METHOD FOR PRODUCING FEED PIECES FROM SEWAGE SLUDGE

摘要

The invention relates to a method for producing feed pieces from sewage sludge (1) which is dried to a residual moisture in order to produce blanks (2) which maintain their shape. The aim of the invention is to configure a method of this type in such a way that the toxic proteins can be neutralised and the sewage sludge (1) can be effectively sterilised by subjecting the sewage sludge (1) to heat. To this end, the blanks (2) must be heated to a temperature above 120 DEG C for as long as is necessary to sterilise the blanks (2) and denature the proteins that they contain.
