Japan Grapples with Trash Bag Shortage Amid Hoarding and Resale Crisis

Japan is facing an unexpected crisis as a shortage of designated trash bags has led to hoarding and resale on auction sites, mirroring a similar phenomenon seen in Korea. The shortage, which has been observed in various parts of the country, has prompted local governments to introduce temporary measures to mitigate the issue. In the city of Ichihara, located in the Chiba Prefecture near Tokyo, residents are now allowed to use ordinary plastic bags for combustible waste until the end of next month.

The decision to suspend the requirement for designated bags was made after more than 60 complaints were filed by residents who were unable to purchase the bags. Local authorities have attributed the shortage to a surge in demand, which has distorted the market. According to a city official, suppliers have secured volumes similar to previous years, but the sudden increase in demand has led to hoarding and resale of the bags on auction sites. This has, in turn, caused anxiety among residents, leading to continued sellouts.

Similar responses are being observed in other regions of Japan. Ryugasaki City in Ibaraki Prefecture has decided to allow the use of ordinary transparent plastic bags until the end of June, while Yonabaru Town in Okinawa Prefecture is distributing alternative bags that are distinguished only by color, without printed text. The shortage of designated trash bags is not a nationwide issue in Japan, as many areas, including Tokyo's 23 wards, do not require volume-based trash bags. However, the situation has drawn attention due to the supply instability and hoarding problems faced by some municipalities that have adopted designated bags.

A similar phenomenon was observed in Korea, where controversy over the hoarding of volume-based trash bags led to a full survey by the government. The survey revealed that municipalities held inventories ranging from at least one month to up to six months' worth of bags. The government responded by reallocating production volumes to regions facing raw material shortages. The root cause of the issue has been identified as instability in the supply of raw materials, particularly polyethylene, which is extracted from naphtha. Japan's dependence on the Middle East for naphtha has led to supply chain disruptions and price surges.

Against this backdrop, some regions in Japan have introduced purchase limits to prevent hoarding. Online posts showing off hoarded bags have also spread, heightening market anxiety. The government is working to build a response system to minimize price spikes and hoarding. In the long term, the industry is exploring alternative materials that are less dependent on petroleum. Recently, volume-based trash bags made from biodegradable materials, such as polyhydroxyalkanoates (PHA) derived from plant-based ingredients like sugar cane, have been developed. These materials can decompose in soil and the ocean and are relatively less affected by oil price fluctuations.

The development of biodegradable trash bags is a significant step towards reducing Japan's dependence on petroleum-based materials. As the country continues to grapple with the trash bag shortage, it is likely that more municipalities will adopt alternative materials and implement measures to prevent hoarding and resale. The crisis has also highlighted the need for a more sustainable approach to waste management, with a focus on reducing waste generation and increasing recycling rates. As Japan works to address the current shortage, it is an opportunity for the country to rethink its approach to waste management and move towards a more environmentally friendly and sustainable future.

In conclusion, the trash bag shortage in Japan is a complex issue that is driven by a combination of factors, including supply chain disruptions, hoarding, and resale. While the government and industry work to address the current shortage, it is essential to consider long-term solutions that prioritize sustainability and reducing waste generation. By adopting alternative materials and implementing measures to prevent hoarding and resale, Japan can work towards a more environmentally friendly and sustainable approach to waste management.
