A payment order and reminder were issued to the executer, using the expenses required for the construction that had already been finalized, but the delinquency was delinquent. For this reason, heavy equipment such as construction equipment left in the disposal site and property (deposits, real estate, etc.) owned by former officers were seized and exchanged by public auctions, etc., and about 7 million yen has been collected so far.

We conducted a survey of waste disposal companies and received proposals from 25 companies for voluntary removal of waste.
