Kernrechtsfrage
Whether the appellant was the holder of the waste and thus obliged to remove it under environmental law.
Extrahierter Entscheid
Yes. A holder is the person who actually has control over the waste; a tenant operating a storage/sorting site can be the holder even if the waste pre-existed the tenancy or the land later changed ownership.
Extrahierte Begründung
The company exercised factual control over the site and ran an activity akin to waste storage and treatment. The change of ownership did not remove that control, and the court did not need to examine any private-law duties of the landowner toward the tenant.
