THE LANZATECH PROCESS
DETAILS
the world’s leading steel and mining company,
the carbon recycling company, and
Primetals Technologies,
a leading technology and service provider
to the iron and steel industry
today announce they have entered into
a letter of intent to construct
Europe’s first-ever commercial scale production facility
to create bioethanol from waste gases produced during
the steelmaking process.
The resulting bioethanol can cut greenhouse gas emissions
by over 80 per cent compared with conventional fossil fuels.
It will predominantly be used in gasoline blending,
but it can also be further processed into other products
such as drop in jet fuel.
The 47,000 ton ethanol/annum project,
sufficient to fuel half a million cars with ethanol blended gasoline,
will demonstrate the added value of recycling waste streams,
not only by reducing emissions at source,
hence reducing ArcelorMittal’s direct carbon footprint,
but by keeping fossil fuels in the ground
through the production of commodity chemicals and fuels
that would otherwise be made from oil.
Approximately 50 per cent of the carbon
used in the chemistry of steelmaking leaves the process
as carbon monoxide.
Today, this waste gas stream is either flared or used to heat and
power the steel mill. In either case, the carbon monoxide
is combusted and the resulting CO2 is emitted.
LanzaTech’s technology, however,
recycles the waste gases and ferments them with a proprietary microbe
to produce bioethanol.
Every ton of bioethanol produced, displaces 5.2 barrels of gasoline
as well as reducing ArcelorMittal’s CO2 emissions by 2.3 tons.
