Plastic Waste: Global Comparison Of Country Contributions

Plastic waste is a pressing global issue, with plastic pollution wreaking havoc on biodiversity, ecosystems, and wildlife. While it is a problem in countries across the world, it is predominantly caused by just 20 countries, with India, Nigeria, and Indonesia being the top three contributors. The amount of plastic waste produced by a country is often linked to its income level, with low-to-middle-income countries struggling with higher levels of plastic waste due to inadequate waste management systems and infrastructure. However, some countries, like China, have taken decisive action to curb plastic waste, resulting in a significant reduction in their waste production.

Top plastic-polluting countries

Plastic waste is a pressing global issue, with plastic wreaking havoc on biodiversity, ecosystems, and wildlife. While larger, more populous countries produce more plastic waste overall, the ranking changes significantly when the results are filtered to show the biggest producers per capita. Here is a list of the top plastic-polluting countries:

India

India is one of the countries with the greatest volume of plastic waste entering the environment. In 2024, India produced 9.3 million tonnes of plastic waste annually. The mismanagement of plastic waste in India has reached critical levels, impacting the health of local communities.

Nigeria

Nigeria is another country where the volume of plastic waste has overwhelmed its ability to manage it effectively. Nigeria generates 3.5 million tonnes of plastic waste each year, contributing significantly to global plastic pollution.

Indonesia

Indonesia is among the top plastic-polluting countries, with 3.4 million tonnes of plastic waste entering the environment annually. The Indonesian government has recognized the severity of the issue and has launched initiatives to reduce marine plastic waste, aiming for a 70% reduction by 2025.

China

China has taken significant steps to curb plastic waste, implementing bans on single-use, non-degradable bags and straws. Despite these efforts, China produced 2.8 million tonnes of plastic waste in 2024, and the mismanagement of plastic refuse remains a critical issue in the country.

United States

The United States is a major contributor to plastic pollution, with over 42 million metric tonnes of plastic waste generated annually. At least 85% of municipal plastic waste in the US is disposed of in landfills, and the country's plastic waste production has increased significantly over the last four decades.

Other Notable Mentions

Other countries that have been identified as significant plastic polluters include Pakistan, Bangladesh, Brazil, Thailand, the Democratic Republic of the Congo, Japan, Germany, and Russia. These countries have varying levels of waste management systems and recycling infrastructure, with some facing challenges in adequately addressing plastic pollution.

Plastic waste management strategies

Plastic waste is a pressing global issue, with an estimated 52 million tonnes of plastic waste entering the environment every year. The management of plastic waste varies across the world, with low-to-middle-income countries tending to have higher rates of plastic waste mismanagement. To tackle this issue, countries have implemented various plastic waste management strategies, which include:

Domestic policies and foreign investments

Domestic policies play a crucial role in improving waste management practices within countries. For example, India has introduced the Plastic Waste Management Rules initiative, which aims to reduce single-use plastic consumption, promote recycling, and raise awareness about proper waste management. Richer countries can also contribute by investing in waste management infrastructure in developing nations.

International collaboration

In March 2022, 175 countries agreed to assemble a treaty to tackle plastic pollution, demonstrating a global commitment to addressing this issue. Additionally, countries have joined transnational coalitions to share knowledge and resources in the fight against plastic waste. For example, Germany has joined a coalition to tackle plastic waste and encourage individuals and businesses to reduce plastic consumption.

Encouraging reusable alternatives

Promoting the use of reusable bags and containers has been shown to drastically reduce the quantity of plastic waste generated. For example, China has taken decisive action by banning single-use, non-biodegradable bags and straws, resulting in a significant reduction in plastic waste production.

Improving recycling infrastructure

Investing in recycling technology and infrastructure is critical to ensuring that more plastic waste is recycled rather than ending up in landfills or the oceans. Norway, for instance, has introduced a plastic bottle deposit system, leading to a high recycling rate and reduced plastic waste.

Public awareness and education

Raising awareness about the environmental and health impacts of plastic waste is essential. By educating the public about the consequences of plastic pollution, countries can encourage individuals to reduce their plastic consumption and dispose of waste properly.

Incentivising sustainable practices

Collaboration between governments and businesses can lead to the development of policies and incentives that encourage the use of sustainable materials and practices. For example, providing incentives for companies to reduce plastic packaging or switch to biodegradable alternatives can have a significant impact on plastic waste reduction.

Impact of plastic waste on wildlife

While researchers are still learning about the scope and scale of plastic's impact on wildlife, it is known that at least 2,144 species have encountered plastic pollution in their natural habitats. Plastic waste affects all land, freshwater, and marine ecosystems, threatening biodiversity and causing ecosystem degradation.

Plastic waste in the oceans is a significant issue, with one to two million tonnes of plastic entering the oceans yearly. It is estimated that up to 90% of seabirds and 52% of sea turtles have mistakenly eaten plastic, leading to starvation as their stomachs become filled with indigestible material. Marine mammals on the Red List of Threatened Species are also impacted, with ghost gear—abandoned fishing gear—affecting 45% of these species. Ghost gear continues to capture wildlife, pollute habitats, and enters the food web as it degrades.

In addition to ingestion, entanglement is another significant outcome of plastic pollution that threatens wildlife. Macroplastics (pieces larger than 0.5 mm) made up 88% of global plastic leakage in 2019 and can clog up rivers and entangle animals. Plastic waste can also alter habitats and natural processes, reducing ecosystems' ability to adapt to climate change and directly affecting the livelihoods of millions of people.

The impact of plastic waste on wildlife is not limited to marine environments. Pollution sources are mainly land-based, coming from urban and stormwater runoff, littering, industrial activities, tyre abrasion, construction, and agriculture. As plastic pollution spreads to every corner of the globe, it is essential to reduce, reuse, and recycle plastic materials to minimize their impact on wildlife and ecosystems.

Domestic policies to improve waste management

The amount of plastic waste generated by a country is influenced by various factors, including population size, economic development, and waste management practices. While larger and more populous countries tend to produce more plastic waste, the per capita production can vary significantly. Developing nations are becoming plastic pollution hotspots as they struggle to effectively manage the increasing volume of waste.

To address the issue of plastic waste, domestic policies that focus on waste management improvements are crucial. Here are some strategies that can be implemented by governments to enhance waste management and reduce plastic pollution:

Promote Recycling and Reuse:

Encourage the recycling and reuse of plastic materials through various initiatives. This can include establishing a circular economy system, as implemented by the Korean government with the Resource Circulation Act (RCA) and the Plastic Waste Control Plan (PWCP). The PWCP aims to reduce plastic waste, improve the circulation system, and increase the recycling rate. Governments can also prioritize the reuse and recycling of plastic waste within their own countries, reducing the need to export waste to other nations.

Ban Single-Use Plastics:

Introduce regulations to ban or restrict the use of single-use plastic items, such as plastic bags, straws, and Styrofoam products. Many countries, including China and Pakistan, have already implemented such bans, contributing to significant reductions in plastic waste production.

Improve Waste Collection and Disposal:

Invest in waste management infrastructure to ensure proper collection and disposal of plastic waste. This includes providing adequate resources for waste collection services and establishing controlled landfills or incineration facilities that meet environmental standards.

Encourage Innovation and Research:

Support the development and commercialization of recycling technologies by providing incentives and funding for research and innovation. Governments can also encourage the use of recycled materials in public projects and offer preferential measures for companies that utilize recycled products.

International Cooperation:

While domestic policies are essential, addressing plastic pollution requires global collaboration. Countries can work together to share best practices, develop international treaties, and invest in waste management infrastructure in developing nations. This collaborative approach will help tackle the issue on a larger scale and ensure that waste management standards are consistent across borders.

By implementing these policies and strategies, governments can significantly improve waste management practices, reduce plastic pollution, and protect the environment and public health. It is important to recognize that each country's specific circumstances will require tailored approaches, but by sharing knowledge and resources, nations can collectively make a substantial impact in addressing the global plastic waste crisis.

Global efforts to tackle plastic pollution

The Global Commitment: Led by the Ellen MacArthur Foundation in partnership with the UN Environment Programme, the Global Commitment has garnered the support of over 1,000 organisations since 2018. Business signatories, representing 20% of the world's plastic packaging industry, have made significant strides in reducing their use of problematic plastic items, stabilising virgin plastic consumption, and increasing recycled content. However, the Foundation also acknowledges that the industry as a whole is lagging, and tougher measures are needed to meet key 2025 goals and prevent an estimated 20 trillion flexible packaging items from ending up in the ocean by 2040.

International Legally Binding Instrument: The ongoing negotiation for an international legally binding instrument on plastic pollution is a crucial step towards establishing rules, measures, and incentives to end this environmental crisis. The agreement, facilitated by the UN Environment Assembly, aims to address all aspects of plastic pollution through science-based policies and a legal framework. The third round of negotiations for this instrument took place in November 2022 in Nairobi, Kenya, with the goal of finalising the agreement by 2024.

Country-Specific Initiatives: Several countries have taken individual initiatives to curb plastic waste. For example, China, once the largest producer of plastic waste, implemented measures to ban single-use, non-degradable bags and straws, resulting in a significant reduction in plastic waste production. India, the second most populated country, passed a comprehensive ban on single-use plastic products in 2022, addressing production, distribution, and use. Other countries like Guatemala and Dominica have also introduced bans on single-use plastics, with Dominica's "Go Green Dominica" initiative focusing on restoring its natural environment.

The European Union's Action Plan: In 2015, the EU created a Circular Economy Action Plan, which includes the European Strategy for Plastics in a Circular Economy. This strategy strengthens regulations on recycling and promotes a more circular method of reusing products, moving away from single-use plastics. The EU aims to reduce the environmental impact of plastic pollution through collaboration between producers, retailers, and consumers.

The Global Tourism Plastics Initiative: This initiative ensures that businesses, governments, and stakeholders take responsibility and work towards reducing plastic pollution. With concrete agreements and terms set to be in place by 2025, it encourages collective action to address the plastic pollution crisis.

While these global efforts demonstrate progress, there is still a long way to go in tackling plastic pollution. The scale of the problem is immense, with almost 70% of plastic waste produced by just 20 countries, and the remaining 30% spread across the rest of the world. Developing nations, in particular, are becoming plastic pollution hotspots, highlighting the need for improved waste management systems and infrastructure.
