Us Plastic Waste: Asia's Unwanted Shipments

The United States has been criticised for exporting large quantities of plastic waste to Asian countries ill-equipped to handle it. In 2018, the US exported 157,000 shipping containers of plastic waste, about one-third of its recycling waste, with 78% of these exports sent to countries with poor waste management systems. China was a major importer of US plastic waste until it tightened its regulations in 2017, causing plastic waste exports to shift to other Asian countries, including Malaysia, Vietnam, Thailand, and Indonesia. Despite a decline in plastic waste exports from the US in recent years, the country continues to ship substantial amounts of plastic scrap overseas, with Southeast Asia bearing the brunt.

China's 2017/2018 ban on plastic waste imports

China, the world's largest producer and consumer of plastics, implemented a ban on foreign waste imports in 2017, which came into effect on 1 January 2018. The ban targeted 24 kinds of solid waste, including eight types of post-consumer plastic scrap, one type of unsorted paper, a dozen types of used textiles, and four metal slags containing vanadium.

The ban was a result of China's struggle with plastic pollution, which had plagued the country for decades. As the world's largest manufacturer of plastic, with a yearly average of 60 million tons, only about 30% of plastic in China was being recycled. Between 2010 and 2016, China imported an average of 8 million tonnes of plastic from over 90 nations, accounting for 56% of the global market for waste plastics.

The 2017/2018 ban had significant repercussions on a global scale, causing a sharp decline in global plastic waste trade flow. Countries that had highly depended on China to manage their waste were forced to reroute their plastic waste to other Southeast Asian nations, such as Thailand, Vietnam, and Malaysia. However, these countries were often ill-equipped to handle the large influx of foreign waste, leading to the implementation of their own waste import restrictions.

The ban has had a positive impact on China's environmental sustainability, increasing the prospects of mitigation of carbon footprint and plastic waste trade flow worldwide. It has also prompted China to introduce policies to phase out single-use plastics and boost recycling.

The United States, one of the main exporters of plastic waste to China, saw a decrease in its scrap plastic exports from 2.3 million tons in 2015 to 1.2 million tons in 2018 and 0.6 million tons in 2021. The US also witnessed a 23.2% increase in landfilling of plastic waste following the ban.

The US's plastic waste export volume

The US has been exporting plastic waste to Asian countries for decades. In 1992, the US began exporting plastic waste to China, which was, until recently, the primary importer of US plastic waste. However, in 2017, China implemented tighter regulations on the import of foreign plastic, resulting in a 92% drop in US plastic waste exports to the country.

Following China's ban, US plastic waste exports shifted towards other Asian countries, mainly Malaysia, Vietnam, Thailand, and Indonesia, as well as South Asian countries such as India. In 2018, the US exported about 1 million tons of plastic waste, with 78% of those exports sent to countries with poor waste management systems. This number increased in 2021, with the US exporting some 1.2 billion pounds (around 544 million tons) of scrap plastic.

The shift in plastic waste exports to Southeast Asian countries has had significant implications for the region. Thailand, for example, has been inundated with plastic waste, with estimates of the volume of plastics spiking since 2018 ranging from 150,000 to more than 550,000 tons, and the actual figures could be even higher. In response, Thailand announced it would restrict plastic waste imports starting in 2024 and implement a complete ban on shipments in 2025. However, enforcement of these restrictions is challenging due to issues such as mislabeled shipments and a lack of transparency and inspection capacity in the customs system.

The export of plastic waste from the US to countries with poor waste management systems has raised concerns about the environmental and human health impacts of this practice. Studies have shown that a large amount of plastic scrap exported from the US does not get recycled but ends up as waste, contributing to plastic pollution and threatening biodiversity and the health of marine life and humans. In addition, the transportation of plastic waste over long distances exacerbates the environmental impact, increasing the carbon footprint of these exports.

While the US has made efforts to address its plastic waste problem, such as developing tools to assess the sustainability and environmental impacts of plastic production, use, and disposal, it is clear that more needs to be done to reduce and repurpose plastic waste. The US must work towards ending the export of plastic waste to countries ill-equipped to manage it and instead focus on finding sustainable solutions to this pressing environmental crisis.

Southeast Asian countries as new importers

Southeast Asian countries have emerged as new importers of plastic waste from the US, following China's ban on waste imports in 2017. This ban caused a significant shift in global plastic waste trade, with the US and other countries redirecting their waste exports to Southeast Asian nations. Countries like Malaysia, Vietnam, Thailand, and Indonesia have become the primary recipients of US plastic waste.

In 2018, the US exported about 157,000 shipping containers or more than 550,000 tons of plastic waste to countries with poor waste management systems, with a significant portion ending up in Southeast Asia. The volume of plastics spiked in the region after China's ban, as the US and other high-income countries sought alternative destinations for their waste.

The influx of plastic waste has had a profound impact on Southeast Asian countries, overwhelming their waste management systems and leading to environmental and health concerns. Thailand, for example, has been particularly affected, with plastic waste imports increasing exponentially between 2018 and 2019. In response, Thailand announced plans to restrict plastic waste imports and enforce a complete ban by 2025. However, enforcement of such bans poses a significant challenge due to issues like mislabeled shipments and a lack of transparency and inspection capacity in customs systems.

The US has been criticized for exporting its plastic waste to countries that are ill-equipped to handle it properly. Despite international agreements to curb the trade in plastic waste, American exporters continue to ship substantial amounts of plastic scrap to poorer countries. This practice has been attributed to recycling companies seeking to avoid the responsibility of waste management by sending it to countries with looser regulations.

The plastic waste exported from the US often ends up in countries with poor waste management practices, contributing to ocean pollution. Southeast Asian countries, despite being blamed for ocean plastic pollution, are themselves inundated with imported plastic waste meant for recycling. This waste is often not properly recycled and ends up in the environment, affecting local communities and ecosystems.

The US's plastic waste recycling rate

The US has been criticised for exporting large amounts of plastic waste to Asia, particularly to Southeast Asian countries like Thailand, Malaysia, Vietnam, and Indonesia. This issue has been exacerbated by China's decision to ban plastic waste imports in 2017, which caused a significant shift in global plastic waste trade flows. As a result, the US has had to find alternative destinations for its plastic waste exports, leading to an increase in exports to the aforementioned Southeast Asian countries.

While the US has made some efforts to address its plastic waste problem, the recycling rate remains low. According to a report by The Last Beach Clean Up and Beyond Plastics, the US recycled only 5-6% of its post-consumer plastic waste in 2021. This is in stark contrast to the recycling rate of paper, which stood at 66% in 2020. The report also highlights the increasing trend in per capita generation of plastic waste, which has risen by 263% since 1980.

The US Plastics Pact, a collaboration between businesses, non-profit organisations, government agencies, and research institutions, aims to address plastic waste at its source by 2025. The pact has set targets such as achieving an average of 30% recycled content or responsibly sourced bio-based content in plastic packaging by 2025. According to their baseline report, 37% of plastic packaging placed on the market by US Pact Activators is reusable, recyclable, or compostable. However, the national recycling rate for plastic packaging is only 13%, indicating that there is still much room for improvement.

The low recycling rate in the US can be attributed to various factors, including the complexity of recycling certain types of plastics, a lack of infrastructure, and the cost of recycling compared to other waste management methods. Additionally, the US has been criticised for its role in contributing to ocean plastic pollution, as a significant portion of its exported plastic waste ends up in countries with poor waste management systems, ultimately leaking into the environment and the oceans.

To improve the plastic waste recycling rate, the US needs to invest in infrastructure that supports reuse, recycling, and composting. There is also a need for policy measures that encourage the production and use of recyclable, reusable, and compostable materials, as well as better enforcement of regulations to ensure responsible waste management practices. By addressing these issues, the US can make significant strides in reducing its plastic waste and improving its recycling rate.

The environmental impact of US plastic waste exports

The volume of plastic waste exported from the US to Southeast Asia is substantial, with estimates ranging from 150,000 to over 550,000 tons, and actual figures potentially even higher. This influx of plastic waste has strained the recycling infrastructure in these countries, leading to the establishment of new recycling facilities with little regulation. The environmental impact of this surge in plastic waste is evident, with plastic pollution affecting terrestrial and aquatic ecosystems, and the burning of scraps contributing to air pollution.

The export of plastic waste from the US has notable environmental and human health impacts. The Global Warming Potential (GWP) is significantly higher when plastics are exported compared to domestic treatment. Transportation exacerbates these impacts, with higher carbon emissions associated with shipping waste overseas. By exporting plastic waste, the US is contributing to the environmental challenges faced by recipient countries, particularly in Southeast Asia.

The US has been criticized for offloading its plastic waste onto developing countries with inadequate waste management systems. John Hocevar, Oceans campaign director for Greenpeace USA, attributed this practice to recycling companies seeking to avoid responsibility for plastic waste management by exporting it to countries with less stringent standards and regulations. This strategy is unsustainable and has led to pushback from Asian countries, with some implementing policies to limit or ban plastic waste imports entirely.

The indirect impact of US plastic waste exports on ocean pollution cannot be overlooked. While rivers in Asia contribute the largest share of plastic entering the oceans, the export of waste from the US to countries with poor waste management systems contributes to this issue. Even in a "best-case" scenario, a small percentage of mismanaged waste can end up in the ocean, and the indirect impact of US exports on ocean pollution is significant.

In conclusion, the environmental impact of US plastic waste exports, particularly to Asia, is extensive. The US's practice of exporting plastic waste has contributed to environmental degradation, human health issues, and ocean pollution. Addressing this complex issue requires a shift towards domestic waste management and sustainable solutions to reduce plastic waste generation.
