Japan's Plastic Problem: Causes And Environmental Impact

Japan has a significant plastic waste problem, with the average Japanese person using 450 plastic bags and 183 PET bottles per year. Japan's plastic recycling rate is 84%, but this figure includes burning plastic as a form of energy, which is not environmentally friendly. Japan has historically exported large amounts of plastic waste to other Asian countries, but this decreased after China banned plastic waste imports in 2017. Japan's obsession with hygiene and customer service, as well as deceptive packaging, contributes to excessive plastic use. However, there is a growing awareness of the plastic problem, and some companies are investing in plastic recycling facilities and alternative materials.

Japan's high recycling rate of plastic waste

Japan has a sophisticated waste management system and one of the highest per-capita plastic consumption rates in the world. The country has a strong tradition of recycling and resource conservation, rooted in ancient cultural beliefs and practices, and supported by modern government policies. Japan's recycling rate for plastic waste is 84-87%, but this includes burning plastic for energy, which may be misleading as it is not traditional recycling.

Japan's extensive recycling system is built on the country's progressive circular economy model, which aims to reduce waste by extending the life cycle of products. The country's unique culture, dating back to when the West was first making contact with distant lands, has influenced its high recycling rate. Japan's citizens typically sort their waste into approximately nine different categories before collection. Plastic, paper, PET bottles, aluminium, and glass are collected separately for recycling.

Despite Japan's high recycling rate, the country faces challenges due to its overwhelming use of single-use plastic. Japan's plastic waste problem is driven by its high per-capita plastic consumption rate, with the average Japanese person using 450 plastic bags and 183 PET bottles annually. The country's preference for perfectly presented and preserved products, as well as its obsession with cleanliness, contributes to excessive packaging and plastic waste.

To address these issues, Japan has implemented policies such as charging for plastic bags, which has successfully reduced their use. The country is also exploring the development of biodegradable plastics and alternative materials. Additionally, grassroots movements and social ventures are raising awareness about the plastic problem and promoting sustainable solutions.

While Japan's recycling rate is impressive, it is important to note that a large portion of its plastic waste is incinerated, raising environmental concerns. Japan has been working to improve incineration technology to reduce its environmental impact, but the emission of gases contributes to global warming.

Plastic burning as a form of energy

Japan has a significant plastic waste problem. The country's official "recycling rate" for end-of-life plastics is 84%, but this figure includes burning plastic as a form of energy, which some argue is misleading. Indeed, over half of the plastic that is "recycled" in Japan is incinerated, with very little domestic infrastructure for traditional recycling.

Burning plastic for energy, also known as thermal recycling or incineration, is promoted as a solution to the world's plastic waste crisis. It is argued that this method can generate electricity and reduce landfill waste. Sweden, Germany, Norway, and some other European countries have adopted incineration as a waste management method, burning up to half of their waste for power.

However, burning plastic for energy has significant drawbacks and is not widely considered a sustainable or environmentally friendly practice. Incineration facilities are expensive to build and operate, requiring steady waste input to make them worthwhile. This encourages increased plastic production and consumption to feed the machine, creating a never-ending cycle of burning and producing plastics. Additionally, burning plastic releases pollutants such as dioxins, heavy metals, and other toxic substances, posing health risks to nearby communities, particularly low-income ones.

While some environmental activists agree that burning plastic can supplement mechanical recycling, it is not a complete solution. The economics of building new waste-to-energy facilities are challenging, and the technology for making fuels from plastics is still in the early stages of development.

Therefore, while burning plastic as a form of energy may seem appealing, it is not a panacea for plastic waste issues. Composting, reusing, repairing, and traditional recycling are all more energy-efficient and environmentally friendly alternatives to incineration.

Lack of domestic recycling facilities

Japan's plastic waste problem is partly due to a lack of domestic recycling facilities. Japan has very few domestic facilities for recycling plastic, which is why it resorts to burning or exporting its plastic waste. Burning plastic waste is not environmentally friendly, as it contributes to air pollution and global warming, despite incineration plants having filtering technologies to prevent the release of large amounts of greenhouse gases.

In the past, Japan exported large amounts of plastic waste to other Asian countries, particularly China. However, in 2017, China banned plastic waste imports from Japan, forcing Japan to find more sustainable solutions to manage its plastic waste. This has led to a decrease in exports and an increase in the recycling rate of plastic waste in Japan.

While Japan has a high official "recycling rate" of end-of-life plastics, at 84%, this figure includes burning plastic as a form of energy generation, which may be misleading. Over half of the recycled plastic is incinerated, with only a small amount of plastic waste being reused to manufacture new plastic products. This means that Japan needs to develop methods to reuse plastic materials instead of burning them or reduce the overall use of plastic products to become more sustainable.

There is a growing awareness of the plastic problem among Japanese consumers, with an increase in grassroots movements and social ventures. Some companies are also investing in plastic recycling facilities to meet the rising demand for more sustainable practices. For example, Daiei Kankyo Holdings, a recycling company based in Kobe, opened a 1.5 billion yen ($13.8 million) plant in Osaka in 2020. Additionally, the Japanese government has implemented initiatives such as the Resource Circulation Strategy for Plastics in 2019, with the goal of making all plastic packaging reusable or recyclable by 2025.

Excessive packaging and wrapping culture

Japan's excessive packaging and wrapping culture is driven by its obsession with hygiene and pride in "omotenashi" or customer service. This results in meticulous wrapping and rewrapping of items in multiple layers of plastic. For instance, a purchase of bagels might come individually wrapped in sealed plastic bags and then be packed together in another plastic bag before being placed inside a third plastic bag with the rest of one's shopping. This culture of excessive packaging and wrapping is not unique to the food industry, as evidenced by the discovery that masks bought in Japan were each individually wrapped in plastic.

The problem of deceptive packaging in Japan is also prevalent, as an experiment revealed that when the product was reorganised without the deceptive packaging, a 25-40% reduction in volume was achieved. This not only reduces plastic waste but also paper waste, as outer boxes are often made of paper. Additionally, the total box size would decrease, requiring fewer trucks for transportation and thus reducing fossil fuel usage.

While Japan has a high plastic recycling rate of 84%, this figure is misleading as it includes burning plastic as a form of energy generation, known as thermal recycling. In reality, Japan has very few domestic facilities for recycling plastic, which is why it often resorts to burning or exporting its plastic waste. However, burning plastic contributes to air pollution and global warming, and there is no guarantee that exported plastic is recycled properly.

To address the issue of excessive packaging and wrapping, Japan is taking steps towards more sustainable solutions. The government launched the Resource Circulation Strategy for Plastics in 2019, aiming for all plastic packaging to be reusable or recyclable by 2025. Japanese companies are also working on replacing plastic with paper for packaging materials, despite the higher production cost of paper. Additionally, grassroots movements and social ventures are advocating for a reduction in single-use plastics, and companies like Daiei Kankyo Holdings are investing in plastic recycling facilities.

Government and grassroots initiatives to reduce plastic waste

Japan has been taking steps to address its plastic waste problem through various government and grassroots initiatives. At the local level, several cities have taken the lead in reducing plastic waste. For example, Kitakyushu City has a history of overcoming pollution through cooperation between industry, academia, government, and the private sector. The city has promoted the establishment of plastic recycling companies and introduced mandatory charges for plastic bags. Similarly, Okayama City has been working with local residents and students on marine litter reduction projects, including clean-up activities along the Sasagase River.

Kameoka City in Kyoto Prefecture was one of the first local governments to make a Zero Plastic Waste Declaration, aiming for zero waste from single-use plastics by 2030. The city has actively worked towards this goal by signing agreements with companies and encouraging the use of reusable water bottles and thermoses. Toyama City is also looking to expand its unique model of tackling plastic waste by reducing single-use plastics, promoting recycling and reuse, and improving waste management.

At the national level, the Japanese government has enacted legislation to address plastic waste. In 2021, the Act on Promotion of Resource Circulation for Plastics was passed, specifying measures to circulate plastic resources at different phases of plastic-containing products, from design to recycling. The government has also set environmentally friendly guidelines for plastic-containing products at the design and manufacturing stages. Additionally, the Ministry of Foreign Affairs launched the MARINE Initiative, which aims to reduce marine plastic litter and support developing countries in waste management.

Grassroots movements have also played a crucial role in driving change. Campaigns such as Refill emphasize reusing bottles, while A Plastic Planet urges plastic-free aisles in supermarkets. There is also a growing awareness among consumers, with initiatives like "No Plastic Japan" promoting metal straws and MyMizu, Japan's first free water refill app, helping reduce single-use plastic bottles.
