Japan's Annual Plastic Waste: A Troubling Reality

Japan is one of the largest producers of plastic products, with plastic packaging and single-use plastic products being the most manufactured. The country produces more plastic per capita than China and the rest of Asia combined. While the disposal volume of plastic waste in Japan has decreased, it remains at over eight million metric tons annually, with plastic packaging accounting for 67.6% of all plastic waste generated in the country. In 2018, the Japanese government unveiled a proposal to reduce the country's 9.4 million tonnes of plastic waste a year by 25% by 2030.

Plastic packaging waste

Japan is one of the largest producers of plastic waste in the world, with an annual plastic waste generation of over eight million metric tons. Plastic packaging waste accounts for a significant portion of this, with Japan being the second-largest generator of plastic packaging waste per capita after the USA. In 2014, Japan generated 32.4 kg of plastic packaging waste per capita, which is considerably higher than the global average.

Plastic packaging is commonly used in Japan due to its association with hygiene and cleanliness. The popularity of takeaway food boxes, vending machine beverages in PET bottles, and excessive packaging for souvenirs and gifts contributes to the high volume of plastic packaging waste. The Japanese culture of "presentation and respect" when giving gifts often results in excessive and deceptive packaging, as observed in a study where removing unnecessary packaging from souvenir boxes led to a 25-40% reduction in volume.

To address the plastic packaging waste issue, Japan has implemented measures such as the 1995 Packaging Waste Recycling Law, which mandates municipalities to organize recycling efforts. However, the recycling rate for plastic waste in Japan is primarily driven by thermal recycling, which involves incinerating plastic waste for energy recovery. While this method is considered recycling, it contributes to air pollution and greenhouse gas emissions. Only a small portion of the plastic waste is reused to manufacture new plastic products.

There are ongoing efforts to reduce plastic packaging waste in Japan. The government introduced a levy on plastic carrier bags in 2020, encouraging shoppers to bring their own bags. Additionally, some local governments and companies are working together to reduce single-use plastic products, and customers are increasingly using reusable containers for food and other items. Japan has also set a goal for all plastic packaging to be either reusable or recyclable by 2025.

Despite these efforts, Japan's plastic packaging waste problem persists. The country's high consumption of single-use plastics and reliance on incineration as a recycling method contribute to environmental concerns. To achieve long-term sustainability, Japan will need to transition from incineration to methods that promote the reuse of plastic materials or reduce overall plastic consumption.

Plastic waste exports

Japan is one of the largest producers of plastic waste in the world, with an annual plastic waste production of over eight million metric tons. The country has historically exported huge amounts of plastic waste, mainly to other Asian countries. However, exports decreased significantly after 2017 when China banned plastic waste imports. This forced Japan to find more sustainable solutions to reduce and manage its plastic waste.

The recycling rate of plastic waste in Japan has increased in recent years, reaching 87% in 2023. While this is much higher than the recycling rate of regular waste in Japan, it is important to note that this figure includes thermal recycling, where plastic is incinerated to generate energy. Despite the use of filtering technologies, the incineration process still produces greenhouse gas emissions that contribute to air pollution and global warming. Only a small amount of plastic waste is reused to manufacture new plastic products.

To reduce plastic waste generation, the Japanese government implemented several measures. In July 2020, the government prohibited all retail shops from distributing free plastic shopping bags. Some local governments and companies are also working together to reduce single-use plastic products. For example, Kanagawa announced the "Kanagawa No Plastic Waste Declaration," aiming to achieve zero plastic waste by 2030. Toyama Prefecture stopped providing free shopping bags to customers and began charging for them in 2008, significantly increasing the percentage of people who brought their own bags.

In 2019, the Japanese government announced a plan to prohibit the export of dirty plastic waste that cannot be recycled. This was in response to the Basel Convention, which regulates waste moving across borders. Japan also plans to strengthen regulations and request agreements with trading partners on exporting plastic waste.

Plastic recycling rate

Japan is the second-largest generator of plastic packaging waste per capita in the world, with plastic packaging accounting for 67.6% of all plastic waste generated in the country. This is 20% more than the world average. The country's total plastic waste generation is over eight million metric tons annually, with some sources stating that it is as high as 9.4 million tons per year.

Japan's official "recycling rate" of end-of-life plastics is 84%, which is much higher than the recycling rate of regular waste in the country, remaining low at around 20%. However, this figure includes burning plastic as a form of energy, which may be misleading. Over half of the plastic that is "recycled" is incinerated, which produces greenhouse gas emissions that contribute to air pollution and global warming. Only a small amount of plastic waste is reused to manufacture new plastic products.

In 2018, the Japanese government unveiled a proposal to reduce the country's plastic waste by 25% by 2030. The government has also mandated that retail shops charge for plastic shopping bags, with some local governments and companies working together to end the use of plastic straws and shopping bags. In 2020, the government prohibited all retail shops from distributing free plastic shopping bags.

Japan has implemented various measures to promote resource conservation, including the development of eco-friendly technologies and energy-saving regulations. The country has strict waste separation and recycling laws, with local municipalities responsible for ensuring compliance. The government also offers subsidies and incentives to companies that engage in resource-conserving practices.

Plastic waste reduction initiatives

Japan is the second-largest generator of plastic packaging waste per capita in the world, with an annual disposal volume of over eight million metric tons. Plastic packaging accounts for 67.6% of all plastic waste generated in Japan, with other plastics, such as straws, accounting for 16.2%, and PET bottles making up 14.4%.

To address this issue, Japan has implemented several plastic waste reduction initiatives:

Government Initiatives

The Japanese government has taken several measures to reduce plastic waste. In 2019, the government announced the Resource Circulation Strategy for Plastics, which aims to introduce biomass plastics more extensively by 2030. The Act on Promotion of Resource Circulation for Plastics was enacted in 2021 to promote the reduction, collection, and recycling of plastic waste. This act outlines environmentally friendly guidelines for the design and manufacturing of plastic-containing products. Additionally, the government has prohibited retail shops from distributing free plastic shopping bags, with some local governments going a step further by mandating charges for plastic bags.

Corporate Initiatives

Major companies like Kao and Shiseido have stopped selling products containing microbeads, and some brands have also discontinued the use of microplastics in their products.

Local Initiatives

Several local governments and communities in Japan are actively working to reduce plastic waste. For example, Kanagawa has declared a goal of zero plastic waste by 2030 and is collaborating with businesses to eliminate plastic straws and shopping bags. Toyama Prefecture has successfully encouraged 95% of its customers to bring their own bags by charging for plastic bags since 2008. Kamikatsu Town in Tokushima Prefecture has achieved an impressive waste recycling and composting rate of 81% through the dedication of its residents, who separate waste into 45 categories.

Educational Initiatives

Okayama Municipal Minannishi Kominkan is working with local residents and students to raise awareness about environmental issues and reduce marine litter. They are conducting clean-up activities and experiments to reduce river litter, fostering future leaders who are conscious of sustainability.

International Cooperation

Japan is also sharing its plastic waste reduction initiatives with other Asian countries. The Japan International Cooperation Agency (JICA) is developing projects in Thailand and the Philippines for the recycling of marine plastics and the introduction of waste-to-energy power generation plants.

Plastic microbeads in products

Japan is one of the largest producers of plastic products, with plastic packaging and single-use plastic products being the most common. The country produces more plastic per capita than China and the rest of Asia combined. While the disposal volume of plastic waste in Japan has decreased, it remains at over eight million metric tons annually. Plastic waste pollution has become a major environmental issue, posing a threat to both human and animal health as harmful chemicals from microplastics end up in the food chain.

Plastic microbeads are solid plastic particles made of synthetic polymers, measuring between 5μm and 1mm in diameter. They are added to a range of products, including cosmetics, personal care items, and cleaning products, to work as exfoliants, bulking agents, and abrasives. They are also used for the controlled release of active ingredients and to prolong a product's shelf life.

Microbeads are often too small to be filtered out by sewer systems, so they end up in oceans, lakes, and rivers, contributing to plastic pollution. They are not biodegradable, so once they enter water systems, they are impossible to remove. This has led to concerns about the impact of microbeads on the environment and marine life, with organizations like Greenpeace calling for a ban on their use in commercial products.

Some companies in Japan, such as Kao and Shiseido, have stopped selling products containing microbeads, but some brands still use them. Consumers can avoid purchasing products with microbeads by checking the raw materials listed or using apps like Beat the Microbead, which scans product barcodes to detect the presence of microplastics.
