Japan's Plastic Recycling Efforts: An In-Depth Analysis

Japan has the second-highest plastic packaging waste per capita in the world, with the average Japanese person using 450 plastic bags and 183 PET bottles annually. The country produces around 10 million tons of plastic a year, 78% of which is discarded as waste within a year. Japan has a high plastic recycling rate of 84%, but only 23% of this is recycled materially, and 4% is recycled chemically. The remaining 70-75% is incinerated, which is considered by many countries as non-recyclable. Japan has implemented measures to reduce plastic waste, such as charging for plastic bags, but its recycling systems are overwhelmed by the volume of plastic.

Japan's plastic recycling rate is 84%, but most is incinerated

Japan has the second-highest plastic packaging waste per capita in the world, with the average Japanese person consuming 450 plastic bags and 183 PET bottles annually. In total, the country produces around 10 million tons of plastic a year, 78% of which is discarded as waste within a year.

Japan's plastic recycling rate is officially reported to be 84%, one of the highest in the world. However, this figure is misleading as up to 70% of this "recycled" plastic is incinerated for energy through thermal recycling, a process that has the same negative environmental impact as burning fossil fuels. Only 23% of plastic waste is reused for its materials, and 4% goes into chemical recycling, which is uneconomic due to the high energy and resources required.

Despite the high recycling rate, plastic waste continues to pollute Japan's beaches and seas. A 2016 Environment Ministry survey showed that 23% of the plastic bottles collected on the shores of Tsushima Island off Nagasaki Prefecture originated in Japan, with the rest coming from neighbouring countries.

To address its plastic waste problem, Japan has introduced measures such as mandating businesses to charge customers for plastic bags and promoting the use of bioplastic bags. The government has set a target of reducing single-use plastic by 25% by 2030 and is encouraging local governments and companies to reduce plastic waste. However, these requests are not mandatory, and it is unclear if the targets will be achieved.

Japan produces 10 million tons of plastic a year, 78% is waste within a year

Japan produces 10 million tons of plastic annually, with 78% of it being discarded as waste within a year. This makes Japan the third-highest producer of plastic in the world. Despite a national reputation for efficiency, Japan struggles with properly disposing of plastic waste. Plastic packaging and single-use plastic products are the leading plastic products manufactured in the country. The popularity of takeaway food boxes, as well as vending machines with beverages in PET bottles, contributes to the generation of plastic waste. As a result, plastic waste pollution has become a significant environmental issue in Japan, posing a threat to both human and animal health due to the presence of harmful chemicals from microplastics in the food chain.

Japan has been addressing its plastic waste problem through various measures. Since July 2021, the government has mandated businesses to charge customers for plastic bags, encouraging the reduction of single-use plastic consumption. Additionally, Japan has implemented recycling requirements, and it is mandatory to separate trash and recycle plastics. However, the recycling rate in Japan remains low, with only about 23% of collected plastic being materially recycled and a mere 4% recycled chemically. The rest is burned, a process that is frowned upon in many other countries due to its negative environmental impact.

The World Wildlife Fund (WWF), in collaboration with the Wild Bird Society of Japan, has developed educational materials to raise awareness about the ecological consequences of plastic waste. They recommend the adoption of a ""circular economy," in which all raw materials are recycled, similar to the approach being pursued by the EU. Japan has also been shipping a portion of its plastic waste to Southeast Asian countries since 2017, but this has contributed to the maritime plastic pollution in those regions.

While Japan faces an uphill battle to reduce its plastic consumption and improve its recycling rates, there is potential for reform. Simple individual actions, such as picking up trash, reducing the use of PET bottles, and supporting sustainable businesses, can collectively have a significant positive impact on the environment and marine ecologies.

Plastic bag consumption in Japan is very high, with an average of 450 bags per person annually

Japan has the third-highest plastic production in the world, generating about 10 million tons of plastic annually. Despite a national reputation for efficiency, most properly disposed of plastic waste is treated carelessly. In 2021, the country produced 8.24 million tons of plastic waste, with plastic bags accounting for 1.2% of this total.

However, Japan still generates the world's second-largest amount of plastic waste per person. The country has been shipping part of its plastic waste to Southeast Asia since 2017, contributing to maritime plastic flows. Only 18% of plastic waste is recycled domestically in Japan, with 23% recycled materially and 4% recycled chemically. The remaining waste is burned, which is considered by many countries as non-recyclable due to its negative environmental impact.

To further reduce plastic waste, the Japanese government has implemented additional measures. In April 2022, business operators were mandated to reduce waste from 12 single-use plastic products, such as spoons and forks. The city government of Kameoka, Kyoto Prefecture, became the first municipality to ban all business operators from providing plastic bags to shoppers. These initiatives demonstrate Japan's commitment to reducing plastic consumption and promoting environmental sustainability.

Plastic bottles are recycled at a higher rate than other plastics, at 85% in 2018

Japan's plastic footprint is one of the largest in the world, with the country producing around 10 million tons of plastic a year, making it the third-highest producer globally. Despite this, Japan is a world leader in recycling plastic bottles, with a rate exceeding 80%, far higher than in Europe or the United States. In fact, in 2018, almost 85% of Polyethylene terephthalate (PET) bottles were reportedly recycled in Japan, with the rate for PET bottle recycling reaching 84.8% in fiscal 2017. This success can be attributed to two main factors. Firstly, the Japanese plastic bottle industry sets strict guidelines from the manufacturing stage to ensure that the bottles produced are easy to recycle. Secondly, a law has been implemented for bottle separation, collection, and reuse.

The high recycling rate of plastic bottles in Japan is particularly notable when compared to the overall recycling rate of plastic waste in the country, which has remained low at around 20% over the past decade. This discrepancy can be partly explained by the fact that Japan has been shipping a significant portion of its plastic waste overseas, with 70% of its total exports of plastic waste going to China in 2017. However, when China banned plastic waste imports in the same year, Japan was forced to shift its export strategy and increase exports to other countries such as Indonesia and Vietnam.

To address the issue of plastic waste, Japan has implemented several measures. Since July 2021, the government has mandated businesses to charge customers for plastic bags, and it is already mandatory for citizens to separate their trash and recycle plastics. Additionally, the government unveiled a proposal in 2018 to reduce the country's plastic waste by 25% by 2030, and there is a growing number of grassroots movements and social ventures focused on reducing plastic consumption.

Despite these efforts, Japan's plastic waste problem persists, and the country faces a shortage of landfill sites as the remaining capacity for final waste disposal is shrinking. The incineration of municipal waste, which has an incineration rate of around 75%, remains the most widely used waste treatment method in Japan. However, burning plastic is frowned upon in many places and is considered to have the same negative environmental impact as fossil fuels.

Overall, while Japan has made some progress in reducing and recycling its plastic waste, particularly in the case of plastic bottles, there is still much to be done to address the country's large plastic footprint and the environmental impact it has on marine ecosystems.

Japan has been working to reduce plastic waste, with a goal of a 25% reduction by 2030

Japan has been taking steps to address its significant plastic waste problem. The country produces around 10 million tons of plastic waste per year, the third-highest amount globally, with only 18% recycled domestically. While Japan recycles 85% of its plastic, well over half of that is burned to generate electricity or exported abroad, with only 20% turned into new products.

To combat this issue, the Japanese government has set an ambitious goal: to reduce single-use plastic waste by 25% by 2030. This target has caused concern among local governments, which will be responsible for collecting the plastic. A government panel of experts has proposed institutional reforms to achieve this goal, including re-categorising plastic waste as "plastic resources" to emphasise their potential for recycling. Municipal governments will be tasked with collecting and sorting these resources, with guidelines provided by the national government.

The new system, expected to be implemented by fiscal 2022, aims to integrate household garbage and industrial waste to reduce plastic waste overall. However, the requests made to local governments and companies are not mandatory, casting doubt on whether the target will be met. The success of the initiative will depend on the cooperation of local governments and their ability to implement effective waste sorting and collection methods.

Some municipalities, like Setagaya Ward, are already taking proactive measures. Setagaya Ward residents can bring their plastic items to designated locations twice a month, collecting around 7 tons of plastic. However, they face challenges in determining the cost and logistics of sorting and collecting plastic waste under the new system.

Japan's efforts to reduce plastic waste extend beyond government initiatives. Consumers are encouraged to reduce plastic consumption, choose products with minimal plastic packaging, and carry reusable beverage containers and shopping bags. The World Wildlife Fund (WWF), in collaboration with the Wild Bird Society of Japan, has developed educational materials to raise awareness about the ecological impact of plastic waste. These collective efforts are vital in Japan's journey towards reducing plastic waste and protecting the environment.
