What happens if the equipment still has an economic value after several transfers but there is no eligible recipient for donation, nor any action to which to transfer it again?

The obligation to transfer or donate remains valid until the equipment has been fully depreciated.

Therefore, if at the end of the action to which the transfer was made the equipment is not fully depreciated and donation or transfer are not possible anymore, ECHO could either recover the remaining value according to the applicable depreciation rules, or, if justified, grant the partner a derogation to keep the equipment.
