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.
