Plastic Pollution's Impact On China's Environment And Health

China is one of the world's biggest users and producers of plastic, accounting for 29% of global production. In 2010, China generated 60 million tons of plastic waste, more than any other country. As a result, China has been struggling to deal with the rubbish generated by its 1.4 billion citizens. In 2019, more than 200 million cubic meters of waste was found floating off Chinese shores, with plastic accounting for the vast majority of the rubbish. China's plastic pollution has had a significant impact on its coastal waters and rivers, with debris hitting the highest level in a decade. To combat this issue, China has implemented various measures, including banning single-use plastic bags and straws, reducing the use of single-use plastic items in the restaurant industry, and instituting waste sorting and recycling programs.

China's plastic pollution solutions

China has implemented a range of solutions to tackle its plastic pollution problem, which has been exacerbated by its position as the world's biggest producer and consumer of plastics. Here is an overview of China's plastic pollution solutions:

Bans on Single-Use Plastics

China has introduced a series of bans on single-use plastics to reduce plastic waste. In 2008, the country banned retailers from providing free plastic bags and prohibited the production of ultra-thin plastic bags. In 2020, non-degradable bags were banned in major cities, with a plan to extend this to all cities and towns by 2022. The production and sale of plastic bags below a certain thickness were also prohibited. The restaurant industry was instructed to stop using single-use plastic straws and reduce their overall use of single-use plastic items by 30%. Hotels were told not to offer free single-use plastic items by 2025.

Waste Management Improvements

China has recognised the need to improve its waste management practices to tackle plastic pollution. In 2018, the country banned the import of foreign plastic waste, which was a significant contributor to its domestic waste problem. The National Sword policy aimed to address the environmental and health challenges posed by low-tech waste sorting operations and focus on solving China's domestic waste crisis. Additionally, the Chinese government introduced new laws and regulations in 2020 to limit plastic waste, with a detailed roadmap for 2021-2025 that includes phasing out single-use plastics and boosting recycling efforts.

Encouraging Citizen Action and Awareness

China has witnessed the emergence of citizen-led initiatives to combat plastic pollution. Organisations like Shanghai Rendu Ocean NGO Development Center have organised waste pick-up events along the Shanghai coastline, engaging the public in ocean protection. These clean-up efforts have also evolved into citizen science data collection activities, with volunteers identifying and recording brands and materials of collected waste to raise awareness and hold corporations accountable.

International Collaboration and Investments

China has sought international collaboration and investments to support its plastic pollution reduction efforts. The World Bank approved a $250 million loan for the Plastic Waste Reduction Project (Shaanxi) to improve plastic waste management, reduce plastic pollution, and establish models for integrated waste management in rural areas. This project aims to inform and replicate successful approaches in other provinces and contribute to national-level policy work.

Promoting Alternatives and Biodegradable Plastics

China's plan for 2021-2025 includes promoting alternatives to plastic, such as bamboo, wood, and paper. The country also intends to encourage scientific research into biodegradable plastics to develop more environmentally friendly options.

Plastic pollution in China's rivers

China's plastic pollution problem is a complex issue that has far-reaching consequences for the environment and public health. The country's rapid economic growth and urbanisation have led to a significant increase in plastic consumption, with single-use plastics being a major contributor. China's rivers, in particular, bear the brunt of this pollution, and here is an in-depth look at the issue.

China's vast river systems, including the Yangtze, Yellow, Hai, Pearl, and Mekong, have become conduits for plastic waste, with serious ecological consequences. A 2017 study revealed that six of the top ten rivers contributing plastic pollution to the oceans are in China. These rivers carry a staggering amount of plastic debris, from bottles and bags to microscopic fibres, posing a significant threat to aquatic life and ecosystems.

Sources of Plastic Pollution:

The primary sources of plastic pollution in China's rivers can be attributed to two main factors: urbanisation and crop production. Mismanaged solid waste from urban and rural areas is the most significant contributor, accounting for 65% of macro and microplastics in rivers. This includes plastic waste that is not properly recycled, incinerated, or disposed of in sealed landfills. Population density and inadequate waste management practices exacerbate the problem, with plastic waste often ending up in rivers through runoff and discharge.

Agricultural practices, such as the use of plastic films for mulching and greenhouses, also contribute to river pollution. While agricultural plastic films account for a smaller proportion of river pollution, they still play a significant role, especially in certain regions. Poor collection and recycling practices leave plastic residues in soils, which are then washed into rivers during rainfall or irrigation.

Impact on the Environment and Public Health:

The impact of plastic pollution in China's rivers is profound and far-reaching. Plastic waste breaks down into microplastics, which can be ingested by marine organisms, leading to their sickness or death. It also affects the food chain, as plastics accumulate in the tissues of aquatic organisms, eventually reaching humans through consumption. Additionally, plastic pollution can damage critical infrastructure, such as water treatment plants, and disrupt natural processes, such as river flow and sedimentation.

Efforts to Combat Plastic Pollution:

Recognising the severity of the issue, China has implemented several measures to combat plastic pollution in its rivers. The country has banned single-use plastic bags and straws, with plans to extend these bans to other plastic items. Additionally, China has promoted waste sorting and recycling initiatives, with some cities implementing compulsory waste sorting policies. NGOs and grassroots organisations are also actively working to raise public awareness, clean up riverbanks, and advocate for corporate responsibility.

Plastic pollution in China's seas

China's seas are facing a grave threat from plastic pollution, with the country being one of the biggest contributors to ocean plastic pollution globally. In recent years, China has taken some significant steps to tackle this issue, but it continues to be a pressing environmental challenge.

Sources of Plastic Pollution in China's Seas

China's vast coastline includes the Yangtze and Pearl River deltas, which are major industrial zones. These areas have been identified as significant sources of plastic pollution, with wastewater and trash dumping contributing to the problem. The Yangtze River alone has been linked to over half of all marine plastic pollution globally, although more recent studies suggest that the Philippines is now a larger contributor.

China's Efforts to Address Plastic Pollution in its Seas

Recognizing the severity of the issue, China has implemented several measures to tackle plastic pollution in its seas. In 2017, China banned the import of foreign plastic waste, a move that had significant impacts on global plastic trade flows. Domestically, China has also introduced bans on single-use plastic bags and straws, with varying levels of success. There has also been a rise in activism and citizen initiatives aimed at cleaning up beaches and raising awareness about ocean plastics.

In 2020, China introduced a raft of new laws and regulations, including the phase-out of single-use plastics, targets for cutting plastic production and waste, and boosting recycling efforts. The government is also encouraging the use of alternatives like bamboo and paper and promoting scientific research into biodegradable plastics.

Challenges and Future Prospects

While China has made notable efforts, challenges remain. There is a lack of enforcement and public education regarding plastic waste management, and the rapid rise of e-commerce and delivery services has led to an increase in plastic packaging. Additionally, China's large population and growing economy continue to put pressure on its waste management systems.

Looking ahead, China's plans include clearing plastic waste from key lakes, rivers, tourist attractions, and rural areas, as well as increasing waste incineration capabilities. The country's ambitious 2060 carbon neutrality targets also align with its efforts to reduce plastic pollution. However, to make a significant and lasting impact, China will need to address the upstream production of plastics and involvement of the extractive resources industry and chemical companies.

China's plastic waste imports

In 2017, China announced it would ban the import of foreign plastic waste as part of its National Sword policy, which came into effect in January 2018. This decision sent shockwaves through the global recycling industry, as countries that had relied on sending their plastic waste to China scrambled for alternatives. The ban covered most plastics and other materials, with only the cleanest and highest-grade materials still allowed to be imported, following a stricter 99.5% purity standard.

The impact of China's ban on plastic waste imports was significant, with global recycling programs disrupted and rising costs for managing plastic waste. Communities and recycling processors in the US and Europe were particularly hard hit, with many having to curtail or halt their recycling programs. This led to an increase in plastic waste being sent to landfills, incinerators, or simply being littered into the environment.

However, some experts see China's ban as an opportunity to develop better solutions for the growing throwaway culture and to spur the development of more easily recyclable products. It has also led to efforts to expand domestic processing capacities in North America, Europe, and some Southeast Asian countries.

China's plastic waste exports

The ban resulted in a sharp decline in global plastic waste trade, with China's plastic imports plummeting by 99%. Countries like the United States, which exported around 4000 shipping containers of garbage to China daily before the ban, had to reroute their waste to other nations, primarily in Southeast Asia. However, these countries soon became overwhelmed and imposed their own restrictions on waste imports, leading to a global recycling crisis.

The ban exposed the overreliance of many countries on China for waste management and the lack of adequate infrastructure to handle their own waste. It also highlighted the environmental repercussions of the waste-recycling industry, which contributed to air and water pollution in China.

While the immediate effects of the ban caused disruptions, it also presented an opportunity for countries to develop better solutions for managing their waste and reducing their reliance on plastic. China's decision to ban plastic waste imports is a significant step in addressing the global issue of plastic pollution and has sparked conversations about the need to reduce, reuse, and recycle plastic waste effectively.
