Cleaning – Disposal of waste material (2)
According to [Billm2002], a maximum of 40 – 50 % of the waste material from sewers, and a maximum of 15 – 25 % of the waste material from catch basins can be classified as recyclable substances. The re-utilization potential of the waste material from the cleaning of sewers is limited to a fraction of the mineral solids.
