History of Rakkestad waste to energy

Building the new system for recovery of

energy from waste, the company

Østfold Energi uses household and

industrial waste for steam production,

which is delivered to 3 major

companies in the region. The system is

build as a 4 MW Steam plant, with a

yearly combustion of approximately

10.000 Ton mixed household and

industrial waste.

The Rakkestad plant has a maximum

effect of 4.2 MW and approximately

7500 operation hours a year.

Since the commissioning in December 2005, the combustion plant has worked faultlessly and

continuously delivered approximately 30 GMh a year.

One of the major advantages of the Weiss system is, that the operation is fully automatic and only

manned in the day time. During weekends the system is unstaffed which results in substantial savings

relating to resources.

The combustion system has an advanced cleaning system, which ensures that the demands in the EU

Waste Incineration directive as well as the national demands easily are kept.

Whereas, Waste or Biomass based fuel are used for generation of Thermal heating / Power generation

– the cost savings on fossil fuel are tremendous, and one of the great benefits are to be independent of

the volatility of the energy prices.

The

investment pays off in a few years --- the profit will hereafter grow.

Green energy – environment

Burning waste products instead of

stowing it, the energy is recovered

and converted to energy. Thereby

a double climate effect is

obtained, since the production of

energy from bi-product results in

not only a substantial reduction of

the consumption of fossil fuel, but

also a reduction of the CO2

emissions.

The flue gas is cleaned by the

latest technique in filter systems.

WEISS fulfill all national and local

emissions requirements

WEISS Range of boiler capacity
