A public comment period for the draft opinion on the future of the waste disposal system (Ministry of the Environment) was held from January 9 to February 7, 2026. This allows us to see what the government plans to prioritize in the future waste disposal system. The content has been discussed by experts in advisory councils and subcommittees of the Ministry of the Environment, and it is expected that initiatives related to these topics will accelerate in the fiscal year 2026. Three issues have been raised as challenges: 1. Measures regarding yards 2. PCB disposal 3. Disaster waste Particularly regarding the first issue, traditionally, valuable materials were not considered waste, and the storage yards of valuable purchase operators were not subject to guidance or regulation by the authorities under the Waste Management Law. However, in recent years, there have been many incidents of unsafe practices and environmental pollution at the yards of purchase operators, which seems to be prompting countermeasures. Some local governments (such as Chiba Prefecture) have already begun to enact ordinances on this matter. At this stage, there are no obligations or regulatory items for waste generators, but it is anticipated that compliance will become increasingly important in the selection of buyers for valuable materials in the future.

Due to the revision of the Waste Management and Public Cleansing Law, the obligation to provide information on Type 1 designated chemical substances to waste generators will be enforced starting January 1, 2026. In preparation for this enforcement, the "Guidelines for Providing Waste Information" are scheduled to be revised to the third edition, and this has been confirmed on the Ministry of the Environment's website. In addition to changes to the WDS format in response to the legal revision, there are also modifications and additions to the guidelines themselves, reflecting changes from previous concepts. We have published a preliminary and brief explanation of these changes in our company’s website column. Main revisions to the guidelines: 1. Addition of content regarding the amendments to the enforcement regulations. 2. Emphasis on the importance of two-way communication between waste generators and waste treatment operators in information transmission. 3. Revision of the WDS format. Looking at aspects unrelated to the legal revisions, there is an intention to ensure safety at disposal sites and prevent accidents, rather than merely providing one-sided information. If anyone is having trouble creating WDS documents, please feel free to consult with our company.

The amendment to the Waste Management Act regulations was promulgated on April 22, 2025. The additional content resulting from the amendment consists of the following two points. The changes will significantly impact practical operations, so this information is directed toward those who may not yet be aware. 1. Mandatory provision of information on Type 1 designated chemical substances - Effective date: January 1, 2026 [Overview] As part of the contract, businesses handling Type 1 designated chemical substances must include information on the Type 1 designated chemical substances (including the percentage contained in products, residues, etc.). 2. Addition of reporting items for disposal contractors in electronic manifests - Effective date: April 1, 2027 [Overview] Previously, only information on the final disposal location was required, but now, if a portion of the residue is being recycled after intermediate processing, it will be necessary to report all routes, allowing the waste generator to verify this information.
