Waste management and plastic waste recycling in Japan, China and ASEAN countries: A review

Waste management and plastic waste recycling in Japan, China and ASEAN countries: A review

Plastic pollution: A growing challenge in Asia

Plastic pollution has become a significant environmental challenge, particularly in coastal regions of Asia. The accumulation of plastic waste in oceans and seas has led to severe, irreversible impacts on marine life, ecosystems, and the environment. This is largely due to the lack of effective waste collection, treatment, and management systems in many Asian countries.

The issue is exacerbated by the rapid growth in global plastic production and consumption, which reached 360 million tons in 2018 – a 1.2-fold increase from 299 million tons just 5 years earlier. With a substantial portion of this plastic waste ending up in the environment, it is estimated that 4-12 million metric tons of plastic waste are dumped into the oceans annually worldwide.

In response to this pressing environmental challenge, this article examines the current state of waste management and plastic recycling in three key Asian regions: Japan, China, and the ASEAN countries. By reviewing the existing policies, practices, and performance of these nations, we aim to provide a comprehensive understanding of the plastic pollution crisis in Asia and explore potential solutions to address this global issue.

Waste management and plastic recycling in Japan

Japan has been a pioneer in waste management and recycling policies, introducing several key laws since the 1990s. The Containers and Packaging Recycling Law (1997) was the first major legislation, followed by the Basic Law for the Development of a Circular Society in 2000, which introduced the concept of the ‘3Rs’ – Reduce, Reuse, and Recycle.

More recently, in 2019, Japan published the Resource Circulation Strategy for Plastics, which was followed by the Law for Promotion of Resource Circulation of Plastics in 2021. This law aims to promote the recycling of plastic resources at every stage of the plastic product life cycle, in collaboration with municipalities, businesses, and consumers.

Looking at the data, Japan has seen an 11% reduction in plastic waste generation and a 6% decrease in overall waste generation between 2014 and 2020. The country’s plastic waste recycling rate has remained consistently high, hovering around 80% during this period.

However, the data also shows that Japan is unlikely to meet its 2030 target of a 25% reduction in single-use plastic generation and a 60% recycling rate for plastic waste. To achieve these goals, the country will need to further strengthen implementation of its existing laws and regulations, while also exploring innovative approaches to engage all stakeholders – from municipalities and businesses to individual consumers.

Waste management and plastic recycling in China

As the world’s largest producer of plastics, China has taken several legislative steps in recent years to address the growing issue of plastic pollution. Since the revision of the Law of the People’s Republic of China on the Prevention and Control of Environmental Pollution by Solid Wastes in 2020, the country has been working to improve solid waste management through various regulations and policies.

Key initiatives include the “Opinions on Further Strengthening the Clean-up of Plastic Pollution,” the “Implementing Plan for Improving the Mechanism to Boost Consumption 2018–2020,” and the “Guiding Opinions on Actively Promoting the Innovation and Application of Supply Chains.” These policies aim to move the plastics and packaging industry towards sustainability, environmental protection, and recyclability.

The data shows that China’s waste generation has increased by 27% between 2014 and 2021, while plastic waste generation has decreased by 8% during the same period. However, the country’s waste recycling rate remains low, estimated at only 4.4% in 2020.

To meet its target of a 30% reduction in waste generation by 2030, China will need to significantly improve its waste collection, sorting, and recycling infrastructure, as well as promote greater public awareness and participation in sustainable waste management practices.

Waste management and plastic recycling in ASEAN countries

The ASEAN (Association of Southeast Asian Nations) region has been a hotspot for receiving plastic waste from developed countries, yet most of the countries in this region lack the necessary infrastructure and capacity for sound waste management.

Since 2017, several ASEAN countries, such as Thailand, Malaysia, and Vietnam, have restricted the import of plastic waste from Western nations and imposed bans on various single-use plastic products. However, the lack of sophisticated waste management systems in these countries has led to severe environmental impacts, with large amounts of plastic waste ending up in the oceans.

The ASEAN Secretariat has developed the “ASEAN Regional Action Plan for Combating Marine Debris in ASEAN Member States (2021–2025),” which outlines a comprehensive strategy to address the region’s plastic pollution challenge. This includes improving waste management infrastructure, strengthening policy and regulatory frameworks, and promoting circular economy practices.

To achieve the goals set forth in this action plan, ASEAN countries will need to mobilize significant investments, build institutional and technical capacities, and foster greater collaboration between governments, private sectors, and civil society organizations.

Collective commitment and innovative solutions

Addressing the plastic pollution crisis in Asia will require a collective, multi-stakeholder approach. Governments, private companies, and civil society organizations must work together to implement comprehensive waste management strategies, promote circular economy principles, and drive technological innovations in plastic recycling.

Some promising initiatives and solutions already emerging in the region include:

  • Extended Producer Responsibility (EPR): Implementing EPR schemes that hold manufacturers and brand owners responsible for the end-of-life management of their products, incentivizing them to design more recyclable and sustainable packaging.

  • Waste-to-Energy (WtE) technologies: Exploring advanced WtE processes, such as pyrolysis and gasification, to convert plastic waste into valuable fuels and chemical feedstocks, reducing the amount of plastic ending up in landfills or the environment.

  • Bioplastics and biodegradable alternatives: Developing and promoting the use of biobased, biodegradable, and compostable plastic alternatives to conventional petroleum-based plastics.

  • Innovative recycling solutions: Investing in new recycling technologies, such as chemical recycling and advanced mechanical recycling, to improve the quality and quantity of recycled plastic materials.

  • Circular economy collaboration: Fostering cross-border cooperation and knowledge-sharing on circular economy practices, including standardizing plastic waste treatment and operational systems.

  • Public awareness and behavior change: Launching nationwide awareness campaigns and educational programs to engage citizens in sustainable waste management practices, such as waste reduction, sorting, and recycling.

By embracing these innovative solutions and strengthening collective action, Asia can lead the way in tackling the global plastic pollution challenge and transitioning towards a more sustainable, circular economy for plastics.

Conclusion

The plastic pollution crisis in Asia is a complex and multifaceted challenge that requires a comprehensive, collaborative approach. While Japan, China, and ASEAN countries have taken important steps to address this issue through policy and regulatory measures, more concerted efforts are needed to meet their ambitious 2030 targets.

By investing in waste management infrastructure, promoting circular economy principles, and driving technological innovations in plastic recycling, these nations can not only reduce the environmental impact of plastic waste but also unlock new economic opportunities in the green economy. Ultimately, the success of these efforts will depend on the collective commitment and coordinated action of governments, businesses, and communities across the region.

As a seasoned expert in water and sanitation services, community engagement, and advocacy, I am optimistic about the potential for Asia to become a global leader in sustainable plastic waste management. Through continued research, policy development, and multi-stakeholder partnerships, the region can pave the way towards a future where plastic is no longer a threat to the environment, but rather a valuable resource in the circular economy.
