The World's Plastic Problem: Issuance Statistics

Plastic is a versatile, durable, flexible, and cheap material with a wide range of applications, from construction to food packaging. However, plastic waste is a significant global issue, with an estimated 57 million tons of plastic pollution produced annually, and it is projected to triple by 2060. The mismanagement of plastic waste, including a lack of recycling and improper disposal, leads to environmental pollution, affecting ecosystems and human health. While the lifespan of plastic products is around 10 years, they can take up to 500 years to decompose, contributing to the growing pollution problem.

Global plastic production

Asia is the largest producer of plastic in the world, with China alone accounting for 32% of global production in 2022. China produces between six and 12 million metric tons of plastic products each month. North America is the second-largest producer, with a 17% share in 2022.

The rapid growth in plastic production has had significant environmental impacts. While plastic has added value to our lives as a cheap, versatile, and sterile material used in various industries, its waste is a major pollutant. The world produces around 350 million tonnes of plastic waste each year, with an estimated one to two million tonnes ending up in the oceans. This plastic waste affects wildlife, ecosystems, and human health.

To address plastic pollution, effective waste management is crucial. Currently, only 9% of plastic waste is recycled, while half goes to landfills, and another fifth is mismanaged, increasing the risk of environmental pollution. Domestic policies and foreign investments in waste management infrastructure, especially in low-to-middle-income countries, are essential to tackling this issue.

Plastic waste management

Plastic is a versatile and affordable material used in construction, home appliances, medical instruments, and food packaging. However, the world's rapidly increasing plastic production, which has risen from 2 million tonnes in 1950 to over 450 million today, has led to a corresponding surge in plastic waste.

The world generates 57 million tons of plastic pollution annually, with more than two-thirds originating from the Global South. This plastic waste ends up in oceans, mountaintops, and even inside human bodies. A significant portion, approximately 360 million tons, comes from packaging, while 30% comes from construction, industry, and agriculture.

The improper disposal of plastic waste, such as through incineration or dumping in landfills, poses a severe environmental threat. Currently, only 9% of plastic waste is recycled globally, with half ending up in landfills and another fifth being mismanaged, increasing the risk of leakage into rivers, lakes, and oceans. This mismanagement is particularly prevalent in low-to-middle-income countries, where it contributes significantly to ocean plastic pollution.

To address this pressing issue, a comprehensive plastic waste management framework is essential. The Alliance to End Plastic Waste, in collaboration with Roland Berger, has developed a report offering insights into policies and strategies that countries can adopt to enhance their waste management systems. This includes exploring regulatory policies, infrastructural improvements, and a multi-faceted approach to combat plastic waste. The Extended Producer Responsibility (EPR) and Deposit Return Systems (DRS) are key levers that can be utilised to develop effective national action plans.

Additionally, the unique circumstances of each country must be considered when implementing waste management strategies. While there is no one-size-fits-all solution, improving waste management practices, particularly in poorer countries, is critical to tackling the problem of plastic pollution. This includes investing in waste management infrastructure and implementing domestic policies to ensure proper plastic waste disposal and recycling.

Plastic's impact on the environment

Plastic production has sharply increased over the past seven decades. In 1950, the world produced two million tonnes of plastic. Now, the world produces over 450 million tonnes. This plastic is used in construction, home appliances, medical instruments, and food packaging. However, when plastic waste is not recycled, incinerated, or kept in sealed landfills, it becomes an environmental pollutant.

Plastic pollution is a global problem. Each year, 19 to 23 million tonnes of plastic waste leak into aquatic ecosystems, polluting lakes, rivers, and seas. This pollution affects habitats and natural processes, reducing ecosystems' ability to adapt to climate change, directly impacting millions of people's livelihoods, food production capabilities, and social well-being. One to two million tonnes of plastic enter the oceans annually, endangering wildlife and ecosystems. Plastic pollution has been found everywhere, from the Antarctic tundra to tropical coral reefs. It can take up to 1,000 years for plastic to break down, so when it is discarded, it accumulates in the environment until it reaches a crisis point.

The production of plastic is one of the most energy-intensive manufacturing processes globally, and it contributes to the climate crisis. The material is made from fossil fuels such as crude oil, which are transformed into a polymer using heat and other additives. In 2019, the production and conversion of fossil fuels into new plastic products generated 1.8 billion metric tonnes of greenhouse gas emissions, accounting for 3.4% of the global total. The Organisation for Economic Co-operation and Development (OECD) projects that without intervention, the global plastics industry will account for 20% of total oil consumption and up to 15% of global carbon emissions by 2050.

Plastic pollution poses a threat to marine life, as it can choke and entangle animals, and they may ingest it. Research indicates that more than 1,500 species in marine and terrestrial environments are known to ingest plastics. Plastic pollution also impacts human health, as microplastics are found in drinking water and human tissue.

Plastic pollution in oceans

Plastic pollution in the oceans is a pressing issue that poses significant threats to marine life and ecosystems. It is estimated that around 8 to 11 million metric tons of plastic enter the global ocean each year, with Asian countries contributing an estimated 86% of plastic emissions to the ocean. This plastic pollution comes from a variety of sources, including abandoned fishing nets, microfibers from synthetic clothing, and single-use plastic items such as water bottles, food wrappers, and straws.

One of the main issues with plastic pollution in the oceans is that plastic does not fully biodegrade. Instead, it breaks down into smaller pieces called microplastics and nanoplastics, which can be ingested by marine life, leading to harmful effects on their health. These microplastics have been found in all marine life, from tiny crustaceans in the deepest trenches to larger fish and mammals. They can also enter the human food chain, as they have been detected in human blood, feces, and placentas, with potential unknown impacts on human health.

Another concern is the impact of plastic pollution on marine ecosystems. Plastic debris can entangle marine animals, hindering their movement and feeding abilities. Additionally, plastic waste can be mistaken for food by marine creatures, leading to ingestion and potential harm. The durability and buoyancy of plastic further exacerbate the issue, as it remains floating on the water surface, where many genuine food sources are located, for up to 400 years.

To address the issue of plastic pollution in oceans, a combination of measures needs to be implemented. These include reducing plastic consumption, promoting the use of compostable materials, designing recyclable products and packaging, improving waste management practices, especially in low-to-middle-income countries, and properly disposing of plastic waste that cannot be recycled. Organizations like Ocean Cleanup are actively working to remove plastic from the oceans, and laws such as the Marine Plastic Pollution Research and Control Act (MARPOL) have been enacted to restrict the dumping of plastics at sea.

While the task of cleaning up ocean plastic is challenging, it is not insurmountable. By combining efforts to reduce plastic consumption, improve waste management, and support organizations dedicated to ocean cleanup, we can make significant strides in mitigating the impact of plastic pollution on our oceans and the ecosystems they support.

Plastic's impact on human health

The world produces over 450 million tonnes of plastic annually, with 57 million tonnes of that becoming pollution. This plastic waste ends up in our oceans, rivers, mountaintops, and even the inside of people's bodies.

Plastics' Impact on Human Health

Humans encounter microplastics in the air, water, and food they consume. A study estimates that the average adult ingests approximately 2,000 microplastics per year through salt alone. Microplastics have also been found in tap water, bottled water, seafood, beer, and other commonly consumed beverages.

The production and destruction of plastics produce particles and gases that contribute to climate change, and plastic left to break down in the environment releases greenhouse gases. Studies suggest that microplastics disrupt marine microorganisms' globally crucial roles of sequestering carbon dioxide and producing oxygen, which further jeopardizes our health and that of our planet.

Additionally, the chemicals in and on microplastics, including BPA, phthalates, and heavy metals, are known or suspected to cause nervous, reproductive, and other system disruptions. BPA, for example, is a known endocrine disruptor. While the exact health effects of plastics on humans are challenging to determine, findings in models have shown inflammation, cell death, lung and liver effects, changes in the gut microbiome, and altered lipid and hormone metabolism.

The World Health Organization (WHO) has underscored the need for more research, stating that current technologies don't enable researchers to quantify population-level microplastics exposures or gauge what proportion of those particles stay in our bodies. However, the ubiquity of microplastics in the environment and preliminary findings from human cell and animal studies have led to urgent calls for more research and regulation.
