A snapshot of our benchmark technologies
• Half of the world's pyrometallurgicalprimary copper is produced withOutotec® Flash Smelting
• One-third of the world’shydrometallurgical copper isproduced with Outotec® SX-EW
• Over one-third of the world’s sulfuricacid capacity runs on Outotectechnology
• Most of the world's iron ore pelletsare produced using Outotec'straveling grate process

Fluidized bed based processes
Incineration - gasification
Agenda
1. Introduction to Outotec2. Technology and expertise3. Motivation4. Resources & processes5. Challenges
Outotec has beenranked twice* to be3rd most sustainable
of all listed companies ofthe world !Corporate Knights,
World Economic Forum DavosAnnual Conferences
* In 2013 and 2015 (and in TOP 10 in 2014)

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%)
