Issy-les-Moulineaux / France Energy-from-Waste Plant
Isséane – environmentally friendly plant
with a view of the Eiffel Tower.
The Isséane energy-from-waste facility is located in a densely populated Parisian suburb
on the banks of the River Seine with a view of the Eiffel Tower. Attractive architecture and
environmentally friendly technology were the core concerns of the planners.
With its red exposed masonry, the plant –
located only a few kilometers away from downtown
Paris – blends harmoniously into the surrounding
urban architecture. Although it is 52 meters high,
only 21 meters of the building are visible, roughly
equivalent to the height of a six-story residential
property. The remaining 31 meters are underground.
The planners also placed emphasis on making
sure that no plume would rise from the stack of
the plant in Issy-les-Moulineaux, one of the most
densely populated conurbation communities
in Europe.
The builder.
Syctom, owner of the plant, is an intercommunal
association established to process the household
waste of Greater Paris. It operates three waste
treatment plants that serve 85 French communities
with a total of 5.3 million inhabitants. Isséane,
the most modern of the three facilities, handles the
waste generated by 1.1 million residents of
22 communities in the Paris region.
Modern technology defines new benchmarks
in France.
The Isséane energy-from-waste plant consists of
two process trains with a rated capacity of 30.5 t/h
each for a total of 460,000 t/a. The waste receiving
area and the combustion system are subterranean,
so the plant produces neither noise nor odor
emissions.
The waste is incinerated on two five-zone Hitachi
Zosen Inova grates; the first three zones are watercooled with Aquaroll® to assure optimised waste
burnout. The plant is designed for a calorific bandwidth of 8 to 12 MJ/kg waste. An integrated combustion control system with an infrared camera
makes it possible at all times to quickly and reliably
adjust the combustion parameters to rapidly
changing waste compositions. The hot incineration
gases are routed through a secondary combustion chamber to a four-pass boiler where they are
cooled from 1100°C to 180°C.

District heating for 80,000 homes.
All of the steam that is produced (200 t/h) goes
to an extraction condensing turbine. About half of
this energy is fed into the district heating network
that serves 80,000 households. This corresponds
to some 110,000 tons of heating oil. In other words,
the waste produced by seven households can heat
one family’s home. The electricity tapped from the
turbogenerator is used primarily for plant power;
the rest is exported to the grid.

Environmentally friendly thanks to
efficient flue gas treatment.
The flue gas treatment section is composed of
several stages – an electrostatic precipitator,
a dry sorption reactor with injection of sodiumbicarbonate and lignite coke, a fabric filter and
a selective catalytic reduction (SCR) for NOx
removal. With its design, the plant outperforms the
strict EU and local directives in every respect and
establishes new ecological benchmarks in France.
