles, and personal care products like liquid soaps and shampoos. Once in the ocean, microplastics are nearly impossible to filter out and become a permanent part of the ecosystem. They can be mistaken for fish eggs or tiny organisms and ingested by marine life, potentially entering our food chain with unknown health consequences.

Richer countries produce more plastic waste per person, but the critical issue is the mismanagement of this waste, which is more prevalent in low-to-middle-income countries due to poorer waste management infrastructure. Asia is the largest plastics producer, with China alone accounting for 32% of global production and being one of the leading sources of mismanaged plastic waste. However, the problem requires a global effort, including cooperation between governments, industries, scientists, NGOs, and consumers, to implement solutions effectively.

To address plastic waste in oceans, a multifaceted approach is necessary. This includes reducing plastic production and consumption, improving recycling infrastructure and product redesign, and trapping plastic particles at river mouths before they enter the ocean. While the task is challenging, humanity already possesses the necessary technologies and policy structures to make a difference.

Plastic recycling

Plastic is everywhere, from the deepest ocean trenches to the tallest mountains. It is used in almost all consumer and industrial activities, from construction and vehicles to electronics and agriculture. The world produces around 350 to 460 million tons of plastic waste each year, with global production doubling since the beginning of the century. The largest producer of plastic is Asia, with China alone accounting for 32% of global production in 2022. North America is the second-largest producer, with a 17% share in 2022.

The problem of plastic waste is not just about the amount of plastic being produced but also about how it is managed. Richer countries produce the most plastic waste per person, but they also have better waste management infrastructure. As a result, middle-income countries, particularly in Asia, are responsible for most of the plastic that ends up in the ocean. Around one-fifth to one-quarter of plastics are mismanaged, meaning they are not recycled, incinerated, or kept in sealed landfills. Instead, they are often disposed of at illegal dumpsites or burned in open pits, allowing them to leak into the environment and pollute rivers and oceans.

To address the problem of plastic waste, it is essential to reduce plastic production and increase the circularity of supply and value chains. This includes reusing, refilling, and recycling plastics. While some countries have made positive efforts, such as banning certain single-use plastics, a global plastics treaty is needed to reduce plastic production, phase out harmful subsidies, and eliminate harmful products and chemicals.

There are several challenges to plastic recycling. First, not all plastics are recyclable, and those that are can only be recycled a limited number of times before the material becomes too weak. Second, the recycling process itself requires energy and resources, and the infrastructure for plastic recycling is not sufficiently developed in many countries. Finally, consumer behaviour plays a significant role in plastic recycling. Consumers must be encouraged to reduce their use of single-use plastics and to dispose of plastics properly to ensure they can be recycled.

Plastic pollution and the environment

Plastic pollution is one of the most pressing issues facing the planet today. The world currently produces over 400 million metric tons of plastic annually, with Asia being the largest producer, and China alone accounting for 32% of global production. The production of plastic has been increasing, with global production doubling since 2000. This has resulted in a corresponding increase in plastic waste, with an estimated 20 million metric tons of plastic waste polluting the environment each year. This waste is found in all ecosystems, from the tallest mountains to the deepest ocean trenches, and has severe consequences for human health, ecosystems, and wildlife.

Richer nations tend to produce the most plastic waste per person. However, the critical issue is the mismanagement of this waste, which is more prevalent in low-to-middle-income countries due to inadequate waste management infrastructure. Mismanaged waste is often disposed of in illegal dumpsites or burned in open pits, and it also leaks into rivers and oceans. Between 1970 and 2019, an estimated 30 million metric tons of plastic accumulated in the ocean, while more than 100 million tons accumulated in rivers and lakes. Asia is responsible for over 80% of the plastic waste in the ocean, with waste from wealthier regions also contributing significantly.

The impact of plastic pollution is far-reaching. It affects human health, with microplastics found in human blood, placentas, food, and drinks. The chemicals used in plastic production are known to cause various health issues, including cancer. Plastic pollution also harms ecosystems, with marine life being particularly vulnerable. It contributes to biodiversity loss, ecosystem degradation, and climate change. Additionally, the economic consequences are significant, impacting sectors such as small and medium enterprises, tourism, and trade.

To address plastic pollution, it is essential to reduce plastic production and phase out harmful products and chemicals. This requires collective action on a global scale, including public and private investment in infrastructure, improved waste management practices, and changes in consumer behaviour. Banning certain single-use plastics and promoting circular economy solutions like reuse and refill initiatives are positive steps towards tackling this pressing issue.

Plastic production in the US

Plastic production and consumption have soared in the past few decades since plastic became commercially produced, and it is now ubiquitous in daily life. As one of the world's largest consumers of plastics, the United States is a major contributor to the growing global plastic waste problem.

In 2018, the total generation of plastics in the US was 35.7 million tons, which was 12.2% of Municipal Solid Waste (MSW) generation. The containers and packaging category had the most plastic tonnage at over 14.5 million tons in 2018. This category includes bags, sacks, wraps, other packaging, PET bottles and jars, and HDPE natural bottles. Manufacturers also use plastic in durable goods, such as appliances, furniture, casings of lead-acid batteries, and other products.

The recycling rate of plastics in the US is relatively small. In 2018, the total amount of recycled plastics was 3 million tons, with an 8.7% recycling rate. The recycling rate of PET bottles and jars was 29.1% in 2018, and the rate for HDPE natural bottles was 29.3%. However, even plastics that make it to recycling facilities may not be recycled, with 30 to 36% of PET bottles wasted during the recycling process. In 2021, the US plastic waste exports decreased to 0.61 million tons as countries like China stopped accepting America's waste.

The demand for plastics in the US does not show signs of slowing down, and plastic waste generation is projected to surpass 140 million metric tons by 2060. This plastic waste has severe environmental consequences, polluting land, oceans, air, and even food and human blood.
