I found a well-used belt for fixing luggage in each company's air cargo. It is believed that the discarded items flowed into the local market after their useful life passed. Normally, air cargo has strict safety rules, and there seems to be a rule that even if it looks like it can be used, it will be disposed of.
However, it is still usable as much as it is used in normal life. We believe that it is our role to make good use of these resources. In addition to not knowing when it will be available, a great many processes such as cleaning and sorting are required. In addition to being too inefficient, planned production is also difficult. Because it is a material that major companies do not touch first.
