Mechanical-Biological Treatment Plant in Hanover, Germany – Experience in Mechanical Processing, Anaerobic Digestion and Refuse Derived Fuel Quality –
The Hanover mechanical-biological treatment (MBT) plant can look back on 15 years of operator´s experience. The mechanical treatment facility has been working largely without any issues due to the simple technique and the comfortable redundancy and design. The biological treatment facility faces growing damage due to ageing of materials, which is accelerated by microbiological attack, and corrosive and abrasive ingredients in the residual waste. Comprehensive maintenance, renovation and replacement measures are planned.
The cost-effectiveness of MBT technology compared to
the incineration of waste is on trial. Therefore, in Hanover changing treatment
concepts are discussed. The demand for replacement of primary energy carrier by
energy-intensive industrial plants (e.g. paper mills, cement kiln) is growing.
One option of MBT is the intensified production of refuse derived fuel (RDF)
and less deposit to landfill. Another is the conversion from residual waste
treatment to biowaste treatment. MBT with fermentation stage give a positive
contribution to the carbon footprint, mainly due to the utilization of biogas. MBT
technology provides an important contribution to the resource economy.
