The key to over-fertilization is P-concentration!
If you have too much phosphorus-rich waste and not enoughcropland nearby – consider incineration!

Sewage sludge to energy – State Zürich facility
Converts 100.000tonnes per year ofdewatered sludgefrom Zürich Stateto 7’000 MWh/yelectricity and35’500 MWh/y todistrict heating.
93.9% of Zürich’s population votedin favor of new mono sewage sludgeincinerator in a referendum!

Steam Dryer
Main advantages:
• Energy efficient• Completely closed process (no fugetive emissions)• Other substances/nutrients available in
the separated condensate• No need for a gas cleaning stage (odour,
emissions)• Low internal energy consumption• Mechanically few components• ATEX safe (steam environment)• Able to dry to to high levels (>90%)
