Furthermore, Japan generates huge amounts of electronic waste. Since technology is advancing faster and the consumer demand for electronic devices keeps growing, electronic devices are often disposed of after a few years of use. Japan was among the first Asian countries to implement an electronic waste recycling program, but electronic waste still contributes to waste pollution as it is often dumped illegally.
With the incineration rate of municipal waste amounting to close to 75 percent, incineration remains the most widely used waste treatment method in Japan, as it can easily reduce the volume of waste. Despite filtering technologies, which avoid the release of huge amounts of fumes, the incineration process produces greenhouse gases that contribute to air pollution and global warming.
The recycling rate of Japan's total waste has remained at around 20 percent throughout the past decade and therefore represented one of the lowest recycling rates among industrialized countries. In contrast, the recycling rate of plastic waste increased to 86 percent in recent years. However, thermal recycling was the main method to recycle plastic waste. With this method, waste is incinerated to generate energy.
The remaining waste is disposed of at landfills. Even though the volume of final waste disposal declined, Japan is facing a shortage of landfill sites as the remaining capacity of landfill sites is decreasing.
To reduce the volume of plastic waste, the government prohibited all retail shops from distributing free plastic shopping bags. As of July 2020, all shops, convenience stores, and restaurants must charge a fee for plastic bags. These measures started to show an effect as the majority of Japanese citizens stated in a survey that they tried to avoid the use of disposable plastic bags since the fee has been introduced.
Waste treatment in Japan
In Japan, waste is usually sorted into categories by citizens before it is collected and is not picked up if the strict waste separation rules are not followed. Plastic, paper, PET bottles, aluminum, and glass are collected separately to be recycled. Most of the waste collected in Japan is processed in incineration or recycling facilities or is disposed of at landfills.With the incineration rate of municipal waste amounting to close to 75 percent, incineration remains the most widely used waste treatment method in Japan, as it can easily reduce the volume of waste.

Measures to reduce waste
Since 2004, the Japanese government promotes the so-called 3R initiative, aiming to build a sound material-cycle society. The initiative encourages businesses and citizens to focus on the importance of reducing, reusing, and recycling waste.To reduce the volume of plastic waste, the government prohibited all retail shops from distributing free plastic shopping bags.
