In the delivery area, newly arrived waste is weighed, registered and tipped into the refuse pit, where it is temporarily stored. The waste is also mixed in the refuse pit.

The refuse pit is designed to hold sufficient fuel for several days of combustion as waste is only delivered during the day and on working days but the plant operates around the clock.

The tipping hall and refuse pit are closed buildings to prevent dust and odours from escaping into the environment. In addition, air is continually extracted from the pit to maintain a negative pressure. The extracted air serves as combustion air for the combustion system.
