This item essentially consists of deferred items from the sale of claims resulting from minimum waste volume rights. Due to a contractual arrangement, the Group is obligated to accept a certain volume of waste. It provides for the Group to be paid for a pre-determined minimum waste volume, irrespective of the actual volume delivered. The claims from this minimum waste volume through 30 September 2021 were sold, and an interest rate of 4.2868% was agreed upon with the contract partner. This amount was recognised as a liability under advances received.
