Fifth Step: the four core points of the Hafner technology
Combustion technology
Combustion
The Hafner Waste to energy plants
are essentially based on four main categories:
Depending on the waste heat value, two
different combustion technologies are used.
Grate firing with an integrated steam boiler
plant is used for low to medium-calorific waste.
For highly caloric waste, a rotary kiln with
afterburning chamber and waste heat boiler is
used.
Energy recovery
The plant technology is designed to use
upwards of 65% of the thermal energy (R1 -
as defined according to Annex II of EU
DIRECTIVE 2008/98/EC on Waste) including
power generation, district heating or
cooling and process steam.
Flue gas cleaning
In the tradition of conventional simple
flue gas cleaning, Hafner relies on a
completely dry flue gas cleaning process
with double flue gas filtration for
increased dust retention and more
efficient pollutant minimization. The
achieved emission values are thus far
below the EU limit values.
Material recovery
From the slag residues of combustion
valuable materials are recovered by
further treatments and different selection
processes.

Fifth Step: Hafner technology - a life cycle to be proud of
• Small energy control center guarantees high levels oftransparency towards the local authorities and theircitizens in this way.
Waste cycles can be better understood by the consumer.
No Waste Water. At the end of the process, the plant merely expelsslag and filtered waste gases.
The plant extracts more than 80% metals from the slag which issubsequently available for a new economic cycle.
High quality of metals and glasses extracted from the thermaltreatment.
Undesired coatings and adhesions are also removed during theprocess.
Remaining materials are also recyclable – such as rubble which isused by the building materials sector or in road construction.
Fifth Step: the advantages of the Hafner technology
Low investment costsconsequently pleasantly low
operating costs.
Extracting of valuable energies in the form of electricity, heat and
refrigerants
Use of state of the art and environmental-friendly
technology.
CO2 reduction through the replacement of fossil fuels during the incineration process.
CO2 reduction by low transportation by contrast with centralized waste sites.
Utilization of the energy introduced with an efficiency level of 80 per cent. Waste is thus considered and “declared” as fuel according to the EU Directive.
CE / TÜV certification of the modular plant has been performed.
Emission values fulfill the provisions ofthe European Community and morefar reaching even stricter nationalrequirements

• THE WORLDWIDE CASE FOR WASTE TO ENERGY
Energy from waste worldwide (1)
Assuming that 84.07% of the world's well-produced waste is household waste, an assumed 70% of the waste with an average calorific value of 8,372 kJ/kg will be allocated to the Waste to Energy incinerators.
MSW World Wide
The remaining 15.93% of the world wide produced waste is hazardous waste, of which 30% of the waste with an average calorific value of
12,558 kJ/kg is again provided for the Waste to Energy incinerators.

All this is possible to reduce the large amount of waste in
the world and to make a contribution to climate protection.
